  • Ensure URL Is Indexed
    Technical SEO checklist-0001 URL is indexedUse Google Search Console → URL Inspection to confirm “Indexed?” status, Google-selected canonical, and last crawl. site: is only indicative—don’t rely on it alone. If not indexed: remove noindex, allow crawling in robots.txt, include in XML sitemap, add internal links, and click “Request indexing”. URL Inspection Tool
  • Ensure Important Content Is Indexed
    Technical SEO checklist-0002 Important content indexedOnly index valuable templates/pages (categories, PDPs, articles). Check GSC Page indexing report, noindex, canonical, robots.txt, and sitemap status. Important pages need internal links, successful render, and 200 OK. MozBar
  • Page Returns 200 (OK) Status Code
    Technical SEO checklist-0003 Returns a 200 status codeVerify 200 OK for the canonical URL and variants (http/https, www/non-www, trailing slash). Use a crawler (Screaming Frog/Ahrefs) and curl -I. Avoid JS redirects and any 4xx/5xx. Plerdy SEO Analyzer
  • Allow Indexing via Meta Robots / X-Robots-Tag
    Technical SEO checklist-0004 Indexable by robots meta tag and X-robots-tagIndexable pages should be index, follow (default; explicit tag optional). For PDFs/images, use X-Robots-Tag in response headers. Don’t mix noindex with canonical to another URL. Plerdy SEO Analyzer
  • Do Not Block the URL in robots.txt
    Technical SEO checklist-0005 URL not blocked by robots.txt fileCheck robots.txt and the robots.txt report in Google Search Console. Remember: a Disallow stops crawling but doesn’t guarantee deindexing, and it prevents Google from seeing page-level meta tags. Don’t block templates intended to be indexed. Use Page indexing / URL Inspection to confirm whether a URL is blocked, and, if needed, test with a crawler (e.g., Screaming Frog) or an online validator.
  • Declare Sitemap Location in robots.txt
    Technical SEO checklist-0006 Sitemap file location defined in robots.txtAdd Sitemap: https://example.com/sitemap.xml (multiple allowed). Ensure the sitemap returns 200 and lists only canonical, indexable URLs. Include only if it reliably reflects the last significant update; otherwise, omit it to avoid misleading signals.
  • Submit Sitemap to Search Engines
    Technical SEO checklist-0007 Sitemap file submitted to search enginesSubmit sitemap in Google Search Console and Bing Webmaster Tools. Respect limits (≤50k URLs or ≤50MB per file); use an index sitemap if needed. Monitor coverage/errors and keep lastmod current.
  • Make the URL Discoverable via Internal Links/Navigation
    Technical SEO checklist-0008 URL is discoverable via internal links/navigationAvoid orphan pages: add 1–2 contextual internal links with descriptive anchors; keep click depth ≤3. Links must be crawlable (no nofollow, not JS-only). Add to nav/breadcrumbs where relevant.
  • Serve Content at a Single Canonical URL
    Technical SEO checklist-0009 Content is available at a single, canonicalized URLUse self-canonical on the primary version and 301 from duplicates (params/UTMs, http↔https, www↔non-www, slash variants). Don’t canonicalize pagination to page 1. Keep hreflang and canonicals consistent.
  • Align Google-Selected and Declared Canonical
    Technical SEO checklist-0010 Google-selected canonical matches user-selected canonical In GSC URL Inspection, compare “Google-selected canonical” to your rel=canonical. If different, strengthen signals: 301 from duplicates, internal links to canonical, canonical URLs in sitemap, remove noindex/blocks on the canonical page.
  • Avoid Canonical/Indexing Mixed Signals
    Technical SEO checklist-0011 No canonical/indexation mixed-signal errorsDon’t combine noindex with canonical to another URL; don’t canonicalize to blocked/4xx/noindex pages; avoid duplicate canonicals. Keep meta robots, X-Robots-Tag, robots.txt, and canonical aligned across mobile/desktop.
  • Use a Friendly URL Structure
    Technical SEO checklist-0012 Friendly URL structure Keep URLs short, readable, lowercase, words separated by hyphens: bestsite.com/category/product-name. Enforce trailing-slash policy, avoid unnecessary params/IDs, and keep a stable hierarchy.
  • Do Not Block Critical CSS/JS/Images in robots.txt
    Technical SEO checklist-0013 Important CSS, JS, and images not blocked by robots.txtEnsure Google can render pages: don’t block /wp-includes/, /static/, or CDN assets. Check Rendered HTML in GSC and PageSpeed/Lighthouse. Remove patterns like Disallow: /*.css$.
  • Use Correct Redirect Codes (No Chains/Loops)
    Technical SEO checklist-0014 Are there any redirects other than 301? Use 301/308 for permanent, 302/307 for temporary. Eliminate chains/loops; update internal links to the final URL. Verify with Screaming Frog/redirect checkers.
  • Eliminate 5xx Server Errors
    Technical SEO checklist-0015 Are there any 5xx errors? Set up uptime/log alerts (e.g., UptimeRobot). In GSC, check Page indexing → Server errors (5xx). Fix timeouts, resource limits, app exceptions. Add health checks and rollback plans for deployments.
  • Provide Meaningful Image Alt Text
    Technical SEO checklist-0016 Are images ALT tags in use? Add descriptive alt to informative images; use empty alt="" for decorative ones. Avoid keyword stuffing. Audit via Screaming Frog/Lighthouse and by exporting IMG without alt from your crawler.
  • Validate HTML (W3C)
    Technical SEO checklist-0017 Is the website W3C Compliant? Valid, semantic HTML improves rendering, accessibility, and parser reliability (e.g., structured data). Use validators to catch broken markup. It’s not a direct ranking factor—focus on speed, content quality, and UX.
  • Analyze Logs & Manage Crawl Budget
    Crawling checklist - log files & crawl budget?Analyze server logs (Googlebot UA): frequency, 404/soft-404s, parameterized URLs, infinite spaces. Prioritize key sections via internal links/sitemaps, curb noisy parameters, and streamline navigation. Crawl budget matters on large sites.
  • Noindex System & Search Pages (/search, /cart, /checkout, /login)
    Noindex System & Search Pages (/search, /cart, /checkout, /login)Add meta robots noindex,follow on internal search and system pages; exclude them from sitemaps. Prefer auth on sensitive areas. Check via GSC URL Inspection, Page Indexing report, and a crawler’s Indexability report.

💡 Meta & Structured Data, Page-level & elements analysis

  • Keep Page Titles Concise (Avoid SERP Truncation)
    Technical SEO checklist-0018 Are all page titles under 65 characters? (570 pixels) Aim for concise titles that won’t truncate in SERPs (≈600px on desktop, ~50–60 chars is a good proxy). Put the primary topic up front, brand at the end. Audit with a crawler (Plerdy, Screaming Frog, Ahrefs) and a SERP-width preview. Fix overlong titles and remove fluff.
  • Avoid Overly Short Titles (<30 Characters)
    Technical SEO checklist-0019 Are any Page Titles under 30 characters?Flag titles under ~30 chars—they’re often too vague to match intent. Enrich with the primary keyword + qualifier (model, use case, region). Report short titles via crawler (Plerdy/Screaming Frog) and expand them to improve clarity and CTR.
  • Remove Duplicate Page Titles (Handle Canonical/Pagination Correctly)
    Technical SEO checklist-0020 Are any page titles being duplicated without canonical/pagination?Crawl for duplicate titles and map each URL to a unique intent. For true duplicates, de-duplicate content, consolidate with 301s, or set a clear canonical. For pagination, keep distinct titles (e.g., “Category — Page 2”) and don’t canonicalize page 2+ to page 1.
  • Detect & Resolve Keyword Cannibalization
    Technical SEO checklist-0021 Any signs of keyword cannibalization?Use GSC to find queries where multiple URLs compete. Decide the “owner” page, consolidate overlapping content, adjust internal links/anchors to favor it, and de-optimize or retarget the others. If needed, merge and 301 to the strongest URL.
  • Place Primary Keyword Early in the Title
    Technical SEO checklist-0022 Is the primary keyword/phrase close to the start?Lead with the main topic for relevance and scanning. Keep it readable; avoid stuffing. Brand at the end is fine. Verify positions via crawler exports (Plerdy/Screaming Frog) and spot titles where the focus term is buried.
  • Make Titles Accurately Describe the Content
    Technical SEO checklist-0023 Are page titles descriptive of the page content?Ensure each title reflects on-page content and search intent. Avoid clickbait or generic labels (“Home,” “Products”). Crawl for mismatches and rewrite to set correct expectations; align H1, intro, and primary query.
  • Ensure Every Page Has a Title
    Technical SEO checklist-0024 Are any page titles missing?Export pages with missing/empty <title> and fix them first (templates, 404s, filters). Add safeguards in CMS to prevent publishing without titles. Watch for auto-generated duplicates from faceted navigation.
  • Write Unique, Compelling Meta Descriptions
    Technical SEO checklist-0025 Are all Meta Descriptions unique and descriptive?Meta descriptions aren’t a ranking factor, and Google may rewrite them, but good ones improve CTR. Write a clear, truthful summary that matches intent and includes a soft CTA. Keep them unique per URL and aligned with on-page copy.
  • Fill Missing Meta Descriptions (High-Value Pages First)
    Technical SEO checklist-0026 Are any Meta Descriptions missing?Prioritize meta descriptions for key pages (money pages, top articles). Where omitted, Google will pull a snippet—often fine for long-tail pages. Use crawler reports to find missing ones and add concise, relevant summaries.
  • Eliminate Duplicate Meta Descriptions
    Technical SEO checklist-0027 Are any Meta Descriptions being duplicated without canonical/pagination?Duplicate descriptions hurt clarity and CTR (not a “duplicate content” penalty, but poor UX). Give each page a distinct summary that reflects its unique value. For pagination/variants, include differentiators (page number, filter).
  • Keep Meta Descriptions ~150–160 Characters (Clear & Relevant)
    Technical SEO checklist-0028 Are any Meta Descriptions below 70 characters?Very short snippets under-inform users. Target ~150–160 chars so the idea fits without truncation; focus on usefulness over exact length. Match search intent and on-page content; avoid keyword stuffing.
  • Do Not Use Meta Keywords
    Technical SEO checklist-0029 Are Meta Keywords in use?Meta keywords are not considered important for SEO because search engines, such as Google, no longer use them as a ranking factor in their algorithms. Instead, search engines use the content of a page to determine its relevance to a user's query.
  • Implement & Validate Structured Data (Where Relevant)
    Structured data checklist - coverage & validity?Implement and validate Organization/Person, Breadcrumb, Article, Product/Offer/Review, FAQ, and Sitelinks Search Box where relevant. Keep markup consistent with visible content and fix errors/warnings.
  • Add Social Preview Tags (Open Graph & Twitter Cards)
    Add Social Preview Tags (Open Graph & Twitter Cards)Add og:title, og:description, og:image (~1200×630) and twitter:card=summary_large_image for every indexable page; localize where you use hreflang. Validate with Facebook Sharing Debugger, Twitter Card Validator, and by checking HTML source.

✍ Content

  • Ensure Readable Font Sizes
    Technical SEO checklist-0030 Are all fonts large enough to read clearly? Use a base font size of ≥16px with line-height ~1.4–1.7. Check legibility across devices and languages. Test real pages (not just components) and verify Core Web Vitals aren’t hurt by custom fonts (preload critical, use font-display: swap). Good readability reduces pogo-sticking and improves engagement.
  • Make Hyperlinks Clear and Distinct
    Technical SEO checklist-0031 Are hyperlinks clear?Links should be visually distinct (underline by default or a clearly different color) with sufficient contrast and a visible focus state. Use descriptive anchor text (not “click here”), avoid nofollow internally, and provide a visited state. Clear links help users navigate and concentrate link equity.
  • Ensure Sufficient Text Contrast
    Technical SEO checklist-0032 Could font color be considered too light?Meet at least WCAG AA contrast (normal text 4.5:1, large text 3:1). Test dark mode and overlays on images/video. Insufficient contrast tanks readability and can increase bounces. Fix with palette tweaks, backgrounds, or text-shadow only if necessary.
  • Differentiate Primary vs. Supplementary Content
    Technical SEO checklist-0033 Are there clear primary and supplementary content types? Make main content obvious; separate supplementary elements (nav, sidebars, related items, ads). Label ads/sponsored blocks and avoid blending them with main content. Clear hierarchy improves comprehension and aligns with quality rater guidelines.
  • Balance Evergreen and Fresh Content
    Technical SEO checklist-0034 Is content Evergreen or Fresh?Maintain evergreen hubs that earn links over time, then layer timely updates (new data, screenshots, features). Show datePublished/dateModified where relevant and update titles/intros when the year changes. Don’t “fake-refresh” with trivial edits.
  • Eliminate Low-Value/Thin Pages
    Technical SEO checklist-0035 Eliminate Low-Value/Thin PagesWord count isn’t a ranking factor—value is. Identify pages with little unique main content, near-duplicates, empty category/tag pages, or boilerplate. Consolidate, improve, or noindex them; add internal links and unique purpose before reindexing.
  • Publish an Up-to-Date Privacy Policy
    Technical SEO checklist-0036 Does the website carry an up-to-date Privacy Policy? Link Privacy (and Terms) in the footer; keep it current with data practices (GDPR/CCPA, cookies, opt-outs). It’s a trust signal for users and reviewers; pair with a contact route and brand info (address, company, VAT where relevant).
  • Eliminate Internal Duplicate Content
    Technical SEO checklist-0037 Is there any duplicate content internally?Audit duplicates from parameters, faceted nav, print pages, HTTP/HTTPS, and www variants. Canonicalize to a single URL, block crawl of junk parameters, and 301 consolidate when appropriate. Keep only one indexable version per intent.
  • Address External Duplicates/Syndication
    Technical SEO checklist-0038 Is there any duplicate content externally? If you syndicate, use canonical back to the original (or noindex on partners). For scraped copies, strengthen internal linking, publish first, and request removal when needed. Focus on unique analysis, data, and visuals.
  • Avoid Scraped/Plagiarized Content
    Technical SEO checklist-0039 Is any content scraped from external sources? Don’t republish others’ content verbatim. Quote briefly with attribution, then add unique commentary, data, or experiments. Use canonical when republishing your own work elsewhere.
  • Provide a Clear, Easy-to-Find Contact Page
    Technical SEO checklist-0040 Is the contact page easy to find and use?Link “Contact” in the header/footer; include email/phone, form, and business details (NAP). Add spam protection and expected response times. For local businesses, add map and opening hours; consider LocalBusiness schema.
  • Run Content Gap Analysis
    Technical SEO checklist-0041 Content Gap AnalysisMap target topics vs. competitors and SERP features. Fill gaps with pages that match intent (informational vs. commercial), then connect them via internal links to pillar pages. Use crawler/GSC exports to prioritize by opportunity and difficulty.
  • Review Copy Quality and Content Classification
    Technical SEO checklist-0042 Copy and classification checksFix tone, clarity, and factual accuracy; avoid jargon bloat. Classify content consistently (categories, tags) and prevent low-value tag archives from indexing. Add summaries, intros, and clear subheads for scanning.
  • Check Grammar and Spelling
    Technical SEO checklist-0043 Has page grammar and spelling been checked?Proofread headlines, CTAs, tables, and image captions. Typos erode trust and can confuse searchers. Build editorial checks into your publishing workflow; run language-specific QA for localized pages.
  • Use Hierarchical Headings and Semantic HTML
    Technical SEO checklist-0044 Content organized with hierarchical HTML tagsUse a clear heading outline (one primary H1, then H2/H3), lists for steps, tables for comparisons, and descriptive alt text. Add a table of contents for long guides. Semantic structure improves comprehension and machine parsing.
  • Target Topics and Queries (Not Just Keywords)
    Technical SEO checklist-0045 Target Topics and Queries (Not Just Keywords)Cover the user intent thoroughly: include entities, FAQs, and supporting subtopics. Place the main query in the title/H1/intro naturally. Avoid stuffing—opt for clarity, examples, and original assets (diagrams, screenshots, data).
  • Follow Google Search Essentials (Quality/Spam Policies)
    Technical SEO checklist-0046 Content doesn't violate Google's Quality GuidelinesAvoid auto-generated fluff, doorway pages, hidden text, link schemes, and deceptive UX. Demonstrate expertise, cite sources, and provide helpful, original information aligned with Search Essentials.
  • Avoid Intrusive Interstitials (Especially on Mobile)
    Technical SEO checklist-0047 Avoids intrusive interstitialsLegal notices (cookie consent, age gates) are fine when minimal. Avoid full-screen popups that block main content on landing. Delay promos until interaction or time-on-page; provide easy dismissal.
  • Limit Heavy Above-the-Fold Ads
    Technical SEO checklist-0048 Avoid heavy ads above the foldKeep primary content visible on load. Compress ad scripts, lazy-load below-the-fold, and cap ad density. Watch CLS/LCP in Core Web Vitals; reserve space to prevent layout shifts.
  • Avoid Critical Content in iFrames
    Technical SEO checklist-0049 Content isn't loaded in an iFrameGoogle can index iframes, but content counts for the iframe source URL, not the parent. Don’t put essential copy/links only in an iframe. If embedding tools/video, allow bot access to the source and add contextual text on the page. Set width/height to prevent CLS; loading="lazy" is fine.
  • Ensure Lazy-Loaded Content Is Discoverable
    Technical SEO checklist-0050 Lazy-loaded content is visible in the viewportUse native lazy-loading for images/iframes; for content lists, load initial items server-side and expose links/JSON in HTML. Avoid requiring user interaction for critical content. Test rendering with a crawler and URL Inspection.
  • Make Infinite Scroll Crawlable (Paginated URLs)
    Technical SEO checklist-0051 Supports paginated loading for infinite scrollProvide unique, linked URLs for each page/state (e.g., ?page=2) using anchor links or “Load more” that updates the URL (pushState). Ensure each page is reachable without JS and is internally linked. Consider a “view all” option when feasible. (Don’t rely on deprecated rel="next/prev".)
  • Show Publication and Updated Dates
    Technical SEO checklist-0052 Current publication and updated datesDisplay datePublished and meaningful dateModified when you actually update substance (not typos). Use structured data where relevant (Article/BlogPosting). Don’t spam “Updated” badges without changes.
  • Show Author and Publisher Clearly
    Technical SEO checklist-0053 Clear who the author and/or publisher IsAdd an author box with credentials, links to profiles, and editorial standards. Include an About page. Use sameAs and Organization markup where appropriate. Transparency supports trust and expertise.
  • Avoid Content Flagged by SafeSearch
    Technical SEO checklist-0054 Content doesn't trigger Google Safe Search filtersIf your audience is general, avoid explicit imagery/terms and ensure thumbnails/snippets are safe. Use proper tagging and context for sensitive topics. Remember SafeSearch can filter results for opted-in users.
  • Avoid Hidden Text Meant to Manipulate
    Technical SEO checklist-0055 Hidden textDo not hide keyword-stuffed text (e.g., same-color text, off-screen positioning). Hiding for legitimate UX (tabs/accordions) is fine if content is visible on interaction and not deceptive.
  • Do Not Cloak
    Technical SEO checklist-0056 CloakingServe the same primary content to users and crawlers. Personalization/A/B tests are OK when experiences are equivalent. Avoid UA/IP-based swaps meant to manipulate rankings.
  • Avoid Doorway Pages
    Technical SEO checklist-0057 Doorway pagesDon’t create many near-duplicate pages targeting slight geo/keyword variations that funnel to the same destination. Build robust hub pages or localized pages with real unique value.
  • Avoid Excessive Ad Density
    Technical SEO checklist-0058 Are there too many ads on any pages?Keep ads reasonable, clearly labeled, and secondary to content. Measure scroll depth and time-to-content; reduce ad slots if they impede reading or tank Core Web Vitals.
  • Do Not Overuse Pop-Ups
    Technical SEO checklist-0059 Does the website bombard you with popups?Cap the frequency, delay initial promos, and never block main content on entry—especially on mobile. Provide clear close controls and avoid deceptive patterns.
  • Use Clear Calls to Action
    Technical SEO checklist-0060 Does the website carry clear Call to Action?Each page should have a primary CTA (text + prominent button) and supporting CTAs where relevant. Make it specific (“Start free trial”), place it high and repeat at logical points. Test copy and placement.
  • Use a Clear H1 Per Page
    Technical SEO checklist-0061 Does each page have a clear H1 tag?Prefer one descriptive H1 that matches the page’s primary intent. HTML5 allows multiple H1s, but a single main H1 is simpler and less error-prone. Align H1 with title and intro; avoid empty/duplicate H1s across templates.
  • Use H2 Subheadings for Structure
    Technical SEO checklist-0062 Are H2's being used across the site?Break content into logical sections with H2/H3s for scannability. Keep headings descriptive and avoid stuffing keywords. Headings should reflect the outline users expect from the query.
  • Publish People-First Content (AI-Assisted Is Fine)
    Technical SEO checklist-0062 AI content detect Search systems don’t reward or punish “AI-detected” content; they reward helpful, original work. If you use AI, edit for accuracy, add unique insights, examples, and first-hand experience. Cite sources, update regularly, and ensure factual correctness.
  • Strengthen Authorship & E-E-A-T Signals
    Content checklist - authorship and E-E-A-T?Add author bios/credentials, About/Editorial pages, and sameAs links to real profiles. Cite reliable sources, disclose monetization/ads, keep articles updated, and weave in hands-on expertise (screenshots, data, case studies).

🗝 Keyword analysis

  • Do Keyword Research and Set Benchmarks
    Technical SEO checklist-0063 Site keyword research for Benchmarks Define topics and intent (informational, commercial, local). Build clusters with head terms + long-tails and map them to pages. Record baselines: GSC clicks/impressions/CTR/position, non-brand vs. brand, share of voice vs. key competitors, and SERP features present. Revisit quarterly; prioritize high-value, realistic wins.
  • Own Your Branded Query (Homepage Ranks #1)
    Technical SEO checklist-0064 Brand search - Does the homepage come up #1 when searched? Search your exact brand name and variants. The homepage should rank #1 with sitelinks; knowledge panel and social profiles should be accurate. Fix issues by consolidating duplicates (301), using Organization schema, aligning brand name in titles/H1, consistent NAP, and linking to official profiles. Remove confusing “brand + login/help” pages from title dominance if needed.
  • Is there evidence of keyword duplication or overuse?
    Technical SEO checklist-0065 Is there evidence of keyword duplication or overuse? Scan titles/headings/body for repeated head terms that read unnaturally. Replace repetition with synonyms/entities, answer sub-questions, and tighten sentences. Keep anchors varied and human. If multiple pages chase the same query, retarget one to another topic and adjust internal links to reduce competition.
  • Use the Primary Topic in the Title
    Technical SEO checklist-0066 Are keywords in Page Titles?Lead with the core topic; add a useful qualifier (model, use case, region). Keep concise to avoid truncation and avoid repeating the brand twice. Expect occasional Google rewrites—ensure H1/intro match the title so the chosen snippet stays relevant.
  • Include the Primary Keyword in the H1
    Technical SEO checklist-0067 Are keywords in H1? Use a single, clear H1 per page and include the primary keyword naturally—ideally near the start if it reads well. Align the H1 with the <title> and opening paragraph so they all reflect the same intent (they don’t have to be identical). Avoid stuffing; let H2/H3s cover related entities and subtopics. Audit by exporting H1s in a crawler (Plerdy/Screaming Frog) and fix empty, duplicate, or mismatched H1s across templates.
  • Include the Primary Keyword (or Close Variant) in an H2
    Technical SEO checklist-0067 Are keywords in H2?At least one H2 should naturally include the primary keyword or a close variant (e.g., singular/plural, stem, or a question form). Don’t stuff the same head term into every H2—use related entities for the rest. Keep headings readable and aligned with search intent. Audit by exporting H2s with a crawler (Plerdy/Screaming Frog) and fix pages where no H2 reflects the core topic.
  • Include the Primary Keyword in the Meta Description (for CTR)
    Technical SEO checklist-0068 Are keywords in Meta Description? Meta descriptions aren’t a ranking factor, but including the primary keyword (or a close variant) once—ideally near the start—can bold in SERPs and lift CTR. Write a truthful ~150–160-character summary that matches on-page content and search intent; add 1–2 natural supporting terms, not stuffing. Keep each description unique per URL, use the page’s language, and include a clear value prop + soft CTA. For templates (e.g., product/category), dynamically pull specifics (price, stock, rating). If Google rewrites your snippet often, tighten the opening paragraph and headings so the auto-snippet still contains the keyword and value.
  • Include the Primary Keyword in Body Copy
    Technical SEO checklist-0069 Are keywords in the main page document? Use the primary keyword naturally throughout the body—not just headings. Mention it early, then support with related entities, synonyms, examples, and FAQs. Avoid density targets; write for clarity and intent satisfaction. Link to relevant internal pages and ensure the visible copy (not only images/widgets) contains the term.
  • Include the Primary Keyword in the Opening Paragraph
    Technical SEO checklist-0070 Make sure that your target keyword is included in your opening paragraph State the page’s topic in the first 1–2 sentences and include the primary keyword (or close variant) once near the start if it reads naturally. Align with the <title> and H1; don’t force awkward phrasing. For templates (product/category), surface concrete detail (model, brand, use case) alongside the keyword.

🖇 Backlinks

  • Assess Backlink Health & Authority
    Technical SEO checklist-0071 Backlink health & ScoreEvaluate quality over “scores.” Benchmark referring domains growth, topical relevance, link types (editorial vs. UGC/sponsored), dofollow/nofollow mix, language/geo, and spam percentage vs. competitors. Prioritize earned, contextually relevant links on authoritative pages; don’t chase vanity metrics.
  • Identify Spammy Referring Domains
    Technical SEO checklist-0072 Spammy domains Flag obvious spam (hacked sites, link farms/PBNs, casino/adult/pharma, gibberish anchors, auto-generated pages). Try removal or let Google ignore them; use disavow only for clearly manipulative links you can’t remove or if you have a manual action risk.
  • Use a Disavow File Only When Necessary
    Technical SEO checklist-0073 Has disavow file been created and checked?Disavow is a last resort—not routine hygiene. Use it for unremovable, unnatural links pointing at you (paid, manipulative, or part of link schemes). Prefer domain-wide entries, keep evidence of outreach, review quarterly, and avoid over-disavowing legitimate sites.
  • Keep Anchor Text Natural and Varied
    Technical SEO checklist-0074 Anchor Text UseHealthy profiles mix branded, URL, generic (“learn more”), and partial-match anchors; exact-match should be rare and editorial. Watch for sitewide exact-match, foreign-language spam, or identical anchors across many domains. Internally, use descriptive anchors that match the target page’s intent.
  • Monitor and Reclaim Lost Backlinks
    Technical SEO checklist-0075 Backlinks lost Track “lost” links (page removed/noindexed, link removed, redirect changed). Reclaim by restoring/redirecting the target URL, updating the linker to the new URL, or recreating a relevant resource. Prioritize high-authority referrers and 404s with link equity.
  • Fix Broken Backlinks (Redirect or Update Link)
    Technical SEO checklist-0076 Broken BacklinksBroken backlinks, or dead links, can also negatively impact user experience and potentially harm your search engine rankings.
  • Check for Unnatural Link Concentration from Single Domains
    Technical SEO checklist-0077 Are there large number of backlinks from 1 domain or more? Many links from one domain can be normal (navigation/sitewide citations) but have diminishing returns. Investigate paid/footer/widget links and repetitive exact-match anchors. If necessary, remove or add rel="nofollow sponsored" and work on diversifying referring domains.
  • Do Not Optimize for Domain Age
    Technical SEO checklist-0078 Domain AgeDomain age itself isn’t a ranking factor. Older domains often rank due to accumulated quality content and links—not age. Don’t buy “aged” domains for ranking alone; invest in content, UX, and authoritative links.
  • Track Total Backlinks (Quality Over Quantity)
    Technical SEO checklist-0079 Total Number of Backlinks Ahrefs is an all-in-one SEO tool that makes exploring a website's backlink profile quick and easy. Monitor new vs. lost links and link velocity, but judge by source quality and context. Filter out junk (spam, scraped, sitewide noise). A few strong editorial links beat thousands of weak ones.
  • Track Total Linking Root Domains
    Technical SEO checklist-0080 Total Number of Linking Root Domains Referring domains correlate better with authority than raw link counts. Aim to grow unique, relevant domains across diverse sites/pages. Avoid inflating totals with sitewide links from the same domain.
  • Earn Topically Relevant Backlinks to the URL
    Technical SEO checklist-0081 URL has relevant backlinks Pursue links from pages about your topic (industry publications, resource pages, data/research, case studies). Provide link-worthy assets (original data, tools, visuals). Ensure the surrounding context and anchor naturally fit the target page.
  • Ensure the Disavow File Doesn’t Include Valuable Links
    Technical SEO checklist-0082 Disavow file doesn't block important links Audit the disavow list for mistakes. Never disavow high-quality or relevant referrers; remove erroneous entries and resubmit. Keep a change log and revisit after major link audits or migrations.
  • Create and Optimize Social Profiles Where Your Audience Is
    Technical SEO checklist-0083 Create social media profiles on the platforms your target audiences hang out on Claim consistent handles; complete bios with value prop and site link (UTMs ok). Most social links are nofollow, but profiles can improve brand SERPs, knowledge panels, and referral traffic. Keep branding, NAP, and imagery consistent; post regularly.
  • Publish on LinkedIn Articles (and Company Page)
    Technical SEO checklist-0084 Get on LinkedIn Pulse Repurpose articles as LinkedIn posts/articles/newsletters to reach your audience. Link back to the full guide on your site (expect nofollow). Include a byline, resources, and a clear CTA; don’t duplicate entire long-form verbatim if cannibalizing your own page.
  • Pitch and Appear on Relevant Podcasts
    Technical SEO checklist-0085 Do guest podcasting Target shows your buyers follow, pitch a specific, unique angle, and prep assets. Request a show-notes link to a helpful resource page (with UTM). Add the episode to your media page and repurpose quotes/clips for further reach.

📱 Mobile

  • Ensure Responsive Layout (Mobile-First)
    Technical SEO checklist-0086 Responsive checkUse fluid grids, flexible media, and CSS breakpoints starting from small screens. Test key templates on common devices. Avoid desktop-only hover states; ensure touch-friendly controls and readable type (base ≥16px, line-height ~1.5). Verify no horizontal scroll and content fits the viewport.
  • Avoid Intrusive Interstitials on Mobile
    Technical SEO checklist-0087 Popups/InterstitialsDo not block main content on entry. Keep consent/age gates minimal and dismissible. Delay promos until interaction or time-on-page; cap frequency; provide a clear close target. Ensure overlays don’t trap focus and don’t tank Core Web Vitals.
  • Keep Mobile Page Weight Light
    Technical SEO checklist-0088 Mobile Page Size Minimize JS/CSS, defer non-critical scripts, and compress assets. Serve only what’s needed above the fold; code-split routes; inline critical CSS. Aim for fast LCP and low JavaScript execution time. Remove unused libraries, trackers, and heavy widgets.
  • Use Responsive Images
    Technical SEO checklist-0089 Image useServe the right image per viewport with srcset/sizes. Provide width/height (or aspect-ratio) to prevent CLS, and lazy-load below-the-fold images. Prefer loading="lazy" and decode off the main thread (decoding="async").
  • Optimize Image Formats & Compression
    Technical SEO checklist-0090 Image optimization Use modern formats (WebP/AVIF) with fallbacks, compress aggressively (visually lossless), and strip metadata. Deliver via CDN with caching and HTTP/2/3. Alt text is for accessibility/SEO context; the title attribute is optional and not required for optimization.
  • Serve Properly Sized Images
    Technical SEO checklist-0091 Image resizingAvoid upscaling or sending desktop-size images to mobile. Generate responsive variants from your media pipeline/CMS. Cap hero images; compress thumbnails; avoid oversized background images. Audit with a crawler/Lighthouse for “properly sized images” issues.
  • Check Google Search Console (Mobile Signals)
    Technical SEO checklist-0092 Search console errors Review Core Web Vitals (mobile) and Page indexing. Use URL Inspection (smartphone crawler) to see rendered HTML/screenshots, blocked resources, and mobile parity issues. Fix discovered problems and request re-crawl where needed.

  • Ensure Favicon Displays in Mobile SERPs
    Technical SEO checklist-0098 Is the Favicon being displayed in mobile SERPs? Provide a square favicon (multiple sizes, at least 48×48) via . Use a high-contrast design; host on the same domain and keep it crawlable. Verify in live results and update caches when rebranding.
  • Ensure Parity: Content, Meta & Directives Match Desktop
    Technical SEO checklist-0099 Parity checks - Content, Meta & Directives the same as desktop? Mobile-first indexing uses your mobile version. Keep the same primary content, internal links, structured data, meta robots, canonical/hreflang, and robots.txt access on mobile and desktop. Avoid hiding critical copy or links on mobile.
  • Test on Real Devices (Pre-/Post-Release)
    Technical SEO checklist-0100 Mobile Testing Run Lighthouse (mobile), field data checks, and device labs. Validate templates after releases, especially nav, forms, and media. Track mobile Core Web Vitals, crash/JS error logs, and regressions; ship fixes behind flags and re-test before full rollout.

💨 Speed

  • Load Content Fast (Prioritize Above-the-Fold)
    Technical SEO checklist-0101 Content fully loads within a reasonable timeAim for fast first view: ship only critical HTML/CSS/JS for above-the-fold, defer the rest. Preload the hero image/font, minimize render-blocking CSS/JS, code-split, and cache via CDN/HTTP/2/3. Reduce server TTFB with caching and efficient queries. Track LCP element, total JS execution time, and image weights per template.
  • Pass Core Web Vitals (Field Data)
    Technical SEO checklist-0102 URL passes Google's Core Web Vitals assessmentA URL (or origin) passes when the 75th percentile (mobile, then desktop) of all three metrics is “Good”: LCP ≤ 2.5s, CLS ≤ 0.1, INP ≤ 200 ms. Check in Search Console → Core Web Vitals and PageSpeed Insights (Field Data). Fix the bottleneck metric first (e.g., LCP image size/priority, layout shifts, input delay from heavy JS).
  • Fix Common Speed Traps
    Technical SEO checklist-0103 Address common speed trapsEliminate: oversized images/video, render-blocking CSS/JS, unused JS/CSS, excessive third-party tags, large DOM trees, webfont FOIT/FOUT, chat widgets loading on every page, client-side rendering without streaming/SSR, missing caching/compression, and unoptimized hero images. Lazy-load below-the-fold media; preconnect/preload critical origins/resources.
  • Run a Comprehensive Speed Audit
    Technical SEO checklist-0104 General website speed checkTest templates on throttled mobile. Use PageSpeed Insights (field + lab), Lighthouse, and WebPageTest (filmstrip/CPU). Compare field vs. lab gaps, group issues by template, and create an optimization backlog. Add performance budgets to CI, monitor regressions, and re-test after releases.
  • Check Core Web Vitals (Desktop) in Search Console
    Technical SEO checklist-0105 Desktop website Speed Checks in the Search Console In Search Console → Core Web Vitals (Desktop), review failing URL groups and the example URLs. Follow the “Learn more” diagnostics to PageSpeed Insights, fix by template (e.g., LCP images, CLS from ads/carousels), deploy, and Validate Fix to reprocess groups.
  • Check Core Web Vitals (Mobile) in Search Console
    Technical SEO checklist-0106 Mobile website Speed Checks in the Search Console Mobile data is the priority for ranking. Inspect Core Web Vitals (Mobile) groups, open examples in PSI, and focus on mobile LCP (image priority/size), CLS (reserve space; avoid late-loading banners), and INP (trim JS, split bundles, defer non-critical listeners). Validate fixes after rollout.
  • Meet Core Web Vitals Thresholds
    Speed SEO checklist - Core Web Vitals thresholds?Target LCP ≤ 2.5s, CLS ≤ 0.1, INP ≤ 200 ms at the 75th percentile (mobile-first). Use CrUX/GA4 for field data where available. Improve LCP by optimizing the hero image, server TTFB, and resource priority; prevent CLS with fixed dimensions/placeholders; reduce INP by cutting long tasks, scheduling work off the main thread, and deferring non-essential JS.

🔒 Security

  • Run Malware & Security Checks
    Technical SEO checklist-0107 Malware & Security ChecksScan regularly for hacked content and malware (GSC Security issues, Safe Browsing, server/WAF scans). Patch CMS, plugins, themes; enforce 2FA for admins; use least-privilege access; keep daily offsite backups. Monitor file integrity and server logs; set alerts for unusual spikes, new admin users, or outbound spam.
  • Enable HSTS (HTTP Strict Transport Security)
    Technical SEO checklist-0108 Is an HSTS policy in place?Force browsers to use HTTPS with the header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload Only enable after all traffic works on HTTPS and HTTP→HTTPS 301s are in place (including subdomains). Consider HSTS preload once confident; don’t set on staging. HSTS helps prevent protocol downgrade and cookie hijacking.
  • Ensure No Hacked Content or Malware
    Technical SEO checklist-0109 No hacked content, malware, or other security issues Check GSC Security issues, server AV/WAF reports, and error logs. Remove injected code/links, update credentials, and patch the entry point (plugin/theme/core). Request Review in GSC after cleanup. Add a WAF/CDN, rate limiting, and bot rules to reduce future risk.
  • Force HTTPS Across the Site (Single Canonical Protocol)
    Technical SEO checklist-0110 Using the main protocol on all website pages (HTTP / HTTPS)?Serve one protocol: 301 all http:// to https:// (and enforce one host, e.g., www or root). Fix mixed content (upgrade assets to HTTPS), update canonicals, hreflang, sitemaps, and internal links to HTTPS. Pair with HSTS and secure cookies (Secure, HttpOnly, SameSite).
  • Maintain a Valid TLS Certificate (HTTPS)
    Technical SEO checklist-0111 Does the website have a valid SSL certificate?Use a trusted CA (e.g., Let’s Encrypt) with auto-renewal and the correct chain. Enable modern TLS versions, OCSP stapling, and strong ciphers. Verify the certificate matches all hostnames (SANs) and that renewal doesn’t break redirects. Test with an SSL/TLS checker; fix warnings promptly.
  • Make Cookie Banners Lightweight (No CLS)
    Security/UX checklist - cookie banner CLS?Keep consent banners small, accessible, and non-blocking. Reserve space to avoid CLS, provide clear choices (accept/reject/customize), and trap focus correctly for keyboard users. Delay non-essential scripts until consent; store preferences and avoid re-prompt spam.
  • Harden Security Headers (CSP, Permissions-Policy, Referrer-Policy)
    Harden Security Headers (CSP, Permissions-Policy, Referrer-Policy)Ship X-Content-Type-Options=nosniff, Referrer-Policy=strict-origin-when-cross-origin, Permissions-Policy to limit sensors (camera/mic/geo), and a CSP with allowlists (and/or frame-ancestors for embedding control). Verify on securityheaders.com, Mozilla Observatory, and Chrome DevTools → Network/Headers.

🌍 International & Multilingual Sites

  • Configure Geo-Targeting Signals
    Shopify Launch Checklist-0113 Signal location targetingUse clear geo signals: ccTLDs (e.g., .de) or locale subfolders (/de/, /fr-fr/), consistent local currency/phone/address, local contact pages, and language selectors. Pair with correct hreflang and avoid relying on server location. Keep one canonical per locale and link between alternates.
  • Implement Valid hreflang (With Return Tags)
    Technical SEO checklist-0114 Valid hreflang annotationAdd reciprocal hreflang for each language/region pair using ISO codes (e.g., en-gb, fr-fr) plus a self-referencing tag. Use x-default for the global/selector page. Place tags in HTML or XML sitemaps—be consistent with canonicals (only indexable canonicals should be referenced). Fix common errors: wrong codes, missing returns, mixing HTTP/HTTPS, pointing to non-200 pages.
  • Make Page Language Obvious
    Technical SEO checklist-0115 Page language is obvious Set the HTML lang attribute (e.g., <html lang="uk">), keep copy in a single language per URL, and match UI elements (navigation, forms). Use localized dates, units, and currency. Avoid auto-translating on the fly without giving users a stable, linkable localized URL.
  • Avoid Forced Geo/Language Redirects
    Technical SEO checklist-0116 Avoid automatic redirection Don’t auto-redirect users (or crawlers) by IP/Accept-Language to another locale; it breaks discovery and annoys travelers/expats. Instead, show a non-blocking locale banner and remember user choice. If redirects are absolutely required, never redirect Googlebot, keep alternate links, and allow manual switching.
  • Define International Audiences and Markets
    Technical SEO checklist-0117 Does the website have an international audience? List target countries/languages, search behavior, and SERP competitors. Prioritize markets by demand and resources, then map pages/sections to each locale. Align keywords, pricing, shipping, and support to each market before rolling out URLs and hreflang.
  • Provide High-Quality, Human-Reviewed Translations
    Technical SEO checklist-0118 Is the website being translated without errors?Use professional translation or expert review—don’t ship raw machine output. Localize terminology, CTAs, legal text, images/screenshots, and schema (e.g., inLanguage). Check slugs, alt text, and metadata. QA for placeholders, broken characters, and layout overflow in long languages.
  • Use a Clear International URL Structure
    Technical SEO checklist-0119 Is the website using an international URL structure?Choose one model per market: ccTLD (example.de), subdomain (de.example.com), or subfolder (example.com/de/). Prefer subfolders for easier consolidation unless strong geo signals (ccTLD) are required. Keep structure mirrored across locales and avoid mixing patterns.
  • Serve the Correct Localized Page
    Technical SEO checklist-0120 Are the correct localized web pages being used?Ensure each locale page links to its alternates via hreflang and that internal links stay within the locale (e.g., /fr/ → /fr/). Preserve user-chosen locale across sessions. Use x-default for the selector and provide visible language/country switchers.
  • Earn Local Backlinks in Target Markets
    Technical SEO checklist-0121 Does the website have backlinks from target countries?Pursue links from relevant sites in each country/language (local media, associations, universities, partners). Local TLDs and same-language context strengthen geo relevance. Create locale-specific assets (data, guides, events) that deserve local coverage.
  • Clarify Site Type: Multilingual, Multiregional, or Both
    Technical SEO checklist-0122 Is the website Multilingual, Multiregional or both?Multilingual targets multiple languages; multiregional targets different countries/regions. Many sites are both (e.g., en-us, en-gb, fr-fr). Reflect this in URL structure, hreflang, content, pricing, and legal info. Document rules for when to split by language vs. by region and keep them consistent across templates.

🧱 Website Architecture

  • Check Pagination
    Technical SEO checklist-0137 Pagination checksGoogle doesn’t use rel="next/prev" anymore. Keep page 1 and page 2+ as separate, indexable URLs with self-canonical (don’t canonical all to page 1). Use HTML links (Prev/Next and numbered lists), unique titles (e.g., “Page 2”), and expose URL pages for infinite scroll via href/History API (e.g., ?page=2). Avoid noindex on deeper pages if they carry unique items.
  • Use Short, Descriptive URLs
    Technical SEO checklist-0138 Use short URLs Keep slugs short, lowercase, hyphen-separated, and meaningful. Avoid IDs, dates, stop-word clutter, file extensions, and tracking params. Be consistent with trailing slash and prefer a single, stable path per page.

  • Provide a Correct robots.txt
    Technical SEO checklist-0142 Robots.txt present?Use robots.txt to manage crawl, not indexing or security. Disallowed URLs can still be indexed if linked. To exclude pages, use noindex (meta/X-Robots-Tag) or auth. Include Sitemap: lines and don’t block essential CSS/JS.
  • Block Crawl Strategically with robots.txt
    Technical SEO checklist-0143 Are pages being correctly blocked by Robots.txt?Block low-value crawl paths (e.g., infinite filters, session/search pages), but don’t rely on robots.txt to hide content—it doesn’t prevent indexing. For sensitive/private pages, require auth or apply noindex and remove from sitemaps.
  • Design Clear Topic Hubs (Silos)
    Technical SEO checklist-0144 Site Structure & Silo UseGroup content into topic hubs with hub → subpage linking, breadcrumbs, and related links. Keep paths shallow, avoid duplicate paths to the same content, and ensure each hub targets a distinct intent/keyword set.

  • Provide Helpful 404 Pages
    Technical SEO checklist-0147 Error Pages 404Serve a custom 404 with search, popular links, and paths back to hubs. Fix internal links causing 404s; use 410 for permanently removed content; redirect only when a clear equivalent exists. Exclude 404s from sitemaps.
  • Use Tag Pages Strategically
    Technical SEO checklist-0148 Are Tag Pages being used?Avoid thin, duplicate tag archives. Default to noindex unless a tag page is curated with unique copy and strong internal demand. Prevent tag/category duplication and keep pagination clean with self-canonicals.
  • Implement Breadcrumbs (UI + Schema)
    Technical SEO checklist-0149 Is the website using a Breadcrumb trail?Add breadcrumbs in templates and mark up with BreadcrumbList schema. Keep anchors descriptive and ensure trails reflect the real hierarchy (don’t invent paths). Link breadcrumbs sitewide to improve crawl and context.
  • Simplify Primary Navigation
    Technical SEO checklist-0150 Is primary navigation easy to use?Limit top-level items, prioritize key hubs, and use crawlable HTML links (not JS-only). Make it keyboard-accessible, consistent across desktop/mobile, and avoid mega-menus that dump hundreds of links on every page.
  • Optimize Footer Navigation
    Technical SEO checklist-0151 Footer navigation checks?Use the footer for utility and trust (About, Contact, Policies, Key categories). Avoid link farms or keyword-stuffed lists. Keep anchors consistent and ensure links point to canonical URLs.

    Technical SEO checklist-0152 Menu setup and useKeep header/mobile menus aligned, expose essential links without deep nesting, and maintain a persistent mobile menu. Ensure LCP elements aren’t blocked by heavy menu JS and that menu links are indexable anchors.
  • Strengthen Internal Links and Remove Orphans
    Architecture checklist - internal linking & orphan pages?Identify and fix orphan pages (add links from hubs, nav, or relevant articles). Use descriptive anchor text, surface money pages from category hubs, and keep priority pages within ≤3 clicks. Keep sitemaps in sync with canonical URLs.
  • Control Faceted Navigation (E-commerce)
    Architecture checklist - faceted navigation?

    Pick one clean indexable path (category) and prevent combinatorial crawl.

    • Index only valuable facets (e.g., /shoes/black/), each with self-canonical and unique content.
    • Disallow infinite combos via robots patterns and nofollow UI where needed; avoid blocking essential CSS/JS.
    • Provide static links to top facets; keep sort/order params non-indexable.
  • Handle Out-of-Stock/Discontinued Products (301/410 + UX)
    Handle Out-of-Stock/Discontinued Products (301/410 + UX)Temporarily OOS: keep indexable, show alternatives, set Product schema availability=OutOfStock. Permanently discontinued: 301 to the closest relevant product/category; if none, 410 and remove from sitemaps. Preserve reviews/specs on successor SKUs. Check GSC Page Indexing, Rich Results Test, and crawler for soft-404s.

⚙️ Technical SEO Checks

📷 Images/Video

  • Audit Sitewide Image Usage
    Technical SEO checklist-0171 How many images are used sitewide?Too many images can slow down the page, leading to poor user experience and lower ranking. Measure image count and total bytes by template (home, PLP, PDP, blog). Remove decorative bloat, compress aggressively, and avoid image-heavy carousels. Prioritize content images that support the task and LCP. Track image bytes and LCP in field data; cut or replace non-essential assets.
  • Optimize Images
    Technical SEO checklist-0172 Are images being optimized? Serve modern formats (AVIF/WebP with fallbacks), compress to perceptual quality, and export at the exact display dimensions. Add width/height (or intrinsic size) to prevent CLS, lazy-load below-the-fold, and use fetchpriority="high"/preload for the hero image. Verify with Lighthouse/PageSpeed and CrUX.
  • Provide Meaningful Alt Text
