Checking for Optimization Errors
The first function of the Plerdy extension is a quick search engine SEO on-page audit. During an SEO check of websites, it analyzes the following parameters:


Knowledge is power. Upgrade your site to the World's Strongest category.

Internal Links Checking
The SEO check website extension allows you to analyze the anchor text of an internal link, detect sub-optimal naming, and switch to more relevant variants. It also analyzes the number of duplicate internal links. Internal links are important because Google’s algorithms pay attention to them. Relevant anchor text helps to understand whether the webpage is helpful. It also marks related topics and gives a chance to achieve higher-ranking positions.


External Links Checking
External links connect other domains with links on your owned pages. Pay attention to using this function of an SEO check website extension. External links are even more important for rising the ranks in search engines to top positions as they show how many and which links go out from examined pages. Another important factor is the ability of search engines to follow an external link. You can see DoFollow and NoFollow statuses in our report.
SEO Text Analysis
Analyzing text semantics with the Plerdy Chrome extension has never been easier. Explore the site's text content effortlessly without wasting time. In one click, an SEO plugin Chrome extension provides you with a statistical report on the most important metrics:

Keyword Analysis
Keywords are one of the 200 search engine ranking factors. Marketing specialists cannot do without this investigation. The SEO test Chrome extension will list keyword groups that are automatically aggregated based on the following categories.
- support, supported, supports
- sell, selling
- brand, branding
When you click on a keyword, each word will be highlighted in a unique color, making it easier to analyze them across the page.
Stop Word Analysis
A great feature of the analyzer Chrome extension is this tool, which determines the noise word bindings of the checked text. Use this data to improve articles on your site. Be strict and remove all unnecessary synonyms and unclear additions to keep published texts in great shape.

Image Analysis
Images play a significant role when it comes to web page ranking. Therefore, they should have an appropriate figuration to improve your articles’ positions. The Plerdy Chrome extension checks the number of ALT tags for each sample. It highlights images with missing attributes. As far as it allows adding a text description to the image, it can include keywords as other parts of the text. Algorithms of Google Chrome and other search engines also consider this parameter.
Open Graph

Algorithms check the following parameters:
- Object’s title that appears within the graph
- Similar to meta description, a short page explanation
- A canonical object URL or its permanent ID
- A necessary specification that defines the object type
- An URL that presents objects within the graph
