Google Analytics tracks all of the listed options: pageviews, events, and transactions.
Google Analytics Help states that a hit is an interaction that triggers data transmission to Analytics. Each time user behavior activates the embedded code (for example, a user loads the website page), Analytics records this interaction. After that, the action is packaged into a hit and transmitted to Google’s servers for record-keeping.
Overall, there are the following common hit types. Apart from these hits, you can combine various parameters to customize website tracking (for example, see on which page an event occurred).
Hit types with examples:
- Page tracking. A hit is recorded every time a user views a web page, even if they have been on this page before.
- Event tracking. A hit is recorded every time a user interacts with a web page (e.g., clicks a link, replays a video, submits a form, downloads content, etc.).
- Ecommerce tracking. A hit is recorded every time a user interacts with an e-commerce page (e.g., adds a product to their cart).
- Social interaction hits. A hit is recorded every time a user completes a social interaction on a specific web page (e.g., clicks a social share button)
