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.
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)
