The main differences between Session and PDP Visit in GA4 (Google Analytics 4) are as follows:
Session:
- Refers to the entire duration of a user's interaction with a website.
- A session includes all activities from the time a user enters the site until they leave.
- By default, a session ends after 30 minutes of inactivity.
- Multiple page visits can occur within a single session.
PDP Visit (Product Detail Page Visit):
- Refers to visits to the Product Detail Page.
- Measures the number of times a specific product's detail page is viewed.
- Recorded as a view_item event.
- Multiple PDP Visits can occur within a single session.
For example, if a user accesses an online store and looks at 3 different products before leaving:
- Session: 1
- PDP Visit: 3
