We recommend analyzing data through the session_start event and Page Location dimension.
You can identify the landing page that led to that page through the Session_start event that fires when a specific session starts and the Page Location dimension.
We recommend that you check the data by setting the conditions as follows.
[Report Conditions]
- Rows : Event Name, Page Location
- Values : Sessions
- Culumn : Session Default Channel Group (Not required)
- Filters : Event Name exactly matches session_start
* You can check with Landing page + query string and full_url_for_landing_page, but as it needs to be modified to improve consistency, please use Page Location for page analysis.
