Google are transitioning Analytics users to GA4, which has a different type of reporting. Previously it was very easy to see a list of referrers with their full URL. In GA4 it doesn’t seem possible, but I found a reasonable workaround.
Use the Explore tab to create a new Exploration with the following settings:
- Dimensions: Page referrer
- Metrics: Active users
- rows: Page referrer
- show rows: 500 (optional)
- values: Active users (or New users)
- cell type: Heat map (optional)
- filters: (exclude any URL patterns here)
Then minimise the Variables and Settings panels.
This will give you a long table of full referrer URLs along with the number of users that came from there. In my case most are domain names, but a handful are full URLs pointing to a page.
It remains to be seen if this can be done more easily or more comprehensively.
