What can you do to remove this unwanted referral traffic?
Within the GA4 dashboard you can build a set of conditions that identify the websites whose traffic you don’t want to recognize as referrals in order to exclude the referrals and ensure that your data only includes referrals in which you’re interested.
In Google Analytics 4 (GA4), you may stop referral data from being included in your reports by adding domains to your “Unwanted Referrals” list.
Here’s how to add domains to your “Unwanted Referrals” list:
In Admin, under Data Collection and Modification, click Data streams.
Click Web and then click a web data stream.
In the web stream details, click Configure tag settings (at the bottom).
In the Settings section, click Show all to see all available settings.
Click List unwanted referrals.
Add the domain URL you wish to block
Click Save.
You have now blocked the unwanted referral traffic from your GA4 Analytics data.
