GA4 referral exclusion list generator
Pick the login providers and payment processors your site uses, add your own domain, and get a ready-to-paste list for GA4’s referral exclusion setting. It stops those redirect hops from breaking your attribution and inflating direct traffic. No login, nothing stored.
Your own domain (self-referral)
Sessions can split when visitors move between your own domains or subdomains, for example a checkout on a different subdomain. Add each one, no www, no https.
Login / SSO providers you use
A login redirect hop registers as a referral in GA4 and starts a new session credited to the login provider instead of the original source.
Payment processors you use
Returning from a hosted checkout page starts a new session credited to the payment gateway instead of the campaign that drove the purchase.
Your exclusion list
Select what you use above and your list appears here.
Add each domain in GA4 as its own entry: Admin → Data Streams → Configure tag settings → List unwanted referrals → Add condition → Domain contains [value].
This list covers redirect hops. A full audit checks this alongside consent, tag governance, and conversion accuracy, scored A–F. Your first audit is free.

Referral exclusions are one fix among several for traffic showing up in the wrong channel. See the unassigned traffic guide for the other causes, and the conversion tracking audit for how it affects checkout data specifically. More symptoms are indexed at Fix GA4.
FAQs
What does a referral exclusion do in GA4?
It tells GA4 not to treat a redirect through that domain as a new traffic source. Without it, returning from a login page or a hosted checkout starts a new session credited to the login or payment provider instead of the campaign that brought the visitor in the first place.
Where do I add these in GA4?
Admin, then Data Streams, then your web stream, then Configure tag settings, then List unwanted referrals. Add each domain from the list as its own condition, Domain contains [value].
Why isn't email or social on this list?
Referral exclusion only fixes redirect hops, sessions that leave your site and come straight back, like a login or checkout. Email, social and CRM links arrive as referral for a different reason, the link itself was never tagged, so the fix there is adding UTM parameters, not an exclusion.
