Recognised Search Engine Domains

When a visitor arrives on your site from one of these domains (without paid UTM parameters), they’re categorised as Organic Search.

Subdomains are matched automatically. For example, google.com in the list also matches www.google.com, search.google.com, and any other subdomain.

This list is maintained by SourceTag and updated regularly. You can extend it per site by adding extra domains to the Organic Search channel in your channel settings.
