WebIntel.site Maps Shared Tracking Infrastructure

Field notes

The interface supports searches by either a domain or a tracking identifier, then describes the reverse relationship between them: domains reveal associated IDs, while IDs reveal other domains using the same value. Coverage is divided by identifier family, with GTM, Google Ads, and older Universal Analytics IDs marked as higher-value correlation signals than GA4 IDs. The page explicitly cautions that shared infrastructure does not establish common ownership, an important limitation for investigative use.
