What we check
Looks for server-side tagging indicators: stape.io, sGTM endpoints, first-party subdomains.
Why it matters
Server-side tagging bypasses ad blockers, stabilises attribution, and decouples tracking from the frontend.
Common causes
- There simply is no server-side setup, all tags send straight from the browser to the vendor domains.
- The server container exists, but the web container still sends to the standard endpoints instead of the first-party subdomain.
- The setup runs on a subdomain the scan does not recognise as a tagging endpoint, then check your own request targets.
- An sGTM project was started and never finished, the container idles along.
