sGTM
Checking…
Why sGTM is partially blocked: This setup serves the container from a first-party subdomain (brand.fulcos.com), so the container script loads successfully. However, it uses the default gtm.js filename, which ad blockers pattern-match. The GA4 library loaded by the container also gets blocked. To fully bypass script-level blocking, you need obfuscated script paths — which is what Addingwell adds on top of sGTM. Both use the same server-side container (GTM-T3X85M) at brand.fulcos.com.
