What this does not prove

FAQ
Does TrackCanary access my GTM account?
No. TrackCanary scans visible public website signals only. It does not access GTM account data, workspaces, triggers, tags, or variables.
Can this prove the GTM container is configured correctly?
No. A visible GTM signal only means GTM appears to load where the scan can detect it. Container configuration should still be reviewed manually.
What should I check after GTM is visible?
Review whether forms, buttons, calls, WhatsApp clicks, and commerce paths have the right triggers and events in GTM Preview and platform debugging tools.
