Consent Mode / tracking-breakage checker
Scan a page for GTM, gtag, Meta pixel, CMP, Consent Mode v2 parameters and server-side tagging hints — before ads and GA4 go dark.
Frequently asked questions
Google’s API that tells tags whether ads and analytics storage are granted. v2 adds ad_user_data and ad_personalization, required for EU advertising features.
No. A pixel that fires before consent, or without v2 params, can be illegal and still lose modeled conversions.
We read the HTML we fetch. Server-side GTM on another host may not appear — that’s flagged as a hint, not a proof.
