CMP Verification

CookieFirst Compliance Checker Verify Your Setup Is Working

CookieFirst is a Google-certified consent management platform that focuses on native Google Consent Mode integration. But certification covers the CMP's own signal handling - third-party scripts, tag manager rules, and analytics pixels on your site can still fire outside CookieFirst's control, silently, with no warning from the dashboard.

We work alongside CookieFirst - not against it

CookieFirst manages your consent configuration and Google Consent Mode integration. We independently verify that configuration produces the right outcome in a real browser - catching issues that CookieFirst cannot see from inside the page.

What we verify that CookieFirst alone cannot confirm

CookieFirst controls what it controls. These six checks require independent observation from outside the page.

CheckWhy CookieFirst alone cannot confirm it
Pre-consent cookiesCookieFirst manages consent and integrates with Google Consent Mode - but third-party scripts, analytics pixels, and marketing tags loaded outside its control can fire before consent is granted.
Google Consent Mode v2 signalsCookieFirst is a Google-certified CMP with native Consent Mode support, but signal timing and the presence of all 4 v2 signals (ad_user_data, ad_personalization) must be verified from outside the page.
Reject All enforcementA site update, new marketing integration, or tag manager deployment can add scripts that fire regardless of the consent state CookieFirst tracks - with no alert from the CookieFirst dashboard.
GPC signal handlingGlobal Privacy Control requires a browser-level test. CookieFirst can be configured to honor GPC signals - but configuration alone does not confirm it works in a live browser session.
Dark pattern checksCookieFirst provides the consent widget framework and styling options. The choices made during setup - button prominence, pre-selected categories, dismiss behavior - are outside CookieFirst's enforcement.
Multi-region behavior (up to 15 regions)CookieFirst supports geo-targeted consent rules for GDPR, CCPA, and other frameworks. We test from actual jurisdiction IPs to verify that region-specific consent flows activate correctly.
