What is a CMP?

A CMP (Consent Management Platform) collects and documents user consent for cookies and data processing. In the Google ecosystem, integration with Consent Mode v2 is key - without correct consent signals GA4 and Google Ads lose conversion data. Choose a CMP by scale (SMB vs enterprise), TCF 2.2, jurisdiction and stack (GTM, CMS, analytics).

CMP and Consent Mode v2

Consent Mode v2 requires correct CMP + GTM setup - a GDPR banner alone is not enough. Cookiebot and Usercentrics are a fast path for SMB with Google CMP Partner certification. OneTrust and Didomi dominate enterprise and programmatic (TCF 2.2). iubenda combines legal documents with a banner; Cookie Information is a Danish Google CMP Gold Partner for the EU.

Minimum CMP implementation plan (7 steps)

  1. Inventory cookies and tags (GTM, third-party scripts).
  2. Choose CMP by scale, jurisdiction and budget.
  3. Configure banner, consent categories and legal texts.
  4. Integrate with GTM - CMP template and Consent Mode v2 (default + update).
  5. Test consent signals in Tag Assistant and GA4 DebugView.
  6. Enable TCF 2.2 if you run programmatic advertising.
  7. Monitor consent rate, GA4 data quality and vendor updates.

FAQ

How is a CMP different from a simple cookie banner?

A CMP is a platform with scanning, consent records and integrations (GTM, TCF). A simple banner without CMP often fails audit and Consent Mode requirements.

Cookiebot or Usercentrics?

Both are Google CMP partners and good for SMB/mid-market. Cookiebot - more popular globally; Usercentrics - stronger in DACH and EU enterprise.

When OneTrust or Didomi?

For enterprise, multiple domains, TCF 2.2 and programmatic ads. Cost and implementation are much higher than SMB CMP.

How much does a CMP cost?

From €0 (Cookiebot up to 50 subpages, CookieYes up to ~25k PV) through €4-10/mo (iubenda, Cookiebot Premium) to several hundred+ EUR/USD/mo (enterprise).

Does a CMP solve GDPR?

A CMP supports consent collection and documentation but does not replace legal basis, privacy policy or processor agreements.

What is Consent Mode v2?

Google mechanism passing consent signals to GA4 and Ads. Requires correct CMP + GTM integration - critical for remarketing in EEA since March 2024.

iubenda or dedicated CMP?

iubenda - when you need legal documents + banner in one package. Dedicated CMP (Cookiebot, Didomi) - when ad-tech and Consent Mode are priorities.

What's the most common mistake?

Deploying a banner without Consent Mode v2 in GTM - users see consent UI but Google tags still behave as before GDPR.
