Which CMP should you choose for your website?

Essential selection criteria

A CMP (Consent Management Platform) handles the collection and storage of visitor consent for cookies and trackers. Your CMP choice should be based on several objective criteria: compatibility with Google’s Consent Mode v2, compliance with GDPR requirements, ease of integration with your tech stack (GTM, CMS), banner customization, and of course cost.

Consent Mode v2 compatibility has become a blocking criterion if you use Google Ads. Google maintains an official list of certified CMPs (CMP Partners). Verify that your solution is listed before any commitment. Beyond certification, test the quality of the integration: some CMPs transmit consent signals with a delay that causes data loss.

Leading solutions on the market

Axeptio is a French solution with a particularly polished user interface and an excellent acceptance rate. It offers a limited free plan and affordable packages for SMBs. Cookiebot (Usercentrics) provides automatic cookie detection and solid technical documentation. Free up to 50 pages. Didomi targets enterprise accounts with advanced preference center features and multi-channel support. Tarteaucitron is a French open-source solution, free, but requires more technical skills for integration and maintenance.

Recommendations based on your profile

For a brochure site or small e-commerce store, Axeptio or Cookiebot offer the best simplicity-to-compliance ratio. For high-traffic sites with complex advertising needs, Didomi or OneTrust are better suited. In all cases, the CMP must be configured to effectively block scripts before consent, not simply display a cosmetic banner. A banner that blocks nothing exposes you to regulatory fines that can reach several percent of revenue.
