Axeptio vs Cookiebot vs Didomi: Which CMP Should You Choose?

Choosing a CMP Is Not a Trivial Decision

The Consent Management Platform you choose directly impacts two critical metrics: your consent acceptance rate (and therefore the volume of usable data) and your regulatory compliance. A poor choice can cost you 30% of your analytics data or expose you to fines. Here is a detailed analysis of the three dominant players in the European market to inform your Consent Mode and CMP strategy.

Banner UX: The Acceptance Rate Battle

Axeptio stands out with a playful and customizable design. Its widget-style banner with engaging visuals achieves some of the highest acceptance rates on the market (75-85% depending on the integration). The UX approach is a genuine differentiator.

Cookiebot offers a more classic banner, configurable but less visually distinctive. Acceptance rates range between 65 and 75%. Cookiebot’s strength lies in its automatic cookie scanner that detects and categorizes trackers present on your site.

Didomi provides the highest level of customization with an advanced visual editor and the ability to A/B test the consent banner. This feature allows you to scientifically optimize the acceptance rate — a significant advantage for high-traffic websites.

GTM Integration and Consent Mode v2

All three platforms support Google’s Consent Mode v2, but with different levels of maturity:

• Didomi: native and well-documented integration, support for Advanced Consent Mode with cookieless pings. Actively maintained official GTM template.
• Cookiebot: widely used Community GTM template, solid documentation. The transition to Consent Mode v2 was fast and well supported.
• Axeptio: full Consent Mode v2 support, but GTM integration sometimes requires manual adjustments for complex configurations.

Pricing: Very Different Models

Axeptio charges per domain and session volume: free up to 300 sessions/month, then starting at 19 euros/month. Simple and predictable model.

Cookiebot charges by number of scanned pages: free for 1 domain and 50 pages, then from 14 euros/month. Be careful — sites with many pages (e-commerce, media) can see the bill climb.

Didomi does not publish its pricing. The positioning is enterprise, with annual contracts typically starting at 500 euros/month. The investment is justified by advanced features (A/B testing, consent analytics, multi-regulation support).

GDPR Compliance and European Specifics

All three CMPs comply with GDPR recommendations. However, some nuances exist:

• Axeptio (French company, servers in France) offers the best sovereignty guarantees.
• Cookiebot (Usercentrics, Germany) hosts data in Europe with a solid DPA.
• Didomi (French company) combines sovereignty with multi-regulation capability (GDPR, CCPA, LGPD).

Decision Matrix

Choose Axeptio if acceptance rate is your priority and your budget is limited. Choose Cookiebot if you need an automatic cookie scanner and quick setup. Choose Didomi if you are a large enterprise with multi-country requirements, want to optimize consent through A/B testing, and have the budget for an enterprise solution. In all cases, verify compatibility with your GTM stack and tags before committing.
