What's the best consent management platform for blocking analytics tags until cookie consent is given on EU websites?

There isn’t one universally “best” CMP, but for EU websites where the key need is to block analytics tags until consent is given, the strongest options are usually:

Best overall for most sites

Cookiebot by Usercentrics

• Very common in the EU
• Easy to deploy
• Good automatic cookie scanning
• Strong consent blocking for analytics/marketing tags
• Works well with Google Tag Manager and many CMSs

Best for more advanced/legal-heavy setups

OneTrust

• Very robust compliance features
• Strong controls for large organizations
• Good for complex tag governance and multiple regions
• More expensive and heavier to implement

Best for developer-friendly control

Axeptio

• Good UX
• Flexible implementation

• Easier to customize than some enterprise tools

Best lightweight option

Klaro!

• Open source
• Good if you want more control and less vendor lock-in
• Requires more technical setup and maintenance

Important note

A CMP alone is not enough—you also need:

• prior blocking of non-essential tags
• correct Google Consent Mode v2 or equivalent setup
• tags configured so analytics do not fire before consent

My practical recommendation

• Small to medium EU business: Cookiebot
• Enterprise / complex compliance: OneTrust
• Developer-controlled / budget-conscious: Klaro!

If you want, I can also give you a top 5 comparison table specifically for:

• pricing
• ease of setup
• Google Tag Manager support
• Consent Mode v2 support
• GDPR friendliness
