CMP setup agency, GDPR-compliant without tanking conversion.
A specialised agency for installing and tuning Consent Management Platforms. We deploy Didomi, OneTrust, Cookiebot, Axeptio or a headless setup to keep you compliant with GDPR, ePrivacy and CNIL guidance, while preserving analytics, attribution and ad performance.
Why pick a specialised CMP agency
Most CMP projects fail on two fronts: compliance is shaky, or opt-in rates collapse. We fix both.
Compliant by design
Prior consent, granular purposes, clear rejection, audit log. CNIL and EDPB guidelines baked into the configuration.
Higher opt-in rates
A/B-tested banner copy, layout and language switching. Most clients see 15 to 30 % more consent after our rework.
Analytics stay alive
Consent Mode v2 and server-side hooks so GA4, Ads and Meta keep modelling conversions even when users refuse.
One integration, every stack
GTM, server-side GTM, Shopify, WordPress, Next.js, plain PHP. We ship the right snippet for your setup.
Readable reports
A monthly PDF for your DPO with opt-in rate, vendor list drift and policy changes. No jargon.
Not a black box
You own the config, the banner copy, the vendor list. We hand it over with the runbook.
Our 4-step CMP setup method
We handle the plumbing. You get compliance, clarity and tracking that still works.
Audit
We crawl your site, inventory cookies and vendors, check your current banner against GDPR and CNIL guidance. You get a report.
Design
We pick the right CMP for your stack, write banner copy that maximises opt-in, and map each vendor to a purpose.

Frequently asked
Q·01 Which CMP do you recommend?
It depends on your stack, budget, and geographies. For EU-focused businesses we often suggest Didomi or Axeptio; for global/IAB-TCF workflows, OneTrust or Didomi; for small WordPress sites, Cookiebot or Complianz. We are not reseller-locked.
Q·02 Will this hurt my analytics?
Short answer: no, if done right. We wire Google Consent Mode v2 plus a server-side layer, so GA4 and Google Ads keep modelling unconsented conversions within legal limits. Typically you recover 60 to 80 % of the data you'd otherwise lose.
Q·03 Do you handle both GDPR and the CNIL guidance?
Yes. The CNIL has stricter specifics than generic GDPR: equal prominence of "Accept" and "Reject", no consent walls, pre-ticked boxes banned, etc. Our defaults are CNIL-aligned.
Q·04 How long does a setup take?
Two weeks on average from kick-off to go-live for a standard setup. Complex stacks with server-side tracking or custom vendors can take 3 to 5 weeks.
Q·05 Can you work with our existing GTM or CMP?
Yes. Audits and optimisations on an existing install are common. We don't force a migration unless there's a real reason.
Q·06 Do you offer ongoing support?
Yes. The "Care" plan covers monthly reviews of vendor drift and regulator updates. Most clients stay on it because cookie rules change constantly.
