The banner decides how much of your campaigns you can see
With Consent Mode v2, what the user answers in the banner determines which signals reach Google Ads, GA4 and the rest of your platforms. A banner that fails to record consent properly, a tag that fires too early or a badly configured advanced mode all turn into conversions that go unattributed, audiences that never fill up and bidding that optimises on incomplete data.
The usual fix — 'make the banner more aggressive' — is exactly what the AEPD considers contrary to its cookie guidance. The good news is that complying properly and measuring properly don't compete: clean consent, with tags that are genuinely conditional and conversion modelling switched on, usually measures better than a botched setup. That's what we audit.
Cookies, tags and consent, end to end
Real inventory of cookies and trackers
We crawl the site and compare what actually gets set against what the banner and the cookie policy declare. They almost never match.
Banner and CMP against the AEPD's guidance
Rejecting as easy as accepting, no walls or dark patterns, correct categories, accessible withdrawal and a record of consent.
Consent Mode v2 and lost measurement
Basic or advanced mode, signals sent by default and after consent, and how much of your measurement you're losing to implementation errors.
Tag manager
What fires before consent, which tags are not conditional and which vendors receive data with no legal basis. GTM, sGTM and equivalents.
Fix plan ordered by impact
A list of changes ranked by how much measurement each recovers and how much risk it removes, with instructions your agency or your team can carry out.
One report for two readers
The same audit serves marketing (what measurement you get back) and the DPO (Data Protection Officer) or legal (what non-compliance you close). No translating between departments.
- —Implementing the changes in your tag manager or your CMP (consent management platform): we give you the exact instructions; your team, your agency or we as a separate project carry them out.
- —Writing the cookie or privacy policy from scratch: we review it and mark what to fix; a full rewrite is a separate engagement.
- —Auditing mobile apps or native SDKs: the scope is web (including subdomains and campaign landing pages).
- —Guaranteeing a figure for recovered measurement: it depends on your traffic and your banner; we give you the diagnosis and the plan, not a promise.
- Deliverable
- A report with the tracker inventory, findings against the AEPD's cookie guidance, a Consent Mode v2 diagnosis and a prioritised fix plan, plus a presentation session with marketing and legal.
- Duration
- About 3 weeks from the moment we have read access to GTM and the CMP.
- Price
- Fixed price, agreed in writing before we start, based on the number of domains and the complexity of the stack.
- Next step
- Tell us your domain and which platforms you use (GA4, Ads, Meta, CMP) and within 48 hours we tell you whether there are signs of lost measurement and what the audit's scope would be.
