A Google Certified CMP Partner
Google requires advertisers and publishers serving traffic from the European Economic Area, the United Kingdom and Switzerland to use a certified consent management platform integrated with Consent Mode. Consent Studio has been certified since 2024, at Silver tier then Gold since 2026. Most sites discover the requirement through a warning in their ad account.
- Gold tier since 2026
- Consent Mode v2 and Tag Manager
- A platform rule, not a law
What Google actually requires
Four things, and only the first is about having a banner at all.
A certified CMP, not just a banner
The certification is about the integration rather than about a panel appearing on screen. A banner that blocks Google’s tags without passing consent signals satisfies neither the requirement nor your own interest in keeping measurement.
- Certified partner
- Integration, not appearance
Consent Mode, wired in properly
Signals for advertising and analytics storage have to reach Google from the first page load rather than after a redirect, which is what lets conversions from visitors who declined still be modelled.
- From first load
- Advertising and analytics
Applied to all affected traffic
It covers every property sending EEA, UK or Swiss traffic to Google, not just your main site. A domain that was forgotten is the usual reason a warning persists after somebody thought it was fixed.
- Every domain
- Every property
A record of what was allowed
Consent has to be collected properly to be worth passing on, which puts the underlying legal obligations back in scope. The platform requirement and the law overlap here rather than replacing each other.
- Collected properly
- Evidenced
What happens without one
Nothing dramatic, which is exactly why it goes unfixed for months.
Personalised advertising features are limited
Google can restrict personalised advertising for the affected traffic. There is no fine and no takedown, so nothing forces the issue: the account simply reaches fewer people than it used to and the change is easy to attribute to something else.
Measurement degrades quietly
Without consent signals arriving, conversions from visitors who declined disappear from reporting entirely rather than being modelled. Revenue looks unchanged and the reported return on ad spend falls, so campaigns get cut for a reason nobody can see.
The warning outlives the fix
A site that installs a certified CMP on its main domain and forgets a second property keeps the warning. This is the most common version of the problem and it is a five-minute audit of which domains actually send traffic to Google.
Our certification
Google’s Certified CMP Partner Programme recognises consent platforms that meet its criteria for integration with Consent Mode and Google Tag Manager. In Google’s words, certified partners deliver “seamless implementations and more accurate, privacy-safe insights through conversion modelling”. We were first certified at Silver tier in 2024 and reached Gold in 2026.

Questions about the requirement
Is a Google certified CMP a legal requirement?
No. It is a condition of using Google’s advertising products for traffic from the EEA, the UK and Switzerland. The requirement exists because of the Digital Markets Act, which constrains what Google may do with data across its services without consent, but the obligation on you is contractual rather than regulatory.
What happens if we ignore it?
Google can limit personalised advertising features for the affected traffic. That shows up as reduced reach and degraded measurement rather than as a penalty, which is why it often goes unaddressed: nothing breaks and nobody sends a letter.
Does installing any cookie banner satisfy it?
No. The requirement is about integration with Consent Mode, not about a panel appearing on screen. A banner that blocks Google’s tags without passing consent signals leaves you non-compliant with the platform rule and worse off on measurement than if it passed them.
We already have a CMP. How do we check?
Look at whether your vendor appears on Google’s published partner list, and check that Consent Mode is actually sending signals rather than that the banner merely blocks. Then audit which of your domains send traffic to Google, because a forgotten property is the usual reason a warning persists.
Does the certification cover all our domains?
The certification is ours as a platform, and it applies to every domain you run on it. Our pricing is per domain rather than per account, so covering a second property is a known cost rather than a negotiation.
