001WHY IT HAS BECOME ESSENTIAL
A legal obligation,
a performance issue.
GDPR and DMA
No advertising data may be collected without the explicit consent of European visitors.
Required since March 2024
Google requires Consent Mode v2 from advertisers targeting the European Economic Area for measurement and remarketing.
Signal or nothing
Without consent signals, Google tags can no longer use your data: lost conversions, empty audiences, blind bidding.
002THE DIFFERENCE IN ONE CLICK
What Google
actually receives.
We use cookies to measure our audience and personalise our ads.
Some of your visitors decline cookies. Depending on your setup, here is what happens to their data.
Either the tags fire without consent (not GDPR compliant), or the banner blocks them. Either way, Google does not receive the expected consent signals: conversions go unmeasured, remarketing is disabled for Europe and Smart Bidding is starved of data.
Google tags wait for the visitor's choice. If they accept, everything is measured. If they decline, nothing is sent: Google applies a general, less accurate model, and your campaigns lose part of their signal.
Tags load on arrival and respect the visitor's choice. If they decline, only anonymous cookieless pings are sent: Google can then model the missing conversions far more accurately.

004CONSENT MODE FAQ
Frequently asked
questions.
Is a cookie banner enough?+
No. The banner collects the choice; Consent Mode passes it on to Google. Without that link, your tags don't know what to do with the data.
How do I know if my site is compliant?+
Google Ads shows a consent diagnostic in your conversions. We check it for free during the audit, along with a full test of your banner.
Basic or advanced: which should I choose?+
Advanced mode recovers more modelled conversions. The choice depends on your privacy policy and your sector: we help you decide.
