// Why it matters

Check the whole consent journey.

Consent Mode adjusts Google tag behaviour using consent signals. Storage, advertising data use and personalisation have distinct controls. We check those signals together, from the initial page load through the visitor’s choice.

Google’s June 2026 data-control update makes Consent Mode central to GA4 advertising data sharing. We review the complete configuration and test accept and reject paths; modelling is subject to Google’s eligibility requirements.

// What we verify

Test the choices visitors can make.

Check the initial state, accepting optional tracking, rejecting it and changing a saved choice. Inspect both cookies and requests, then compare the result with your platform diagnostics.

Consent Mode is a technical integration, not a certification of legal compliance. Read Google’s Consent Mode overview.

// Common questions

Questions we get asked.

What does Consent Mode v2 add?

It adds ad_user_data and ad_personalization to the existing storage signals. These control advertising data use and personalised advertising. We review all relevant signals rather than treating one setting as the whole implementation.

Will Consent Mode reduce my conversions?

Consent choices affect what can be collected and used. Eligible implementations can use Google’s modelling, but it does not recover every unobserved conversion. We check configuration and reporting before drawing conclusions about a change.

Do we need a specific consent banner?

Consent Mode can work with a compatible CMP or a custom consent solution. Requirements vary by Google product and use case. We assess your existing banner and recommend the integration needed for your setup.

How do you prove it is working?

We test default and updated states, inspect cookies and network requests, and check the relevant platform diagnostics. We record what was tested and what still needs account-level or legal review.
