Practical GA4, Google Ads and GTM review for UK websites

Google Consent Mode Audit for UK Websites

A practical review of how your cookie banner, Google tags and visible consent signals appear to work together.

A cookie banner can look correct while GA4, Google Ads or Google Tag Manager still need closer technical attention. We review the public visitor journey and visible consent-mode signals to identify practical questions for your developer, PPC agency or marketing team to investigate.

A practical website review, not legal advice, a compliance certificate, a Google approval process or a substitute for a full developer-side configuration audit.

What a Google Consent Mode audit checks

The review is built for websites using Google Analytics 4, Google Ads or Google Tag Manager. It focuses on the practical connection between visitor choices and the visible behaviour of Google-related tags and consent signals.

01 Consent signals

We consider visible evidence around the Consent Mode signals that Google tags may use, including analytics, advertising storage, advertising data use and personalisation choices.

02 Consent journey and tag behaviour

We look at the public journey before a choice is made, after rejection and after acceptance to identify whether the consent route and visible tag behaviour merit further review.

03 Practical technical handover

We translate findings into plain-English questions and prioritised checks for the people responsible for your CMP, GTM, GA4, Google Ads or website code.

The Consent Mode signals we can help you review

Google Consent Mode uses consent states to help Google tags adjust their behaviour according to visitor choices. The exact configuration depends on your platform, consent-management setup and the Google products you use.

Our role is to identify visible signals and questions that should be checked — not to assume that a public website test can see every setting inside your tag manager, consent platform or advertising account.

analytics_storage — analytics-related storage and identifiers.
ad_storage — advertising-related storage and identifiers.
ad_user_data — consent for sending user data related to advertising to Google.
ad_personalization — consent related to personalised advertising.

Where appropriate, the review highlights whether these areas appear connected to real visitor choices and whether a developer-side verification process is advisable.

GA4, Google Ads and GTM review areas

The audit is designed to surface practical issues that can arise when Google tags, a cookie banner and Consent Mode are installed separately or changed over time.

Google Analytics 4

We look for public indicators that GA4 or related analytics tags may need checking against the user’s consent choice, banner categories and declared cookie information.

Google Ads

We consider visible Google Ads, conversion or remarketing signals and whether advertising choices appear connected to the consent journey presented to visitors.

Google Tag Manager

We identify common public signs that GTM, duplicate tags, trigger setup or consent configuration may deserve closer investigation in the container and consent platform.

Tracking before consent: what the audit can identify

One of the most useful checks is the journey before a visitor chooses anything. A banner may be visible while tags, cookies or network activity still create questions that need confirming in the underlying setup.

We compare public behaviour before consent, after a rejection and after an acceptance where practical. Findings are framed as technical points to investigate — not as a definitive conclusion about every cookie, tag or legal requirement.

Typical questions for a developer or agency

Are default consent states set before relevant Google tags respond?
Does the banner update the consent state after a visitor makes a choice?
Do rejection and acceptance change only the intended categories?
Are GA4, Google Ads and GTM aligned with the consent-platform categories?
Are duplicate tags, plugins or third-party scripts affecting the intended behaviour?

Google Consent Mode audit FAQs

Does Google Consent Mode replace a cookie banner?

No. Consent Mode is designed to communicate consent status to Google tags. It works alongside a cookie banner or consent-management platform; it is not a banner or a complete consent solution by itself.

Does this audit confirm that our Consent Mode implementation is compliant?

No. The audit provides practical website observations and technical questions to investigate. It does not provide legal advice, certify compliance, guarantee Google eligibility or replace access to your GTM container, consent platform, analytics settings, advertising account or website code.

Can you check GA4, Google Ads and GTM?

Yes. The review can consider public indicators around Google Analytics 4, Google Ads and Google Tag Manager. A detailed implementation verification may require your developer or agency to check the underlying configuration and consent settings directly.

What is the difference between this and a cookie banner audit?

A cookie banner audit looks broadly at the visible consent journey, cookie information and common tracking signals. This service focuses more specifically on the relationship between visitor choices and Google Consent Mode, GA4, Google Ads and GTM.

What do you need to start?

For a free initial check, we normally need your public website URL and a way to contact you. It is helpful to know whether you use GA4, Google Ads, GTM, a consent-management platform, ecommerce tracking or enhanced conversions.
