Growth audit module · Tracking & consent

Tag Manager audit

Underneath your website sits a layer of tracking tags that feeds every report, every ad platform and every dashboard you rely on. It rarely gets looked at. This audit does.

Sound familiar?

  • You can't say what's actually tracking on your website.
  • Ad platforms report conversions your CRM has never heard of, or miss ones it has.
  • Legal asked "are we compliant with the cookie rules?" - but the answer is ambiguous.
  • Reports shift from one month to the next and there's no way to know if tracking changed or performance changed.

What the audit tells you

What actually fires

A complete, evidenced picture of every tag running on your site - including the ones installed and never removed.

Silent failures

Conversion tags that never fire, fire twice, or send data to the wrong place - corrupting every report downstream without anyone noticing.

Consent & privacy risk

Whether tracking respects your visitors' cookie choices - tested live, on your real site - and where you're exposed under UK and EU privacy law.

Who holds the keys

Who can publish changes to your live site's tracking - including former agencies and dormant logins that should have been removed years ago.

Dead weight

Zombie tags from cancelled tools and old campaigns that slow your site down and leak data for nothing in return.

What to fix first

Findings ordered by exposure: legal risk first, corrupted measurement second, housekeeping last.

Found in real audits

Recent findings from delivered audits, anonymised.

31 of 33

On one B2B site, 31 of 33 tracking tags had no consent rules at all - firing before visitors agreed, and continuing after they declined.

1 of 19

Just one of 19 Google Ads conversion actions was actually wired into the container - and the Meta pixel was installed three times, once with a broken ID.

Consent: faked

A UK site was telling Google that visitors had consented when they hadn't - with three trackers still firing after every cookie category was declined.

Frequently asked questions

What is a Google Tag Manager audit?

A review of the tracking layer that sits underneath everything - the container of tags that feeds your analytics, your ad platforms and your CRM. It checks what actually fires on your site, whether conversions are wired correctly, whether tracking respects visitors' cookie choices, and who is able to change any of it.

Why should a CEO care about tag management?

Two reasons: money and risk. Money, because a miswired container corrupts every number downstream - one audit found only 1 of 19 Google Ads conversion actions actually wired up, so the ad budget was flying blind. Risk, because tags that fire without consent are a live privacy-law exposure in the UK and EU, and it's leadership that carries it.

Is consent really a problem in practice, or just a theoretical one?

In practice. Recent audits found a site where 31 of 33 tags carried no consent rules at all, and another where three marketing trackers kept firing after the visitor had declined every cookie category - while the setup told Google the visitor had consented. That's not theoretical; it's on the record for any regulator or litigant who looks.

What do you need from us?

Read-only access to the container, plus your live website - a large part of the audit is observing what your site actually does to real visitors, before and after their cookie choice. Nothing is changed.
