Audit the client's Tag Manager before you spend their budget
Claude reads the container, lists the tags and their triggers, and points out what is not being measured, what is duplicated and what is broken. Read-only: it publishes no changes to your container.
The inventory, in a minute
Reachable containers, published version, tag count, triggers and variables. What is normally twenty minutes of clicking through the GTM interface comes back as an answer.
The gaps, pointed out
The audit cross-checks what is configured against what should be there: conversions with no tag, duplicated events inflating the numbers, and tags pointing at properties that no longer exist.
Checked against Ads and Analytics
Because Claude also reads the same brand's Google Ads, Meta Ads and Analytics, it can compare what is measured with what is reported and explain why two numbers disagree.
Read-only by design
No GTM tool writes to your container. You can audit client accounts with no risk of publishing a version nobody reviewed.
The right order: measure, then invest
The awkward conversation with a client is almost never about campaign performance: it is about why the Ads dashboard says one thing and Analytics says another. By the time that surfaces mid-month, budget has already been spent on decisions made against the wrong numbers.
Reviewing the container up front is cheap and avoids exactly that. The problem is that doing it by hand on every onboarding is tedious, so it gets skipped.
A good first onboarding prompt
"Audit this brand's Tag Manager and tell me what is unmeasured before we launch campaigns" is one of the highest-return things to ask Claude in a new client's first week.
The answer doubles as a document: a concrete, prioritised list of fixes you can hand to the technical team or quote as separate work.
