See what is actually in your Tag Manager container.
Cresva reads your Google Tag Manager container itself, so it finds duplicate purchase tags inflating ROAS and tags that can never fire. Free to run.
This one needs your Tag Manager grant
The other tracking tools read a page anyone can visit. This one reads inside your container, which is the only way to see a paused tag, a tag with no trigger, or a duplicate that happened not to fire on the page we looked at. That needs your permission, so there is no version of it we can run for a stranger.
Sign in and connect Tag ManagerWhat is in your container is one half of a tracking question, and what reaches a visitor is the other. Tag hygiene is one of seven checks in the full growth audit, which also reads your public catalogue, your landing page, your schema markup and whether ChatGPT and Claude name you when asked what you sell.
