Product summary

We’re grateful for your feedback—we've listened and will be updating and bringing back the on-page debugging experience. More exciting features are on the way.
Tag Assistant helps you install and troubleshoot your Google tags, including Google Analytics, Google Ads, Tag Manager and more. When clicked, the extension displays the Google tags found on the page in a side-panel. Just navigate to any page, and Tag Assistant will tell you which tags are present. We will be adding additional diagnostics in the near future.
The “Troubleshoot” button activates our debug mode using tagassistant.google.com. This advanced tool allows you to debug your website, including iframes, within a single session, providing detailed diagnostics to help you validate, diagnose, and resolve your implementation. Session data is available for review on tagassistant.google.com.
COMING SOON: Step-by-step guidance to install tags on popular website builders.

Used to be good, but hasn't been updated for so long that the new placement of GTM isnt supported, and neither are the 7 char tags. Only good to show that the tag is installed but will always throw errors.
Güell
Google fix this tool, if you use it today on a new tag manager site, it will fail for no reason. It does not support tag manager account that have more than 6 digits. (new ones have 7)
good
Rozszerzenie bdb jednak brakuje weryfikacji tagów z 7 znakami czyli np. GTM-XXXXXXX , aktualnie obsługuje tylko GTM-XXXXXX Duży minus za to, błąd występuje od 2016 roku
This is a useful tool no doubt about it. But 11 months since any update, means it has not kept up with the changes in GTM. Too many false positives waste time in debugging possible problems. Not updating the GTM ID check to accept 7 character ID's is a serious miss. How long would that single change make dev team? The invalid ID error creates unnecessary worry and time wasting! From this: /^GTM-[0-9A-Z]{4,6}$/. to this: /^GTM-[0-9A-Z]{4,7}$/.
Detecta las etiquetas, pero la valoración si están bien o mal puestas no lo hace correctamente. Tengo mis etiquetas bien colocadas, pero la extensión sale en rojo, advirtiendo que no están correcta.
Excelente!!! Ajudou muito!
Was having problems with values in the dataLayer not being updated when expected. It turned out the problem was this extension, and all the JS errors it causes. Disabled it and the issue instantly vanished
Not updated, can't debug GA, Adwords :(
