Tag Inspector
Description
To check your site's tagging manually, we provide a browser extension for free called Tag Inspector.
It lets you see clearly all parameters generated by your tagging, as they should be listed in the interface.
But most importantly, it gives you warnings on the value sent in all parameters if they do not match the expectations, or if their format can be improved.
If you are logged in to your account, it automatically gets the detailed information of sites you've been given access to (gets your custom domains, replaces the site number by your site label etc...).
