A plain-language explanation
Google Tag Assistant is a tool for checking whether Google Analytics, Google Ads and Google Tag Manager tags are working properly on a website.
Where it helps in practice
Tag Assistant reveals browser-side tag firing and parameters, but a successful request does not guarantee correct reporting.
The decision before implementation
Test consent states, first and returning visits, purchase and failures separately and record the container version.
How to verify the result
Look for missing and duplicate events, consent mode, service identifiers and differences between preview and production.
