Maximizing Website Tracking with Google’s Tag Coverage Summary

Google’s Tag Coverage summary provides insights into how tags are performing across your website, covering up to 10,000 pages. This feature helps you identify which tags are firing properly and which ones are not. You can view the summary through the Google tag sections in Google Ads, Google Analytics, and Google Tag Manager (GTM).

How to Use the Tag Coverage Summary

Once you open the Tag Coverage summary, you can start reviewing your tags in detail. Here are some practical ways to use it:
