Why Accurate Tracking Matters
For any online business, accurate tracking is the foundation of decision-making. If your tags don’t fire correctly, the data you collect will be incomplete or misleading. Google’s Tag Coverage tool solves this by giving you a complete picture of how well your website tags are performing.
Understanding Tag Coverage
Tag Coverage, available in Google Tag Manager (GTM), scans your site and reports on the status of your tags. It shows:
- Total number of tags installed
- Tags that are firing correctly
- Tags that are not firing
- Pages with missing tags
- Tags showing no recent data
This makes it easy to monitor, troubleshoot, and ensure consistent tracking across your website.
Steps to Access Tag Coverage in GTM
- Log in to Google Tag Manager.
- Select the container you want to review.
- From the left-hand menu, go to Tags.
- Click on Tag Coverage to open the report.
You’ll now see a detailed overview of tag performance across your site.
