Benefits

- Quickly identify untagged pages
- Validate improvements to tag coverage
- Download a URL-level summary of tagged status
How it works
To accurately measure the effectiveness of your website and ads, you should install the Google tag on each page of your website. To test if your Google tag works, use Google Tag Assistant. Google Tag Assistant can also identify untagged pages and add them as suggestions to your "Tag coverage" summary. The "Tag coverage" summary shows you which pages have the Google tag correctly implemented. Your "Tag coverage" summary can report on up to 10,000 pages.
How to find the summary
For Google Ads and Google Analytics,
- Access your Google tag screens.
- Go to the "Admin'' tab.
- Under "Tools," click Tag coverage.
Google Tag Manager instructions
- In Google Tag Manager, click Admin.
- In the "Container" section, click Tag coverage.
Understand the summary
The "Tag coverage" summary consists of the "Page details" table, which has columns for "URL" , "Landing page", "Conversion path", and "Tag status". You can hover over the annotations in the columns on your summary page to learn more about your tag coverage.
The "URL" column shows individual pages from your site. (Note that it shows the domain and path only and doesn't include query parameters.)
The “Landing page” column shows a checkmark when a URL is the entry point for a website. You can review your landing page metrics to measure organic traffic.
The “Conversion path” column shows a checkmark when a URL is part of a Google Analytics or Google Ads conversion path or conversion goal. You can review your conversion paths to measure Google Ads attribution.
The "Tag status" column shows one of the following statuses for the URL:
- Not tagged: Pages that have never loaded your Google tag
- No recent activity: Pages that haven’t loaded your Google tag in the last 30 days, but have in the past
- Tagged: Pages that have loaded your Google tag in the last 30 days
The cards above the table summarize the number of pages included in the summary, plus the number of pages that are not tagged, have no recent activity, or are tagged. Click a card to quickly review all URLs with those statuses.
Suggested pages
In some rows, you'll notice a "Suggested" label next to the URL. Suggested pages are pages that Google has detected and included in your "Tag coverage summary" table. Suggestions may not include every page that has a Google tag. You may want to add suggested pages to confirm that you accept the page as part of your summary. Suggested pages are removed from the summary after 60 days of inactivity unless you choose to keep them or add them individually. Keeping suggested pages allows you to later revisit whether they should be included in the summary without them being removed due to inactivity.
To accept a suggested page as part of your summary, hover on a row, and click Add . You may also click Ignore (-) to ignore the suggestion, or click the tag icon to open the page in Tag Assistant. Ignoring a page or suggestion will omit the row from the tag summary.
To add or ignore multiple suggested pages, select the checkbox next to the rows you want to add/ignore, and click Add or Ignore (-) at the top of the table, next to the search icon.
Add URLs
If you notice that the summary doesn't include all of the pages from your site, you can add URLs.
To add URLs:
- Click the "Add URLs" icon
to add pages to your summary.
- Select either Add URLs or Upload a CSV file.
- Depending on your selection in the previous step, do one of the following:
- To add URLs:
- Enter a list of the URLs you want to add to your tag coverage summary. Separate each URL with a line break.
- Click Add.
- To upload a CSV file:
- Click Select a CSV file.
- The CSV file should be formatted as <URL>,<Included status>
- example.com/2,no
- example.com/3,yes
- You may optionally include a header row.
- You can alternatively download your current tag coverage summary as a CSV file (review instructions below) and make changes.
- Each URL should be percent encoded.
- The CSV file should be formatted as <URL>,<Included status>
- Select either:
- Overwrite: Replace all the URLs in your current tag coverage summary with the contents of your CSV file.
- Merge: Add new URLs and update any URLs already in your summary.
- Click Upload.
- Click Select a CSV file.
- To add URLs:
Pages you’ve added to your summary may not update status for up to 24 hours after they've loaded a tag.

Find and fix untagged pages
When using Tag Diagnostics, you may encounter the critical issue, "Some of your landing pages are not tagged." A similar issue, "Some of your pages are not tagged," may also arise for untagged website pages, which also affects data quality and measurement accuracy.
Find untagged pages
If Tag Diagnostics flags either of these issues, you can open the Tag coverage summary for a concise list of detected URLs that correspond to untagged pages and landing pages.
Fix untagged pages
To address these issues, follow these steps:
- Open the Tag coverage summary for a list of URLs alongside their 'Tag status'.
- Review the Page details table within the summary. Pages marked as 'Not tagged' indicate the absence of necessary tags. You can hover over the 'Not tagged' status for more information about the issue. You can also refer to the 'Landing page' column for landing pages.
- For each page or landing page listed as 'Not tagged', either install the Google tag or install the Google Tag Manager container on your website.
- Refer back to the Tag Diagnostics to verify that the tags have been set up correctly. You can also verify your setup with Tag Assistant to ensure the tag is firing correctly. If you recently installed the Google tag or the Google Tag Manager container, it can take up to 24 hours for the Tag coverage summary to update with your tagged page.
Identify false positives and duplicates
Tag diagnostics may falsely raise warnings in the Untagged Page section of Tag coverage when a page is correctly tagged. The following are the most common reasons why this might happen and how you can fix these issues when they arise:
- Low Traffic: Pages with low traffic might be mistakenly identified as untagged, even if they’re intentionally low-traffic pages. For example, thank you pages after ordering an item might be flagged as untagged pages.
- Redirects: Pages that serve as redirects (for example, from http://example.com to http://www.example.com) might be mistakenly flagged.
- Trailing Backslashes: Pages with and without trailing slashes (for example, http://www.example.com/ and http://www.example.com) can cause the same page to be flagged twice as untagged.
- Capitalization: Variations in URL capitalization can lead to the same page being flagged as separate untagged pages. For example, http://www.example.com/ABC and http://www.example.com/abc might be mistakenly flagged as separate pages.
To fix these common issues:
- Verify that your page is correctly tagged using Tag Assistant.
- Ignore the page in Tag coverage, which will remove the issue from appearing about the page. You can always add the page back into Tag coverage later.
