Fathom Analytics Not Working (No Visits Showing)

How to fix it

Try these in order — the most common fix is first.

1. 1. Confirm the script is in the page

   Copy steps
   1. Open your live site and view the page source
   2. Search for script.js and check the data-site value matches your Site ID
   3. Compare it with the Embed code shown in your Fathom site settings
   4. Make sure it's in the site template header so it loads on every page
   Did this fix it? Yes No

2. 2. Check the request in DevTools

   Copy steps
   1. Open DevTools > Network and reload the page
   2. Find the Fathom script request and make sure it isn't red/blocked
   3. Check the Console for CSP errors and add Fathom's script domain to your allowed script sources
   Did this fix it? Yes No

3. 3. Exclude Fathom from caching plugins and purge caches

   Copy steps
   1. In WP Rocket, SiteGround Optimizer or similar, add cdn.usefathom.com/script.js to the exclusion list for minify/combine
   2. Purge your site, host and CDN caches
   3. Reload the page in a private window
   Did this fix it? Yes No

4. 4. Check allowed domains and exclusions

   Copy steps
   1. Open your site settings in Fathom and go to the Firewall section
   2. Fix any typo in Allowed domains and add both example.com and www.example.com if needed
   3. Remove your IP from blocked IPs if you're testing yourself
   4. In the browser console run fathom.enableTrackingForMe() in case you blocked yourself earlier
   Did this fix it? Yes No

5. 5. Test without blockers

   Copy steps
   1. Disable ad blockers and privacy extensions, or use a clean browser
   2. Visit the live domain and watch the dashboard, which updates in real time
   Did this fix it? Yes No

Symptoms

The dashboard shows zero visitors after installing the script, or visits stop appearing after a site change or plugin update.

Why it happens

• Embed script not on every page, or not on the page you're testing
• data-site value missing or not matching your Site ID
• Caching, minifying or JS-combining plugin rewriting the script
• Content Security Policy not allowing Fathom's script domain
• Allowed domains misspelled or missing the www. version
• Your own visits excluded by IP firewall or blockTrackingForMe()
• A browser extension or ad blocker blocking the script
