Fathom Analytics Not Working? Common Errors & Fixes

If Fathom shows no visits, the embed script is usually missing from some pages, has the wrong data-site ID, is rewritten by a caching plugin, or is blocked by a CSP, allowed-domains setting or your own ad blocker. Check the page source and Network tab first.

Fathom records canonical URLs by default, so a canonical tag pointing to your homepage on every page makes all traffic show as '/'. Fix the canonical tags or add data-canonical="false" to the script.

Many blocklists block Fathom's cdn.usefathom.com script, and Fathom removed custom domains in March 2023 because blockers caught them too. There is no official bypass; existing custom domains still work, and some developers proxy the script themselves at their own risk.

Fathom custom events usually go missing because trackEvent runs before the script loads, the Firewall Events list blocks the name, or the event name uses special characters. Load the script first, then call fathom.trackEvent('name').

In single-page apps, client-side navigation doesn't reload the page, so Fathom only records the first view unless you add data-spa="auto" or call trackPageview on route changes. In Next.js App Router, use fathom-client with auto: false and a client component.

The Fathom WordPress plugin usually stops tracking because a caching or minifying plugin rewrites the script, your user role is excluded, or the Site ID is wrong. A 404 on the in-admin dashboard means sharing isn't set to Passworded or Public.

Fathom and GA count differently: Fathom resets unique visitors daily, filters more bots, merges URLs with query strings and loses visitors to ad blockers. Gaps are normal; compare only the same pages and dates.

Fathom only sees what the browser sends in the Referer header. Strict referrer policies, apps and emails strip it, so visits look direct or show only a domain. Tag your own links with UTMs and connect Google Search Console for keywords.

Search Console data in Fathom lags 2-3 days, so ranges ending today or yesterday look empty. Other causes are an expired authorisation, the wrong property, or viewing a public share link without a password.

Fathom locks dashboard and API access when usage stays well over your plan after reminders, or when an invoice is unpaid. Data keeps being collected; approving an upgrade or paying the invoice restores access.

Run fathom.blockTrackingForMe() in your browser console on your site, or add your IP to the site's Firewall settings. The console method is stored in local storage and is lost when you clear browser data.

Fathom's GA4 import can take up to 48 hours. If it fails, turn off 'Enable user metric reporting' in GA4 property settings and split large histories into one- or two-year ranges. Overlapping dates double your numbers.

Cookiebot treats Fathom like any analytics script and blocks it until consent. Fathom uses no cookies, so add data-cookieconsent="ignore" to the script tag to let it load.

Go to Settings > Billing and click Cancel in the Subscription section. Access lasts until the end of the billing period, there are no refunds except where required by law, and your data is queued for deletion (up to 60 days) after the subscription ends. Deleting the account instead wipes everything instantly.
