Why it matters

No analytics or measurement capability was detected on the site. Without any analytics tool you cannot measure traffic, user behavior, or conversions. GA4, PostHog, Plausible, Fathom, Matomo, Umami, Mixpanel, Amplitude, Heap, Adobe Analytics, Segment, and similar tools all count. This affects crawlability, rendering, and whether the site can be interpreted correctly by search engines.

How we detect it

  • FreeSiteAudit flags this issue when the rule for ANALYTICS-GA4-001 fails and the page evidence points to Dom body.
  • You can usually confirm this by checking the page source or the relevant page settings inside your CMS.

Evidence examples

Check the affected page source, rendered output, or relevant CMS setting to confirm the missing or incorrect element.

How to fix it

  1. 1Install an analytics tool — GA4 is the most common, but any of PostHog, Plausible, Fathom, Matomo, Umami, Mixpanel, Amplitude, Heap, or Adobe Analytics also works
  2. 2If using Segment or another CDP, confirm events are routed to at least one analytics destination
  3. 3Verify data is actually flowing — for GA4 use the Realtime report; for others use their equivalent live view

How to re-check it

  • An analytics tool shows active users in its realtime view when you browse the site
