What we check
Detects GA4, GTM, Plausible, Matomo, and Piwik PRO directly in the HTML.
Why it matters
Without an analytics tag, nothing flows into Google Ads, Looker, or your reporting.
Common causes
- The site deliberately tracks server-side or cookieless, then the finding is expected and not an error.
- The tag sits behind the CMP blocking and only appears after consent, invisible to the static scan.
- After a relaunch the tracking snippet simply did not move along.
- An ad or tracking blocker at CDN level filters the known script hosts before delivery.
