How it works
What does this checker detect?
Google Analytics 4, Universal Analytics, Plausible, Fathom, GoatCounter, Umami, Simple Analytics, Pirsch, Matomo — and common cookie consent platforms (Cookiebot, OneTrust, Complianz, Borlabs, Iubenda, and others). It fetches your homepage HTML and looks for known script patterns.
When do you legally need a cookie banner?
Under GDPR and ePrivacy, you need informed consent before setting cookies or processing personal data for analytics. Google Analytics sets cookies and can identify individuals — it requires consent. Cookie-free, anonymised analytics tools (like Logly, Plausible, or Fathom) don't process personal data, so they don't require a banner.
This says I have GA but no banner — what should I do?
You have two options: add a compliant consent banner (Cookiebot, Complianz, or similar), or switch to a cookie-free analytics tool that doesn't require consent at all. The second option is simpler, faster, and removes consent dropoff from your data.
Can this checker miss things?
Yes — it only scans the homepage HTML at the time of the check. Analytics loaded lazily after user interaction, scripts loaded via tag managers that render asynchronously, or analytics on inner pages only may not be detected. It's a quick scan, not a full audit.
