What the scan checks
Google Tag Manager
Finds every GTM container on the page, then inspects each container's configuration to report the tags inside it — GA4, Meta, Google Ads, legacy UA, and custom HTML tag counts.
Google Analytics 4
Detects gtag.js installations, G- measurement IDs, and consolidated GT- Google tags — resolving the GA4 destinations configured behind them.
Meta Pixel
Finds fbq initialization calls and noscript fallbacks, reports every pixel ID, and flags the same pixel initialized twice — a classic cause of inflated Meta results.
Google Ads & legacy tags
Detects AW- conversion tags, and warns about leftover Universal Analytics tags that have silently received data going nowhere since July 2023.
Installed is not the same as working
This scanner answers the first diagnostic question: is the tag on the page? But most expensive tracking failures happen after installation — a deploy renames a trigger, a consent tool update suppresses a segment, a checkout redesign breaks the purchase event. The tag is still "installed." It just stopped firing.
That's the gap between an audit and monitoring — covered in more depth in audit vs. monitoring and GA4 purchase event not firing.
