Every flaw in your analytics, surfaced at once.

No LLM guesswork — every check is deterministic, evidence-backed, and paired with a specific fix and a suggested owner.

GTM Container Health

Detects duplicate GA4 config tags, overlapping triggers, risky custom HTML, and stub tags with no event names.

Consent Mode Compliance

Checks whether GA4, Ads, and Floodlight tags are properly gated before cookie consent is granted.

GA4 Event Quality

Validates event names against GA4 taxonomy, flags missing required parameters, and catches duplicate events.

UTM Attribution

Synthetic UTM test on internal links reveals if campaigns are being stripped mid-session, breaking channel data.

Tag Presence & Coverage

Crawls up to 5 same-domain pages and flags any missing GTM or GA4, including JS-loaded tracking.

Traffic Intelligence

Parses GA4 Traffic Acquisition exports to surface unassigned traffic, dark traffic, and low key event rates.
