Connect Google Analytics and GA4 Sensei runs 100+ checks across your GA4 property and Google Tag Manager container — then shows you exactly what's broken and how to fix it. No credit card.
Example score from a real audit
Data streams, enhanced measurement, cross-domain setup, data retention and the settings that decide what GA4 records at all.
Duplicate tags, spam and bot traffic, (not set) values, self-referrals, ghost referrals and UTM hygiene — the issues that quietly distort reports.
Consent Mode signals, cookies set before consent, IAB TCF, and personal data such as emails leaking into page URLs and events.
Key events, Google Ads and Search Console links, BigQuery export, audiences and custom definitions — whether your data is actually put to use.
Plus a full Google Tag Manager audit when you link a container: triggers, events, ecommerce, governance and consent.
An example finding, exactly as it appears in a report.
Finding: Event data retention is set to 2 months.
Why it matters: Explorations, segments and the Data API use event-level data, which expires on this setting. At 2 months, year-over-year analysis in Explorations is impossible.
How to fix: Admin → Data Settings → Data Retention → set event data retention to 14 months.
