100+ automated checks
Everything your GA4 setup needs, audited automatically
GA4 Sensei checks your GA4 property and Google Tag Manager container end to end — then tells you what's wrong, why it matters, and how to fix it.
GA4 audit
A health score for every part of GA4
Data collection, data validity, insight activation, consent and PII, and app tracking — each section scored and weighted, with every check marked passed, warning or critical so you know where to start.
Every finding explained
Know why it matters and exactly how to fix it
Open any check to see what was found, why it matters, step-by-step fix instructions, an estimated time to fix, and the before/after impact — plus the raw data behind it.
Google Tag Manager
Audit the container that feeds GA4
Link a GTM container to run 20 checks across structural health, triggers and firing logic, events, governance, ecommerce and revenue integrity, attribution, privacy and infrastructure.
Combined view
GA4 and GTM side by side
See both health scores together and every critical issue from either source in one list — deliberately without a blended score, so one strong side can't hide a weak one.
One-click auto-fix
Review the change, then apply it
On paid plans, supported findings have a Fix It option. GA4 Sensei shows your current settings and the recommended change; nothing is written to GA4 or GTM until you click apply.
Monitoring & alerts
Get told when something breaks
Schedule re-audits weekly or monthly — daily on Growth and above — and get an email listing exactly which checks changed.
Also included
Consent & PII scanning
Consent Mode settings, cookies set before the user interacts with the banner, IAB TCF signals, consent banner presence and third-party pixels — and personal data such as emails in page URLs, titles and event parameters.
PDF reports
Download any audit as a PDF — GA4, GTM, or both combined — ready to share with a client or your team.
App tracking
For app streams: install, crash, revenue, screen and deep-link tracking, plus Measurement Protocol validation and secret hygiene.
