Audit Modules
Property Configuration module (30 checks)
Inspects your GA4 property settings directly via the Admin API. The fastest module — and the most foundational, since most downstream data quality issues trace back to bad property settings.
Measurement IDs and data streams
Verifies at least one active web data stream with a valid measurement ID, and checks that the stream's website URL is populated and correctly formatted (the Tag & Consent module uses it for crawling). Multiple streams for the same domain are flagged — a common source of duplicate sessions.
Data retention settings
GA4's 2-month default is too short for any property doing seasonal or year-over-year analysis. The module flags retention below 14 months, since shorter retention kills your ability to compare against prior periods.
Google Signals and demographic data
Google Signals enables cross-device tracking and demographic reporting. The module checks whether it's enabled and whether thresholding (which suppresses small demographic segments to prevent fingerprinting) is creating reporting gaps. Signals on with thresholds suppressing your data raises a high-severity finding.
Timezone and currency
A wrong timezone shifts session boundaries and date-based metrics by hours. The module verifies your property timezone matches your business region. Currency mismatches between the GA4 property and your e-commerce implementation are flagged high-severity.
Enhanced measurement and referral exclusions
Enhanced measurement auto-tracks scrolls, outbound clicks, site search, video, and file downloads. The module flags features that risk double-counting — for example, manual page_view events alongside enhanced measurement page_view tracking.
Referral exclusion lists are checked for missing payment gateway domains, which cause session interruptions and inflate direct traffic.
Linked services
Checks Google Ads (conversion import), Search Console (organic search data), and BigQuery (raw export) link status. Missing links relevant to your property type appear as medium-severity recommendations.
