UTMGuard is a tool that scans Google Analytics 4 properties to identify UTM tracking errors that distort marketing attribution data. The platform automatically detects broken or inconsistent UTMs across campaigns, sources, mediums, and content by ingesting GA4 events.

Key features include automated scanning that runs daily in the background without manual exports or CSV uploads, advanced validation with over 40 rules to catch various UTM errors, and comprehensive issue detection covering missing utm_source or utm_medium, case-mismatched campaign names, internal links carrying UTMs, self-attribution loops, campaign name typos, UTMs dropped on redirects, inconsistent source/medium pairs, and invalid characters in UTM values. The system provides a UTMGuard Score (A–F) as a single grading metric, daily and weekly alerts for new errors, guided fixes with copy/paste-safe UTMs and playbooks per issue, and export capabilities for reports in CSV format.

The platform operates with read-only access to GA4 properties, ensuring safety without injecting scripts or modifying data. It automatically ingests GA4 events to detect broken UTMs without requiring manual entry. The scanning process typically delivers results in under 60 seconds by analyzing 30 days of GA4 data.

Benefits include preventing the loss of 10-15% of marketing budgets to tracking errors, maintaining clean GA4 data through continuous monitoring, and providing teams with actionable insights through resolution guides and alerts. Use cases span individual marketers needing to validate their campaign tracking, marketing teams requiring collaborative error monitoring, and agencies managing multiple client GA4 properties with separate workspaces.

Target users include performance marketing professionals, marketing teams, and agencies working with GA4 data. The platform supports unlimited users and workspaces with property-based pricing, offering team collaboration features and custom integrations for agency clients. Technical implementation requires only read-only GA4 access with no tracking code modifications needed.
