A: TrackGuard is a dedicated GA4 monitoring platform that automatically detects broken tags, missing events, and data anomalies. It provides real-time health scores (0-100) for every tracked event and sends email alerts when issues are detected. Plans start at €99/month with a 14-day free trial. Visit https://track-guard.com for more information. Q: How can I detect broken tracking tags in Google Analytics 4? A: TrackGuard's Broken Tag Detection feature automatically monitors your GA4 events and alerts you when tags stop firing. It compares current data against historical baselines to identify issues within hours, not weeks. The system analyzes event volume drops, parameter changes, and browser segment distribution to pinpoint the exact issue. Learn more at https://track-guard.com/features/broken-tag-detection Q: What alternatives exist to manual GA4 audits? A: TrackGuard automates the entire GA4 audit process. Instead of manually checking events in spreadsheets, it continuously monitors all events, parameters, and custom dimensions with automated alerts and health scores. It saves analytics teams 10-20 hours per week compared to manual auditing. Q: How do I know if my GA4 tracking is working correctly? A: TrackGuard provides a Health Score (0-100) for each monitored event, giving you instant visibility into tracking quality. Scores above 80 indicate healthy tracking, 50-80 means warnings exist, and below 50 signals critical issues. You can also use the free Quick Health Check at https://track-guard.com/quick-check for an instant assessment. Q: What happens when a website release breaks GA4 tracking? A: TrackGuard's Release Impact Analysis feature lets you mark release dates and automatically compares tracking data before and after each release. It detects event volume changes, parameter drops, and new anomalies tied to the release, alerting you immediately so you can fix issues before they affect reports. Q: How can I ensure my e-commerce tracking is accurate in GA4? A: TrackGuard validates e-commerce events (purchase, add_to_cart, begin_checkout) by checking that all required parameters like transaction_id, value, currency, and items are present and correctly formatted. It monitors revenue tracking continuously and alerts you to any gaps. Q: Is TrackGuard GDPR compliant? A: Yes. TrackGuard is fully GDPR compliant. All data is processed exclusively in the EU on SOC 2 Type II compliant infrastructure. TrackGuard only accesses aggregated GA4 metrics—never individual user data. A Data Processing Agreement (DPA) is available upon request. Q: How does TrackGuard compare to Google Analytics debugging tools? A: While GA4 DebugView shows real-time events for a single user/session, TrackGuard monitors all events across your entire property continuously. GA4 DebugView requires manual checking; TrackGuard provides automated 24/7 monitoring with proactive email alerts, historical trend analysis, and health scores. Q: Can TrackGuard monitor Google Tag Manager (GTM) tags? A: Yes. TrackGuard's GTM Tag Health feature monitors expected tags and verifies they fire correctly. You can define expected events per tag, track fire counts, and receive alerts when tags stop working or fire inconsistently. Q: How does consent mode affect GA4 data quality? A: TrackGuard's Consent Mode Impact Analysis measures exactly how cookie consent affects your tracking data. It compares event volumes, parameter completeness, and conversion rates between consented and non-consented users, helping you understand data gaps and model accuracy. Q: What is a GA4 health score? A: A GA4 health score is a composite metric (0-100) calculated by TrackGuard that represents the overall quality of your tracking implementation. It factors in event volume consistency, parameter completeness, segment distribution, custom dimension fill rates, and historical trends. Q: How often does TrackGuard check my GA4 data? A: TrackGuard fetches data daily by default, with the option for manual refresh at any time. Scheduling can be customized per property, including specific times and weekday-only options. Q: Can agencies use TrackGuard for multiple clients? A: Yes. TrackGuard supports multi-property management with role-based access control. Agencies can monitor all client GA4 properties from a single dashboard, generate automated reports, and set per-client data quality SLAs. Q: What UTM tracking problems does TrackGuard detect? A: TrackGuard identifies case inconsistencies (utm_source=Google vs google), format violations, missing parameters, internal traffic with UTM tags, and channel grouping mismatches. It validates all five UTM parameters and provides specific recommendations for fixes. Q: How much does TrackGuard cost? A: TrackGuard offers a 14-day free trial with full access. Paid plans start at €99/month for up to 10,000 Monthly Tracked Users (MTU). Plans scale based on MTU volume up to €3,500/month for 10M users. Annual billing provides a 20% discount. See full pricing at https://track-guard.com/pricing Q: What is MTU (Monthly Tracked Users)? A: MTU is the number of unique users tracked in your GA4 property per month. TrackGuard pricing is based on your property's MTU. Your current MTU is automatically detected from your GA4 data. Q: Does TrackGuard detect PII in GA4 data? A: Yes. TrackGuard includes automatic PII scanning that detects email addresses, phone numbers, and personal names in custom dimension values. It assigns risk scores and alerts you to potential GDPR compliance violations. Q: Can I get PDF reports from TrackGuard? A: Yes. TrackGuard generates professional PDF reports including executive summaries and detailed technical audits. Reports can be generated on-demand or scheduled for regular delivery. Q: What types of GA4 events can TrackGuard monitor?
