If you're researching automated GA4 audit tools, you've likely come across GA4Check alongside GA4 Health Check. Both tools aim to solve the same problem — identifying configuration issues in Google Analytics 4 properties. Here's how they compare across the dimensions that matter most for analysts and agencies.
Audit Scope & Depth
The fundamental question for any audit tool is: what does it actually check? GA4Check focuses primarily on tag-level verification — checking whether the GA4 tag is present on pages, whether basic events are firing, and surface-level configuration items visible without API access.
GA4 Health Check connects directly to the Google Analytics Admin API and Data API, running 47 checks across 7 modules: Account & Property Setup, Event Tracking Quality, Configuration & Customization, Data Integrity, Privacy & Compliance, Data Streams, and Reporting. This includes checks that are only accessible via authenticated API access — things like data retention settings, conversion event status, custom dimension configurations, and Consent Mode signal verification.
Report Output
GA4Check produces a summary pass/fail view that identifies issues but provides limited remediation guidance. GA4 Health Check generates a 20+ page scored PDF report with each finding categorized by severity (Critical, Warning, Pass, Info), accompanied by specific step-by-step fix instructions referencing the exact GA4 Admin menu or GTM configuration needed. The report is designed to be handed directly to a developer or presented to a client without additional interpretation.

| Pricing | Free / limited | From $179 per audit |
Which Tool Is Right for Your Use Case?
GA4Check is a reasonable quick check for a single surface-level concern — "is my tag firing on this page?" For that specific use case, it's free and fast. GA4 Health Check is built for a different purpose: a comprehensive data quality audit that covers every layer of the GA4 configuration, produces an actionable report, and is designed to be repeatable across multiple properties.
For agencies onboarding clients, the comparison isn't really about the tool — it's about what you need to stand behind your work. A free tag checker isn't sufficient to confidently tell a client their GA4 data can be trusted.
