Frequently Asked Questions

What does the GA4 Health Checker scan for?▾
It scans your page HTML for GA4 measurement IDs, GTM containers, Consent Mode configuration, dataLayer initialization, known third-party trackers, and common configuration issues like duplicate tracking or missing consent defaults.
How is the health score calculated?▾
The score starts at 100 and deducts 20 points for each error (e.g., duplicate tracking, missing consent mode), 10 for each warning (e.g., no CMP detected), and 5 for each informational finding.
What is Consent Mode and why does it matter?▾
Google Consent Mode lets you adjust how Google tags behave based on user consent. Setting a consent default before loading GA4 is required for GDPR compliance in the EU and for modeling conversions without cookies.
Why is consent order important?▾
The consent default must be set before any gtag config calls. If GA4 loads before consent defaults are applied, data may be collected without proper consent, violating GDPR and ePrivacy regulations.
What is a CMP and do I need one?▾
A CMP (Consent Management Platform) is a tool like Cookiebot or OneTrust that manages user cookie consent. If your site uses trackers that set cookies, EU regulations require you to obtain informed consent via a CMP.
Can this tool detect server-side tracking?▾
No. This tool analyzes client-side HTML only. Server-side GTM containers, GA4 Measurement Protocol hits, and server-side tag configurations are not visible in the page source.
Does a score of 100 mean my GA4 setup is perfect?▾
A score of 100 means no common issues were detected in the page HTML. It does not verify data accuracy, conversion tracking correctness, or server-side configurations.
