GA4 checker
Enter a store address and see which GA4 measurement IDs and tag containers the page loads.
Missing or double-counted GA4 data makes every decision after it unreliable. Run a free audit to see what else your store needs.
Questions
What does this check read?
The page's own HTML source. A tag added later by a tag manager may not appear. Open Google Tag Assistant to confirm.
What is double counting?
The same measurement ID loaded twice, so every visit and purchase is recorded twice.
I only see a Tag Manager container. Is that wrong?
No. GA4 is often loaded through the container, so the check lists it and tells you to open the container to confirm.
