Questions

How does it work?
We load the page the way a browser first receives it and look for the code each tool adds. If the page uses Google Tag Manager, we also open its public container file, because that is where many sites hide their GA4 and ad tags.
Why did it miss a tracker I know is there?
Some tags are added later by other scripts, only after someone accepts cookies, or only on certain pages. Tracker X-Ray reads one page as it is first sent, so try the exact page you care about. Sites behind strict bot protection may also block the scan.
What is a GA4 Measurement ID?
It is the code that starts with G-, and it tells Google Analytics 4 which property should receive the visit. If two sites show the same ID, they report into the same GA4 property.
The scan found Universal Analytics. Is that a problem?
Google switched Universal Analytics off in July 2023 (July 2024 for paid 360 accounts), so a UA- tag on its own records nothing. If there is no G- ID next to it, the site is not being measured at all.
Is it free? Do you keep the sites I scan?
Yes, it is free with no signup. We keep each result for an hour so repeat scans and shared links load fast, then it is deleted.
