TraceFindBot

If you found TraceFindBot in your logs, this page explains what it does. In short, it visits your homepage about once a month and reads what is publicly in it.

What it reads

DNS: your domain's A, NS and MX records.
Your homepage: one GET /, and nothing deeper. From the HTML it records the public analytics and tag IDs (Google Analytics, Tag Manager, AdSense and similar) and the site-verification tokens.

TraceFind uses this to show which websites share the same infrastructure or analytics accounts. Nothing else is stored: no page content, no personal data, no cookies.

How it behaves

It honours robots.txt for the user agent TraceFindBot (and *).
It sends one request for robots.txt and one for the homepage, about once every 30 days. It follows at most four redirects.
It only visits sites from the public Tranco top-sites list. It does not follow links, submit forms or probe for vulnerabilities.

Opting out

Add this to your robots.txt:

User-agent: TraceFindBot
Disallow: /
