robots.txt Change Monitoring

Detect accidental changes that could de-index your site.

Start Monitoring Free← All Monitor Types

robots.txt monitoring fetches your robots.txt file on each check cycle and alerts you when the content changes. An accidental Disallow: / can block all search engines within hours.

How it works

Uptrue fetches /robots.txt from your domain and computes a SHA-256 hash of the content. If the hash differs from the previous run, a change alert fires.

What Uptrue checks

robots.txt accessibility (HTTP status)
Content hash change detection
File size

Alert conditions

robots.txt content changes from baseline
robots.txt returns non-200 status
Why this matters

A single line change in robots.txt can tell Google to stop crawling your entire site. This has happened to major brands during CMS migrations and framework upgrades.
