Common errors

A page URL is pasted instead of the domain root.

Fix: Use the main site URL or domain. The tool will check /robots.txt on that origin.

The site blocks remote fetching or the request fails.

Fix: Retry with the full URL and compare the result manually in the browser if needed.

Users think robots.txt guarantees no indexing.

Fix: Remember robots.txt controls crawling, not always indexing behavior.
