What this developer tool does
The tool creates crawler-access directives and highlights rules that block the entire site or expose sensitive path names.
Load preset or raw rules → normalize directives → remove duplicates → validate groups → test the supplied path.
Robots.txt controls crawling behavior; it is not an access-control system and does not guarantee de-indexing.
Example
A wildcard group can allow the site while disallowing /admin/ and declaring the sitemap URL.
Tips for better output
- Use
Disallow: /only when full blocking is intentional. - Do not list secret paths as a security measure.
- Pair indexing decisions with page-level robots directives where appropriate.
FAQ
How do I create a robots.txt file that allows all crawlers?
Use User-agent: * followed by an empty Disallow directive or an Allow: / rule.
How do I block an admin folder in robots.txt?
Add a Disallow directive for the admin path under the relevant user-agent group.
Does robots.txt remove a page from Google search?
No. It controls crawling and does not always remove an already indexed URL.
How do I add a sitemap to robots.txt?
Add an absolute Sitemap directive, usually near the end of the file.
How do I test whether a URL is blocked by robots.txt?
Compare the path against the most specific matching allow and disallow directives.
