Frequently Asked Questions

What is a robots.txt file?▾
Robots.txt is a text file that tells search engine crawlers which pages they can or cannot access. It lives at the root of your domain (e.g., example.com/robots.txt).
Do I need a robots.txt file?▾
While not strictly required, having a robots.txt file is recommended. It helps search engines crawl your site more efficiently and can prevent indexing of private or duplicate content.
What does Disallow: / mean?▾
Disallow: / blocks all crawlers from accessing your entire site. This is useful during development but should be removed before launching. Be very careful with this directive.
Should I include a Sitemap directive?▾
Yes. Adding a Sitemap directive helps search engines discover and index all your important pages. Format: Sitemap: https://example.com/sitemap.xml
How does this tool fetch my robots.txt?▾
Our servers fetch the robots.txt file from the root of your domain (e.g., example.com/robots.txt) and parse it to identify rules, user-agent blocks, and potential issues.
What is a user-agent directive?▾
The User-agent directive specifies which crawlers a set of rules applies to. "User-agent: *" applies to all bots, while "User-agent: Googlebot" targets only Google's crawler.
Can I validate robots.txt for private sites?▾
No. The tool can only access publicly available robots.txt files. If your site is behind a firewall or requires authentication, the file cannot be retrieved.
