Crawler rules generator
Robots.txt Generator
Build a standards-friendly robots.txt file with user-agent groups, allow and disallow rules, crawl delay, and sitemap directives.
Tool guide
What is the Robots.txt Generator?
The Robots.txt Generator builds a plain-text robots file from selected user-agent, Allow, Disallow, crawl-delay, and sitemap settings. It is designed to reduce syntax mistakes and give you a file that can be copied or downloaded for deployment at the website root.
Robots rules can affect how search engines crawl the entire site, so generated output must be reviewed before publishing. Blocking a folder does not protect it from unauthorized access and does not always remove its URLs from search results.

Step-by-step
How to use the Robots.txt Generator
- 1Enter the website origin
Use the preferred HTTPS hostname without a page path.
- 2Add crawl rules
List only the paths that should be allowed or disallowed for the selected user-agent.
- 3Generate and inspect
Read the output carefully, especially broad rules containing a single slash.
- 4Deploy and test
Upload the file as /robots.txt, confirm it returns text/plain, and test important URLs.
Interpretation
How to understand the results
- Disallow: / blocks crawling for the matching user-agent and should be used only intentionally.
- An empty Disallow value does not block the site.
- The Sitemap line helps discovery but does not replace sitemap submission or validation.
Practical advice
SEO best practices
- Start with the simplest file that meets the real crawl-control need.
- Do not publish staging-site blocking rules on the production domain.
- Use authentication for private data instead of relying on robots.txt.
- Keep essential CSS, JavaScript, and image resources crawlable.
- Review the file after CMS, directory, or hostname changes.
Before you act
Limitations of this automated check
The generator cannot know your application routes or which paths are safe to block. Crawler support for nonstandard directives varies. The file is public and voluntary; malicious bots can ignore it. Always test the deployed file against important URLs.

Common questions
Robots.txt Generator FAQs
Can robots.txt secure an admin area?
No. Use authentication and authorization. Robots.txt publicly reveals paths and compliant crawling rules only.
Should I block search-result pages?
It depends on the site and crawl strategy. Review canonicalization, internal links, and whether the pages provide unique value.
Where do I upload the file?
At the root of the exact host, for example https://example.com/robots.txt.
Can I create separate rules for different bots?
Yes. Add separate user-agent groups, but make sure their rules do not accidentally conflict or duplicate broader groups.
