Robots.txt Builder
Build robots.txt content with user-agent, allow, disallow, crawl-delay, and sitemap directives.
Robots.txt Builder
Use this Robots.txt Builder to create crawler rules with User-agent, Disallow, Allow, Crawl-delay, and Sitemap directives. It is useful for SEO checks, static site launches, staging environments, documentation sites, and quick crawler-control drafts.
The tool turns separate fields into a complete robots.txt file that can be reviewed and copied into a public site root.
What This Tool Does
The builder helps create common robots.txt directives:
- Set the target user-agent
- Add disallowed paths
- Add explicitly allowed paths
- Add crawl-delay when a crawler supports it
- Add one or more sitemap URLs
- Copy the generated robots.txt output
Why Robots.txt Files Matter
The robots.txt file tells crawlers which parts of a website should or should not be requested. It can help keep admin pages, internal routes, duplicate pages, and generated paths out of crawler workflows.
It is not a security control. Private data should be protected with authentication, not hidden by robots.txt rules.
Common Use Cases
- Creating a starter robots.txt file for a new website
- Blocking crawler access to admin or internal paths
- Adding sitemap URLs for search engines
- Drafting staging-site crawler rules
- Reviewing allow and disallow paths before deployment
Example
User-agent: *
Disallow: /admin
Allow: /admin/help
Sitemap: https://example.com/sitemap.xml
Notes for Developers
- Robots.txt must be available at the site root
- Rules are public and can be viewed by anyone
- Different crawlers may interpret unsupported directives differently
- Use canonical tags, noindex headers, and authentication where appropriate
- Always test important SEO rules before relying on them
