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
