How a Robots.txt File Works

A robots.txt file is normally placed at the root of a website, such as https://example.com/robots.txt. It can provide instructions for compliant crawlers with directives such as User-agent, Allow, Disallow, and Sitemap.

How to Create a Robots.txt File

  1. Select the crawler or bot the rule should target.
  2. Choose a crawl-delay option only when appropriate for your crawler setup.
  3. Select common directories to disallow or enter one custom path per line.
  4. Add a complete XML sitemap URL when you want a Sitemap directive.
  5. Review the generated file, then copy or download it.

Disallow Paths and Custom Rules

Use root-relative paths such as /private/, /checkout/, or /admin/. Enter one path per line. Do not paste complete robots.txt directives such as User-agent: or Allow: into the custom path field.

Robots.txt and XML Sitemaps

An XML sitemap can be referenced with a complete URL such as https://example.com/sitemap.xml. A sitemap helps crawlers discover URLs, while robots.txt provides crawler-access rules. They serve different purposes and can be used together.

Important Robots.txt Considerations

Robots.txt is a crawler-access mechanism, not a security system. Do not use it to protect private information. Blocking a crawl does not guarantee that a URL will never appear in search results, and crawler behavior can vary by bot.

Robots.txt for Different Websites

For a business website, blog, portfolio, ecommerce site, or web application, rules should match the site's actual structure. Start with the minimum rules you need and review them before publishing.

Frequently Asked Questions

What is a robots.txt file?
A robots.txt file contains rules that can tell compliant crawlers which paths they may or may not access on a website.
How do I create a robots.txt file?

Can I add custom disallow paths?
Yes. Enter one website path per line, such as /private/ or /checkout/.
