A robots.txt file tells search engine crawlers which pages or files they can or can’t access on your site. It’s placed in your website’s root directory and acts as a guide for web crawlers.

While not mandatory, a robots.txt file is recommended for most websites. It helps manage crawler traffic and protects sensitive areas of your site from being indexed.

The robots.txt file must be placed in your website’s root directory (e.g., https://example.com/robots.txt). Any other location will be ignored by crawlers.

Our tool supports all major search engine crawlers (Google, Bing, DuckDuckGo, Yandex), AI/LLM crawlers (GPTBot, Claude, etc.), and social media crawlers (Twitter, Facebook).

Common rules typically include:
– Blocking access to admin areas
– Protecting private content
– Managing AI crawler access
– Controlling access to development or staging environments

Use the LLM Crawlers section to add specific rules for GPTBot, Claude-Web, and other AI crawlers. Click “Add Common Rules” for preset AI crawler blocking rules.

Yes, you can block specific file types using patterns like:

  • Disallow: /*.pdf$
  • Disallow: /*.doc$

Add these rules individually using the “Add New Rule” button.

A properly configured robots.txt file can improve SEO by:
– Directing crawlers to important content
– Preventing indexing of duplicate or unnecessary pages
– Managing crawler resources efficiently

Update your robots.txt file when:
– Making significant website structure changes
– Adding new sections that need protection
– Changing your crawling preferences
– Implementing new security measures

The tool provides real-time preview of your robots.txt file. Review the output carefully before implementing. You can always modify the file later if needed.
