Understanding Directives

  • User-agent: Specifies which bot the rule applies to (e.g., Googlebot for Google, * for everyone).
  • Disallow: Tells the bot NOT to visit a specific folder or page (e.g., /admin/ or /private-files/).
  • Allow: Used to grant access to a sub-folder within a disallowed parent folder.
  • Sitemap: Tells bots exactly where to find your Sitemap XML file to index your content faster.

Why block AI bots? Many publishers now choose to block crawlers like GPTBot (OpenAI) or CCBot (CommonCrawl) to prevent their content from being used to train Large Language Models (LLMs) without permission. Our tool makes this easy with a single click.

Frequently Asked Questions

How do I block ChatGPT (GPTBot)?

You need to disallow the specific user-agent `GPTBot`. Our generator has a preset for this. The rule looks like: `User-agent: GPTBot` `Disallow: /`

Where do I upload the robots.txt file?

It must be placed in the **root directory** of your website (e.g., `https://your-site.com/robots.txt`). If you place it in a subdirectory, search engines will not find it.

What does the asterisk (*) mean?

The asterisk is a wildcard. When used as `User-agent: *`, it applies the rule to **all** robots/crawlers. When used in a path like `/*.pdf`, it matches any file ending in .pdf.

What is Crawl Delay?

It tells bots to wait a certain number of seconds between requests to avoid overloading your server. Note: Googlebot ignores this directive, but Bing and Yandex respect it.
