How to use robots.txt to prevent AI crawlers from scraping sensitive data?

To prevent AI crawlers from scraping sensitive data, you can configure the robots.txt file in the website's root directory. The core is to set access prohibition rules for the User-Agent of AI crawlers. First, identify the User-Agent identifier of the target AI crawler. Common AI scraping tools typically include specific identifiers in the request headers, such as "GPTBot" and "ClaudeBot". The specific name can be obtained through server logs or crawler identification tools. Second, write rules in robots.txt: first specify the target User-Agent (e.g., "User-agent: GPTBot"), then use "Disallow: /sensitive-data-path/" to explicitly prohibit access to directories or files, such as "Disallow: /internal-docs/" or "Disallow: /user-data.html". To block all AI crawlers that are not explicitly allowed, use "User-agent: *" combined with specific path restrictions. Finally, ensure the robots.txt file is placed in the website's root directory (e.g., https://example.com/robots.txt) and test the validity of the rules with tools. It is recommended to regularly check for updates to the User-Agent of AI crawlers and adjust the rules in a timely manner to cover newly emerging scraping tools.
