A robots. txt file tells search engine crawlers which URLs the crawler can access on your site. This is used mainly to avoid overloading your site with requests; it is not a mechanism for keeping a web page out of Google. To keep a web page out of Google, block indexing with noindex or password-protect the page.

A robots. txt file is used to prevent search engines from crawling your site. Use noindex if you want to prevent content from appearing in search results. This report is available only for properties at the domain level.

A robots.txt file lives at the root of your site. So, for site www.example.com , the robots.txt file lives at www.example.com/robots.txt .

While using this file can prevent pages from appearing in search engine results, it does not secure websites against attackers. On the contrary, it can unintentionally help them: robots. txt is publicly accessible, and by adding your sensitive page paths to it, you are showing their locations to potential attackers.
