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.

Unblock the URLs: Identify the rules blocking the pages in the robots. txt file and remove or comment out those lines. Test the changes: Use Google's robots. txt Tester to test the changes and ensure that the pages you want indexed are no longer being blocked.

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.
