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.

There is no law stating that /robots. txt must be obeyed, nor does it constitute a binding contract between site owner and user, but having a /robots. txt can be relevant in legal cases. Obviously, IANAL, and if you need legal advice, obtain professional services from a qualified lawyer.

To fix this log into Blogger and go to Settings > Crawlers and Indexing > Enable custom robots. txt, The switch should be ticked OFF and a new robots. txt file will be generated with the correct parameters. There is no reason to do a custom robots.

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.
