How to prevent search engines from indexing a single page of my website?

Question

I don\'t want the search engines to index my imprint page. How could I do that?

Answer 1

Just include this line in your tag. Why I'm telling you this because if you use robots.txt file to hide your URLs that might be login pages or other protected URLs that you won't show to someone else or search engines.

What I can do is just accessing the robots.txt file directly from your website and can see which URLs you have are secret. Then what is the logic behind this robots.txt file?

The good way is to include the meta tag from above and keep yourself safe from anyone.
