Yep. You just need to create a text file called
robots.txt and put it in the root folder of your website. This file allows you to exclude certain URLs from search engines.
Basically, you just identify which robots you want to exclude (* wildcard for all) and then list the directories or files you want them to stay away from. Example:
Code:
User-agent: *
Disallow: /hiddenfolder/
Wikipedia shows some more examples.
