Creating non-searchable pages

I'm new to Drupal, so bear with me. Formerly working in another CMS, Ektron, I had the ability to make landing pages unsearchable by clicking a button. In this way I could clone a content page, give it a new url alies that I could use for ads or give to prospects in an email, and those people would go to that page. The page functioned exactly like the original page which shows up on the site and is searchable, but the cloned page is not visible on the public site and wouldn't come up if you searched for it. You could only get to the cloned page by putting the url in your browser or clicking a link of the url. All of the functionality on the cloned page worked like the original page. The only difference is that it was not accessible from the main website. Is there any way to create such unsearchable pages in drupal?
