Hide a Page from Search Results
The Site Search enables your visitors to quickly and easily discover the content they want on your site. But what about pages and content you'd rather not have show up on the search results -- how can you hide it?
Every page has a "Hide from Search Results" setting; here's how to access it: Go to the Pages tab and select the page you'd like to hide. Then click the Advanced Settings link.
This will open up a dialog box with several page settings; the one you're looking for is at the very bottom: "Hide this page from search engines." Check that box and click Save Settings.
After you make this change you'll need to Publish the site again to fully hide the page and its content on your live site.
