https://support.google.com/webmasters/answer/93710?hl=en https://support.google.com/webmasters/answer/93710?hl=en > You can prevent a page from appearing in Google Search by including a noindex meta tag in the page's HTML code. When Googlebot next crawls that page, Googlebot will see the noindex meta tag and will drop that page entirely from Google Search results, regardless of whether other sites link to it. > Important! For the noindex meta tag to be effective, the page must not be blocked by a robots.txt file. If the page is blocked by a robots.txt file, the crawler will never see the noindex tag, and the page can still appear in search results, for example if other pages link to it.
