There are times when you wouldn’t want Search Engines to index your web page, but how do you go about preventing it? There are a number of ways to make sure that your web page is not found by the search bots, using meta tags is one of them. Meta tags are tags that provide detailed instructions regarding the web page to the Search Engines.
To make sure that the particular web page is not indexed, use the “NOINDEX” meta-tag and to prevent bots from following links from the page, use the “NOFOLLOW” tag between the <HEAD> and </HEAD> tags of your HTML.
<META NAME="ROBOTS" CONTENT="NOINDEX,NOFOLLOW"> //This tag tells the robots not to index this page and not to follow any links within the page.
