The "nofollow" Tag

Google has introduced a new link tag, and it's ultimately designed to tell the search engines to ignore the link when it comes to calculating their algorithm. This new link tag is called rel="nofollow" and it can be added to any typical href link. By adding the tag to a link on your site, you're telling the search engines to ignore it. According to Google, "From now on, when Google sees the attribute (rel="nofollow") on hyperlinks, those links won't get any credit when we rank websites in our search results."

Yahoo!, MSN Search, and other search engines are taking Google's lead and beginning to recognize this new link tag called the (rel="nofollow") tag.
