Hi, How can i set up nofollow tags using robots.txt file??? And do all SE's take notice of this in the robots.txt? Thanks
There is nothing you have to do with robots.txt file, no follow tag is used with a tag for e.g <a href="http://yahoo.com" rel="nofollow">yahoo</a> Good luck
Maybe it's not exactly notfollow, but you can look how the others do it http://www.whitehouse.gov/robots.txt
following are different combinations that can be in meta tag <meta name="robots" content="index,follow"> <meta name="robots" content="noindex,follow"> <meta name="robots" content="index,nofollow"> <meta name="robots" content="noindex,nofollow">
