What is rel="nofollow" attribute? 502 Administrator Thu, May 13, 2010 Web Development 0 3547 The rel="nofollow" attribute of an tag is a hint to all the major search engines that this link should not be counted when calculating search engine ranking. In practise it means either that the link is user-generated, such as blog comments, thus may be spam or not approved by the page owner, or that I do not like or approve of the contents of the page that I am linking to.
