nofollow backlinks
Nofollowing a link is adding rel="nofollow" inside of the link's anchor tag. Recently i published a post about how to identify dofollow backlink, many people have the idea but they dont really know what it mean.Setting the value of the "rel" attribute of a link to "nofollow" will tell Google that certain links on your site shouldn't be followed or pass your page's reputation to the pages linked to. the html tag will look like this example <a href="http://www.shadyseo.com/" rel="nofollow">shadyseo</a>. u can also learn more about it at shadyseo
