I just heard about this new attribute added on links but really don’t have any idea about it. Thanks goodness to Dave Taylor that explains what is nofollow and it’s advantage on SEO.

By adding this attribute rel on your anchor/link,  search engine will ignore the linked site w/c gains page rank from the source site.

It’s done like this:
<a href=”some URL“ rel=”nofollow”>text that’s linked</a>
