"Recent changes in the processing of the nofollow attribute have caused consternation and concern among many publishers. Let's talk about what has happened, and how you should adapt your SEO strategy accordingly. A Little History PageRank sculpting has been a hot topic since 2007. This was the idea that you could control, at a granular level, the flow of link juice in your Web site through the use of the nofollow attribute. The concept can be illustrated by this chart: ... Impact of the Change Based on this, it may make sense to remove any onsite nofollows you have. For example, if you nofollow all the links to your "About Us" page, the link juice in those links is discarded. If you let the links pass juice, your About Us page will be able to pass some of that juice back into the site through the links contained on it. If you want to be cautious about this, carefully check out the results of removing the nofollows. Monitoring the impact of every SEO change you make is always a good idea. While I believe that Google is serious about their new stance, theory (or position) and practice don't always align in the world of search. Also, while Google announced a new policy, Yahoo and Microsoft haven't commented on this. More aggressive publishers will continue to sculpt by using older techniques for it. For example, you can use JavaScript that encodes the link so it isn't recognizable as a link by the search engines. Done aggressively, this will behave much the same way that nofollow did back in 2007 (because the search engine won't recognize the link as a link so no link juice is wasted on it). This is pretty aggressive stuff though. It's a bit like hanging a flag on your site and saying "I am aggressively optimizing for search engines." It might fit well for smaller sites that believe their overall visibility is low (I still wouldn't recommend it for those sites), but sites that have a fair amount of public visibility should stay away from it. Instead, use the natural link structure of your site to flow link juice (and your site visitors) where you want them to go. Creating the best possible user experience on your site is the best way for you to spend your time, as it will also make your site more attractive to potential linkers. " - Susan Beebe
