Some months ago Google changed the way that treats the nofollowed links. This new policy causes massive problems to all the sites that use the nofollow attribute as it affects the way that PageRank flows in the site and it could lead to PR loss.
WebSEOAnalytics has developed a free script that allows you not only to do PageRank sculpting as easily as you did before but also keep all the rel=?nofollow? links you have in your sites.
Brief description
Our solution uses obfuscated javascript in order to block Google. Additionally we encode the URLs in order to make sure that they can not be detected by search engines. This script has already tested in several sites for the last 3 months and it is currently used in this site.
The main idea is that the developer will still be able use rel=?nofollow? to block the links he wants. Then a script will detect all the nofollowed links and it will replace it with the obfuscated javascript.
