1) The author conducted an experiment with two identical websites, one receiving nofollow links and the other receiving follow links, to test the impact of nofollow links on SEO. 2) Over the course of a year, the website receiving nofollow links consistently outperformed the one receiving follow links in visibility and page 1 keyword rankings. 3) This experiment provides evidence that nofollow links still have value for SEO and can help with website rankings, despite common beliefs that they provide little SEO benefit. The author advocates reporting on and optimizing for nofollow links.
