I cannot wrap my head around nofollow links. Of course I understand that it tells google to not count the link toward PR or whatever, but what I do not understand is why it might be beneficial at all. Sure, someone might click on the link and find the website, creating organic traffic, but that hardily counts for anything. Doing an internet search just gives vague reasons for why nofollow links are beneficial. And yet SER and Scrapebox blast them in the form of blog comments. So they must have a real purpose, or else they would not have this ability... right? Seriously, no BS, do nofollow links do anything?
