Hey Oliver, thanks so much for the kind words. Really glad you're digging the content.

Basically the current thinking in SEO circles is that link wheels, which consist of everything you do pointing to your money sites, leave too much of a footprint for the SERPS. What people are doing these days is more of a situation where you have a series of links to your money site, and then a huge array of zig zagging link patterns back to those sites. Meaning that out of 500 links or so, maybe only 100 of them are actually pointing at your money site and then the rest of them are pointing to your first tier links. But once more, the patterns are inconsistent and not every 2nd tier link is linking to every 1st tier link. It looks much more natural.

As for no follow links... there is a lot of evidence that the no follow tag means almost nothing anymore. I build links all the time using no-follow sites. Even affiliate links appear to help. I have heard from countless marketers who have run tests using nothing but no-follow sources and seen their sites climb in the rankings just as if the links were do-follow. So in short, while i think do-follow is better, I would not be afraid of no-follow links, and i think sites like Squidoo are still totally relevant for backlink purposes.
