I often wonder why people get so worried about gaming Google and chasing page rank. At the end of the day, if your site is good, and you build up a following and a community and you interact with people out there on the net then people will find your site. If the content is worth anything then word will spread. Page rank, traffic, SEO, whatever, it will allow follow if you have something to offer.
But for those who want to learn more about page rank, it’s all been published, why not read up about it rather than continuously guessing what its all about. There is plenty of info in the official Google blogs too. They actually are very helpful when it comes to helping people build good sites.
I just get surprised time and time again when I see offers to share the secrets of google ranking success for x hundred pounds. There is nothing you can buy that hasn’t already been discussed on a zillion free blogs before!
