I am trying out a new project, in which I plan to do the majority of my own SEO. First of all, I thought I could find some high PR blogs to post on. I have used scrape box, and have found a ton of relevant <PR3 blogs to post on. The question is, what sort of content should I be posting? Where and what should I make the anchor text back to my site? Should I be writing the content myself, or just spinning content? I know that spinned content can be used for link lasts and what not, but for manual high pr relevant blogs im assuming all the content i post should be written manually? thanks!
