Hello guys. I have been into IM for few months now. Smartly backlinkig my webs and getting high pr for my low competition webs. I already have 5 small webs with pr3, but not satisfied with my rankings. All my websites are in a very low competition section. I do have exact match domains, yet can't to outrank other webs with pr0 or pr1. I've been reading a lot that quality content is THE key, yet i use spinned content for my webs, and i have never checked how unique they are after spinnig. I already make some money being in the 8-12 G spot, yet feel like i deserve to be higher with my pr3 webs. So, spun content could be the case? Maybe other in page seo things?
