So i have recently taken on a partner in working to promote 3 adsense sites based on 3 very competitive niches: insurance, loans, and debt The sites are Pr1, PR2, and PR4 to begin with and have been up for more than 2 years I believe, so we don't have to worry about sandbox. They used to make about 50 USD per day with average clicks about 1.35 or so ish, a little less on another. I guess the one PR 4 gets about 50-100 visitors per day with very little promotion. Our methods will be manual social bookmarking for all the pages slowly over the course of a couple months, article submission of every article on the websites, as well as link exchanges from other related niche sites, high PR. Lastly we will be purchasing most likely outsourcing directory submissions of PR5+ directories related to our niches. I was wondering if there is anything else we can do to help us break into this niche even just a little, what am I missing?
