After a good couple months of work, I have created a niche site with 130 SEO optimized, high quality 500-1000 word articles on a niche topic spanning hundreds of longtails following phpbuilt's guidelines. Currently, most of the pages are ranked 30-50 without any link building, done and the home/category pages are ranked 40, 54, 61, 71, 91 for the main 20k-110k monthly search keywords. . Since it's a potentially lucrative longterm keyword group ($1.5 cpcs with lots of longtails), I don't want to risk any heavy duty blackhat stuff for this site. How should I do SEO it to start getting some nice traffic trickling in? The home page has been bookmarked, and I put out a press release for the blog last week. I'm thinking of paying my VA to push out some high PR niche-related manual comments to each article and seeing how that goes.
