Hi, firstly sorry for my english if i have so mistakes! lets say that i have 50k auto-approve blog list on unique domains, and i want use this to post comments, for one site/few keywords... What politic will be the best? like post 1000 comments/day ... maybe 100 comments/day, next day 200 comments and increase this number? If i have keyword for example "seo" then use i should use only "seo" as anchor text or "seo tips", "seo help" will be better? 500k backlinks on 50k unique domains will be boost site for specified keywords?
