hi my competitor is having link from these kind of sites, i am really fed up to see it look like a network. but actually i can say its not private one, because it has several posting per day, and lots of posts. it look like any publicBN , What you think?? what it can be? if public one, can you name it?? should i go for review keywords or not?? because review keywords are only like 800- 1500 searches, if anyone is ranking for any review keyword. can you tell me is it profitable for 800- 1500 searches? and what its normal range of income??
