( but i think if all the site target only one keyword it will rank well for that keyword) 3)what are the best criteria to choose the mirconiche ? i found this : . the search per month must be between 1000 and 40 000 . . no more than 1.5millions results on google . hight competition keyword 4) i heared about some softawares building links , how does it work ? and it's really work ? 5) any advice ? thank u .
