do you agree my strategy every day 1-2 post + social bookmarking + directory submit without forum profile and comment post
Hmm what has posting to do with rankings ? No i don't agree ... And for home page main site you don't build links ? Have your strategy gotten first page ranking ?
It's not a very good strategy. You will build something but very slowly over a long period of time. You could stand to do a bit more posting and directory submission if that's where you want to focus.
first day 1-2 post + social bookmarking + directory submit second day 1-2 post + social bookmarking + forum profile third day 1-2 post + social bookmarking + comment post and again first day
