Low site rank-need help

HI,
i have my site “ittl.ir” its started about 6 month ago but my site rank in world in 15 000,000th of world site ranks
but my freind site"vplus.ir" started with me and his site rank is 6 000,000 of site rank of world, why its happened,i update my site every week with 7 post but my freind site is offline about 2 month!!!

i dont know whats wrong,google webmaster didnt message for banning or some thing like it but last message of googlewebmaster was about dont permission to wpincloude files,that i edited robots.txt and i allowed this acces too.

but no success yet,
could you analyze my site and tell whats wrong its my site link www.ittl.ir
