I am not sure I understand what your social bookmark website is:
Is it an EXTERNAL site that you use to link TO your site (something like pintrest or something like that)?
Looking at your google impressions and clicks, it looks like you were hit with some kind of penalty.
...the problem is that all of my keywords, i mean the most of them have been disappeared from Google they were on the first page now they are gone.
That, too, is a sign of a penalty.
My blog have 6 month. i've checked my backlinks and everything is ok they still raising
I have to ask. How did you get your backlinks?
Did you buy any backlinks?
Have you used any website directories? Or article directories?
Have you been posting lots of comments in blogs and forums?
