After 2 months gogole dance, my site is back.
I want to share my experiences during it.
I bought lots of links, that caused google dance. Now I'm higher on serps for my primary keywords, but lower on main keywords.
I mean:
blue shoes -> was 10th, now 4th
grey shoes -> was at 13th, now 7th
but;
shoes -> was at 60th, now 110th
etc.
It took my 2 months with zero income, lots of money for links, lots of depression, even thought to find 9-5 job, but little difference at total. So I think bulk linking is not worh for the risk. It still may work for some, but as you see it comes with a big risk. It was my only income source.
Advices at here were continue to building links. But as I finished all my budget all once 2 months ago, I wasn't able to continue to build links.
Thanks to all friends replied the thread to help me. I believe that if my site come back, any site can come back.
