Lost in google index

Dear all webmasters,
I want to ask you that my domain : sharpecontrast.com has lost index in google. Please help me by analyzing this domain, why google delete index from the site ?. I query using site:sharpecontrast.com and info:site:sharpecontrast.com result nothing.
I really need opinions from all webmasters here. please help me ...

Thank you in advance

 

when did this happen? did you do something to your site before losing the index?

 

Why there are double blogroll entries in source code?
That may trigger a penalty.

 

What did you do before this happens?Did you use any automatic submission tools.?

 

Same thing happened last week. one of my new blog was vanished after indexing. but i think you should not be tensed. cause my blog was re indexed after 4 days again. and its still indexed.
thanks

 

I did not do anything to this site, even i did not touch it while i was in long holiday for 2 weeks from 26 august 2011 to 10 Sept 2011.
Actually my three sites were deleted at once from googe index : sharpecontrast.*om, fkmad.*rg, planetsurf.*nfo.
This is the first experience for me. Please help me why those are deleted from google index ?

 

Build links that are genuine and are from high PR sites to your site. The de-indexing means that your site is in the Sandbox and Google will be looking at the links to your site if they are genuine or not, if they are spam then you could stay in the sandbox for quite some time.
