My site has disappeared from search?

Never have this problem, it's new domain, have 5-6 unique articles, old maybe 40 days. Maybe I'm push links a little hard but it's various links with different anchors. Site was at 5 page of Google search for main keyword and before 12 days site disappeared from search, I can't find it but it's still indexed. What I should do? Thanks

It's probably just dancing. Happens to new sites when linkbuilding is done.

Yeah I read about Google Dance but still it's too long, almost two weeks. :/

I think your website has hit by Google Panda, you should building backlink for your site.
