My site is not listed on google anymore

Hi, mi site created on 2009 is not listed on GOOGLE anymore, I have hire some guys for SEO in the past, link building, I was on the first/second pages for some some keywords

I am not an expert on SEO but I think those guys do white SEO

Now I have nothing!, anyone can help me to analyze my situation, why this is happening!

My site: voxfiles .com

You want some traffic to your site, aren't you ?

is this site a wp site or a stander site?
