My site falls more than 50 in two days, help me!

[WebMaster021]

My site appeared in the top 10 for that link (http://www.vipgoldrj.com/paginas/ensaios.html) and not by this (http://www.vipgoldrj.com), was well at 2 months, and he suddenly disappeared, I wanted to know if he had been penalized and Google told me it was not. What should I do?

The. Sorry my English, I am Brazilian and I'm using Google translator.

Warning from SEOmoz staff: this is an escort site with full frontal nudity and is not safe for most workplaces.

What keyword was that for? Has anything changed with your site architecture? New website? Are the pages still followed (nofollow, noindex, etc) A little more information will allow me to help you more

[WebMaster021]

Keywords: Escorts, Girls Program, Program RJ Girls, Girls Program in Rio de Janeiro. And one day the site dropped from page 1 to 54
The site is about SEO and fell a lot. I do not know what to do.

1. Verify your site in Google Webmaster Tools and check for warnings.

2. paginas/ensaios.html is mostly images, with very little text. Hard to rank with no content.

3. paginas/ensaios.html also has hidden text (black text on a black background) which is against Google's guidelines.
