Hello,

After reading your question, I want to say that Google has released their two major algorithm update i.e. Hummingbird (27 September) and penguin 2.1 (4 October), I think your site has gone down because of these updates now I will give you its detail information about these updates:-

Hummingbird :-this update affects 90% of search result, this algorithm is all about to modify the searching query,Google said that its time to conversational search ,because of this update you need to pay more attention in SEO like

1)Your site should be well written
2)Avoid keyword stuffing
3)In your keyword you have to use conversational tone
4)Use social media
5)Built quality backlinks

Penguin 2.1 Update:-This update impact on 1% of web spam,this update penalize those site which have include the same anchor text link in their forum posting, and biography of forum, spamming blog commenting. If you had used spammy directories in past and your site's link are present on that directory site till present then you will also penalize.

How to recover:-

1)Remove all spammy links from your site
2)Create genuine and quality links
3)Use Social media

I hope it will worthy for you.

Thank you.

directories, social bookmarks, etc.. are spammy strategies. They hurt more than they help. If it is possible, try to get them removed and instead, try something else. For example guest posting etc.. to build ranking.
