Website suddenly gone from SERP

[gunjanp]

Hi All,

I have one website skin-care-products-uk.co.uk. I have optimized it and it was ranking (1 to 10 most of) in google.co.uk on all keywords related to this site. It was ranking in Google since last 4 months.

But today when i checked the SERP for this site in google.co.uk, I found that it is not ranking in google.co.uk on any keywords. I can see this site only on the keywords of "skin care products uk" on 3rd page.

I have not use any BlackHat techniques for this site. And also I checked this site in
Webmaster tools that all pages of this site are crawling properly by the Googlebot, and also I could not find any error in my webmaster tools.

In our server sometimes we are getting request timed out. This problem in our server.
But due to this problem my ranking is gone, I don’t think so. Because my other websites are also on same server and they are ranking very well in Google.

I know that due to request timed out from server side we can lose our ranking, if Googlebot found 404 in our site. But in my webmaster tools I am not getting this kind of any error.

I don’t know what is the reason behind it why my website is gone from ranking on all keywords.

So please let me know, now what I have to do for getting my ranking back.

Thanks in Advance.
