As above, the website I did was the No1 in Google with keywords: Chinese Supermarket Edinburgh for about 10 days (18-28/July/2012), but it's gone to nowhere now? The google RP is 2/10 (didn't change) and traffic ranking is increasing. I have been advised by other forum it could be QDF: (query deserves freshness), but I don't think it's such complex.
Please don't suggest about cookies or in my google account.
I have opened new browser, for one I have used, I would clear cache, cookies and so on when doing a search test on google. (I nearly did it every time when I coded and tested web pages on serve.) Regarding to No1 in Google, I did the search in my neighbor's house, in my clients office. I don't want to look foolish if I told something not fully tested.
Any suggestions please.
