It seems search results are fluctuate. My site ranking still be the same when searched through Google DC's directly such as 66.102.9.99 or SEOChat keyword position tool, but when I do search on Google.com - Google.com (english) Local - Google.com (US based IP) My site ranking disappeared but allinanchor and allintitle and quote (" ") still be the same. It seems many sites got the same effect. Which one should I count on between 66.102.9.99 (or Google DC's) and Google.com?
