I just read this article Google Big Daddy SearchQuake About to Rumble Your Ranking? By Mike Banks Valentine (c) 2006 in SiteProNews The discussion centres around a client who was getting different rankings than his SEO was reporting in their ranking report. The rankings the client was getting were higher than the SEO. The SEO explained: "Google has (at last count) nine data centres which serve up search results and that they were getting results from a data center in the Eastern US which showed differing results from results shown to us here in California." It is rumoured that there are about 60 data centres scattered all around the world using more than 100,000 computers. The reason you see website rankings and page rank changes is due to the fact that the results are switching back and forth between an updated and an old data center. Things usually stabilise after a few days but its best to just ride it out and trust that it will settle down. I am not sure how many data centres there are in the UK but it seems that the only time Google shows different results is when there is an update in progress. When it eventually settles down then the index is the same on the related data centres. The difference between the google.com and google.co.uk results is due to Google presenting more relevant results to the different market places. Things like UK hosting and .co.uk inbound links and a myriad of other factors would help Google to determine relevancy. Good luck with the impending "rumble". |
