I was just searching through some UK based blogs today in google.co.uk and infact I was searching for pages based in uk. I suddenly came across a wordpress blog, You may know free wordpress blog which they provide that wordpress.com. I want to know how that page really appeared there? wordpress is hosted in US. I was just wondering. any possible answers? thanks
Location of hosting is just one factor that contributes to google's knowledge of where to geo-target. For a wordpress hosted blog I would think backlinks from UK sites would be the main clues that were being used.
geographic location is simply a search factor. don't assume that it's going to determine everything you see. I see american websites all the time in google.co.uk - it all depends on how well the content matches the search.
