WebmasterWorld administrator, engine, feels Bing has upped the weighting of local domains and how well they rank in the localized version of Bing search. He posted this at WebmasterWorld saying:
When using bing uk i'm noticing uk domains getting prominence over generally better ranked and better linked .com, despite being hosted in the uk.
So I used my umbrella query and tested Bing US vs Bing UK and I saw the same thing. Here are those results:
|Bing US||Bing UK|
Have you noticed this?
