David Eaves reports that UK based users who go to yahoo.com are now being redirected from the .com version to the Yahoo UK domain.
David said this is brand new behavior from Yahoo. 24 hours earlier, if a UK internet user went to Yahoo.com, it would keep them on Yahoo.com. Now, Yahoo is sending UK users off to Yahoo UK.
I honestly have a feeling this has to do with Yahoo Now Showing Geo-Location Under Search Ads from two days ago. Yahoo told me that they rolled out that feature last "week with the roll out of a new “geo labels” feature." I would not be surprised if the same geo-technology was applied to this.
I am going to post screen captures of this at Search Engine Land, with the behavior of how Yahoo, Google and Live handle UK users.
