Comments welcome on whether you are seeing a change in the default search order when you do searches. I've been hearing that eBay has begun testing it on eBay.com to show results by "Best Match" instead of by "Time ending soonest."
We've been talking about this since the summer - the Tamebay blog said eBay was testing this very thing in France in three categories.
The current default orders are very objective ("Time ending soonest" for search results and "Newly listed" for browse results). With Best Match, eBay is favoring sellers based on PowerSeller status and seller performance (most likely, Detailed Seller Ratings).
Whether you think this is unfair to sellers or a better experience for buyers, users have complained about not being able to find what they are looking at with the Best Match sort. Of course, user can always use the pull-down box to change the sort order, but this is not something all shoppers would do, and adds an extra step.
