Is eBay Holding 25% of Your Listing Views Hostage?

1. The removal of the Choice policy gets rid of the restriction that
   has required sellers to list individual listings for each size, color
   or configuration of the same item.
2. The removal of the Multiple Listings Limit policy ends the 15-item
   rule that has governed how many identical listings a seller can have
   listed at the same time.

Starting this week, the display of multiple identical items from the same seller will be limited to one in Search results. An item is considered identical if it has the same title and the same listing format, and the listing chosen for display will be determined by the sort option that the buyer chooses. We will be rolling this out to all sort options by next week. When multiple auction-style listings with the same title have a different number of bids and different prices, these are no long considered identical and will all be displayed.

Also, the number of unique listings (listings for different items) per seller will be up to ten per page. In a case where a seller has a number of items—for instance 20—that could potentially show up in the same search results, 10 will be shown on the first page, and the other 10 will be on the second page. (These improvements go hand in hand with the removal of the Multiple Listings Limit policy.)
While the jury is still out on how this will effect shoppers and sellers on eBay, the test yeilds some interesting results. See the full story here: 25% of listings hidden on eBay.com : TameBay : eBay news blog and forum
