The Camera & Photo category is a mixed-bag when it comes to the listing type the Best Match algorithm prefers for the various sub-categories.

According to my analysis, you should lean towards the fixed price listing type for the following sub-categories in order to have the best exposure in the Best Match search results:

  • Camera Accessories
  • Photo Albums, Display and Storage

You should stick with the auction-style listing format when posting in the following sub-categories:

  • Camera Parts & Repair
  • Darkroom & Developing
  • Film Cameras
  • Manuals, Guides & Books
  • Projection Equipment

 

As the chart below indicates, most of the sub-categories under Business & Industrial favor the auction-style listing under the the Best Match search algorithm.  The notable exception is the Packing & Shipping sub-category which provides a statistically significant boost to the fixed-price listing format.  The Fuel & Energy sub-category also seems to lean towards providing an advantage to the fixed-price listing format in the search results.

Review the methodology in the first post of this series.

According to my analysis, the book category and the sub-categories under it heavily favor the auction-style listings under the Best Match search algorithm.  This means that fixed-price listings in the book category are disadvantaged in the search results.  Sellers who list in the book category using Buy-It-Now listing format should reconsider if they want to be found at the top of the search results.

 

Things get interesting as we examine the Baby Category for the impacts of listing type (auction style or fixed-price) by category and sub-category under Best Match.

As a whole, the Baby category favors the fixed-price style listings, however the sub-categories vary widely - (three of them favor fixed-price style listings and three of them favor auction style listings).

The following sub-categories appear to favor auction style listings in the Best Match search results:

  • Baby > Bathing & Grooming
  • Baby > Keepsakes & Baby Announcements
  • Baby > Toys for Baby

The following sub-categories appear to favor fixed-priced listing styles under eBay’s Best Match search results:

  • Baby > Baby Gear
  • Baby > Feeding
  • Baby > Nursery Decor
