eBay Search on Mobile

On mobile we found the use of the refinement controls, in previous design, when hidden behind a single ‘refine’ button, led to frequent keyword requiring by the user, the process wasn’t as good or as quick as the site experience.

We went about introducing a search refinement carousel control, that ranked the top refinement for search query, in order to prompt the use of filtering and encourage the use of structured data (where the quality of items returned is far higher).

 
The control produced an enormous lift in refinement usage, user feedback was positive and the engagement allowed the ranking of refinements to be greatly improved over time.
