Filters
Allow facets to reduce the choice without trapping the visitor.
Filters only work well when product data is reliable and the facets shown fit the current search intent.
Contextual facets
A laptop query requires filters other than shoes or furniture.
Active filters
Make selected values visible and easy to delete individually.
Numbers
Use result numbers to send expectations before applying a filter.
Mobile
Limit deep modals and maintain visibility on active choices.
No dead ends
Prevent combinations that unnecessarily lead to zero-result searches or provide immediate recovery.
Analytics
Measure use per facet and remove fields that add hardly any value structurally.
