Faceted Navigation (Filters)
Macro-semantics (site level)Faceted Navigation (Filters) is a filter system on e-commerce sites (color, size, price, material) generating dynamic URLs. Requires careful configuration to avoid wasting crawl budget on thousands of URLs.
Faceted navigation is an alternative to mega menus: deeper attributes (material: wooden, metal) land in sidebar filters instead of main navigation. Breadcrumbs reflect hierarchy: Furniture > Outdoor > Rattan. Faceted navigation is connected to cascading clustering — each filter corresponds to an entity attribute from the EAV model.
In practice, use canonical URLs and noindex for filter combinations that don't have search volume — otherwise you'll generate thousands of 'empty' URLs that eat crawl budget. Only filters with volume >500 should have indexable URLs. In the case of an outdoor furniture store, sidebar filters replaced mega menu, slimming down HTML and freeing crawl budget for content.
