Filter and sort controls that generate many URL combinations from a set of listings.
Faceted navigation lets users refine listings by attributes such as size, colour, price or brand, which is valuable for usability but can generate a near-infinite number of parameterised URLs. Left uncontrolled, it is a leading cause of crawl-budget waste, duplicate content and index bloat on e-commerce and directory sites. Managing it typically combines canonical tags, selective noindexing, robots controls and careful decisions about which valuable facet combinations to keep indexable.
