Faceted Navigation
Faceted navigation is a filtering system — common on ecommerce and listing sites — that lets users narrow results by attributes like size, color, or price, typically generating a new URL (often with parameters) for each filter combination.

SEO Glossary
The core SEO problem with faceted navigation is combinatorial: a category with 5 filter types and 10 options each can generate thousands of unique URL combinations, most of which show near-duplicate content and have no meaningful independent search demand, creating a serious crawl-budget and index-bloat risk on large sites. Managing it typically involves deciding which filter combinations are worth being indexable (a genuinely popular combination like 'red running shoes' might deserve its own crawlable, optimized page) versus which should be blocked from indexing via robots.txt, noindex tags, or canonical tags pointing back to the unfiltered category page. This is a case where the technical decision has to be made deliberately upfront, since faceted navigation left unmanaged can quietly generate more low-value URLs than an entire site's worth of legitimate content.
Example
An ecommerce site with faceted navigation across size, color, brand, and price generates over 40,000 filter-combination URLs; only the dozen highest-demand combinations are left indexable, the rest are noindexed.
