SEO guide
A practical editorial view on when category, geo, facet, listing, profile, and request pages deserve to be indexed.
Category, geo, profile, and guide pages should only be indexed when they have enough live supply, useful context, and unique value for a searcher. Being technically renderable is not the same as being worth crawling.
Most sort combinations, empty facets, and internal search states should not become public index targets. Crawl budget is won by discipline, not by generating every possible URL.
Strong marketplaces define index, noindex, canonical, redirect, and removal behavior up front. They also review weak pages regularly instead of waiting for rankings to collapse.
