Every filter combination is a unique URL. All facet URLs are in the sitemap or linked. No canonical so Google indexes thousands of variants. Similar or duplicate content across facets. Crawlers follow every filter link and spend budget on low-value pages.

Common examples

A real-world example: after a site update, a business saw visibility drop for "Faceted navigation SEO". They checked Search Console, found the blocking issue, fixed it, and regained impressions over the following crawl cycles.

How to diagnose

Map facet URL patterns. Count how many URLs exist. Check if canonicals are set (usually to the main category). See if facet URLs are in sitemap or linked from key pages. Use Search Console to see how many are indexed.

Recommended fixes

Set canonical from facet URLs to the main category (or best representative URL). Noindex or disallow facet URLs in robots.txt if they add no unique value. Remove facet URLs from sitemap. Use JavaScript or nofollow for filter links if you don't want them crawled. Keep main category URLs as the primary targets.
