Audit your faceted navigation to enumerate every URL pattern generated by filter combinations (color, size, price range, brand) and estimate the total indexable URL count
Apply rel=canonical from each filtered URL back to the base category page for filter combinations that do not represent distinct user intents worth indexing
Add a robots meta noindex tag to filter URLs that have very low search demand or that duplicate content already covered by other indexed pages
Block high-cardinality parameter patterns in robots.txt to prevent Googlebot from crawling the full combinatorial space when the pages should not be indexed at all
Use Search Console's URL Parameters tool (if available for your property) to tell Google how specific parameters affect page content and should be handled
Known gotchas
rel=canonical is a hint, not a directive; Google may ignore canonicals on faceted pages if it determines the filtered URL has meaningfully unique content or substantial inbound links; verify canonical signals are being honored in the Coverage report
Blocking faceted URLs in robots.txt prevents crawling but does not deindex pages that are already indexed; pair robots.txt blocking with a noindex meta tag on already-indexed pages by first temporarily allowing crawl, then recrawling
Some faceted URL combinations have genuine search demand (e.g., 'red running shoes size 10'); indiscriminately blocking all filters can eliminate ranking opportunities, so keyword research should guide which filter combinations to preserve as indexable
