Faceted navigation
Faceted navigation is a filtering interface that lets users narrow a collection by combining attributes such as category, size, color, price or availability.
What it means
Filters are often encoded as query parameters or path segments, and every combination can become a separate URL. A small useful catalog can therefore expose millions of permutations, reordered parameters, duplicates and empty-result pages unless generation and crawl rules are deliberate.
Why it matters
Well-designed facets help shoppers reach relevant products and can support selected landing pages. Unbounded combinations consume server resources, slow discovery and fill reporting with pages that have no distinct search purpose.
Example
Allow crawlable links for reviewed combinations such as `/running-shoes/women/`, but stop generating links for arbitrary price-sort-color permutations. Normalize parameter order, return 404 for nonsensical or empty combinations and keep the unfiltered category reachable.
Common mistakes
Do not block all filters before identifying valuable landing pages, expose every possible combination or redirect empty results to a generic category. Avoid relying only on canonical tags to prevent a crawler from requesting an infinite space.
How AYSA handles this
Signals reviewed
Facet combinations, result counts, parameter order, crawlable links, canonical and robots behavior
Problem AYSA can identify
AYSA can identify exploding filter patterns, duplicate permutations and empty-result URLs still exposed through site links.
Recommendation prepared
The plan lists combinations to retain, patterns to stop linking and any scoped canonical, robots or 404 behavior.
Approval preview
The user reviews useful and wasteful examples, estimated pattern size and potential merchandising impact before approval.
Execution
AYSA can adjust supported WordPress links and metadata; commerce-filter logic and routing usually require the platform or development team.
Verification
AYSA recrawls filter paths, tests invalid combinations and confirms that retained landing pages and controls match the approved matrix.
Limits
Inventory changes can alter result sets, and AYSA cannot guarantee immediate changes in external crawl allocation.

Quick answers
Frequently asked questions
Should every faceted URL be blocked from crawling?
No. Some reviewed combinations can be useful landing pages. The correct policy separates those from redundant, empty or combinatorial variants.
