Why this matters
Returning 404 for empty filter pages prevents indexation of thin, content-less pages that dilute site authority.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Identify filter combinations yielding zero results.
- Configure server to return 404 status code instead of 200 for these URLs.
- For temporary empty results, serve 200 with user-friendly messages.
- Test HTTP response with developer tools or HTTP clients.
- Monitor analytics to avoid user confusion from 404 pages.
Watch for
Use 200 status with helpful messages instead of 404 for temporary out-of-stock pages to maintain user experience.
Definition of done
Faceted URL queries returning no visible product results respond with 404 HTTP status confirmed via header inspection.
