Closed or inactive listings redirect to a closed-listing page, not 404

Returning a 404 for a listing that existed and was indexed tells Google the URL is permanently gone with no context, which kills any inbound links and external citations built up over the listing's lifetime. Users who clicked a remembered link or a review site referral get a generic not-found page and assume the entire directory is broken. A dedicated closed-listing page preserves the URL for link equity, explains what happened, and offers alternatives (nearby listings, contact the business) that keep the session alive.

Check the listing status in the route handler and render a ListingClosed component with a 410 Gone status when the listing is closed or inactive. Keep the URL live so inbound links land on a meaningful page. Implement the branching in src/app/listings/[slug]/page.tsx and add visual treatment (muted colors, closed badge) that clearly distinguishes closed from active listings.

if (listing.status === 'closed' || listing.status === 'inactive') {
  return <ListingClosed listing={listing} suggestions={nearby} />
}

Set the response status to 410 in generateMetadata or a route segment config.
