原文外掛簡介
Cacheability makes your WordPress site a better HTTP citizen, improving SEO and cache efficiency.
Free Features
Soft 404 Fix
WordPress returns HTTP 200 for empty search results, invalid tag pages, and empty category archives. Google marks these as “soft 404” errors in Search Console, hurting your SEO.
Cacheability fixes this by returning proper 404 status codes when:
Search results are empty (/?s=nonexistent)
Tag archives are empty (/tag/nonexistent/)
Category archives are empty
Author archives are empty
Smart Cache-Control Headers
Automatically adds s-maxage headers so Varnish, NGINX, and CDNs can cache your pages efficiently without affecting browser caching behavior.
Search/404 pages: 1 hour cache
All other pages: 1 year cache (your purge plugin handles invalidation)
