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)
Cacheability Pro
Upgrade to Cacheability Pro for advanced features:
- Cache Warming — Automatically warm pages after purging so visitors never hit cold cache
- Conditional GET (304) — Return 304 Not Modified for unchanged content, saving bandwidth
- ESI Support — Cache pages with dynamic nonces (comments, login forms)
- Rate-Limit Safe — Smart request queuing to avoid 429 errors
- Sitemap Warming — Warm all pages from sitemap after full purge
- WP-CLI Commands —

FAQ
Is it compatible with caching plugins?
Yes! Cacheability works alongside any caching solution including WP Super Cache, W3 Total Cache, WP Rocket, Varnish, NGINX FastCGI cache, and CDNs like Cloudflare.
Does it slow down my site?
No. Cacheability adds minimal overhead — it just sets proper HTTP headers and status codes.
What’s the difference between free and Pro?
The free version fixes soft 404s and adds cache headers. Pro adds cache warming (automatically re-caches pages after purging), conditional GET responses (304), and ESI support for dynamic content.
Do I need Varnish HTTP Purge plugin?
For the free version, no. For Cacheability Pro’s cache warming feature, we recommend Varnish HTTP Purge or similar purge plugin.
