Performance
Advanced caching, compression, and optimisation for lightning-fast WordPress sites
Overview
ProRank SEO's Performance is a comprehensive solution for optimising your WordPress site's speed and performance. It combines origin page caching, background cache warming, compression, CDN integration, resource hints, and guarded asset optimisation without pretending WordPress can enable server-level protocols.

Server & Browser Delivery
ProRank supplies safe browser resource hints and reports what your web server or CDN actually provides. HTTP/3 and interim 103 responses must be enabled at the server or CDN layer.
- Detects Brotli and HTTP/3 advertisement from your origin or CDN
- Does not fabricate HTTP/3, server-push, or interim response headers from PHP
- Resource hints (preload, prefetch, preconnect)

Troubleshooting
Cache not working?
- • Check if you're logged in (cache is disabled for logged-in users by default)
- • Verify your server supports the required PHP extensions
- • Check for conflicts with other caching plugins
- • Enable debug mode in ProRank SEO → Settings → Advanced to view detailed logs
Brotli not compressing?
ProRank automatically falls back to gzip compression if your server doesn't support Brotli. Check the response headers for X-ProRank-Compression to see which method is being used.
