WP Rocket vs LiteSpeed Cache: passed Core Web Vitals, +14% organic

WP Rocket vs LiteSpeed Cache: passed Core Web Vitals, +14% organic

WP site was failing Core Web Vitals on 70% of URLs. We tested both caching plugins on identical clones.

WP Rocket ($59/yr single site)
👍 Sensible defaults — turned it on, INP and LCP improved with near-zero config
👎 Paid only, and it works best on standard Apache/Nginx, not LiteSpeed servers

LiteSpeed Cache (Free, needs LiteSpeed/OpenLiteSpeed server)
👍 Free, with server-level caching + QUIC.cloud CDN; fastest results when the host runs LiteSpeed
👎 Configuration is a maze; wrong settings broke layout twice in testing

On a LiteSpeed host, LiteSpeed Cache won and cost $0. CWV 'good' URLs went 30% → 92%, and over the next 10 weeks organic traffic rose ~14% as Google rewarded the pass.

Verdict: Pick WP Rocket for easy wins on any host, LiteSpeed Cache if your server supports it and you'll tune.

Best for: WP Rocket = set-and-forget owners; LiteSpeed = tinkerers on LiteSpeed hosting.
