Caching Core Web Vitals WordPress

Membership Website Core Web Vitals Recovery

The membership site was suffering from slow logged-out performance, heavy scripts, and poor interaction timing. I improved caching, reduced third-party script impact, cleaned up assets, and optimised key templates.

How it happened

Members log in every day — but Google and every prospect only ever see the logged-out site.

The public pages were the slowest ones

Members saw a working site every day — but Google and every prospective member landed on logged-out pages scoring 36, waiting over six seconds for content and 530ms for anything to respond under a pile of heavy scripts.

Caching for the visitors who matter most

Logged-out traffic got real caching, third-party scripts were cut back to what the site actually needs, and the key templates were optimised — 22 requests gone and page weight down 55%, while the members’ logged-in experience stayed untouched.

Vitals recovered across the board

Mobile 36 → 92, desktop 72 → 98. LCP from 6.1s to 1.7s and interaction latency from 530ms to 118ms — failing Core Web Vitals turned passing on every page a prospect ever sees.
