PageSpeed 90+ on WordPress: practical guide — FLYNTAQ Blog
How to bring WordPress to PageSpeed 90+ mobile. Critical CSS, images, caching, plugin audit.
The problem: slow WordPress
Average WordPress weighs 3-4MB with PageSpeed 30-50 mobile. 53% of mobile users abandon after 3 seconds.
The 5 steps
1. Plugin audit
Average WordPress has 47 plugins. Remove duplicates, find lighter alternatives.
2. Critical CSS
Inline above-the-fold CSS, defer everything else.
3. Images
WebP/AVIF, srcset, lazy loading on everything except the LCP image.
4. Multi-layer caching
OPcache → Redis → Page cache → Browser cache → CDN.
5. Fonts
Self-host, font-display: swap, preload, subset.
Typical results
PageSpeed 30-50 to 85-95 mobile. LCP from 4-8s to 1.5-2.5s.
