Mobile PageSpeed: 66 → 97.
Vladimir Shumilov
Mobile PageSpeed: 66 → 97. Same site. Same hosting. No redesign.
Here's what actually moved the score — on any CMS, in 2026:
Remove unused JavaScript and CSS. Most sites carry 50–70% of stylesheet rules that apply to nothing. Strip what isn't used, defer what isn't critical.
Convert images to AVIF. Not WebP. AVIF. 30–50% smaller at the same visual quality. Your LCP element is probably an image. This is the fastest single win.
Lazy load everything below the fold. One attribute. Measurable LCP improvement on almost every site.
Clean up font loading. Unused weights and character subsets add silent weight. Add font-display: swap to eliminate render-blocking.
Set proper cache headers. Static assets should be cached for at least a year. Most sites cache nothing or cache everything for 10 minutes. Both are wrong.
And one metric that matters more in 2026 than before: INP. Interaction to Next Paint is now a confirmed Google ranking signal. 43% of sites still fail the 200ms threshold.
Speed is not a luxury. It's infrastructure.
