Why blog speed decides rankings
Google measures page experience through Core Web Vitals, and slow pages lose twice: directly through the ranking signal, and indirectly because readers bounce before the content loads. Every 100ms of delay measurably cuts engagement, and between two comparable articles, the faster one wins the tie.
Speed also gates crawling. Fast pages get crawled more often and indexed faster, which compounds across every post you publish. Our Core Web Vitals guide covers the fixes in detail.
Reading your score
90-100: fast. Google and readers are happy. 50-89: needs work. You are losing engagement and giving faster competitors an edge. 0-49: slow. Speed is actively suppressing your content.
Test the mobile score first: it is measured on simulated mid-range hardware over 4G, which is how Google evaluates your site and how most first-time readers arrive. Most WordPress blogs land between 40 and 70 on mobile. Superblog blogs score 90+ because pages ship as pre-built static HTML from a CDN, with images auto-converted to WebP.
