Frequently Asked Questions
How does page speed affect SEO?
Page speed is a direct Google ranking factor through Core Web Vitals. It also indirectly affects SEO through bounce rate — 40% of users abandon pages loading over 3 seconds, sending negative engagement signals to Google. A 1-second delay reduces conversions by 7%.
What are Core Web Vitals?
Core Web Vitals are three Google metrics measuring user experience: LCP (Largest Contentful Paint — loading speed, threshold: under 2.5s), INP (Interaction to Next Paint — responsiveness, threshold: under 200ms), and CLS (Cumulative Layout Shift — visual stability, threshold: under 0.1). Only 33% of major sites currently pass all three.
Is mobile or desktop page speed more important for SEO?
Google uses mobile-first indexing, so mobile page speed is the primary ranking signal. Average mobile load times are 15–27% slower than desktop due to network and device constraints. Mobile optimization is the higher priority for most sites.
