Page Speed
Quick definition
Page speed is how fast a webpage loads and becomes interactive — a key user experience signal and a confirmed (modest) Google ranking factor.
Modern page speed measurement focuses on Core Web Vitals — LCP, CLS, INP — along with traditional metrics like Time to First Byte (TTFB) and full page load.
Why Page Speed matters
Slow pages hurt conversions far more than they hurt rankings. Even a 1-second delay can reduce conversions by 5–10% across high-traffic SaaS funnels.
How Page Speed works in practice
Audit with Google PageSpeed Insights, GTmetrix, WebPageTest, and real-user monitoring tools (Calibre, SpeedCurve). Prioritize template-level wins that improve many pages at once.
