Page Speed measures the time from request to interactive, quantified by the three Core Web Vitals (LCP / INP / CLS). Mobile thresholds are stricter — on 3G, LCP should be ≤4s; each extra second adds ~7% to bounce rate.

What is Page Speed?
Page Speed measures the time from request to interactive, quantified by the three Core Web Vitals (LCP / INP / CLS). Mobile thresholds are stricter — on 3G, LCP should be ≤4s; each extra second adds ~7% to bounce rate.
How do you apply it in practice?
Checklist: HTTP/3, Brotli, webp/avif images, font subsetting, JS code-splitting, CDN edge caching.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Page Speed" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

Core Web Vitals
Core Web Vitals are Google's three UX performance metrics: LCP (Largest Contentful Paint ≤2.5s), INP (Interaction to Next Paint — Good ≤200ms / Needs Improvement 200-500ms / Poor >500ms), CLS (Cumulative Layout Shift ≤0.1). All three must be green to qualify as 'Good' and affect mobile ranking.
