Why page speed is an SEO factor

Google uses page experience signals—including Core Web Vitals (LCP, INP, CLS)—as ranking factors. Faster pages improve conversion rates, reduce bounce, and allow more efficient crawling. Even small improvements on high-traffic templates can move the needle.

LCP

Largest Contentful Paint – how quickly the main content becomes visible. Aim under 2.5 s.

INP

Interaction to Next Paint – responsiveness to user input. Aim under 200 ms.

CLS

Cumulative Layout Shift – visual stability. Aim under 0.1.

Frequently asked questions

Lab vs field data?

Lab data (simulated) is useful for debugging. Field data (CrUX) reflects real users and is what Google primarily uses for ranking.

Mobile or desktop first?

Google primarily uses mobile scores for mobile-first indexing. Optimize for mobile, then refine desktop.

How often should I re-test?

After any significant front-end or hosting change, and at least monthly for key templates.
