Google has been mobile-first since 2019, but most small business websites still load like it is 2014. If your mobile PageSpeed is under 70, you are losing rankings, traffic, and conversions to competitors who took it seriously.
What Core Web Vitals actually measure
- LCP (Largest Contentful Paint) — when the biggest visible element loads. Target: under 2.5s.
- INP (Interaction to Next Paint) — how fast the page responds to a tap. Target: under 200ms.
- CLS (Cumulative Layout Shift) — how much the page jumps as it loads. Target: under 0.1.
Why speed equals rankings
Google measures real-user data through the Chrome User Experience Report. Sites that fail Core Web Vitals get a soft demotion in mobile search — even if their content is excellent. Sites that pass get a quiet boost in competitive niches.
The five fastest fixes
- Compress hero images to WebP under 150KB. This alone often jumps PageSpeed by 20+ points.
- Lazy-load below-the-fold images. Use
loading="lazy"and explicit width/height. - Defer non-critical JavaScript. Move chat widgets, analytics, and third-party scripts to async/defer.
- Preconnect to fonts. Add
<link rel="preconnect">for Google Fonts in the head. - Reserve image and embed dimensions to eliminate layout shift.
How to test your own site
Run PageSpeed Insights on your homepage and a deep service page. Mobile is the score that matters. Anything under 70 is a problem.
