Reading Core Web Vitals
LCP — Largest Contentful Paint
Time for the largest element to render. Good: < 2.5s. Improve by compressing the hero image, using a CDN, removing render-blocking CSS/JS.
CLS — Cumulative Layout Shift
How much the layout "jumps" while loading. Good: < 0.1. Improve by setting fixed sizes for images and ads.
INP — Interaction to Next Paint
Response delay when users interact. Good: < 200ms. Improve by reducing heavy JavaScript.
What score is acceptable?
- 90–100: Good (green)
- 50–89: Needs improvement (orange)
- 0–49: Poor (red) — prioritize
What to optimize first?
The tool lists "improvement opportunities" with estimated time savings. Prioritize the ones that save the most — usually image optimization and removing render-blocking resources.
After optimizing, run a full SEO audit to check the other factors too.
Conclusion
Page speed is a worthwhile investment: good for SEO and conversions alike. Measure regularly and prioritize LCP for the biggest impact.
