Executive summary
Core Web Vitals measure real-world loading speed, responsiveness and visual stability. Google uses them as part of page experience signals, and poor scores directly hurt user experience regardless of SEO impact.
The direct answer
Core Web Vitals are three metrics: Largest Contentful Paint (loading speed), Interaction to Next Paint (responsiveness), and Cumulative Layout Shift (visual stability) — each with a "good" threshold Google uses as a page experience signal.
Step-by-step
01
Measure your current scores
Use PageSpeed Insights or Search Console’s Core Web Vitals report.
02
Optimize the largest above-the-fold element
Compress and properly size images or fonts driving LCP.
03
Reduce render-blocking resources
Defer non-critical CSS and JavaScript.
04
Reserve space for dynamic content
Ads, embeds and images should have set dimensions to avoid layout shift.
05
Re-test on real devices
Lab data and field data can differ; confirm improvements hold up.
Common mistakes
Only testing on desktop when most traffic is mobile.
Optimizing images but leaving unused JavaScript unminified.
Ignoring layout shift caused by late-loading ads or fonts.
Treating a single good PageSpeed score as the full picture.
Frequently asked questions
Did INP replace FID?
Yes — Interaction to Next Paint replaced First Input Delay as the responsiveness metric.
Are Core Web Vitals a direct ranking factor?
They’re part of Google’s page experience signals and can influence rankings, especially among otherwise similar pages.
What’s the fastest way to improve LCP?
Optimize and properly size your largest above-the-fold image or text block, and reduce render-blocking resources.
Key takeaways
- LCP, INP and CLS each measure a distinct part of real-world experience.
- Image optimization and reduced render-blocking scripts fix most LCP issues.
- Reserved space for dynamic elements prevents most CLS problems.
