Slow pages lose visitors. Here is what Core Web Vitals measure and the simple changes that improve them.
What are Core Web Vitals?
Core Web Vitals are Google’s measures of how a page feels to use. They focus on three things.
- Largest Contentful Paint (LCP): how quickly the main content appears
- Interaction to Next Paint (INP): how quickly the page responds when someone taps or clicks
- Cumulative Layout Shift (CLS): how much the layout jumps around while loading
Why speed matters
Visitors on mobile networks leave slow pages quickly. Faster sites also tend to perform better in search because page experience is one of many signals search engines consider.
Practical ways to improve speed
Most speed problems come from a small set of causes.
- Resize and compress images, and use modern formats such as WebP
- Load images below the fold lazily
- Remove scripts and plugins you do not use
- Set width and height on images to prevent layout shifts
- Use fast hosting and caching
Measure before and after
Use tools such as PageSpeed Insights and the Core Web Vitals report in Google Search Console to see real-world results. If you would like a professional review, our web development team can audit and improve your site’s performance.
