Website speed and user experience have become major ranking factors in Google search results. In 2026, businesses in India are focusing more on website performance because users expect websites to load quickly and work smoothly on mobile devices. One of the most important concepts behind modern SEO performance is Core Web Vitals.
Core Web Vitals are a set of website performance metrics introduced by Google to measure real user experience. These metrics help Google understand whether a website is fast, stable, and user-friendly. Websites with poor Core Web Vitals may experience lower rankings, higher bounce rates, and reduced conversions.
This guide explains what Core Web Vitals are, why they matter, and how businesses can improve them for better SEO and website performance.
What Are Core Web Vitals?
Core Web Vitals are performance metrics used by Google to evaluate user experience on websites. They focus on loading speed, responsiveness, and visual stability.
The three main Core Web Vitals are:
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
- Cumulative Layout Shift (CLS)
1. Largest Contentful Paint (LCP)
LCP measures how quickly the main content of a page becomes visible to users.
A good LCP score means visitors can see important content quickly.

- Needs improvement: 2.5–4 seconds
- Poor: above 4 seconds
Common Causes of Poor LCP

2. Interaction to Next Paint (INP)
INP measures how quickly a website responds when users interact with it.
Examples include:
