Website performance has become an important factor in creating a successful online presence. A website may have excellent content and attractive design, but slow loading speed and poor user experience can negatively affect rankings and customer engagement.
Google introduced Core Web Vitals as a set of performance metrics that measure how users experience a website. These metrics help evaluate website loading speed, responsiveness and visual stability.
For businesses investing in SEO, understanding Core Web Vitals is essential because a better user experience can support improved search performance.
What Are Core Web Vitals?
Core Web Vitals are user experience metrics introduced by Google to measure important aspects of website performance.
The main Core Web Vitals include:
Largest Contentful Paint (LCP)
LCP measures how quickly the main content of a webpage loads.
A good LCP score indicates that users can access important content quickly.
Factors affecting LCP include:
- Large images
- Slow servers
- Unoptimized code
- Heavy scripts
Interaction to Next Paint (INP)
INP measures how quickly a website responds when users interact with it.
Examples include:
- Clicking buttons
- Opening menus
- Filling forms
A responsive website creates a smoother user experience.
Cumulative Layout Shift (CLS)
CLS measures unexpected movement of webpage elements during loading.
Poor layout stability can happen due to:
- Images without dimensions
- Dynamic advertisements
- Changing page elements
A stable website improves user satisfaction.
