What are Core Web Vitals
Core Web Vitals are a set of metrics introduced by Google to measure the quality of a website’s user experience. These parameters analyze fundamental aspects such as page loading speed, visual stability and interface responsiveness.
The goal of Core Web Vitals is to provide clear indicators of the real performance of a website, helping developers and website owners improve the overall quality of navigation.
Why Core Web Vitals are important for SEO
Google uses Core Web Vitals as one of the factors that contribute to evaluating the quality of a web page. A fast and stable website provides a better experience for users and has a higher chance of achieving better rankings in search results.
For this reason, optimizing Core Web Vitals does not only mean improving the technical performance of a website, but also increasing the chances of gaining greater visibility in search engines.
The three main Core Web Vitals metrics
Core Web Vitals are mainly based on three fundamental metrics that measure different aspects of the user experience during page loading and interaction.
LCP (Largest Contentful Paint)
Measures the time required to load the main element of the page. The lower this value is, the faster users perceive the content as loaded.
CLS (Cumulative Layout Shift)
Measures the visual stability of the page. A high value indicates that page elements move during loading, creating a negative user experience.
INP / Interaction responsiveness
Measures how quickly a page responds to user interactions such as clicks or input.

Improving Core Web Vitals requires optimization work that involves both the website code and the server infrastructure.
Among the most common improvements we find:
• image optimization
• reduction and minification of CSS and JavaScript
• use of caching systems
