Core Web Vitals are a set of specific factors that Google considers important in determining the overall user experience of a webpage. They include metrics such as loading speed, interactivity, and visual stability. For example, if a website takes too long to load or has elements that shift unexpectedly during loading, it may result in a poor Core Web Vitals score.

The three key metrics that constitute Google Core Web Vitals :

1. Largest Contentful Paint (LCP): LCP measures the loading performance of a web page by identifying the time it takes for the largest content element, such as an image or text block, to become visible to the user. A fast LCP ensures that users can access the main content of a page quickly, leading to a positive user experience.
2. First Input Delay (FID): FID assesses the interactivity of a web page by measuring the delay between a user’s first interaction, such as clicking a button or tapping a link, and the browser’s response to that action. A low FID indicates that the page is responsive and allows users to interact with it without delays or interruptions.
3. Cumulative Layout Shift (CLS): CLS evaluates the visual stability of a web page by quantifying the amount of unexpected layout shifts that occur during the page’s loading process. These shifts can occur when elements on the page, such as images or ads, dynamically change their position, causing frustration for users who may inadvertently click on the wrong elements. Minimizing CLS ensures that the page layout remains stable, providing a seamless browsing experience.

Google Core Web Vitals have become a significant ranking factor in Google’s search algorithm, particularly for mobile search results. Websites that prioritize optimizing their performance based on these vitals are more likely to rank higher in search results and attract more organic traffic.

How to improve Core Web Vitals Score?

To improve Core Web Vitals scores, website owners and developers can implement various optimization techniques, such as optimizing image sizes, reducing server response times, and minimizing render-blocking resources. By prioritizing user-centric performance improvements, websites can enhance their overall user experience and achieve better visibility in search engine results.
