A quality user experience is essential for a site's success in the long run, and Web Vitals help measure this experience. Google has identified three Core Web Vitals: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics quantify a visitor's experience with page loading speed, browser responsiveness, and visual stability. Optimizing these vitals improves the site's SEO performance and user engagement. Google provides various tools to measure and improve Core Web Vitals, including Lighthouse, PageSpeed Insights, Chrome User Experience Report API, and Search Console. Additionally, techniques like caching, preloading resources, compressing data, avoiding layout shifts, and using transform animations can enhance page loading speed and stability. Using a headless CMS like Strapi provides complete control over the app's presentation, allowing for flexibility in tweaking the user experience as necessary. By focusing on Core Web Vitals, developers can create websites that provide an improved user experience, stand out from competitors, and attract positive search engine rankings.
