Practical guide to optimizing Core Web Vitals: improve LCP with CDN edge caching and next/image priority, reduce INP by breaking long tasks with scheduler.yield(), and eliminate CLS with proper sizing.
Core Web Vitals are a set of metrics defined by Google to measure the real-world user experience of web pages, covering loading performance (LCP), interactivity (INP), and visual stability (CLS).
To improve LCP, prioritize critical resources, use next/image with priority for hero images, and leverage CDN edge caching to reduce time-to-first-byte.
For INP optimization, break up long tasks using scheduler.yield(), avoid blocking the main thread with heavy JavaScript, and defer non-critical scripts.
To minimize CLS, always specify width and height for images and embeds, avoid inserting content above existing content, and use CSS transform for animations instead of layout-triggering properties.
Regular monitoring with tools like Google Search Console, PageSpeed Insights, and Lighthouse helps track your Core Web Vitals score over time and identify regressions early.
