Core Web Vitals are Google’s way of measuring real-world user experience: how fast your main content appears, how quickly the page responds to taps and clicks, and how stable the layout is while it loads. They are not the only ranking factor, but they align with what already makes visitors stay or leave.
Largest Contentful Paint (LCP) focuses on perceived load speed—often your hero image or headline block. Large unoptimized images, slow server response, or render-blocking scripts are common culprits. We typically address this with image sizing, caching, and lean critical CSS.
Interaction to Next Paint (INP) replaced First Input Delay as the responsiveness metric. If buttons and forms feel sluggish on mobile, INP suffers—hurting both rankings and form completions. Reducing JavaScript work on the main thread and deferring non-critical scripts usually helps.
Cumulative Layout Shift (CLS) measures visual stability. Ads, fonts, or late-loading embeds that push content around frustrate users and inflate CLS. Reserving space for media, setting dimensions on images, and avoiding injected banners without placeholders keeps layouts steady.
Investing in Core Web Vitals pays off beyond SEO: faster, calmer pages convert better on paid traffic too. If you’re planning a redesign, bake performance budgets into design and development from day one—not as an afterthought before launch.
