Core Web Vitals

Definition

Google's set of page experience metrics: Largest Contentful Paint (LCP) for loading speed, Cumulative Layout Shift (CLS) for visual stability, and Interaction to Next Paint (INP) for responsiveness. These are a confirmed Google ranking factor.

How Core Web Vitals works in practice

The three Core Web Vitals are Largest Contentful Paint (LCP: how fast the main content loads, target < 2.5s), Cumulative Layout Shift (CLS: how much the page shifts during load, target < 0.1), and Interaction to Next Paint (INP: responsiveness to user input, target < 200ms). Large unoptimised hero images and render-blocking JavaScript are the leading causes of poor LCP; ads, embeds, and dynamically injected content cause most CLS issues. Optimising Core Web Vitals requires collaboration between developers and marketers — developers address code performance while marketers audit third-party tag weight and ad formats loaded via GTM. Google Search Console provides a Core Web Vitals report segmented by URL group, device type, and connection speed, making it the primary diagnostic tool.

Why this matters

This term sits in the SEO category, which means it is most useful when evaluating organic search visibility, indexing, internal structure, and search intent. The goal is not to memorize the label. The goal is to know when it should change a decision, a page, a campaign, or a measurement setup.
