Kas ir Core Web Vitals?

Core Web Vitals are Google's three page experience metrics: Largest Contentful Paint (LCP) for loading, good under 2.5 seconds; Interaction to Next Paint (INP) for responsiveness to input, good under 200 milliseconds; and Cumulative Layout Shift (CLS) for visual stability, good under 0.1. Google measures them from real Chrome users and uses them as a ranking signal.

Keep the ranking weight in perspective: vitals are a minor factor that mostly matters as a tiebreaker between comparable pages, and passing them will not rescue weak content. Their larger value is direct, since slow and janky pages lose visitors regardless of Google; sluggish landing pages show up as worse bounce and conversion rates. One measurement subtlety: lab tools like Lighthouse simulate a load, while rankings use field data from real users in the CrUX dataset, and the two frequently disagree. Trust field data, visible in Search Console's Core Web Vitals report.

Typical fixes: compress and properly size images, reserve space for ads and embeds to stop layout shift, cut render-blocking scripts, and use a CDN.
