What are Core Web Vitals?

Core Web Vitals are a set of three measurements Google uses to judge how a web page feels to someone using it. They are part of Google's page experience signals, and they focus on three things a visitor notices right away: how fast the main content appears, how quickly the page responds to a tap or click, and whether the layout jumps around while loading.

The three metrics are:

• Largest Contentful Paint (LCP) measures how long it takes for the biggest visible element, usually a hero image or a large block of text, to render.
• Interaction to Next Paint (INP) measures how quickly the page responds after a user interacts with it, such as tapping a menu or submitting a form.
• Cumulative Layout Shift (CLS) measures how much visible content moves unexpectedly while the page loads.

These numbers are collected from real visits (field data) and are checked against thresholds that Google publishes for good, needs improvement, and poor performance. Sites that clear the thresholds are in a better position to meet Google's page experience expectations, though strong content and relevance still matter more for ranking.

Why it matters: in Malaysia, many shoppers and readers browse on mid-range Android phones over mobile data, so a slow or jumpy page costs real visits. Core Web Vitals give site owners a shared, measurable way to spot those problems. Technical SEO specialists in the technical SEO category are the usual people who audit and fix them.
