Core Web Vitals, explained for business owners.

Google measures how fast and stable your pages feel to real visitors. The names sound technical, but each one describes something your customers notice.

Core Web Vitals are measurements Google uses to judge how a page feels to the people using it. They are collected from real visitors, on their own phones and connections. Behind the acronyms are three simple questions.

Does the main content appear quickly?

This is Largest Contentful Paint: how long it takes for the biggest element, often a hero image or a headline, to appear. Heavy images, slow servers and too many scripts are the usual causes.

Does the page react when I tap?

Interaction to Next Paint measures how quickly the page responds when someone taps a button or opens a menu. Pages loaded with third-party scripts or heavy code tend to feel sluggish, especially on modest phones.

Does the page stay still?

Cumulative Layout Shift measures how much content jumps around while loading: the button that moves just as you tap it. Images without set dimensions, late banners and web fonts that swap are common causes.

Why it matters

These signals are part of how search engines assess pages, but the bigger reason is simpler: slow, jumpy pages lose visitors before they read a word. Many of your customers browse on mobile data, where every extra kilobyte counts.

Where to look

• Google Search Console shows which pages pass or fail, based on real visits.
• PageSpeed Insights tests a single page and suggests fixes.
• Fix templates first: one improvement can fix hundreds of pages at once.

Speed is not a technical detail. It is the first thing your visitors feel.
