Google has made it official: how your website feels to real users affects how it ranks. It measures this through Core Web Vitals, a set of metrics that sound technical but describe something simple: does your page load fast, respond quickly, and stay stable while it loads? Here is what they mean in plain language.
The three Core Web Vitals
There are three metrics at the heart of it:
- Largest Contentful Paint (LCP), how quickly the main content loads. Fast is under 2.5 seconds.
- Interaction to Next Paint (INP), how quickly the page responds when a user interacts. Lower is better.
- Cumulative Layout Shift (CLS), how much the page jumps around as it loads. Less movement is better.
Why Google cares
Google’s business depends on sending people to pages they will have a good experience on. A page that loads slowly, lags when tapped, or shifts content under your finger creates a poor experience, so Google is less likely to rank it highly. Core Web Vitals are how that experience gets measured at scale.
How they affect your business
The impact is twofold. Directly, poor vitals can suppress your rankings. Indirectly, the same problems that hurt your vitals, slow loads, instability, also drive users away and kill conversions. Fixing them improves both visibility and revenue, as we cover in why website speed costs you customers.
How to improve them
The practical fixes overlap heavily with general performance work: optimise and properly size images, reduce and defer heavy scripts, reserve space for elements so the layout does not shift, and build on fast, well-configured hosting.

The bottom line
Core Web Vitals turn “good user experience” into something measurable, and something Google rewards. Treat them as a business priority, not a developer afterthought. Layer 8 builds performance into SEO from the ground up →
