Core Web Vitals are three metrics Google uses to measure how well your site feels to a real user: how fast it loads, how quickly it responds and how stable the layout stays. They matter for SEO, but even more for how many visitors stay on the page instead of closing the tab. In essence, they are human-perceived speed expressed in numbers.
The three metrics, simply
- LCP — how long the main element takes to appear (usually the big image or headline). Aim for under 2.5 seconds.
- INP — how quickly the page reacts to an action, such as a click or tap. Aim for under 200 ms.
- CLS — how much content "jumps" while loading. Aim for close to zero, so nobody taps by mistake.
Why it matters for business
A slow site loses visitors before they see the offer, and Google favors fast pages when ranking results. For users in Moldova, many on mobile connections, every extra second means lost requests. Studies show the bounce rate rises sharply with each second of waiting. Speed isn't a technical whim — it's money tied directly to sales and to your position in search. Beyond that, a fast site makes a first impression of professionalism: a visitor instinctively feels that a business which looks after its site looks after its customers too. Slowness signals the exact opposite, even when your offer is excellent.
How to improve them
For LCP: compress images, use modern formats and fast hosting with a CDN close to your users. For INP: cut heavy scripts, defer anything non-essential and load only what's needed at startup. For CLS: reserve space ahead of time for images, banners and fonts so they don't push content around after the visitor starts reading. Most issues come from unoptimized images and too much code running for no reason.
How to measure them
Use PageSpeed Insights or the Core Web Vitals report in Google Search Console. There you see real-user data, not just a lab test, and exactly which pages need attention. Start with your most visited pages, where improvement brings the biggest gain, and measure again after each change to confirm the progress.
