Core Web Vitals are Google’s measurements of how your website feels to use: how fast it shows content, how quickly it responds to taps, and whether things jump around while loading. They affect your rankings — and, more importantly, your sales.
The Three Metrics, in Plain English
- LCP (Largest Contentful Paint): how long until the main content appears. Target: under 2.5 seconds.
- INP (Interaction to Next Paint): how quickly the page reacts when someone taps or clicks. Target: under 200ms.
- CLS (Cumulative Layout Shift): how much content jumps around while loading (the reason you tap the wrong button). Target: under 0.1.
Why You Should Care Beyond SEO
Every extra second of load time measurably increases abandonment — studies consistently show conversion drops of 5–10% per second. Speed isn’t a technical vanity metric; it’s revenue.

Run your homepage through PageSpeed Insights (free, by Google). Green means healthy; orange or red means you’re losing rankings and customers to faster competitors.
The Fixes That Move the Needle
- Compress and resize images — the #1 cause of slow LCP. Use WebP format.
- Good hosting — a slow server caps everything else.
- Remove bloat — every plugin, tracker and animation library costs milliseconds.
- Set image dimensions — reserves space so content doesn’t jump (fixes CLS).
- Cache and compress — serve returning visitors instantly.
When to Rebuild Instead of Patch
If your site is on a heavy, plugin-stacked theme and every fix moves the score two points, rebuilding on a lean foundation is usually cheaper than the endless patching — and every site we build passes Core Web Vitals from day one.
