## Article

Core Web Vitals are three measurements Google uses to describe how a page feels to real visitors. They are worth understanding because they track things your customers notice: whether the page appears quickly, responds when tapped and stays still while they read.

### Largest Contentful Paint (LCP): loading

LCP measures how long it takes for the largest visible element, usually a hero image or headline, to appear. Google considers **2.5 seconds or less** good.

Common causes of slow LCP: very large images, slow servers, render-blocking scripts and fonts, and hero images that load late because they are added by JavaScript.

### Interaction to Next Paint (INP): responsiveness

INP measures how quickly the page responds visually after someone clicks, taps or types. Good is **200 milliseconds or less**. INP replaced the older First Input Delay metric in 2024.

Poor INP usually comes from too much JavaScript running at once: heavy themes, page builders, chat widgets and tracking scripts competing for the browser's attention.

### Cumulative Layout Shift (CLS): visual stability

CLS measures how much content moves around while the page loads, the frustrating jump that makes you tap the wrong button. Good is **0.1 or less**.

Typical causes: images and embeds without reserved space, banners injected at the top of the page, and fonts that change size when they load.

### How Google measures them

The assessment is based on real visitors' data, looking at the 75th percentile of page loads over the previous 28 days. A page that feels fast on your office computer may still struggle on mid-range phones over mobile data.

### Practical fixes

- Compress and resize images, use modern formats and give images explicit dimensions.
- Load the main image early instead of lazy-loading it.
- Remove scripts you don't need and delay non-essential ones.
- Reserve space for embeds, ads and banners.
- Choose hosting that serves pages quickly, ideally through a CDN.

### Treat it as ongoing

New plugins, tracking codes and content can undo improvements. Check the Search Console report monthly.

## Questions

### Do Core Web Vitals affect rankings?

They are part of Google's page experience signals. Relevance and content quality matter far more, but a fast, stable site helps both rankings and conversions.

### Where can I see my Core Web Vitals?

Google Search Console has a Core Web Vitals report based on real-user data, and PageSpeed Insights shows both real-user and lab measurements for individual pages.
