Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) is the Core Web Vital that measures how long it takes for the largest visible element of your page to be loaded and painted. It is therefore purely about loading speed: how fast does the visitor see the main content appear on screen.

What exactly does LCP measure?

LCP looks at the largest element within the visible screen during loading, usually a hero image, a large video poster or a block of heading text. The moment that element is fully painted is your LCP score. Google considers an LCP under 2.5 seconds good, between 2.5 and 4 seconds moderate, and anything above that poor. It is therefore not about the page fully loading, but about the moment the visitor gets the feeling that something is there.

How do you improve your LCP?

The biggest gain often lies in images. Compress your hero image, deliver it in a modern format and give it priority in the loading process. A CDN brings your files closer to the visitor and speeds up delivery. Set lazy-loading so that you specifically do not defer the LCP element, because that slows down your score. Furthermore, a fast server response and limiting blocking scripts also help. LCP is, together with CLS and INP, one of the three Core Web Vitals Google pays attention to.

Why this matters for your growth

At Customer Impact, speed is not about a nice figure in a testing tool, but about visitors who stay and convert. A slow page speed leaves opportunities on the table precisely in B2B, because a decision-maker who drops off before your proposition comes into view will never become a customer. A fast LCP is therefore not a technical detail, but a direct lever on your revenue.
