Largest contentful paint is how long the biggest thing on screen takes to show up.
Usually that biggest thing is your hero image or headline. Google wants it visible within 2.5 seconds. Past 4 seconds is a fail.
Heavy hero images, slow fonts and scripts that run before the page draws all push this number up. Fixing it means shrinking the image and getting out of its way.
A Think Bright page draws its hero early because there is little in front of it. One measured rebuild, a Houston printer, saw its largest paint arrive 4.7 seconds sooner.
Core Web Vitals are Google's three measures of how a page feels to a real visitor.
Lighthouse is Google's free tool that scores a page from 0 to 100 on performance, accessibility, best practices and SEO.
The hero is the large top section of a page with the main headline, image and button.
Lazy loading waits to download an image until the visitor scrolls near it.
