Largest Contentful Paint (LCP).
How long it takes for the main content of your page to appear. Google cares a lot about this number.
LCP measures the time from page request to when the largest visible element (usually a hero image or headline) finishes rendering. Google considers anything under 2.5 seconds "good," 2.5 to 4.0 seconds "needs improvement," and over 4.0 seconds "poor."
On a typical small-business site, LCP is killed by a too-large hero image and render-blocking JavaScript. The fix is almost always: serve a properly-sized, modern-format hero (WebP under 200 KB), preload it, and defer non-critical scripts.
LCP is one of three Core Web Vitals · the others are CLS (layout shift) and INP (interaction lag).
Pairs with these.
- Core Web Vitals (CWV)Google's three-number summary of how fast and stable your website actually feels.
- LighthouseGoogle's open-source tool that grades a webpage on speed, accessibility, SEO, and best practices.
- Cumulative Layout Shift (CLS)A score for how much content jumps around as your page loads. Lower is better.
