What is Largest Contentful Paint?
Definition
Largest Contentful Paint (LCP) measures the time it takes for the largest visible content element—typically a hero image, video, or large text block—to fully render on the screen.
Why It Matters
LCP is one of Google's three Core Web Vitals, directly impacting your search rankings. Studies show that pages with LCP under 2.5 seconds have 24% lower bounce rates. For ecommerce, every second of delay can reduce conversions by up to 7%.
How We Measure It
We use Google Lighthouse to test each store's homepage under simulated mobile conditions (4G network, mid-tier device). The LCP value represents the time from page request to when the largest element becomes visible.
