How to Improve Your Largest Contentful Paint for Intermediate and Expert Developers
Blog post from New Relic
Largest Contentful Paint (LCP) is a metric introduced by Google to assess how quickly the main content of a webpage is visible to users, playing a significant role in Google's algorithm and thus impacting web performance and customer experience. LCP measures when the largest element, such as an image or block of text, is rendered in the viewport, excluding elements outside the viewport and background images. Tools like Google Search Console, WebPageTest, and Chrome DevTools' Lighthouse can measure LCP, but New Relic offers a more robust solution by capturing LCP metrics with its browser agent, taking into account intricacies like user interaction and providing detailed insights into performance bottlenecks. Improving LCP involves optimizing load times, reducing resource load delays, and ensuring efficient server performance. As LCP becomes more critical for user retention and search engine visibility, New Relic's monitoring capabilities allow teams to benchmark and enhance their website's LCP, ensuring a better user experience and potentially improving search engine rankings.
