What is the difference between FCP and LCP?

What is the difference between FCP and LCP?

FCP stands for First Contentful Paint, while LCP stands for Largest Contentful Paint. FCP measures when the first piece of content is rendered on the screen, whereas LCP measures when the largest piece of content is visible. Both are important for understanding user experience.

Why is LCP more important than FCP?

LCP is often considered more important because it reflects the loading performance of the main content of a page, which directly impacts user satisfaction. If users see the largest content element quickly, they are more likely to stay on the page.

How can I improve my LCP score?

To improve your LCP score, you can optimize images, use a content delivery network (CDN), and minimize render-blocking resources. Ensuring that your server responds quickly also helps.

Are there tools to measure FCP and LCP?

Yes, tools like Google PageSpeed Insights, Lighthouse, and WebPageTest can help you measure both FCP and LCP, providing insights on how to improve them.
