If you have a website, you probably want it to load fast and rank well on Google.
One important factor that affects both speed and SEO is something called Largest Contentful Paint, or LCP for short. But what exactly is LCP? And why should you care about it?
In this article, we will break down what Largest Contentful Paint means, how it works, and how it impacts your website’s SEO and user experience. Plus, we’ll share some tips on how to improve your LCP score so your visitors stay happy and your site ranks higher!
What Is Largest Contentful Paint?
Largest Contentful Paint is a web performance metric that measures how long it takes for the largest visible content element on your web page to load. This could be an image, a video, or a big block of text. Essentially, LCP tells you when the main part of your page becomes visible to users.
Imagine you visit a website, and you see a big hero image or a headline; LCP measures how fast that big visible element loads. The faster it appears, the better the experience for your visitors because they feel like the page is ready for them to interact with.
Why Does Largest Contentful Paint Matter?
- Measures Page Load Speed: Largest Contentful Paint shows how fast the main content on your page appears to visitors.
- Enhances User Experience: A faster LCP makes your website feel more responsive and keeps users happy.
- Important SEO Ranking Factor: Google includes LCP as part of its Core Web Vitals, affecting your search rankings.
- Reduces Bounce Rates: When pages load quickly, visitors are less likely to leave immediately, increasing engagement.
- Boosts Organic Traffic: Improving your LCP can help your site rank higher, attracting more visitors from search engines.
What Is a Good Largest Contentful Paint Score?

Google suggests that a good LCP score is 2.5 seconds or less. If your LCP is under this time, your page loads quickly and offers a good experience.
If your LCP score is between 2.5 and 4 seconds, your page needs some improvement. Above 4 seconds is considered poor and can hurt both your user experience and your search rankings.
It’s important to aim for that 2.5-second mark to keep visitors engaged, increase your SEO visibility, and give your site the best chance to rank well.
What Factors Affect Largest Contentful Paint?
Several things can slow down your LCP score. Here are some common factors:
- Large Images: Big, unoptimized images take longer to load and can delay the largest visible content.
- Slow Server Response: If your server takes a long time to respond, it delays everything else on the page.
- Render-Blocking Resources: Scripts and stylesheets that block the browser from displaying content quickly can affect LCP.
- Heavy JavaScript: Too much JavaScript or slow scripts can delay when the content appears.
- Client-Side Rendering: Websites that rely heavily on JavaScript to render content on the user’s browser may load slower, hurting LCP.
How Does Largest Contentful Paint Impact SEO
Largest Contentful Paint is part of Google’s Core Web Vitals, which influence your website’s ranking in search results. Google wants to show users pages that load fast and offer a great user experience. If your LCP is slow, Google may rank your site lower compared to competitors with faster loading times.
Also, slow LCP can increase bounce rates because visitors get impatient and leave your site. Higher bounce rates can signal to Google that your content isn’t satisfying visitors, further hurting SEO.
So, improving LCP not only makes users happy but also helps your site perform better in search engines.
How To Improve Largest Contentful Paint

Improving your LCP score involves several strategies that focus on speeding up the loading of your largest content on-page SEO elements. Here are some easy tips:
Optimize Images
Images are often the largest content on a page. Make sure your images are compressed without losing quality. Use modern formats like WebP that load faster and serve images in the right size for different devices.
Use Fast Hosting and CDN
Your server’s speed affects how fast content loads. Choose a reliable hosting provider and use a Content Delivery Network (CDN) to serve content faster by delivering it from servers close to your visitors.
Minimize Render-Blocking Resources
Scripts and stylesheets that block rendering slow down your page. Minimize CSS and JavaScript files and defer non-essential scripts to speed up rendering.
Implement Server-Side Rendering or Static Site Generation
With headless websites, pages are often built using JavaScript. The problem? Search engines sometimes struggle to read those pages. That’s where SSR or SSG comes in; they make sure your pages are already complete before being shown to users or search engines.
This means Google can easily crawl and understand your content, helping you show up in search results. Tools like Next.js make it easy to set this up, so your site is fast and SEO-friendly from the start.
Use Lazy Loading Wisely
Lazy loading is a good best practice for image SEO that delays loading images and videos until they are needed. This can help reduce initial load times but be careful not to lazy load the largest visible content, as that will hurt your LCP.
Reduce JavaScript Execution Time
Heavy JavaScript slows down page rendering. Audit your JavaScript and remove any unnecessary code or split it into smaller chunks so the browser can handle it faster.
Preload Important Resources
Preloading tells the browser to load critical files like fonts or images earlier in the process, speeding up when the largest content appears.
