How to Fix Largest Contentful Paint (LCP) Issues in Core Web Vitals

Introduction
Have you ever clicked on a website and left within seconds because it took forever to load? Chances are, that site failed the Largest Contentful Paint (LCP) test—a crucial part of Google’s Core Web Vitals. LCP measures how quickly the largest visible content element (like an image, video, or text block) loads on a page.
Google recommends keeping your LCP under 2.5 seconds. Anything beyond that can tank your SEO rankings, user experience, and conversions. In this blog, we’ll break down exactly how to fix LCP issues, explore FAQs, and share actionable strategies that even big brands use to stay ahead.

What Is Largest Contentful Paint (LCP)?
In simple terms, LCP is the time it takes for the main content of a webpage to load and become visible to users. It could be:
A hero image
A video thumbnail
A headline text block
A background image
If these elements load slowly, visitors won’t stick around. According to Google, 53% of users abandon a site if it takes more than 3 seconds to load. That’s why optimizing LCP is non-negotiable. Optimize your website’s core web vitals

How to Fix LCP Issues in Core Web Vitals
Here are 7 proven ways to improve your LCP score and keep your website lightning-fast:

1. Optimize Images (The Usual Culprit) Compress large images without losing quality (use WebP or AVIF). Implement responsive images with srcset. Use a Content Delivery Network (CDN) to serve images faster. 👉 Fun fact: Optimizing images alone can reduce LCP time by 30–40%.
2. Improve Server Response Time Use fast hosting or switch to a dedicated server. Cache assets with CDNs like Cloudflare. Minimize Time to First Byte (TTFB).
3. Use Lazy Loading Smartly Delay loading of off-screen images and videos. But ensure above-the-fold content (like the hero section) is preloaded.
4. Preload Important Resources Preload hero images using . Preconnect to important domains. Prioritize critical CSS and fonts.
5. Minify and Optimize CSS/JS Remove unused CSS. Split large JS files into smaller chunks. Load non-critical scripts asynchronously.
6. Reduce Render-Blocking Resources Inline critical CSS. Defer JavaScript where possible. Use Google PageSpeed Insights to identify blocking files.
7. Monitor and Test Regularly Use Lighthouse, PageSpeed Insights, or GTmetrix. Test on real devices—desktop, mobile, and low-end devices. Continuously monitor with Google Search Console → Core Web Vitals report.

Frequently Asked Questions About Fixing LCP

1. What is a good LCP score?
   Google considers anything under 2.5 seconds as good. Between 2.5–4 seconds is “needs improvement,” and above 4 seconds is poor.

2. Does LCP affect SEO directly?
   Yes. Since May 2021, Core Web Vitals, including LCP, are ranking factors. A poor LCP can drag down your search visibility.

3. What causes slow LCP?
   Unoptimized images
   Slow server response
   Render-blocking CSS/JS
   Poor mobile optimization

4. How fast can LCP improvements show results?
   Once fixes are live and Google re-indexes your site, you may see ranking improvements in 4–6 weeks.

5. Do Core Web Vitals only matter for mobile?
   No. While mobile experience is critical, LCP is measured on both desktop and mobile. However, mobile tends to have more LCP issues due to weaker networks and devices.
