When it comes to website speed, what matters most is how fast users see the main content on your page. This is where Largest Contentful Paint (LCP) comes in. It measures how quickly the biggest visible element, like an image or heading, loads on the screen.
If LCP is slow, your website can feel slow, even if other parts are loading. This can make users leave early. In this guide, you’ll learn what LCP is, why it matters, and how to improve it in a simple way.
LCP tells you how quickly users see the main content on your page.
It only tracks what users can actually see first.
Even a fast-loading site can feel slow if key content is delayed.
Content at the top of the page affects LCP the most.
LCP can change depending on device and internet speed.
It reflects how fast your page feels, not just how it loads.

Largest Contentful Paint (LCP) is a way to measure how fast the main content of a page shows up on the screen. It looks at the largest image or text that users see first and tells you when the page feels ready to use.
A good LCP is 2.5 seconds or less. It can be affected by things like slow server speed, heavy files, or code that delays loading.
Many things can slow down your LCP score, especially anything that delays the main content from loading. Here are the key factors:
1. Slow server response time
If your server takes too long to respond, your page will load slowly. This can happen due to poor hosting, slow database queries, or delayed API responses.
2. Render-blocking JavaScript and CSS
Heavy JavaScript and CSS can stop the page from loading quickly. Too many plugins or complex designs can make this worse, especially for content at the top of the page.
3. Client-side rendering
When content is loaded using JavaScript in the browser, it takes extra time before users see anything. This delay can hurt your LCP score.
4. Slow-loading resources
Large images, videos, or unoptimized media take longer to load. If these appear at the top of the page, they can significantly slow down LCP.
Largest Contentful Paint (LCP) is important because it helps measure how fast users see the main content on your website. It is also a key part of Google’s Core Web Vitals, which means it can impact your search rankings. Here’s why it matters:
1. It affects your Google rankings
Google uses LCP as a ranking factor. A faster LCP can help your site rank better in search results.
2. It improves user experience
If your main content loads quickly, users stay longer. A slow LCP can make users leave your site early.
3. It impacts page performance
LCP shows how fast your page actually feels to users, not just when it starts loading.
4. It helps with better crawling and indexing
Faster pages are easier for search engines to crawl, which can improve your visibility.
5. It builds trust and engagement
When users see content quickly, they are more likely to interact, explore, and convert.
In simple terms, a good LCP means a faster, smoother, and more user-friendly website.
You can measure LCP in two ways:
1. Directly on the site. (field test)
2. Or through performance simulations performed by algorithms. (lab test)
Various tools speed up the work and make measurements more accurate for each of these methods. All of the tools suggested below are free and can help measure LCP scores for your web pages.
Field tools collect data from real users as they interact with your website in their natural environments. This data reflects actual user experiences, providing highly relevant insights for making improvements that benefit your users directly. Let us look at the tools for measuring LCP in the field.
1. Chrome User Experience Report (CrUX) data represents the web experience of real-world Chrome users and can be accessed via API. Follow the steps to measure LCP using the CrUX report.
1. Go to Google Cloud Platform and enable the CrUX API.
2. Request data for your website using the API.
3. Download and analyze the data to see LCP and other Core Web Vitals metrics.
4. Identify and address any LCP issues based on the insights from the data.
Using this method allows developers and webmasters to gain insight into how users are experiencing the pages. Based on the same you can improve each Core Web Vitals metric and fix any LCP issues identified.
2. Page Speed Insights (PSI) can help you find out which element is the largest on your page. Follow the steps to measure LCP using the PSI report.
1. Visit the PageSpeed Insights website.
2. Enter your website URL and click "Analyze."
3. Review the report, focusing on the "Diagnostics" section to see which element triggers the LCP metric.
4. Follow the specific recommendations provided to improve your LCP score.
3. Search Console (Core Web Vitals report) is based on real-world user data. It displays a chart for both mobile and desktop platforms that indicates how many pages are good, need improvement, and poor in page experience scores. To measure LCP using the Google search console, follow the steps:
1. Open Google Search Console and navigate to the Core Web Vitals report.
2. Review the charts for both mobile and desktop platforms.
3. Click on the URLs listed to see detailed scores and identify which pages need improvement.
4. Use PageSpeed Insights to get specific suggestions for improving the LCP of those pages.
Lab tools simulate user interactions in a controlled environment, allowing you to test and diagnose performance issues before they affect real users. These tools provide detailed insights and controlled conditions to help pinpoint specific problems. Let us look at the tools for measuring LCP in the lab.
1. Chrome DevTools: Just go to the page you want to test an LCP score for. Then right-click to open the “Inspect” panel, find “Performance”, and refresh the page. After reloading, you will see all the metrics in action on the page. The recording will show both the First Contentful Paint and Largest Contentful Paint.
2. Lighthouse analyzes the web performance of a page and generates a report containing metrics and suggestions for improving them.
Follow the steps to measure the LCP using Lighthouse:
1. Open the webpage you want to test in Chrome.
2. Right-click on the page and select “Inspect” to open DevTools.
3. Go to the “Lighthouse” tab in DevTools.
4. Click “Generate report” to start the analysis.
5. Review the Lighthouse report for LCP score and follow the suggestions for improvement.
3. WebPageTest is a free web-based tool that measures LCP. It uses the lab method to simulate different scenarios and record their results. It offers more detailed information about the page like DOMContentLoaded, time spent on each object, and total time spent loading the page. This can help further optimize your site for speed.
1. Go to the WebPageTest website.
2. Enter your website URL and configure the test settings (e.g., browser, location).
3. Click “Start Test” to initiate the performance test.
4. Wait for the test to complete and review the detailed results, focusing on the LCP time and other performance metrics.
5. Use the insights from the results to identify and fix issues that affect your LCP score.
LCP is a Google-created metric, we can readily discover it in all of these tools. It enables the use of a Largest Contentful Paint test as necessary, as well as ongoing monitoring of the results.
As you have seen, your LCP score is critical to the overall performance of your website. With this in mind, let us look at ten practical techniques to boost your website's score and make it load more quicker.
1. Using a CDN
To improve the Largest Contentful Paint (LCP) and potentially the user experience, a content delivery network (CDN) is a great tool to optimize website traffic management.
CDNs can help reduce network load by balancing the user requests over multiple servers rather than queuing them up on the origin server. It can result in a faster LCP score and improved user experience. Additionally, larger sites that receive more traffic may want to consider using a CDN for their website.
Image CDNs can also further improve website speed by optimizing the transformation and size of images in real time. These can be beneficial for websites that are rich in media content. Setting up a CDN depends on your hosting provider and can be done quickly and easily.
2. Image Optimization
Optimizing images is a great way to improve Largest Contentful Paint (LCP) performance. To reduce a website's loading time, you should compress and resize their images, convert images into a new format, use responsive images, exclude the LCP element from lazy-loading, and use a static image instead of a slider.
Google recommends that images be converted to the WebP format for optimal performance. Additionally, responsive images should be used for desktop and mobile, as each device's image size should differ. Lastly, it's best to avoid using a slider because it can be too heavy to load due to code.
By optimizing images, users can address Page Speed Insights audits such as “Serve images in next-gen formats,” “Properly size images,” “Efficiently encode images,” and “Avoid enormous network payloads.” Optimizing images effectively boosts the Largest Contentful Paint performance and, ultimately, the user experience.

3. Improve Server Response Time
Improving server response time is one of the key ways to optimize the Largest Contentful Paint (LCP) score. This can be done by implementing server-side caching, upgrading server specifications, and optimizing application code. For WordPress websites, plugins such as WP-DBManager can help reduce bloats and schedule automatic cleanups. By taking these steps, web owners can ensure faster page loading times and improved user experience.
4. Fix Lazy Loading Issues
Lazy loading effectively reduces page loading time; however, it can sometimes worsen the Largest Contentful Paint (LCP) score. The LCP score measures the time taken for the main content of a page to render. If a website's images follow lazy loading behavior, it can lead to a lower LCP score.
To fix this issue, hero or featured images should be tagged with the attribute loading="eager," which allows the image element to render immediately without waiting for users to scroll down. Additionally, you can disable lazy loading on images rendered above the fold so browsers can load them without executing JavaScript beforehand.
5. Enable Caching
Page loading time is one of the most important aspects of website performance. Long loading time can negatively impact user experience and directly affect search rankings.
Caching is an effective way to reduce page loading time and improve LCP. Caching involves storing static web page components in temporary storage, which saves the server from reconstructing it each time a user visits the page.
There are two main caching methods – server-side caching and browser caching. Server-side caching involves storing a pre-made web page version on the origin server, while browser caching lets visitors keep components in their local storage. By leveraging both caching methods, users can avoid downloading the same data whenever they visit your site.
6. Use a Reliable Web Hosting Provider
The hosting quality can impact the Largest Contentful Paint (LCP) score. Hosting platforms have various features that can improve the user experience and simplify web management. Good hosting is properly configured to ensure your website has the best speed and performance, which can significantly affect the LCP. Therefore, it is essential to select an appropriate hosting plan that meets the needs of your website. Doing so can help minimize the load time and improve the website's overall performance.
7. Eliminate Render-Blocking JavaScript and CSS
Render-blocking resources are typically found in CSS and JavaScript files and can cause elements on a page to load slower, resulting in a poor online experience.
To improve core web vitals and reduce bounce rate, it is essential to eliminate render-blocking CSS and JavaScript. This is known as progressive loading and can be achieved with the help of specific plugins. Lab tools can also suggest which non-critical CSS or JS files should be removed for improved performance.
8. Minify JavaScript, CSS, and HTML Files
Minification is a method of lowering file size that mostly involves eliminating lines of code within the file. It is one of the most frequent file optimization techniques for improving your LCP metric.
Specific fundamental files, such as CSS, JavaScript, and HTML, may have numerous unneeded white spaces inside the code, increasing their size. Even though they may not appear substantial separately, they might harm site performance when combined.
Web admins may manually minify CSS, HTML, and JavaScript files or use plugins.
9. Compress Text Resources
To optimize the transfer process of text resources like CSS, HTML, and JavaScript, minification and compressing can be great options. GZIP compression is a popular choice for text compression, and it falls into the lossless category, meaning the original file and its information will be preserved. You can easily enable GZip compression on your website.
Additionally, some web hosting companies offer GZIP compression as part of their services. Compressing your text resources can reduce their file size and make your website more efficient, resulting in a better LCP score.
10. Defer Parsing of JavaScript
People want web pages to load quickly and efficiently, and Defer Parsing of JavaScript is a method that helps to achieve this. This technique involves delaying the processing of non-essential JavaScript code on a page and enabling the browser to prioritize loading the essential page content first.
Defer Parsing of JS can drastically improve page load speed and, consequently, user experience and help optimize the Largest Contentful Paint (LCP) metric. To defer parsing of JavaScript, you can manually modify the function.php file or use external tools.
The current process of optimizing web pages for LCP only allows you to optimize the scores for one web page at a time. This can be a challenge if you have a website with thousands of web pages. Existing tools do not allow you to optimize and track your LCP across your entire website.
The Quattr platform addresses the shortcomings of the current process and helps you optimize your site to improve overall page experience and LCP Scores. You can use Quattr to view LCP scores for each page of your website all at once and filter pages based on whether the LCP score is Good, Needs Improvement, or Poor. Quattr also lets you compare LCP, and other Core Web Vital scores against your competitors in one view.
With Quattr, you can scale and optimize render-blocking resources for multiple pages. The Usability Recommendations dashboard in Quattr gives you a list of prioritized recommendations and performance improvements you can make across your entire site.
This list is ranked based on what key pages you should focus on and aligns optimization efforts with business metrics like clicks and conversions so that you can measure the benefits of your efforts.
LCP is a great metric to understand how well your page is performing. It can help you understand how fast your website loads and how well it performs on different devices. The above guide helps you understand what affects LCP and how to fix LCP issues.

Largest Contentful Paint (LCP) is a metric used to measure the loading performance of a webpage. It is a timing metric that measures when the main content of a page has finished loading and provides information about how quickly the page's main content is being displayed.
LCP scores are measured using tools such as Chrome's Lighthouse, Pagespeed Insights, and WebPageTest. These tools measure how long the page's main content is to render. They also provide information about the page's loading performance by measuring factors such as the time for the initial server response, time for the first byte, and time for the page to load. The higher the LCP score, the better the page's loading performance.
To improve LCP, webmasters should optimize webpages for speed, reduce page size by compressing and resizing images, minifying and combining files, and caching static content. Additionally, webmasters should keep an eye on render-blocking resources, reduce JavaScript execution and prioritize visible content. Lastly, optimizing server response time is also essential.
To optimize LCP for mobile, webmasters should ensure that the page is optimized for mobile devices, ensure the page is responsive, reduce page size and the number of HTTP requests, and improve the speed of external resources. Additionally, webmasters should prioritize visible content, enable preloading and pre-rendering, reduce render-blocking resources, and minimize the use of JavaScript.
