User experience is the most important factor that will lead to the success or failure of your website. One of the most significant factors affecting user experience is the largest contentful paint (LCP).
LCP or Largest Contentful Paint is a metric that tracks the loading of the largest content element on a page. In other words, it measures how quickly a webpage renders its most meaningful content. In this article, you will go deeper into what LCP is and how can you improve it on your website. So, read on to learn more!
What Is Largest Contentful Paint?
Largest contentful paint (LCP) is an important metric for web performance as it measures the speed at which the main element of the content on the page loads, such as large blocks of text or images. It is a significant metric of user experience and holds tremendous importance in SEO.
The type of content plays a crucial factor in this too. This metric only tracks the loading time of user-experience-critical elements, including:
- Images.
- Image tags.
- Video thumbnails.
- Background images with CSS.
- Text components, including paragraphs, headers, and bullet points.
How to Improve the Largest Contentful Paint (LCP)?
By improving your website's LCP, you can significantly improve your website's overall performance. There are a few ways to enhance LCP, such as hosting your web content on a content delivery network. For the best performance results, consider trying the following tips:
1. Utilize a CDN
A content delivery network (CDN) is a network of servers that provides users with your website’s content in the quickest way possible by distributing content around the world. When your website is on a server that is closer to the users, it can shorten the distance data needs to travel significantly, which can lead to faster page loading and improved LCP.
2. Optimize JS, CSS, and HTML Files
Next, minifying JavaScript, CSS, and HTML files is another great way to boost LCP. These files may contain unnecessary characters or code that expands their size, and the larger the file, the slower the website. When these files are minified, they are compressed to reduce their size, resulting in faster loading times. This is one of the most common ways to improve the largest contentful paint metric.
While you can minify JS, CSS, and HTML files manually, there are also plugins available for content management systems (CMS) like WordPress. Fast Velocity Minify and WordPress Super Minify are some of the popular plugins for this.
3. Compress and Resize Images
To enhance your LCP metric, it's essential to optimize your images by compressing and resizing them. Here are some effective techniques commonly used for image optimization:
- Compress images before uploading.
- Use formats optimized for faster loading.
- Replace GIFs with videos for better performance.
- Ensure image size and dimensions align with the page layout.
4. Enhance Server Response Time
Your website’s performance is directly proportional to the server response time. If your site is taking a long time to load, your server response time likely is one of the main factors slowing down the process. To improve your server response time, here are some effective techniques you can try:
- Implement server-side caching: Caching is a process where you store a copy of a file on the server for a limited time so that the user doesn’t have to download it again from the server. The server-side caching feature is usually available on your hosting configuration.
- Upgrading server specifications: Consider upgrading your server with better CPU capabilities and larger storage, as a server hardware specification is a crucial factor that directly impacts your site performance.
- Optimize application code: Optimizing your web application code is one of the best ways to improve your server response time. For example, removing unnecessary CSS can help you enhance the initial rendering time.
5. Choose a Trusted Web Hosting Provider
Web hosting is one of the backbones of your website. With that being said, a poor hosting provider can have a negative impact on your site's performance. Good hosting typically offers a variety of features that can help improve the user experience and increase the performance of your site. Therefore, it is essential to choose a reliable and high-quality web hosting provider that fits your site specifications and improves the overall site performance.
6. Select Appropriate Fonts
Next, you need to also pay attention to the fonts used on your website to optimize the largest contentful paint. Website font files are generally larger, which can increase loading times. To address this matter, you can try reducing font file sizes and updating page styles to improve loading speed. This approach has proven to be effective in enhancing overall website performance.
7. Resolve Lazy Loading Problems
Lazy loading speeds up page loads by delaying the loading of non-essential content like images and CSS until they're needed. This can improve LCP, but sometimes it can actually worsen it.
For example, if all images are lazy loaded, the hero image might not load quickly enough to be the LCP element. To fix this, you can mark the hero image with loading="eager" so it loads immediately.
Lazy loading with JavaScript can also slow things down because the browser has to run the JavaScript before loading the image. To avoid this, disable lazy loading for images above the fold. This way, the browser can load them directly without the JavaScript delay.
8. Remove Render-Blocking JavaScript and CSS
Render-blocking JavaScript, scripts that prevent the browser from displaying content until they’re fully loaded and executed, can slow down page loads because they’re not ready for use until the rest of the page has finished loading.
It’s usually found in CSS and JS files, which might cause a delay in rendering the page, resulting in the page taking longer to load. Unfortunately, this will give the impression that your website is slow and unresponsive, thus decreasing the user experience.
Therefore, eliminating render-blocking JavaScript and CSS should be your first priority to get a better core web vitals score. This enables the use of progressive loading, which can contribute to lowering the bounce rate.
9. Compress Text Resources
In addition to minification, compressing is another effective way to optimize text resources, such as CSS, HTML, and JavaScript. By reducing file sizes, you can speed up data transfer and correspondingly improve LCP performance.
A widely used compression technique is GZIP, which falls under the category of lossless compression. This ensures that all file information is preserved during the compression process. Or, you can also activate GZIP compression through WordPress plugins like WP Rocket or by utilizing free online tools.
10. Defer JavaScript Parsing
Web browsers usually load code sequentially from top to bottom, giving priority to JavaScript files before moving forward. This can slow down page loading times and negatively impact user experience.
Deferring the parsing of JavaScript involves postponing the processing of non essential JavaScript code on a webpage. This approach allows the browser to focus on loading critical page content more quickly, helping to retain visitors’ attention.
That wraps up the discussion about Largest Contentful Paint and how to improve it. Improving your website's LCP is a crucial step in enhancing user experience and search engine rankings.
