Resolve LCP issue with CDN: My Experience of Website Performance Improvement

LCP (Largest Contentful Paint) is a key metric for web performance, measuring how long it takes for a user to see the main content of a webpage after opening it.

This indicator is crucial for assessing user experience because it directly affects the user’s perception of the page loading speed.

In today’s competitive internet environment, where user expectations for page load times are constantly rising, optimizing LCP has become one of the important tasks in website performance optimization.

The value of LCP depends on various factors, including but not limited to server response time, network conditions, browser parsing speed, and the structure and resource loading sequence of the webpage itself.

How to improve LCP

To improve LCP, site owners need to address these areas and take appropriate optimization measures. For instance, using a CDN (Content Delivery Network) can shorten server response times, or optimizing the loading strategy of images and videos, such as using lazy loading technology, only loading content when the user scrolls to a certain part of the page.

Furthermore, reducing the execution of JavaScript code that blocks rendering is another important approach to optimizing LCP. Executing JavaScript can block the browser’s rendering process, leading to delayed loading of page content. By optimizing the execution order of JavaScript code and reducing unnecessary calculations, the rendering speed of the page can be accelerated. Additionally, using modern front-end technologies like WebP image format and HTTP/2 protocol can also improve the efficiency of content transmission, thereby enhancing LCP.

In practice, we can use tools like Google’s PageSpeed Insights to detect and analyze the LCP performance of web pages. These tools provide detailed performance reports, identify specific factors affecting LCP, and offer corresponding optimization suggestions. Following the guidance of these tools, developers can optimize targeted areas and gradually improve the performance of the webpage.

In summary, LCP is an important metric for measuring web performance, and optimizing it can enhance user experience, reduce bounce rates, and increase user retention. Developers should pay attention to LCP optimization, comprehensively applying various optimization techniques to continuously improve the performance of webpages and meet the growing demands of users.

My experience: Resolve LCP Issues with Cloudways CDN

Recently our team was tasked with maintaining and optimizing a large e-commerce website. As the user base grew, we noticed that the website’s loading speed had become a serious issue, particularly on mobile devices. User feedback indicated that long page load times were negatively impacting their shopping experience and conversion rates.

To address this issue, we first used Google’s PageSpeed Insights tool to identify bottlenecks. The report revealed that the LCP (Largest Contentful Paint) value was far beyond the recommended threshold, meaning users were not able to see the main content of the page for a long time.

After analysis, we identified several key factors: firstly, the homepage contained a large number of high-resolution images and complex JavaScript scripts; secondly, due to the server being located far from the users, network delays resulted in longer content loading times.

To solve these issues, we decided to introduce Cloudways’ Content Delivery Network (CDN) service. Cloudways’ CDN is a globally distributed network that caches static resources of the website on edge servers around the world, allowing users to access data from the nearest server, greatly reducing the distance and time required for data transmission.

After implementing Cloudways CDN, it optimized the website’s resources by compressing image files, reducing unnecessary HTTP requests, and minifying JavaScript and CSS files to reduce loading times.

After configuring the CDN, we ran PageSpeed Insights again for testing. The results showed significant improvements in the LCP value, with the page loading speed increasing significantly. User feedback also confirmed this, with them reporting faster response times and improved shopping experiences.

This experience taught us that using a CDN is an effective way to resolve LCP issues and improve website performance. Cloudways’ CDN service provided us with a simple and easy-to-use solution, helping us quickly fix performance bottlenecks and enhance user satisfaction. Through this practical application, we learned how to use modern technological tools to meet challenges and continuously optimize the user experience.
