Why LCP Matters for SEO and How to Optimize It for Better Rankings

Have you gone to a website and found yourself staring at the blank screen for what felt like an eternity? Slow website loading speeds can frustrate users, leading to decreased website traffic and engagement. This is where Largest Contentful Paint (LCP) comes into play.

Google’s recent Core Web Vitals update, which emphasizes user experience, has highlighted the importance of LCP in website optimization. Website owners must focus on LCP optimization to rank better and appear higher on search engine results pages (SERPs).

But what exactly is LCP, and why does it matter for SEO? In this article, we’ll dive into the meaning of LCP, its impact on SEO and user experience, and strategies for optimizing LCP for better website rankings.

LCP stands for Largest Contentful Paint, a Core Web Vital metric measuring website loading speed and user experience. It represents the page load time taken by the largest content element on a particular page to become visible to the user. They could be an image, videos, or block-level elements.

LCP is crucial in determining a website’s loading speed and perceived performance. Websites with a slow LCP score tend to have a higher bounce rate, as users will likely abandon the site if it takes too long to load. Google has made LCP a part of its Core Web Vitals update, meaning it will play a vital role in determining a website’s search engine ranking.

LCP can be measured using various web performance testing tools, including Google’s PageSpeed Insights, WebPageTest, and GTmetrix. These tools provide insights into how long it takes for the largest content element to load and how it affects the user experience.

Why LCP Matters for SEO

Here are several reasons why LCP matters for SEO:

  • User Experience: A fast-loading website provides a better user experience, making users more likely to engage with it. Slow-loading websites lead to higher bounce rates and lower dwell times, negatively impacting SEO.
  • Rankings: Google’s algorithms prioritize websites with better user experiences, and LCP plays a significant role in determining website rankings. Websites with faster LCP scores will likely rank higher in search engine results pages (SERPs).
  • Mobile-First Indexing: With Google’s mobile-first indexing, LCP has become even more critical for SEO. As more users access websites on mobile devices, the loading speed of LCP on mobile devices has become a crucial factor in mobile SEO strategy.
  • Core Web Vitals: As mentioned earlier, LCP is one of the common Core Web Vitals, which Google has made a priority in its ranking algorithms. Websites that meet Google’s Core Web Vitals guidelines are more likely to rank high in SERPs.

What Is a Good LCP Score?

What Is a Good LCP Score?

A good LCP score is essential for a positive user experience and improved website ranking.

In general, a good LCP score should be less than 2.5 seconds. According to Google, an LCP score between 2.5 and 4 seconds needs improvement, while an LCP score above 4 seconds is considered poor and may decrease website ranking.

However, it is important to note that LCP scores can vary based on the type of website and device used to access it. For example, a website with rich media content, such as videos and images, may have a higher LCP score than a website with minimal content.

Additionally, mobile devices may have a slower internet connection and processing speed, leading to a higher LCP score compared to desktop devices.

It’s also worth noting that LCP is just one aspect of website performance. Other factors, such as First Input Delay (FID) and Cumulative Layout Shift (CLS), are also important in providing an excellent user experience and improving website ranking.

When Is the Largest Contentful Paint Reported?

When Is the Largest Contentful Paint Reported?

LCP is reported during the loading phase of a web page. It usually measures the time it takes for the largest content element to load, which is usually an image, video, or block of text. Once the largest content element is loaded, the LCP is reported and displayed in the web page’s performance report.

The LCP measurement is affected by various factors, such as server response time, image and video compression, and browser rendering time. To ensure a good LCP score, website owners and developers must optimize these factors to ensure the largest content element loads quickly.

It is vital to note that the LCP measurement can change depending on the device and network conditions used to access the website. Therefore, testing the website’s LCP on multiple devices and networks is advisable to get a more accurate measurement.

How to Measure LCP

How to Measure LCP

To measure LCP, there are a few tools and techniques that you can use:

  • Google PageSpeed Insights: Google PageSpeed Insights is a popular tool for measuring LCP. It analyzes the website’s performance, including LCP, and makes recommendations to optimize it.
  • Lighthouse: Lighthouse is an open-source tool that measures a website’s performance. It provides a detailed Core Web Vitals report that includes LCP and other Core Web Vitals.
  • WebPageTest: WebPageTest is a tool that comprehensively analyzes website performance. It measures LCP and other Core Web Vitals metrics, like Time to First Byte (TTFB) and First Contentful Paint (FCP).
  • Chrome DevTools: Chrome DevTools is a built-in tool in Google Chrome that allows developers to analyze a website’s performance. It provides detailed information on LCP, including the element that caused it and the time taken to render.

When measuring LCP, it is essential to understand the interpretation of the results. An LCP score that is less than 2.5 seconds is considered good, while a score of more than 4 seconds is poor.

It is also vital to note that several factors can affect LCP measurements, such as network speed, server response time, and caching. Therefore, measuring LCP multiple times and under different conditions is recommended to obtain an accurate measurement.

What Elements Does the Largest Contentful Paint Measure?

What Elements Does the Largest Contentful Paint Measure?

The largest contentful paint measures the following elements:

  • Images: The largest image on the screen is typically the largest contentful paint element. This could be a hero image or a product image that dominates the screen.
  • Videos: LCP also measures the largest video element on the screen, such as a video player or a background video.
  • Text blocks: Sometimes, the largest content element on the screen is a block of text, such as a heading or a paragraph.
  • Other content: LCP can also measure other content elements that are visually prominent, such as a large button, banner, or graphic.

It is important to note that LCP only measures the total loading time of the largest content element that is visible above the fold. This means that any content below the fold, such as content that requires scrolling to view, is not included in the LCP measurement.

How to Optimize LCP for Better Rankings?

How to Optimize LCP for Better Rankings?

LCP measures the time taken for the largest element on the website to load, typically an image or video. A slow LCP can lead to higher bounce rates, lower engagement, and ultimately lower rankings on search engines like Google. Here are some ways to optimize LCP for better rankings:

1. Minimize Server Response Time

The time it takes a normal website to load depends on the server’s response time. The website can load faster by reducing server response time, and the LCP can improve. This can be done using a reliable web hosting service, optimizing website code, and reducing the number of HTTP requests.

2. Optimize Images

Images are often the largest element on a website, which can slow down the LCP. To optimize images, they can be compressed without sacrificing quality, and lazy loading can be implemented to delay the background image loaded until they are needed.

3. Use a Content Delivery Network (CDN)

A CDN distributes website content across multiple servers, reducing the required time it takes to load the website. This can improve the LCP by reducing the distance data travels from the server to the user’s device.

4. Minimize JavaScript and CSS

Large JavaScript and CSS files can slow the LCP as render-blocking resources. Minimizing the render-blocking JavaScript and CSS files allows the website to load faster and improve the LCP. This can easily be done by removing unnecessary code, minifying the files, and using asynchronous loading.

5. Prioritize Above-the-Fold Content

Above-the-fold content is the content that is visible to the user before scrolling down. By prioritizing this content, the website can load faster and improve the LCP. This can be done by placing important content above-the-fold, and deferring non-critical resources.

6. Prioritize Content Loading

Loading critical content first is essential for improving LCP. You can achieve this by using lazy loading techniques to defer the loading of non-critical images and videos until after the initial rendering of the webpage.

7. Use a Fast and Reliable Hosting Provider

Using a fast and reliable hosting provider helps improve LCP by providing a stable and secure server environment. You should choose a hosting provider with fast loading times, high uptime, and excellent customer support.


LCP plays a crucial role in the SEO of a website. Google’s Core Web Vitals update has clarified that having a fast-loading website is now an essential ranking factor. Optimizing LCP is, therefore, a vital step to improve the website’s visibility in search engines and attract more traffic.

Using the best SEO tools and implementing best practices can significantly improve your website’s LCP and enhance the user experience. In the end, optimizing LCP is not just about improving your website’s ranking.

Still, it’s also about providing visitors with a better experience and keeping them engaged with your content. By prioritizing LCP optimization, you can take your website’s SEO game to the next level and achieve your online goals
