First Contentful Paint (FCP) vs Largest Contentful Paint (LCP) – Why You Can’t Ignore them in 2021
Google recently announced that they are going to evaluate the website speed ranking using FCP. But, why are these metrics considered better than the conventional speed tests?
Well, FCP will give you a solid idea about the performance of your site. If you want to improve its performance to provide users with a positive user experience, these metrics are crucial. And, ultimately, they will spend more time browsing your website.
On the other hand, the Largest Contentful Paint provides information on how much the main content of a page takes time to download. And, get available to interact with the user.
What is First Contentful Paint?
Let’s first check out the First Contentful Paint meaning. It is a user-friendly metric that helps to measure the page load speed. The browser will need to render some content for FCP.
First Contentful Paint (FCP) is when the browser renders the first bit of content from the DOM (Document Object Model), providing the first feedback to the user that the page is actually loading. The question “Is it happening?” is “yes” when the first contentful paint completes.
But how is it different from the traditional tools? It measures how long it takes the browser to show the first bit of Document Object Model (DOM) content, such as images, text, SVGs, and non-white elements after the user navigate your website.
Ways To Measure First Contentful Paint
You can measure it through both lab tests and field tools. Various tools are there to help with measuring the First Contentful Paint. Some of these tools are:
- WebPage Tests
- PageSpeed Insight
- Search console
- Chrome user experience report
- Chrome DevTools.
What Causes A Poor First Contentful Paint Score?
There are a variety of reasons which can affect the FCP score. If you know how they affect your score, you can avoid them to tweak the overall performance. Some of these reasons are listed below.
Render Blocking Scripts And External Stylesheet
Render Blocking is when something causes an issue in the Document Object Model (DOM) rendering. The browser has to process these certain code-obstacles before carrying out any further operations. Even though many of these are crucial, you can delay them to improve the score.
Large Text-Based Assets Can Cause Low Score
Another way is to remove irrelevant characters, along with spaces. It will create a compact file, which takes up a lot less space than the original file.
Why should You Consider First Contentful Paint as an SEO Matter?
For any website, a solid SEO strategy is a must. Without it, the website ranking will suffer. Google uses First Contentful Paint as a metric to assess the performance of a site.
So, how does it affect SEO?
For the search engine bots, SEO is one of the aspects when it comes to website ranking. When it comes to the best SEO practices, you cannot avoid the page loading speed. The FCP score will help you to improve the loading speed and take your website one step ahead towards a higher search engine rank.
How To Improve First Contentful Paint?
For one reason or another, your website may get a low FCP score. You can improve it in various ways to get a high score and performance. These are as follows:
Use Caching For Your Site
One way to reduce TTFB (Time TO First Byte) is through caching. How? Well, caching helps to decrease the server processing time and assist you to improve your website loading speed.
Get Rid of Unused CSS
Unused CSS can consume a lot of bytes. Plus, it slows down the render tree construction of your browser. The browser will need to confirm applicable CSS rules for the nodes when constructing the tree. The more the unused CSS, the more time the browser will take. You can use Chrome DevTool’s coverage tab to find them.
Stay Away From Large Network Payloads
To speed up your site and increase the FCP score, avoid large payloads, i.e. large file size at any cost. Not only will it make the site lose a high search engine rank, but it will also cost a lot of money.
Plus, the higher the payload, the larger the page, which results in increased page loading speed and downloading time. When you reduce the overall size of the network requests, it will improve the user experience.
Steer Clear From Lazy Loading Above The Fold Images
Optimize The Document Object Model (DOM) size of Your Site
A large-sized Document Object Model (DOM) can negatively affect your First Contentful Paint score. During the primary stages of loading, an unoptimized tree will include nodes that are invisible to the users.
Also, a large Document Object Model size requires more time to process to style, and compute the nodes, which can negatively affect the rendering. Additionally, it can also overwhelm the memory of any device.
Case Studies of First Contentful Paint
Any website should achieve a fast loading time and a decreased bounce rate through proper optimization.
Sooner or later, your unoptimized site will fall behind the competition. Most users leave a site if it takes too long to load. Therefore, website optimization should be the main priority for any website owner.
The case studies show the before and after results for a website, after optimization. These studies show that a variety of tools were used such as page speed insights and heat maps.
These tools will provide one with essential information needed for the evaluation, for example, First Input Delay (FID), First Contentful Paint (FCP), lead magnet clicks, and the rate of engagements.
To understand the impact of the optimization, one needs to check the pre-optimized data of the website. The score will let you know where the website needs improvement.
After carrying out the optimization, one can find the average page loading speed.
However, a higher speed can be a bonus for the ranking. But, in reality, this is nothing more than a few digits without much value in it. Yet, it does help the website to get a rank in the search engine.
The Lab Data will show the following metrics:
- First Contentful Paint
- Speed Index
- Largest Contentful Paint
- Time To Interactive
- Total Blocking Time
- Cumulative Layout Shift
Lab data may not be enough to get a better understanding of the score.
It is ideal if you use both lab and field data.
Various case studies tried to understand how a good First Contentful Paint score will benefit a website. Most of the results showed that an optimized site with excellent performance showed an increased First Contentful Paint score.
But, what is a good First Contentful Paint score? The First Contentful Paint should happen within 1 second and not more than this.
What Is the Largest Contentful Paint?
Largest Contentful Paint is another crucial metric, and it helps to measure when the largest element becomes visible and ready for user interaction.
Google Web Vital also includes the Largest Contentful Paint metric to measure the website loading speed.
LCP will count the loading time for relevant elements to provide a user with a better user experience such as image tags, image, background images with CSS, and text elements.
In short, it is one of the hassle-free metrics to understand. One only needs to take any largest element (text, image, or LCP animation) from the website and optimize its loading time.

What Causes A Poor Largest Contentful Paint Score?
Various reasons can affect your Largest Contentful Paint score. These can vary from one site to another. If you know these, you can optimize your site to elevate the score. Some common reasons are as follows:
Client-Side Rendering Can Hurt Your Score
However, there are various optimizations that one can consider, for example, pre-rendering and server-side rendering.
Slow Resource Loading Time Can Affect LCP Score
- <video> elements
- <img> elements
- Block-level elements
Slow Server Response Time
The browser will first need to receive the content before it can display anything on the screen. If the server delays in sending the content, it will end up on a slow loading page. A fast server will ensure an increased page loading speed. Consequently, it will also improve the Largest Contentful Paint score.
To measure the server time response, you can use the Time To First Byte (TTFB).
Why Should You Consider Largest Contentful Paint AS A SEO Matter?
For Google, the Largest Contentful Paint plays a vital role when it comes to SEO ranking. It accounts for twenty-five percent of the Lighthouse 6.0 performance score. And this particular representation has made it an important metric to be considered.
An enhanced user experience will result in a higher ranking. If there is a tough competition of websites trying to secure a spot in the top ten of the first page of search engines, then the Largest Contentful Paint is crucial to give the site a head start.
How To Improve Largest Contentful Paint?
Since this metric is important, you need to make sure that your Largest Contentful Paint score remains high to give your website an advantage over its competitors.
Similar to First Contentful Paint, you can also tweak your Largest Contentful Paint score by following some methods. Some of these largest content paint improve methods are as follows:
Optimize The Server To Improve The LCP Score
The loading time of your website depends a lot on the server. And this is why you need to find a well-reputed server that offers a better infrastructure to help the site improve its performance. If the server is not fast enough, your site users will see an empty page, until the server fully responds.
Optimize The Images of Your Website
Using incorrect image size will hurt your Largest Contentful Paint score. If the browser takes a long time to load the image, it will slow down the website loading speed. Always check if there are any specific sizing recommended by your hosting service.
Store The Website Page Assets Using Cache
By caching the HTML pages in the server-side caching system, you can effectively decrease the overall response time. You can use reverse proxies to act like cache servers. You can use cloud systems (Azure and Firebase) as they have their cache systems.
Make Use of Browser Hints
There are wide ranges of browser hints you can use such as defer, pre-render, preload, and prefetch to improve your Largest Contentful Paint score. Specific browser hints are applicable for certain actions. For example, use the defer browser hint for unrelated files to the Largest Contentful Painting content.
Try Using Content Delivery Network To Improve The Score
A CDN service helps to make your browser fast enough for users located outside your geographical area. The farther the users are away from your location, the more time it will take as the browser request will need to move to load the site. To make your image load fast, you can also use a Content Delivery Network service.

How Do Images Impact Largest Contentful Paint?
One of the most common pieces of content across the web is an image. And for good reasons! They are interactive and can attract attention effortlessly. Any website comes with a range of images in the form of a banner, advertisement, product images, etc.
We need to make sure that we use images that will not affect the Largest Contentful Paint. As we have seen earlier, using the wrong size will increase the website loading time, ultimately messing up the score.
Also, make sure to decode the images asynchronously, a not-so-common way for optimization. Go for modern image formats. Even though reducing the image size affects the quality, this method will keep the original image quality while decreasing the size. In return, it will improve the Largest Contentful Paint score. Additionally, you can check out the Largest Contentful Paint StackOverflow for more tips.
