How To Improve First Contentful Paint || Doing this with an Image CDN.

When you are loading a webpage, and all you can see is a blank white screen, well, that is normal. You just have to wait for something to come up, maybe some text, images, or even a button on the page.

That will give you the sense that the page is loading, and then you wait for the whole page to load completely.

But what if nothing comes up on that blank screen for about 3 seconds? My best guess is that you exit the page and move to a new one to get what you seek.

That is what your users do each time they try loading your website, and it takes too long before anything is displayed.

If something (the first piece of content) shows up in less than 1.8 seconds, then a user would wait for the page to load, but if it takes more than that, your chances of increasing bounce rate are high.

This is why you must ensure that your website’s first piece of content is displayed on a user’s screen as quickly as possible.

There are many ways to make this happen, but the major way of getting this done is using an Image CDN to improve your score on the web vital metric that measures this aspect of your website; The First Contentful Paint Metric.

What is First Contentful Paint (FCP)?

First Contentful Paint is a web vital metric that measures how long your users will have to wait before they can view the first piece of content on your website. FCP basically lets you know how much time a user spends staring at a blank screen after clicking on a link to your website.

This is a vital web metric because of its impact on the user experience. Just like I said earlier, when a user can see the first piece of content on a page, it gives them a sense that the page is loading, and all they can do is wait a little while for it to load completely, but if they don’t see that first piece on time they will leave.

So to keep a user anticipating your complete content, you should serve them the first one fast, meaning you need to improve your First Contentful Paint (FCP) Score. But before we go into improving the FCP score, you need to know what a good FCP score is to evaluate your efforts in improving this metric.

What is a good FCP score?

The image above gives you the answer to this question. A good First Contentful Paint score is one between 0 – 1.8 seconds. This is how long an average internet user can spend staring at a blank screen; anything more than that will frustrate them, and they leave.

FCP ScoreCategory
0 – 1.8 sec.Good
1.8 – 3.0 sec.Need Improvement
Above 3.0 sec.Bad

Scores above 1.8 seconds need to be improved, and the best part is this: as you improve your FCP score, other website website speed metrics are also improved.

How to Check your FCP Score.

To check your FCP score, all you have to do is to enter your URL into VitalFrog and get your website analyzed. VitalFrog then shows you a report containing your website FCP score and other web vital metrics like the core web vitals.

How To Improve FCP With Image CDN.

When working to improve the First Contentful Paint score, the goal is to cut down the amount of time a user spends staring at a blank screen. This is the major goal, and it can be achieved with an Image CDN.

What Are Image CDNs?

Image Content Delivery Networks (CDNs) are distributed networks of servers and data centers that focus on images.

Unlike a regular Content Delivery Network (CDN), which stores the entire content in a website, Image CDN focuses on storing the images, optimizing them, and serving them responsively based on a user’s device and network condition.

How Does An Image CDN Improve My FCP Score?

Before I recommend any Image CDN you can use to achieve this goal, I believe it is essential you understand how an Image CDN improves the FCP score of a website so you can identify which Image CDN is a good fit for this.

1. It improves the server response time for images:

First, just like a regular CDN works, an image CDN stores a copy of your images in its data center across the world. Each time a user loads your webpage, instead of their browser sending a request for your image to your server, it sends it to the closest data center.

If the data center has the cached version of the image, then it will serve it to the user immediately, but if the data center doesn’t have the image stored, it will retrieve it with the image’s URL from the Image CDN storage and then serve it to your users.

The data center also stores the cached version of the image so that the subsequent request for the image doesn’t take so long before a response is sent.

This is an important feature in all forms of CDNs, and it is essential to use one when you are getting a larger amount of traffic from locations far away from your host server as it will improve your server response time and your overall website’s speed.

With an Image CDN, your images will be served to your users fast, and your website’s first piece of content will be visible to your users as soon as possible.

Note: This will only improve your FCP score if you have an image above the fold because the FCP metric measure only the first piece of content to be displayed above the fold.

2. It improves the load time of the Image:

Responsive Image.

Even after improving the server response time for all your images, Image CDNs can also improve the load time of the images, so they are quickly visible. It does this by optimizing the images in real-time using URLs.

When you store your image in an Image CDN, a URL is automatically assigned to it. This URL helps the CDN retrieve an image from its location when a request for it is made.

For example, an image with the file name frog.jpg could be assigned a URL like, which is used to locate the image in the CDN’s storage.

This URL can also perform a real-time transformation on the image to make it responsive to a user browser type, viewpoint size, network condition, and so on. All of these can improve the load time of the images.

For example, depending on the user’s browser support, you can set your CDN to server your images in AVIF, WebP, or JPEG format. You can also set an auto-resize which ensures that your images are well displayed on desktops and mobiles, reducing the image’s file size.

With this said, it is clear that using an Image CDN will improve your website’s image content load time and make them highly responsive.

Note: It is essential to know that using an Image CDN will not only improve your website’s First Contentful Paint score, but it will also improve other web vital metrics like your Largest Contentful Paint (LCP) if the largest element above the fold is an image.

Now you know how an Image CDN works to improve your website’s First Contentful Paint, let me show you some of the best Image CDN available.
