How To Improve Your Cumulative Layout Shift on WordPress In 2024

April 9, 2023 | By David Selden-Treiman | Filed in: Core Web Vitals.


To optimize your Cumulative Layout Shift (CLS) on WordPress, focus on implementing responsive design, minimizing render-blocking resources, and regularly auditing your site’s performance using available tools. Additionally, consider server optimization, critical rendering path optimization, and exploring other Web Vitals metrics to enhance the overall user experience.


What Is Cumulative Layout Shift (CLS)?

Cumulative Layout Shift (CLS) is a metric that measures the unexpected movement of elements on your webpage while it’s loading. Imagine you’re browsing a site on your mobile device and, just as you’re about to click a button or read a piece of content, it suddenly shifts down or to the side. That’s a layout shift, and it can be frustrating for users. CLS quantifies this instability, with lower scores indicating a more stable and user-friendly experience.

Why Is a Good Cumulative Layout Shift Important?

A good CLS score is essential for several reasons. First, it enhances user experience by ensuring that your website’s content remains stable and predictable, making it easier for users to engage with your site. A poor CLS score can lead to frustrated users abandoning your website, which can hurt your conversion rates.

Second, search engines like Google consider CLS when ranking websites, so a better score can improve your site’s search engine optimization (SEO). As a rule of thumb, a CLS score of 0.1 or less is considered excellent, while anything above 0.25 needs improvement.

How Do I Optimize My Cumulative Layout Shift On WordPress?

WordPress sites can suffer from poor CLS scores due to various factors, such as slow-loading images, unoptimized web fonts, inconsistent ad placement, and inefficient use of CSS and JavaScript. For example, if you’ve added a large, high-resolution image to your site without optimizing it, it may take longer to load, causing the surrounding content to shift as the image finally appears.

Why Cumulative Layout Shift Is Important for SEO

Optimizing your WordPress site’s CLS score is crucial for creating a seamless and enjoyable user experience, which can ultimately increase user engagement, conversions, and your site’s visibility in search engine results. By following best practices for CLS optimization, you’ll make your website more accessible and user-friendly, while also boosting its SEO performance.

How To Find Your Cumulative Layout Shift Score

Tools for Measuring Your Cumulative Layout Shift

Google PageSpeed Insights

Google PageSpeed Insights is a fantastic tool for analyzing your website’s CLS score and overall performance. Simply enter your site’s URL, and the tool will provide you with a comprehensive report, including your CLS score and suggestions for improvement. It’s a great starting point to identify areas where your WordPress site may be underperforming.


Lighthouse is another excellent tool for measuring your site’s CLS score. It’s an open-source tool developed by Google and integrated into Chrome DevTools, but you can also use it as a standalone application or a Node module. Lighthouse provides a detailed performance audit, including your CLS score and other important metrics, along with actionable recommendations to improve your website’s performance.

Chrome DevTools

Chrome DevTools is a suite of web development and debugging tools built into the Google Chrome browser. You can use DevTools to measure your site’s CLS score and gather valuable insights into your site’s performance. To access DevTools, simply open your site in Chrome, right-click anywhere on the page, and select “Inspect.” Then, navigate to the “Performance” tab and click “Start profiling and reload the page.” Once the recording is complete, you’ll see your CLS score and other performance metrics.

Identifying Cumulative Layout Shift issues

Analyzing the report

After using one of the tools mentioned above to measure your CLS score, you’ll receive a report highlighting specific issues that are causing layout shifts on your site. These issues may include images without dimensions, unoptimized web fonts, or dynamic content like ads and embedded videos. Carefully review the report to identify the problem areas that need attention.

Finding the elements causing layout shifts

To pinpoint the exact elements causing layout shifts, you can use Chrome DevTools. Open DevTools and navigate to the “Experience” tab under the “Performance” panel. Here, you’ll find a list of layout shifts that occurred during the recording. Click on a layout shift event to see which elements on your webpage contributed to the shift. This information will help you address the issues and improve your site’s CLS score.

By measuring your CLS score and identifying the specific elements causing layout shifts, you can start optimizing your WordPress site for a better user experience and improved SEO performance.

Optimizing Images and Media

Properly Sizing Images

Image optimization tools

Optimizing your images is essential for improving your site’s CLS score, as large, unoptimized images can cause significant layout shifts. Tools like ShortPixel and Smush can help you compress and resize your images without compromising their quality.

For example, if you have a high-resolution image that’s 2000px wide but only displayed at 800px on your site, these tools can automatically resize it to reduce its file size and improve loading times.

Responsive Image Techniques

Implementing responsive images is another great way to minimize layout shifts. WordPress has built-in support for responsive images, which means it automatically serves the most appropriate image size based on the user’s device and screen size.

To make the most of this feature, ensure that you’re uploading images with multiple sizes (e.g., thumbnail, medium, large) and using the “srcset” attribute in your image tags. WordPress should handle this automatically, but if you’re looking to highly optimize your images, or if you’re working on developing a theme, doing this manually can be beneficial.

Implementing lazy loading

Native Lazy Loading

Lazy loading is a technique that defers the loading of images and other media until they’re about to enter the user’s viewport. This can significantly improve your site’s CLS score by reducing layout shifts caused by slow-loading media. One way to implement lazy loading is by using the native “loading” attribute, which is supported by modern browsers. Simply add the “loading=lazy” attribute to your image and iframe tags to enable lazy loading.

Lazy Loading Plugins

If you prefer a more automated approach, you can use a WordPress plugin like a3 Lazy Load or Smush to implement lazy loading on your site. These plugins work out of the box, meaning you don’t need to manually add any attributes to your image tags. Just install the plugin, configure the settings, and your site’s images and media will be lazy-loaded automatically.

Using proper aspect ratios for media

Importance of Aspect Ratio Consistency

Ensuring consistent aspect ratios for your images and videos is crucial for preventing layout shifts. When media elements have varying aspect ratios, they can cause the surrounding content to shift as they load. Maintaining consistent aspect ratios helps to avoid this issue and improves your site’s CLS score.

Calculating and Specifying Aspect Ratios for Images and Videos

To maintain consistent aspect ratios, first calculate the ratio by dividing the media’s height by its width. For example, if an image has a width of 800px and a height of 600px, its aspect ratio is 3:4. Once you have the aspect ratio, use CSS to specify the dimensions of the media element’s container. This ensures that the space is reserved for the media before it loads, preventing layout shifts. For example, you can use the “padding-top” property with a percentage value to set the aspect ratio of a container:

.image-container {
    position: relative;
    width: 100%;
    padding-top: 75%; /* 3:4 aspect ratio */

By optimizing your images, implementing lazy loading, and maintaining consistent aspect ratios for your media, you can significantly improve your WordPress site’s CLS score and enhance the overall user experience.

Managing Fonts and Styling

Optimize Web Font Loading

Using Preconnect and Preload

Web fonts can cause layout shifts if they’re not optimized correctly, as they can block rendering until they’re fully loaded. To improve font loading performance, you can use the “preconnect” and “preload” techniques. “Preconnect” establishes an early connection to the font provider, while “preload” fetches the font files ahead of time. For example, if you’re using Google Fonts, you can add the following code to your site’s <head> section:

<link rel="preconnect" href="" crossorigin>
<link rel="preload" as="style" href="">

Choosing Efficient Font Formats

Another way to optimize web font loading is by selecting efficient font formats. Web Open Font Format 2 (WOFF2) is a modern, compressed font format that provides faster loading times compared to older formats like TTF or OTF. When using web fonts, ensure you’re using WOFF2 files for the best performance.

Eliminating Flash of Unstyled Text (FOUT) and Flash of Invisible Text (FOIT)

Using font-display CSS Property

FOUT and FOIT occur when a browser displays a fallback font or hides the text entirely while waiting for the web font to load, which can cause layout shifts. To prevent this, you can use the “font-display” CSS property. The “font-display: swap;” value tells the browser to use the fallback font immediately and swap it with the web font once it’s loaded. Add this property to your `@font-face` declaration in your CSS:

@font-face {
    font-family: 'Roboto';
    src: url('path/to/Roboto.woff2') format('woff2');
    font-display: swap;

Self-Hosting Fonts or Using a Fast Font Provider

Self-hosting fonts can help minimize layout shifts by reducing the number of external resources your site needs to fetch. Download the font files (preferably in WOFF2 format), upload them to your server, and reference them in your CSS using the `@font-face` declaration.

Alternatively, use a fast font provider like Google Fonts to ensure quick font delivery.

By optimizing web font loading and eliminating FOUT and FOIT, you can prevent layout shifts caused by fonts and further improve your site’s CLS score. This not only enhances user experience but also makes your site visually consistent and professional.

Handling Ads and Dynamic Content

Reserving Space for Ads and Iframes

Importance of Reserved Space

Ads and dynamic content like embedded videos or social media widgets can cause layout shifts if they don’t have a reserved space on your webpage. Without reserved space, these elements can push down or reposition surrounding content as they load, negatively impacting your site’s CLS score. Reserving space for ads and iframes ensures a more stable layout and a better user experience.

Techniques for Reserving Space

To reserve space for ads and iframes, you can use CSS to create a container with a fixed size or aspect ratio. For example, if you have an ad that’s 300px wide and 250px tall, you can create a container with those dimensions:

.ad-container {
    width: 300px;
    height: 250px;

For dynamic content with varying dimensions, like responsive ads or embedded videos, you can use the aspect ratio technique mentioned in Section 3:

.video-container {
    position: relative;
    width: 100%;
    padding-top: 56.25%; /* 16:9 aspect ratio */

Avoiding ad reflow

What Is Ad Reflow?

Ad reflow occurs when an ad loads and resizes itself after the page has rendered, causing layout shifts. This is a common issue with dynamically sized ads, and it can significantly affect your site’s CLS score.

Preventing Ad Reflow

To prevent ad reflow, you can use a combination of techniques. First, reserve space for ads as described above. Second, avoid using dynamically sized ads that change dimensions after the page has loaded.

Instead, choose fixed-size ads or responsive ads that adapt their dimensions to the reserved space. Finally, consider implementing ad refresh techniques that don’t cause layout shifts, such as using an ad refresh API or reloading ads within their reserved space.

By reserving space for ads and iframes and preventing ad reflow, you can reduce layout shifts caused by dynamic content and improve your WordPress site’s CLS score. This ensures a more stable browsing experience for your users and can lead to increased engagement and conversions.

Minimizing CSS and JavaScript Impact on Layout Shifts

Inline Critical CSS

What Is Critical CSS?

Critical CSS refers to the minimum set of CSS rules required to render the above-the-fold content of your webpage. Inlining critical CSS means embedding these rules directly in your site’s HTML, so they’re loaded as quickly as possible. This helps prevent layout shifts caused by slow-loading external stylesheets.

Extracting and Inlining Critical CSS

To extract critical CSS, you can use tools like Critical or PurifyCSS. These tools analyze your site’s HTML and CSS files and generate a smaller CSS file containing only the rules needed to render above-the-fold content. Once you have the critical CSS, you can inline it by adding a `<style>` tag with the critical CSS rules in your site’s `<head>` section:

        /* Critical CSS rules */

Defer Non-Critical CSS and JavaScript

Importance of Deferring Non-Critical Resources

Non-critical CSS and JavaScript are resources that don’t affect the initial rendering of your webpage. Deferring these resources means delaying their loading until the critical resources have been loaded. This can help reduce layout shifts by ensuring that your page’s layout is stable before any non-critical scripts or styles are applied.

Techniques for deferring CSS and JavaScript

To defer non-critical CSS, you can use the “media” attribute with a temporary value and then change it back using JavaScript once the page has loaded. For example:

<link rel="stylesheet" href="path/to/non-critical.css" media="print" onload="'all'">
<noscript><link rel="stylesheet" href="path/to/non-critical.css"></noscript>

For deferring non-critical JavaScript, you can use the “defer” attribute in your script tags:

<script src="path/to/non-critical.js" defer></script>

By inlining critical CSS and deferring non-critical CSS and JavaScript, you can minimize the impact of these resources on layout shifts and improve your site’s CLS score. This ensures a faster and more stable rendering of your WordPress site, contributing to a better user experience and higher search engine rankings.

Leveraging Critical Rendering Path Optimization for Better CLS

Understanding the Critical Rendering Path

The critical rendering path (CRP) refers to the sequence of steps a browser takes to process and render the HTML, CSS, and JavaScript of a web page. Optimizing the CRP ensures that your site’s content is displayed as quickly as possible, which can help minimize layout shifts and improve your site’s CLS score.

When the CRP is optimized, your site’s content is rendered more efficiently, reducing the likelihood of elements loading slowly or out of order. This can help prevent unexpected layout shifts and contribute to a better user experience.

Minimizing Render-Blocking Resources

Render-blocking resources are files, such as CSS and JavaScript, that must be loaded before the browser can render the page. By minimizing or deferring the loading of these resources, you can optimize the CRP and reduce layout shifts.

Techniques for Minimizing Render-Blocking Resources

Some methods for minimizing render-blocking resources include:

  • Inlining critical CSS: Include only the essential CSS needed to render the above-the-fold content directly in the HTML file, reducing the need for additional requests.
  • Deferring non-critical CSS and JavaScript: Use the `async` or `defer` attributes for non-critical scripts and the `media` attribute for non-critical CSS files to ensure they are loaded after the initial rendering.

Optimizing the Order of Page Resources

The order in which page resources are loaded can affect the CRP and your site’s CLS score. By optimizing the order of resources, you can ensure that critical content is loaded first, reducing the chances of layout shifts.

Some strategies for optimizing the order of page resources include:

  • Loading critical content first: Prioritize the loading of essential content, such as above-the-fold images and text, to ensure that users see meaningful content as quickly as possible.
  • Using the `preload` attribute: Apply the `preload` attribute to critical resources, such as fonts or images, to tell the browser to download them as early as possible.

By leveraging critical rendering path optimization, you can improve your site’s CLS score and overall performance. Techniques like minimizing render-blocking resources, and optimizing the order of page resources can contribute to a more stable and enjoyable browsing experience for your users, leading to increased user engagement, higher search engine rankings, and a more successful WordPress site.

Optimizing Server Performance for Better CLS

Importance of Server Performance

Connection Between Server Performance and CLS

Your server’s performance can have a significant impact on your site’s CLS score.

What Is The Best Web Hosting Provider?

Finding the best web hosting provider for your needs is an important step in optimizing your website. There's a lot to consider. Here are our basic recommendations:

Simple Websites

For simple websites, you have a lot of options. Most web hosts will do acceptably for a simple small-business website or blog.

That said, we recommend avoiding website builders so that you maintain control of your website.

VPS Hosting

If you just need a simple VPS, most providers will work well. Different providers have different downtimes, but the big differentiators are cost.

Providers like AWS and Google Cloud tend to be much more expensive than more specialized providers.

We recommend Digital Ocean and Hetzner if you're looking for a good VPS provider at a good price (it's what we use.)

High Performance Hosting

If you're looking for high performance web hosting, you're going to need something more specialized.

You can't just expect a simple cPanel host to give you what you'll need. You need a custom configuration.

Generally, you'll need either a managed host, or you'll need to get your servers configured with custom configurations.

If you're looking for a high performance hosting provider, we offer hosting designed for high-availability and high-traffic.

WordPress Hosting

What WordPress Hosting Should You Get?

There are many considerations when getting a WordPress hosting provider. Focus on the performance needs of your website.

WordPress Hosting Setup

When setting up your WordPress hosting, or switching hosts, there are a number of steps to complete. These include:

WordPress & Security

There are a number of WordPress security threats to contend with. We recommend using a plugin like WordFence to help secure your site.

WordPress Backups

Make sure to also back-up your site. It's absolutely essential, and ideally use an off-site backup provider that's different from your hosting provider.

WordPress Speed Improvements

There are a number of ways to improve the speed of your WordPress site on its hosting.

There are a number of plugins that can help improve your site's speed.


DNS Records

There are many different types of records, each with their own purpose. These include: SOA, A, TXT, CNAME, PTR (reverse DNS), and more. On some servers, you can also set up wildcard records.

The records you need will depend on what you're doing; WordPress sites require different records than mail servers, for example.


The process of your records transmitting to DNS servers around the world is called propagation. It normally takes 48 hours, but you can speed it up a bit with some planning.


To test your DNS records, there are 2 main tools: dig and nslookup. Each is very helpful in its own specialty.

Reliability & Security

There are a number of ways to improve your DNS reliability and security.

  • Split Horizon allows you to separate networks, either for intranets or for separating by geographic region.
  • GeoDNS allows you to give different records to different locations based on the requesting IP address. This allows you to create your own CDN, speeding up your site.
  • DNS over QUIC speeds up your DNS requests and gives you better DNS security by encrypting your DNS connection.
  • DNSSEC allows you to sign and encrypt your DNS connection, ensuring that nobody is changing your records.
  • DNS over HTTPS allows your visitors to request your DNS records over an encrypted connection.

Internationalized Domains

Internationalized domain names allow character encodings other than Latin characters. They have their own methods for backward compatibility.
