Simple WordPress Speed Improvements You Can Do via Preloading

Key Takeaways

• Slow WordPress sites lose visitors fast, as 40% leave after 3 seconds load time.
• Preloading speeds up sites by loading critical fonts, CSS, images, and scripts early.
• LCP, INP, and CLS impact SEO; preloading improves these vital performance scores significantly.
• Resource, cache, and link preloading optimise speed by preparing assets before the browser needs them.
• Cloudways’ Breeze plugin enables easy preloading without coding or installing extra performance plugins.

If you are here, you are either thinking of building a WordPress website or you want to revamp your existing website. In either case, WordPress speed optimization is the key to hugely enhancing user experience, consequently leading to high conversion rates.

Not convinced? Let’s look at the numbers.

3 seconds. Yes, Kissmetrics research suggests that’s how long  40% of visitors will wait before abandoning a slow-loading website. Imagine, that is almost half your traffic gone before they even go through your offerings.

Suppose you build a WordPress site. Maybe it’s a blog that has a good amount of visitor traffic. Maybe it’s your ecommerce store. Everything is going fine, until it’s not.

You notice that pages take a little too long to open. Fonts flicker before settling. Images pop in awkwardly. Your bounce rate climbs up while your ranking keeps going down.

The truth is, your browser is working blind.

It is discovering critical files only when it gets to them, downloading them one by one, and rendering content in small sections. Unfortunately, this lag is enough to drive users away and hurt your Core Web Vitals.

That’s where Preloading comes in.

In this article, our WordPress expert will help you discover how preloading resources in WordPress works, which assets to prioritize, and the tools (including plugins) for easily achieving WordPress speed optimization. Plus, those of you looking for superior WordPress hosting will learn how using Cloudways Hosting can take the hassle out of the entire process.

Before getting into the nitty-gritty of Preloading, it’s important to figure out exactly why your website needs to be fast.

Why Speed Matters for WordPress Websites

Website visitors don’t wait for websites to load. In case your WordPress site is slow and taking more than a couple of seconds to load, most users will bounce and probably never come back. You are not just irritating visitors, you are also bound to lose leads, rankings, and money, without even realizing it.

To understand this better, you need to know about Core Web Vitals.

Optimize WordPress Core Web Vitals

These are important metrics that Google offers to help website owners get a clear picture of what a fast, user-friendly site actually looks like in practice. Core web vitals are a critical part of WordPress speed optimization. In fact, these metrics are measurable data points that directly impact your website’s search visibility and ranking on SERPs.

It includes:

• LCP (Largest Contentful Paint) 

LCP measures the load time of the main content (like a website’s hero image or heading) is measured. Typically, when these elements take time to load, your users feel like your site is stuck. Preloading serves a vital function by ensuring that these sections appear immediately.

• INP (Interaction to Next Paint) 

INP is designed to track how responsive your site is when someone interacts with it (by clicks, key presses, or taps). Without early loading of these script files, the user experiences lag. Preloading eliminates this lag.

• CLS (Cumulative Layout Shift) 

This metric checks how stable your website layout is as it loads. Fonts and images loading late can cause everything to jump, but preloading prevents this from happening early on.

To put it simply, Core Web Vitals are Google’s way of measuring real user frustration. Preloading reduces that frustration before it even begins, making it a vital aspect of businesses struggling to improve WordPress performance.

Fast Sites Are Easier to Crawl

You may not realize it, but search engines don’t just automatically understand your site. They have to crawl it, line by line. So, the faster your site loads, the easier it is for Googlebot to get through more pages. Google suggests that your website’s Time to First Byte (TTFB) should be 200 milliseconds or less. TTFB the time it takes for your browser to get the first bit of data from the server.

And here’s the part many forget: if your site is slow, not all your content may even get indexed. That translates to fewer opportunities to rank, fewer people finding you, and fewer chances to convert.

Preloading is a top WordPress speed optimization tactic to fix all this.

Thanks to Preloading, these issues do not even arise, as it decreases the waiting time of the browser.

What is Preloading and Why It Helps

What Is Preloading and What’s The Point of Preloading Resources in WordPress

Preloading is similar to giving the browser a heads-up: “Hey, you’re going to need this, so grab it now.” Basically, it instructs the browser to download key resources ahead of time before they’re even asked for.

The above image shows the browser hint that enables resource loading prioritization.

That means things like images, fonts, CSS, or JavaScript files are ready and waiting when the page is built. Think of it like prepping ingredients before you start cooking. When you ignore prep, everything takes longer and feels frustrating.

By preloading resources in WordPress, anyone who comes to your website will get the impression that it is fast, smooth, and professional.

Types of Preloading 

Three primary resource hints come into play in web optimization.

Type of Preloading	What It Does	When It Happens	Use Case Example	Tools/Plugins (WordPress)	Benefits
Resource Preloading	Loads critical assets (fonts, CSS, JS) early by instructing the browser via HTML <link rel=”preload”>.	During the current page load.	Preload a custom font before it blocks rendering.	WP Rocket, Perfmatters, manual code in <head>	Faster paint, improved Core Web Vitals (esp. LCP).
Cache Preloading	Pre-generates and stores static versions of pages in cache, so users don’t have to wait for first-time generation.	After cache is cleared or scheduled periodically.	Regenerate cache for all blog posts after a plugin update.	WP Rocket, LiteSpeed Cache, W3 Total Cache	Faster first visit, reduced server load.
Link Preloading (aka Page Preloading)	Predicts user navigation and preloads internal page content when the user hovers or scrolls near a link.	Before user clicks, often triggered by hover.	Hovering over a “Contact” link preloads that page’s content.	Flying Pages, Instant.page	Instant-like navigation, better perceived speed.

• Resource Preloading

Website elements like CSS, fonts, images, and JavaScript are considered critical resources. Rather than waiting until the browser finds them during page load, they are loaded in advance. This boosts the speed of rendering above-the-fold content (the portion of a webpage that is visible to a user without requiring them to scroll down) and helps ensure that the layout remains stable. However, it goes without saying that preloading too many unnecessary resources, will negate all your efforts anyway.

• Cache Preloading

Visitors can have a smoother journey on your WordPress website when you have already anticipated what they will need. That’s cache preloading. In WordPress caching, all the commonly visited or critical pages are pre-rendered and stored in cache, enabling them to load instantly on the next visit. As you guessed, it is especially useful when it comes to repeat visitors or pages that are frequently updated (the content in the cache gets automatically updated).

• Link Preloading

When someone is reading one page on your website, the browser can preload assets for the page they are most likely to visit next. If a visitor hovers over your webpage link, there is a wait of approximately 100 milliseconds before that page’s HTML is loaded in the background. To improve WordPress performance you can leverage link preloading for internally linked pages, as user behavior for these assets is quite predictable.

Now that we have covered what preloading is and its various types, let’s imagine the scenario of WordPress websites that do not use preloading.

What Happens Without Preloading in WordPress

• Slow Initial Load

Without preloading, the browser strictly follows the loading sequence and waits for resources to be discovered. What results are visible delays (visitors hate this) before anything really useful shows up on screen.

• Unstable Page Layouts

You must have noticed parts of the page jumping around when the fonts or the images load late. Buttons shift, text is misaligned, and users become frustrated.

• Bounce Rate Increases

It’s not surprising that sites that are not preloaded have very high bounce rates. If someone comes across a site that stutters or lags during the first few seconds they leave and go to your competitors.

• Poor User Experience on Mobile

From your own experience, you may have realized that mobile networks tend to be slower and less reliable than WiFi. Mobile visitors to your site suffer the most, seeing half-loaded pages or blank spaces before anything meaningful appears.

It’s very clear that a WordPress site that does not use preload faces several challenges. So, now, let’s see the advantages of preloading resources in WordPress.

What Are the Benefits of Preloading Resources in WordPress?

• Better Page Load Times

When essential assets are preloaded, it speeds up the most in-demand parts of your site. This creates a short and sweet experience, which directly increases engagement.

• Improved SEO Scores

Google is known for rewarding fast-loading sites. With preloading in place, your site meets more Core Web Vitals benchmarks. How does that help? This allows it to get much higher visibility in search results.

• Higher Conversion Rates

Faster website loading times make visitors happy (they may not even realize it). This prompts them to carry out actions like adding items to a cart, filling forms or making bookings, thus boosting conversion.

• Less Server Load

By smartly preloading and caching assets, you cut down on redundant round-trips between the browser and the server. That conserves bandwidth and enhances server productivity.

Now, let’s look at the specific elements in your WordPress website that need to be loaded first.

Which Elements To Preload First To Speed Up WordPress Load Time

Element	What to Preload	Why It Matters
Fonts	Key site fonts	Prevents font delays and layout jumps
Critical CSS	Styles for above-the-fold content	Ensures styles show instantly, avoids blank screens
Critical JavaScript	Scripts controlling visible interactions	Makes buttons, sliders, and menus respond instantly
Hero & Above-the-Fold Images	Main banner and first-screen images	Displays key visuals immediately, boosts first impressions

When it comes to WordPress speed optimization, site owners need to begin by preloading certain critical assets before others.

These include the resources that directly affect what users see and interact with first, and it is mainly above-the-fold content.

Faster WordPress Starts Here

With our optimized WordPress hosting, features like preloading make your site load quicker and keep visitors engaged. Enjoy speed and reliability built in.

Get Started

Hero Images and Above-the-Fold Images

Even if a page has loaded in 2.5 seconds, a person may perceive the loading time to be 4 seconds. This is termed perceived loading speed. Website elements like the hero image and images above-the-fold need to appear instantly or visitors may lose trust in the site and leave. Preloading makes this happen, keeping them engaged from the instant they land on your website.

Fonts

Source

As you can see, the webpage of this site is showing a flash of unstyled text, as the web fonts or Google Fonts are not loaded yet.

Fonts, especially customized ones, tend to block rendering since the browser will not render (display) the text until the font has been loaded. That’s why sometimes users experience empty spaces or flashes of unstyled text. Preloading fonts ensures they are loaded early, stabilizing the layout and making your site feel polished from the very beginning.

Critical CSS

Source

The image above is an example of what happens when Critical CSS is not preloaded.

There are certain above-the-fold styles that need to be loaded first, before other portions of the page.

Without it, users would see a blank white screen or content that looks unstyled. Preloading critical CSS means that your site’s visual layout appears correctly in the first instance, rather than constructing itself gradually before their eyes.

Critical JavaScript

Certain scripts manage some key interactions of visitors on the page, such as menus, sliders, or call-to-action buttons. Let’s say a shopper taps on the ‘Buy Now’ button and nothing happens. That means the button’s functionality is not yet loaded. Preloading this JavaScript makes your interactive elements react immediately, making your experience smoother and more reliable.

Using Cloudways WordPress Hosting to Simplify Preloading Setup

Do you want to boost speed with WordPress plugins?

Well, if you plan to host your WordPress site on Cloudways, you would not have to worry about gathering a bunch of different tools to manage performance. It offers built-in options for preloading, caching, and content delivery that work together without much setup required. Ensuring your WordPress user roles are correctly configured also helps maintain control over these settings, so only the appropriate users can make changes to critical performance features.

This way, you avoid plugin conflicts and also ensure that optimization efforts are easy to manage.

Cloudways Breeze Cache Plugin

If you’re using Cloudways, Breeze is already part of the package. You can enable preloading for fonts, minifying assets, and even setting up browser caching from a simple dashboard. It’s meant to give you results without needing to adjust too many settings. Most people leave it on and let it do its job.

Source

As you can see, Preloading can smoothly be done on the user-friendly Breeze dashboard.

• There’s a cleanup tool built in that helps clear out things like old post drafts or spam comments that slow pages down.
• It also compresses your site’s files using GZIP, which basically means your content travels faster without losing quality.
• If a specific page or plugin is faulty, Breeze is able to skip caching it. This is needed particularly when you are still tweaking your pages.
• Breeze works with Cloudways’ Varnish cache too, so you get another performance boost without needing to set anything up manually.

Cloudflare CDN

Once you connect Cloudflare through Cloudways, your website files will not all come from one location anymore. Servers that are physically closer to your visitors will deliver the files. That makes your site feel quicker, especially for clients outside your hosting region. The best part? After the initial setup, it just keeps working in the background without much effort on your part.

• All your common files, like your images and stylesheets, are stored to ensure that returning visitors get a smooth flowing experience as the resources are already downloaded.
• Because Cloudflare handles so much of the traffic itself, your actual server will not be under as much pressure during high-traffic periods.
• You can clear the cache manually in Cloudflare, if you have updated something and want everyone to see the latest version right away.
• In the background, it filters out spam traffic and bots before they even reach your site, which means fewer headaches on your end.

Preloading Plugins to Use on WordPress

Those of you who are not developers but still want to make your WordPress site load faster can check out these popular plugins that handle the complete preloading process for you. These tools let you prioritize important files like fonts, CSS, and scripts, enabling high-level WordPress speed optimization.

Some WordPress speed plugins you can try include:

WP Rocket

WP Rocket takes care of preloading automatically after it has been activated. Your homepage and sitemap URLs are fetched in order to generate cached versions. Plus, since it preloads fonts, they are ready before the page even starts rendering (displaying). You will not need to go through complex settings, as it’s designed to give results with minimal input.

Perfmatters

Perfmatters gives you control over exactly which files get preloaded and which ones don’t load at all. So, you can disable things like emoji scripts, block editor styles on the frontend, or Google Maps if you’re not using them. One of its preload fields allows you to manually add specific files like custom fonts or CSS.

Asset CleanUp

This plugin scans each page and shows you a list of all the CSS and JavaScript files being loaded. If needed, you can turn off the ones that are simply not needed (elements like contact form scripts that appear on every page even if the form is only on the Contact page). You can also manually preload files like your main stylesheet or a custom font that’s slowing down the first paint (i.e. when the first visible pixels start to load on the screen).

Pre Party Resource Hints

Pre Party gives you fields to add preload, prefetch, and other browser instructions from your WordPress dashboard. For example, you can tell the browser to fetch your main font file early or prepare an image for loading before it’s visible. It’s a helpful plugin, especially if you want to optimize how your pages load, one resource at a time.

Performance Gains: Case Studies, Results & What to Expect

Among the vast number of agencies that have relied on Cloudways for their WordPress projects, here are two cases that stand out in terms of super-fast website performance and all the benefits attached to it.

Case Studies

WPFlat™

A Nigerian-based WordPress agency, WPFlat™, was on the lookout for a reliable and scalable hosting solution to speed up their clients’ websites. Cloudways Hosting took over the project and enabled drastic improvements in WordPress performance.

The results have been tremendous. The clients’ WordPress websites became 2x faster, traffic increased by 20%, and load times dropped by 50%. Cloudways leveraged its built-in Breeze plugin to handle cache preloading and file delivery, allowing it to stay ahead of its competitors.

Pioneer Media

Tennessee-based web design agency, Pioneer Media, was struggling with slow website performance and time-consuming maintenance tasks. They approached Cloudways Hosting for their expertise in WordPress speed optimization, and the results were incredible.

What’s the proof? 1 second. That’s how fast their websites’ pages now load, when they previously used to take 3–6 seconds to load. Speed improved 5x, and Pioneer Media’s profit margins jumped to 92% from hosting alone. Plus, thanks to Cloudways managed cloud hosting, preloading became effortless too, helping critical assets load faster, and amping up the overall user journey.

Final Thoughts

The fact is that a lot of WordPress sites load slowly, not because they are faulty, but because browsers are not told what to prioritize. This hampers user experience. If your site’s user experience is negative, you cannot honestly expect any good results.

It’s true that there are several other WordPress speed optimization tactics out there, but preloading is one of the most direct and impactful ways to improve how quickly your site shows up for visitors.

Thinking of using preloading to improve your WordPress websites’ performance? The good news is, you don’t need to know code to use Cloudways’ Breeze plugin. It’s already included with every WordPress site on Cloudways, so you can turn it on and see results without having to set anything up manually.
