A few years back, we set out to find the most effective ways to enhance the loading speed of the Post Snippets website. That journey led us to realize the significant role that minimizing HTTP requests plays in improving load times.
Whenever a visitor lands on your site, their browser contacts your server, requesting various files necessary to render the page, such as images, CSS files, and JavaScript scripts. Each of these HTTP requests adds to the overall load time.
The more requests your site makes, the harder your server has to work, ultimately slowing down performance. This can negatively impact both user experience and search engine rankings. Therefore, you must know how to reduce HTTP requests, ensuring your site loads quickly.
In this blog, we’ll share actionable strategies for minimizing HTTP requests in WordPress and helping your site run faster.
Why Do We Need to Minimize HTTP Requests?
Each page on a WordPress site generally comprises multiple components. These may include images, stylesheets (CSS), JavaScript files, embedded videos, and more.
When a visitor accesses a page, their browser has to individually fetch and load each of these components to render the content properly. A page filled with numerous media files or scripts can significantly impact page loading speed.
Beyond the assets stored on your server, your site might also rely on third-party resources such as social sharing buttons, Google Analytics, or ad tracking pixels.
Although these external tools can add useful features and improve the overall user experience, they can also contribute to slower page load times if not properly managed.
A sluggish website can lead to user frustration, often resulting in visitors bouncing before the page has even finished loading.
Research from Strange Loop indicates that even a one-second delay can result in a 7% drop in conversions, 11% fewer page views, and a 16% reduction in customer satisfaction.
Minimizing HTTP requests in WordPress is a powerful technique to enhance site performance and is one of the most effective strategies to accelerate load times.
How Can We Find HTTP Requests
Before diving into ways to minimize HTTP requests in WordPress, let’s look at how to identify them.
The quickest method is to use your browser’s built-in developer tools. These tools display all the files your website loads when someone visits a page.
In Google Chrome, you can access these tools by clicking on View> Developer> Inspect, or simply right-click the page and select Inspect from the dropdown menu.
Head over to the Network tab. After reloading the page, you’ll see a complete list of loaded resources, which includes both internal and external HTTP requests.
To focus solely on third-party requests, use the ‘3rd-party requests’ filter. If you’re specifically interested in resources like JavaScript (JS) or Cascading Style Sheets (CSS) that can impact performance, use the filter buttons at the top to narrow down the list.
Pay close attention to resources that take longer to load. The Time column indicates the time it takes for each file to load fully. Clicking this column will sort the files by load time, and clicking again will reverse the order, putting the slowest ones at the top.
In the Initiator column, you may notice the name of a plugin or theme responsible for loading that resource. Take note of any plugins or themes contributing to slow-loading files.
External tools, such as Pingdom, can also provide a more in-depth analysis.
Now that you know how to recognize HTTP requests, let’s dive deep into the most effective ways to reduce HTTP requests in WordPress. This will help boost your site’s speed, improve SEO performance, and enhance the user experience.
- Merge JS and CSS Files
- Lazy Load Media (Videos and Images)
- Use CDN Tools
- Use Browser Caching
- Reduce External Resources Usage
Let’s get into it!
Combine JS and CSS Files
To reduce or minimize the number of HTTP requests your website makes, the most effective approach is to reduce the total number of files being loaded. By consolidating multiple files, you can streamline these requests without affecting your site’s functionality.
Take CSS files, for instance—rather than maintaining several stylesheets for different sections of your site, you can merge them into a single, comprehensive file. This way, the browser only needs to load one CSS file, significantly reducing the number of requests.
The same strategy applies to JavaScript files. Combining various scripts into a single file reduces the number of server calls required to power your site’s dynamic features.
There are also WordPress plugins that can automate this task. Notable ones include:
- WP Rocket (a paid tool)
- Autoptimize (a free option).
These plugins merge your files and handle minification. They strip out extra elements, such as whitespace and comments, from the code, shrinking the file size without impacting its functionality.
Due to minification, loading times become even faster since there is less data to transfer.
Lazy Load Media (Videos and Images)
Lazy loading is an effective method to enhance a website’s loading speed, particularly if the pages feature numerous images or videos.
Typically, WordPress loads every media file before displaying the full webpage, including those located further down that a visitor might not see immediately. This can cause a considerable delay in the initial page load.
By using lazy loading, images and videos are only loaded when they have to appear on the user’s screen, streamlining the loading process and enhancing performance.
Use CDN Tools
Leveraging a Content Delivery Network (CDN) tool is another powerful way to enhance your WordPress site’s loading speed, particularly for visitors who are geographically distant from your primary server.
Unlike earlier techniques, a CDN does not reduce the number of HTTP requests. Instead, it focuses on streamlining the way those requests are processed.
Typically, all your website’s files reside on a single server, meaning users worldwide must fetch data from that one spot. A CDN distributes copies of a website’s files across multiple high-speed servers positioned globally. The distribution ensures users receive data from the server nearest to their location.
Cloudflare is a prime example of a CDN tool.
Use Browser Caching
You can also make full use of browser caching to minimize HTTP requests to your site, particularly for repeat visitors who frequently access your pages.
When someone visits your site for the first time, their browser downloads essential assets, such as images, stylesheets, and JavaScript files. With browser caching enabled, these resources are stored locally on the visitor’s device.
On subsequent visits, the browser checks its local cache before requesting your server. If it finds a valid, unexpired version of a file, it loads the file from the cache instead of downloading it again.
This approach considerably decreases the number of HTTP requests sent to your server, resulting in faster load times for returning users.
That said, if your site’s content changes often, it’s crucial to set suitable expiration periods for cached files. This ensures that visitors eventually receive updated versions of your resources.
Reduce External Resources Usage
Many WordPress plugins and themes incorporate resources such as scripts, stylesheets, and images from third-party sites, including Google Analytics, Facebook, and various font providers.
These external HTTP requests can impact your site’s loading time, as the browser must connect to multiple servers to retrieve all the required elements.
Even if the external assets are well-optimized, relying on too many of them can still hurt your site’s speed and overall performance.
To minimize these external HTTP requests, begin by disabling and removing any plugins and themes that you don’t truly need.
It’s also a good idea to look for alternatives to plugins or themes that are known to load slow external files. You might have identified some of these earlier while analyzing HTTP requests.
When selecting essential WordPress plugins, pay attention to the external resources they utilize. Aim for options that emphasize speed and avoid those that unnecessarily load multiple external scripts or styles.
Bonus Tip: Enable Gzip Compression
A final and bonus suggestion is to enable GZIP compression to reduce file sizes on your web server. Although this doesn’t technically minimize HTTP requests, it significantly speeds up the transfer process, allowing your website files to load more quickly.
Ending Note
Excessive HTTP requests can significantly slow down a website, leading to poor page loading speeds. It’s crucial to implement strategies to address this problem. Apply the techniques mentioned above to reduce HTTP requests and observe if they improve your site’s overall performance.
