In the world of web development, optimising website performance is a constant endeavor. One crucial aspect of optimisation is avoiding the chaining of critical requests. When your WordPress website’s critical resources are linked in a way that causes delays in loading, it can significantly impact user experience. In this article, we’ll explore strategies to prevent the chaining of critical requests and ensure your website loads smoothly and swiftly.
Understanding Critical Requests
Before we delve into prevention strategies, let’s understand what critical requests are. Critical requests are resources that your website requires to load quickly for a seamless user experience. These resources include CSS, JavaScript, and fonts that are essential for rendering above-the-fold content (what users see before they start scrolling). Chaining occurs when one critical resource depends on another, causing a delay in rendering and slowing down the entire page.

Minimise and Optimise CSS and JavaScript
One of the key strategies to avoid chaining critical requests is to minimise and optimise your CSS and JavaScript files. Combining multiple CSS files into a single file and doing the same for JavaScript can reduce the number of requests made to the server. Additionally, minification, which involves removing unnecessary characters like white spaces and comments, reduces file size and enhances loading speed.
Load Above-the-Fold Content First
Prioritising the loading of above-the-fold content is essential. This means that critical resources required to display the visible portion of the page should be loaded before anything else. To achieve this, consider using the “defer” attribute for non-essential JavaScript files. This allows the browser to continue parsing HTML without waiting for JavaScript files to fully load, preventing the chaining of requests.
Utilise Browser Caching
Browser caching is a technique that stores resources locally on a user’s device, allowing subsequent visits to your website to load faster. By specifying how long resources should be cached, you reduce the need for repeated requests to the server. Utilise caching plugins available for WordPress to enable browser caching for CSS, JavaScript, and other critical resources.
Implement Asynchronous Loading
Asynchronous loading is a method that allows resources to load simultaneously without blocking each other. Asynchronously loading critical JavaScript files, for instance, ensures that they don’t hinder the loading of other resources. This prevents chaining and results in faster page rendering. However, exercise caution when implementing asynchronous loading to ensure that scripts don’t interfere with each other’s functionality.

Consider Using Content Delivery Networks (CDNs)
A CDN is a network of servers distributed globally that deliver cached static content from the server closest to the user. CDNs can reduce the physical distance between your server and users, leading to faster loading times. Many CDNs also offer optimisation features, such as minification and compression, further enhancing critical resource delivery.
Regularly Monitor and Test
Optimising critical requests isn’t a one-time task; it requires continuous monitoring and testing. Regularly assess your website’s performance using tools like Google PageSpeed Insights or GTmetrix. These tools provide insights into how resources are loaded and offer suggestions for improvement.

Conclusion
Chaining critical requests can significantly hinder your WordPress website’s performance and user experience. By adopting strategies such as minimising and optimising CSS and JavaScript, loading above-the-fold content first, utilising browser caching, implementing asynchronous loading, and considering CDNs, you can prevent these delays. Remember that the key is to prioritise the swift delivery of critical resources for a seamless user experience. By investing time and effort into optimising critical requests, you’ll create a faster, more responsive, and user-friendly WordPress website.
