How to Eliminate Render-Blocking WordPress: 5 Minutes Guide

Are you tired of waiting for your website to load, only to be greeted by a frustratingly slow loading time?

Well, fear no more because we’ve got just the solution for you! In this article, we’ll explore eliminating render-blocking resources in WordPress to improve site speed and enhance the visitor experience, eliminating elements preventing quick rendering.

So, grab a cup of coffee, sit back, and get ready to optimize your WordPress site like a pro. Let’s jump right in!

What are render-blocking resources?

Render-blocking resources are external files for web pages to render content but delay the process. These resources, like CSS and JavaScript, require fetching, parsing, and execution before the browser can continue rendering.

When a browser encounters a render-blocking resource, it halts the rendering process, fetches the resource from the server, and then processes it. This can introduce delays in rendering the visible content of the page, leading to slower page load times and a poorer user experience.

Common examples of render-blocking resources are:

• External CSS files. CSS files define web page elements’ appearance and layout, but render-blocking causes browsers to wait for fetched and parsed files before correct rendering.

• JavaScript files. JavaScript, a dynamic programming language, can cause delays in web page rendering if render-blocking files are executed by the browser.

Importance of eliminating render‑blocking resources in WordPress

It is essential to get rid of render-blocking resources in WordPress if you want to improve your website’s functionality and user interface. Here are the key reasons why it’s important:

• Faster page load times. Render-blocking resources slow down rendering, causing delays in content display. So, eliminating or minimizing their impact improves web page load times, leading to better user satisfaction, engagement, and lower bounce rates.

• Improved user experience. Eliminating render-blocking resources on WordPress sites ensures quick loading and a smooth user browsing experience. This prevents partially loaded pages and delays critical content display.

• Search Engine Optimization (SEO) benefits. Optimizing WordPress site performance and eliminating render-blocking resources boosts search engine rankings, organic traffic, and visibility by improving user experience and optimizing performance.

• Mobile optimization. Optimizing WordPress sites for mobile devices is crucial due to high latency and limited bandwidth, which reduces bounce rates and improves conversions.

• Increased conversion rates. A faster, responsive website boosts conversion rates by enabling users to access content, navigate, and complete actions. So, eliminating render-blocking resources and optimizing performance improves business outcomes.

Therefore, to deal with how to eliminate render-blocking resources WordPress, we can employ various techniques like minifying, asynchronous loading, caching, and performance optimization plugins and themes for improved performance.

How to find render-blocking resources in WordPress?

Regardless of the status of your website, the initial step is to locate any render-blocking resources and determine the appropriate course of action. Thankfully, there are several methods at your disposal for accomplishing this.

Here are the two most popular methods you can use to identify render-blocking resources in Wordpress:

Using web performance optimization tools

Free and paid tools offer detailed insights into website performance, including the ability to identify render-blocking resources. Common options include:

• Google PageSpeed Insights: This free tool by Google analyzes your website and offers suggestions for improvement, including highlighting render-blocking resources in the “Opportunities” section.
• GTmetrix: This free tool also analyzes website performance and provides a “Lighthouse” audit that specifically identifies render-blocking resources.
• WebPageTest: This free tool offers a waterfall chart that visually depicts how resources are loaded on your website. This can help you identify render-blocking resources by looking for loaded resources before the initial page render.

Analyzing network requests in developer tools

Most modern browsers have built-in developer tools that allow you to analyze network requests made by your website. Here’s how to find render-blocking resources using developer tools:

• Open your website in your preferred browser.
• Right-click anywhere on the page and select “Inspect” or “Inspect Element” (depending on the browser).
• Move to the “Network” tab in the developer tools.
• Look for resources with the “Blocking” type in the “Type” column. These are the render-blocking resources on your website.

How to eliminate render‑blocking resources WordPress manually?

To manually eliminate render-blocking resources WordPress, you’ll need to modify your theme’s files or use plugins specifically designed for this purpose. Here’s a step-by-step guide:

Step 1: Locate the render-blocking resources

You need to identify the CSS and JavaScript files mentioned in the analysis report. Typically, these files are enqueued in your theme’s functions.php file or within individual template files.

Step 2: Move CSS files to the header

To countinue the process of eliminating render-blocking resources WordPress, you need to open your theme’s header.php file and locate the <head> section. Find the enqueued CSS files and move them from the footer (where they are usually located) to the header. Use the wp_enqueue_style function or the wp_head action hook to enqueue the CSS files.

Step 4: Defer JavaScript loading

Open your theme’s functions.php file and find the section where JavaScript files are enqueued. Replace the wp_enqueue_script function with the wp_enqueue_script('handle', 'source', array(), false, true); format. This loads the script in the footer and defers its execution.

Step 5: Minify and combine files

You can minify and combine CSS and JavaScript files to further optimize your website. There are plugins available, such as Autoptimize and W3 Total Cache, that can handle this automatically. However, manual minification and combination should be done cautiously, as it may require more advanced knowledge.

Step 6: Test and validate

After making these changes, test your website thoroughly to ensure everything functions as expected. Check that the render-blocking resources have been successfully eliminated by re-running the analysis using the tools mentioned in Step 1.

Remember to take a backup of your theme files before making any modifications. If you’re not comfortable editing code manually, you can also consider using caching and optimization plugins that offer options to eliminate render-blocking resources automatically.
