Render-blocking resources, including the scripts, stylesheets, and HTML imports, block the rendering of visual elements to the screen. When render-blocking resource occurs, a website may witness a slow initial page load, delay in interactivity, a blank or partially rendered page, and more.
Render-blocking resources can be both critical and non-critical. A critical one is required for a web page to render important content, while a non-critical one can interrupt page load time.
As a result, businesses must be able to identify the difference between these two types of render-blocking resources to find the best solution to minimize the risk of render-blocking.
How do render-blocking resources affect website performance?
The first issue that render-blocking resources most affect is the interruption in the website rendering process. When there are render-blocking resources on the website, the browser has to download and execute these resources before other processes can continue.
Hence, the rendering time of a web page can be extended as it has to wait until this scheme is finished. The extension in time can result in slower page load time and poor user experience.
More than that, the render-blocking resources can also affect customers’ page load time. When entering a website, users often evaluate its efficiency depending on its speed and the time to display visual content.
Consequently, if a website struggles with render-blocking issues, its perceived load time will also increase. Undoubtedly, this issue can frustrate users and give rise to bounce rates.

Google Chrome DevTools
Google Chrome DevTools is a powerful collection of website development and debugging gadget attached to the Google Chrome browser.
This tool has many features and uses, such as a Network panel with the ability to display loading order resources, or an Audits panel, with the potential to carry on an audit and highlight render-blocking resources.
PageSpeed Insights is a tool developed by Google that has many usages, including recording and analyzing web page performance and providing suggestions for improvement solutions. This tool can recognize and indicate render-blocking resources among many different performance-related issues.

Lighthouse is an open-source application integrated into Google Chrome’s Developer Tools. This application automatically allows the user to examine a web page’s performance, accessibility, and SEO. Lighthouse can also outline render-blocking resources and advise solutions for each problem.
WebPagetest is a free online tool that enables users to observe their website performance, regardless of location and browsers. This online tool can also develop a flying bricks chart that displays the loading order of resources, making recognizing render-blocking resources much easier.
Another popular online web performance testing tool is GTmetric.
This tool also has the potential to provide users with detailed insights into its loading speed. It can offer a business flying brick charts as well as a breakdown of resources about its web page performance.

8 key strategies to eliminate render-blocking resources
Render-blocking resources may waste businesses’ time, money, and efforts if the problems are not taken seriously.
However, businesses can minimize the risk of render-blocking resources as well as make the process of removing this issue more easily by consulting 8 key strategies to eliminate render-blocking resources below:
1. Analyze root cause
Analyzing the root cause is the first and foremost thing that should be done before tackling any problems. This is one of the best ways to identify and have a specific overview of what is happening.
By analyzing the main reason for render-blocking resources, you can make a great decision in solving problems and improving your page Core Web Vitals.
One of the most common solutions to removing these render-blocking resources is to do it manually. However, this can only be an ideal option if the person taking charge of removing render-blocking resources is an experienced coder.
3. Implementing browser caching and CDN
Implementing browser caching and Content Delivery Networks (CDN) can be a great option when eliminating render-blocking resources due to their positive impacts.
Consequently, this will remove render-blocking resources as the number of requests is decreased, and the time for these resources to be downloaded is also eliminated. Take a look at Magento 2 Block Cache for further approaches to caching.
When the user requests the web page, the cached resources closest to the user will be displayed, thus reducing the discontinuation and network congestion. More importantly, this also prevents the user’s browser from waiting to download render-blocking resources from the origin server.
4. Prioritize critical resources
Prioritizing critical resources can be a key solution because it can hold a high commitment that only essential resources required for rendering visible parts of the webpage are loaded and processed in advance.
As the browser can render and display above-the-fold content quickly and efficiently, users will immediately see the website’s fast loading speed. More than that, by prioritizing critical resources, the impact of render-blocking resources can be eliminated or minimized. The necessary styles and scripts will be prioritized to be loaded and rendered first, resulting in the website’s interactivity and usability for users.
It is undeniable that this approach is beneficial for a web page in numerous ways, such as enhancing perceived loading speed, quick user interaction with vital parts of the page, and more.
Furthermore, this can speed up the loading process, especially for resources that are not directly critical for the initial rendering of the page. With asynchronous loading, the browser can retrieve the resources without waiting for one resource to finish before starting the next, reducing the overall loading time.
7. Evaluate third-party scripts
Evaluating third-party scripts can contribute to the process of removing render-blocking resources by recognizing and eliminating unnecessary or poorly optimized scripts that harm the rendering process.
You can start examining third-party scripts by reviewing and assessing the necessity of third-party scripts on your website. Each additional script can have its tangible render-blocking resources and affect web performance. Remember to keep the essential scripts for your site’s functionality.
By evaluating third-party scripts, the root causes contributing to render-blocking resources will be identified and addressed more efficiently.
8. On-going test and measure of performance
Ongoing tests and performance measures can help eliminate render-blocking resources by providing an overall report into the contemporary state of the web page’s loading speed as well as recognizing specific areas that need to be optimized.
Insights, GTmetrix, or WebPageTest. These tools will provide detailed insights and recommendations for further optimization.
By ongoing testing and measuring performance, you will gain valuable insights into the effect of render-blocking resources on your website. This process also ensures that informed optimization decisions, and progress tracking are made to the website, and optimal web loading speed is maintained by removing or minimizing the impacts of render-blocking resources.
Undeniably, render-blocking resources have many negative impacts on website performance, such as slower page loading time, increase in bounce rate, poor user experiences, and more.
Consequently, businesses should focus on tracking and eliminating render-blocking resources as it is the most efficient way to reduce the impact of this issue and rocket their website’s traffic and sales.
