What is Render Blocking Resources? – How to Remove, and More

What is Render Blocking Resources?

Render blocking resources are bits of code in website files, usually CSS and JavaScript, that prevent a web page from loading quickly.

These resources take a relatively long time to load. Long to render for the browser, but may not be necessary for immediate user experience.

Rendering can suppress or delayed until the browser needs to generate. Don’t get me wrong: CSS and JavaScript are significant.

Without JavaScript, we would not add dynamic, interactive, and attractive elements to our websites. But, if they execute at the wrong time, CSS and JavaScript can negatively affect your website’s performance.

How to Remove Render Blocking Resources in WordPress?

1. Identify the Resources that Block Rendering

Before making any changes, you must first locate the Resource processing lock. The best way to do this is to use a free online speed test like Google PageSpeed ​​Insights Tool. Paste your site URL and click Analyze

When the analysis is complete, Google gives your website an overall speed score from 0 (slowest) to 100 (fastest).

A score between 50 and 80 is average, so you’ll want to land at the top of that range or higher.

To identify render-blocking files that are slowing down your page, scroll down to Opportunities, then open the accordion Remove render-blocking resources.

You will see a list of records that slow down the “first paint” of your page; These files affect all content loading time that appears in the browser window when the page load for the first time. It is also known as “top half of the page” content.

Be aware of files that end in .css and .js extensions, as these are the ones you’ll want to focus on it.

2. Clear Locked Resources Do not Render it Manually or with a Plugin.

Now that you have known the problem, there are two ways to fix it in WordPress: manually or with a plugin. First, we have the complement solution.

Various WordPress plugins can reduce the effect of rendering-blocking resources on WordPress websites. I will cover two popular solutions, Autoptimize and W3 Total Cache.

Autoptimize is a free plugin that modifies files on your website to provide faster pages. Automatic optimization works by adding files, minimizing code (that is, reducing the file’s size by removing redundant or unnecessary characters), and delaying loading resources that block rendering.

Since you are modifying your site’s backend, remember to be careful with this plugin or any similar plugin. To remove resources blocking processing with automatic optimization:

• Install and activate the Autoptimize plugin.
• In your WordPress dashboard, select Settings> Auto Optimize.
• Under JavaScript Options, checkered the box following to Optimize JavaScript code.
• If the box next to L ‘Is the JS file aggregation? If checked, uncheck it.
• Under CSS Options, checkered the box next to Optimize CSS code?
• If the box next to Add CSS files? If checked, uncheck it.
• At the lowest of the page, click Save Variations and Clear Cache.
• Analyze your website with PageSpeed ​​Insights and look for an improvement.
• If PageSpeed ​​Insights still reports that JavaScript files block rendering, go back to Settings> Auto Optimize and check the boxes next to JS files added? And added CSS files, then click Save changes and clear cache, and rerun the scan.

3. Run a Site Scan Again

• After making the changes, do a final analysis of your website through PageSpeed ​​Insights and see the impact of your changes on your score.
• There is a notable improvement, but don’t worry if it isn’t. Many factors can affect page performance, and you may need to dig deeper to find the source of common hand piercing.

4. Look for Errors on your Website

• In addition to re-crawling, check your pages to make sure your site is working. Does the page load correctly? Do all the elements appear? If something is broken or doesn’t load properly, undo the changes, and fix the problem.
• It has reached a point where you have repeatedly tried other ways to speed up your pages instead of risking breaking your site.
• Many factors donate to your users’ experience on your website, but few are more critical than load time. Whenever you make significant changes to your WordPress site’s content or appearance, you should always consider how those changes affect performance.
• Now that you have removed the render-blocking features, you need to continue optimizing your website—speed by looking at other components known to reduce performance.
• Try to incorporate periodic speed tests into your site maintenance program; anticipating any potential problems will be critical to your success.
