When visitors land on your website, their browser attempts to download and execute every single JavaScript file—like Google Analytics, chat widgets, and tracking codes—before it finishes displaying the actual content of your page. This "render-blocking" behavior can cause severe delays, frustrating users and significantly lowering your performance scores. By delaying the execution of these non-essential scripts until the visitor actually interacts with the page (such as scrolling or moving the mouse), you can achieve near-instant initial load times.

Since your Sternhost account is powered by LiteSpeed, you can automate this powerful Core Web Vitals optimization safely in the background using your existing caching plugin.

Step 1: Navigating to the JS Settings

You can easily manage how JavaScript loads on your server without touching any code.

• Log in to your WordPress admin dashboard.

• In the left-hand sidebar, hover over LiteSpeed Cache and click on Page Optimization.

• Click on the JS Settings tab located at the top of the settings screen.

Step 2: Activating JS Delay

Once you are in the JavaScript settings, you can enable the delay feature to instantly prioritize your visible content.

• Scroll down the page until you locate the setting specifically labeled 'Load JS Deferred'.

• Change this setting from its default state to 'Delayed'.

• Scroll to the very bottom of the page and click the Save Changes button to apply the configuration.

Why Delaying JavaScript is Essential

• Eliminates Render-Blocking: Your website's text and images will load immediately because the browser is no longer forced to process heavy third-party scripts first.

• Boosts Mobile Scores: Mobile devices have less processing power than desktop computers, making delayed execution one of the most effective ways to improve mobile speed test results on tools like Google PageSpeed Insights.

• Prioritizes User Experience: Heavy features like live chat widgets only load when the user actually starts interacting with the page, ensuring they do not interfere with the initial visual presentation.
