CSS loading optimization

The browser first downloads and parses CSS files before showing the page we’re looking for. This causes CSS a render-blocking source. Big CSS files can be problematic in poor network conditions. This is where Jetpack Boost comes in work.

Jetpack Boost generates critical CSS for a website’s homepage, posts and pages. This allows contents to show up on the screen much faster, regardless of both the screen size & internet speed. This is particularly very helpful for viewers of a website using mobile devices.

Non-essential JavaScript deferring

When a third-party script slows down page loading on a website, you either have to remove the script entirely depending on the value it provides to the site or optimize the loading process.

The Non-essential JavaScript Deferring feature of Jetpack Boost fixes problems by showing scripts late. It moves some tasks to after the page loads. This way, important visual information can be seen sooner. 

Lazy Loading Images

Lazy loading is proved to be one of the most promising optimization processes for any website. Jetpack Boost does just that, but easily.

When the Lazy Loading Images feature is enabled, only the images the user can see will be loaded. As the user scrolls, images are loaded just before they show up on the page. This optimization may sound simple, but it makes sites faster. Besides, it saves bandwidth for both your host and your customers.
