Includes:

Performance & Speed: load assets from a global CDN

The Site Accelerator feature helps your site load faster by serving your images and static files from Jetpack’s global content delivery network (CDN).

Why use it:

  • Reduces load on your server
  • Speeds up image-heavy pages
  • Improves loading times by serving files from data centers near your visitors

You can choose to accelerate image delivery, static file delivery, or both. These options are available in the Jetpack plugin under the Performance tab at Jetpack → Settings

Caching: speed up repeat visits

Jetpack Boost includes a built-in page caching feature that stores and serves full versions of your pages for logged-out visitors. This helps reduce server load and significantly improves load times on repeat visits.

Why use it:

  • Faster page load times for returning users
  • Reduced server and database usage
  • Automatically clears cache when content is updated

Jetpack Boost’s caching works out of the box for most sites. You can also customize it with filters, adjust cache duration, exclude certain pages from caching, or enable logging for debugging.

If you need advanced caching features or your hosting provider prevents Boost’s cache from activating, you can use WP Super Cache for more control.

Why use it:

  • Reduces load on high-traffic or dynamic sites
  • Improves load speed for returning visitors
  • Offers advanced configuration beyond what’s built into Jetpack Boost
