Accelerate Your Site and SEO With Jetpack

An illustration of a site loading quickly with Jetpack

Regardless of the type of site you’re running, making sure that it loads quickly and feels fast should be among of your primary goals.

A fast site means a better visitor experience. Shorter load times can lead to lower bounce rates, happier readers, more page views, a healthier Time on Page, and — if you’re running a store — improved sales.

Because Google uses site speed in its ranking algorithm, it also has a direct influence on your SEO. Fast load times can result in higher rankings and ultimately lead to increased organic traffic.

Jetpack’s new site accelerator can improve your site speed and help you take control of your SEO. This new feature, similar to our Image CDN, allows you to host static site assets — such as JavaScript files and CSS stylesheets — on Jetpack’s servers and serve them from our own Content Delivery Network (CDN). This means less stress on your servers and an improved browsing experience for your visitors.

Currently, only files included in WordPress core and the Jetpack plugin can be served by our CDN.

Ready to take your new site accelerator for a spin?

Go to Jetpack Settings Writing in the dashboard of your WordPress site and toggle the Enable site accelerator option found in the Performance & speed section. No additional configuration or set up is necessary.

We’d love to hear from you

  1. The service is useful. But the real problem is that what is stored in it, cannot be updated. You need to request a purge all the times. This makes things very complicated.

    I like Jetpack for the amazing features it offers. Just a query about the new (static) CDN feature. If the static files (CSS, JS etc.) are served from your server instead of a site’s origin server, will it have any negative impact on Google AdSense ad codes? Thanks.

      Our CDN only works for static files in WP core, Jetpack, and WooCommerce (at least for right now), so it should not affect AdSense code in any way.

    I am using JetPack from last 2 to 3 years on my website. But now I am not able to use the Jetpack plugin. When I activate the plugin, I see a 503 service error.

    I have tried deactivating the plugin and then activating it again, I have tried by deleting the existing installation of the plugin and then installing it again. I have tried by disabling all the plugins and only activated the JetPack plugin. I also have tried by changing the existing theme and used Twenty Twelve theme.

    But every time, whenever I activate the JetPack I see 503 service error.

    I have tried contacting my hosting provider which is A2Hosting, they guided me to do the same steps which I have mentioned above, but no luck.

    Kindly help me what should I do. I sent an email as well to JetPack support team from the support page but got no reply.

    My website is

    Kindly guide me what can I do… Moreover, I have also checked the SSL certificate as described on this page: and the test was clear with ‘A’ rating without any errors.

      I found your email in our support system. We did reply to you on November 5th. Did you not get that response? Try searching your email for the phrase “The first thing to try”. You might also look to see if our message wound up in your spam folder or something by mistake.

      Once you find it, please reply to us there. We can’t really provide effective support in the comments on this blog.

        Thank you, Adam, for your response. Yes, I’ve checked the email again, and I found the response in the SPAM folder.
        I have replied there.
        Hope I will get some solution.
