The app automatically speeds up your store's load times by adding one simple script tag to your theme called booster-page-speed-optimizer.js.

Page Speed Optimizer is made and designed to help boost the speed of your site in terms of clicks by pre-loading links. Unfortunately, it has no bearing on your site ranking when it comes to SEO.

If you're looking to improve your site's SEO rankings, check out our SEO Optimizer app!

Amazon and others found out that cutting 100 milliseconds of latency improves sales by 1%. This app will help improve your conversions.

Nope — this app is and will always be 100% FREE!

Upon installing the app, it will ask permission to access and modify store data. This is necessary to install and run the app and its files in your theme.

Simply click the Enable Theme Extension button, enable the app on the theme section, and then click Save. No need to do anything else, the app will do its thing!

Page speed applications such as Pingdom or GTmetrix will not show any improvements when Page Speed Optimizer is installed. These apps measure page speed on the first page when it is the first time opening the site while Page Speed Optimizer only starts working after the first page load as we are preloading links on the page.

You can sync the app to your store to make sure all settings are applied.

You can uninstall the app by clicking Delete beside it on your Shopify admin page.

You can also remove this line from your layout/theme.liquid file:

​{{ '//cdn.shopify.com/s/files/1/0194/1736/6592/t/1/assets/booster-page-speed-optimizer.js?23' | script_tag }}

Simply disable the app from the theme section and click Save.
