Mobile Page Speed Results

Load time for site on mobile: 11 seconds (industry standard is <2-3s)

Technical issues slowing down site on mobile (numbers correspond with picture)
1) Reduce Unused Javascript
Excess Javascript code in your site is slowing it down. There are four ways that Javascript code can be injected in your site: when you plugin a Shopify app, when you use certain themes, when you use third-party scripts such as Facebook Pixel or Google Analytics, and if you have custom code on your site. The biggest culprit is Shopify apps. Even if you delete the app from your site, the code stays behind. This can be fixed by auditing the site’s code and removing all unused Javascript code.
2) Main Thread Issues
Main thread overload happens when too many tasks, like heavy JavaScript execution, complex CSS code, and third-party scripts, are processed simultaneously. This slows down the site’s load time. The best way to fix this is to delete unused Javascript, compress essential Javascript code, and remove unnecessary third party scripts.

Optimization & Expect Benefits

The best solution for these problems is a codebase audit.
The first step would be to delete any unused Javascript code on the site and reduce the size and complexity of necessary JavaScript files. Most Shopify apps and themes inject code into the site, and this code remains even if the app is removed or theme is changed. Every so often, a developer needs to go through and optimize the code for efficiency.
The second step would be to go through your HTML code and remove any extra tags or elements that don’t serve a purpose. This makes the webpage lighter and faster to load.

When properly optimized, the site’s load time on mobile would be between 2-3 seconds (down from 11 seconds) and the site’s load time on the web would be between 1-3 seconds (down from 3.9 seconds).

Research shows that every 1s decrease in a Shopify site’s load time can increase conversion rates by 20-50%.
