New Optimization App: The Shopify Analyzer

2019-03-05T11:28:26-04:00March 5th, 2019|Performance Optimization, Tools|

We built an analysis tool for Shopify sites, the Shopify Analyzer!

It’s a free web app to analyze any page on your site and give optimization opportunities and recommendations to make your Shopify site faster.


The goal is to provide a tool for you to quickly check the performance status on any page of your site, and have actionable information to fix it.

This app will also help us keep site analysis free for you – we use the same app to analyze your site.


Speed Boostr has been in action since 2017 – we’ve used just about every performance tool out there and analyzed a LOT of sites.


Case Study: Google PSI Score Is Not Equal to Page Load Speed

PageSpeed Insights (PSI) is a web performance analysis tool developed by Google to help you optimize your website.

It’s a useful tool to find optimization opportunities. It’s one of the analyzers we use in our toolbox.

It’s not a useful scoring system for Shopify sites or complex platforms that integrate with 3rd party apps.

Why we don’t use it as a benchmark/scoring system:

  • Sometimes you implement an optimization that clearly makes your site faster, but then the score goes down 🧐
  • Sometimes you clear warnings they give, and the score goes down
  • Sometimes when comparing 2 sites, the faster site scores lower

Finding and Fixing Server and JavaScript Errors

Over the course of website customizations and installing / uninstalling 3rd party apps, you can introduce code misconfigurations and server errors.

If you’re on Shopify, these are often caused by old or broken app code.

When you uninstall an app from Shopify, it doesn’t always remove ALL the app code from your theme – we regularly find old app code still loading on the sites we optimize.

You can find these errors using the Chrome Dev Tools console, it looks like this: (more…)
