Speed optimization for your Shopify store is essential. Users shouldn't wait long before the store loads. You will lose potential customers if they leave before your website loads. Also, Google doesn't like slow sites and downgrades their rank. Speed optimization, though, can be a costly process, so you should find a balance between cost and profits. Below are the primary things you can do to get the most significant upgrade on your website.

The first thing to consider is your site's measurements. The two primary metrics are the Google PageSpeed Insights tool's rating and the real load speed, which you can measure with GTmetrix.

After the last update, it uses Google Lighthouse, and now it is more informative and powerful. At the same time, it has become more demanding for mobile versions.

Shopify Website Optimization Approach

Let's try to do less and receive more. If you run Google PageSpeed Insights Tool and GTmetrix, you will get a lot of recommendations. However, don't try to do them all.  For example, they offer to eliminate render-blocking resources. It means that you should move all CSS and JS to the bottom of the page. Page layout breaks during loading and JS could crash if you do that. It will take a lot of time to fix, so it is not the suggested way. But what should you do first?
