Hey there, @lawrencelv
Bo here from Shopify Support!
It is great to see you be so proactive about your site's performance. While the speed test tool is super insightful, it’s easy to take Google’s PageSpeed Insights advice on your Shopify theme a bit too much to heart while also ignoring some easier ways to improve your site performance. For both desktop and mobile, it's important to keep in mind that the score Google gives you is just one factor that determines how your site is ranking and how well it performs for users and in search rankings. While it's always a good idea to what you can to improve your site speed, chasing after a 100 is not a good use of your time as a business owner. Keep in mind that most, if not all, of the elements that page testing tools flag are necessary to make it possible for your customers to browse and buy on your site.
With that said, there are plenty of ways that you can improve your site speed without needing advanced development.
All the Best,
