GTMetrix - Minify Javascript

New Member
5 0 0

Hi guys,

Looking for some help with regards to page speed.

When running GTMetrix on my store I score an "F" for the "Minifying Javascript" however my site is pretty good for all other metrics.

Can anyone give me a step by step on how to complete this task? I've added a screenshot of the GTMetrix report. I only need to fix the top 3 to get a "A" grade.

Any help would be very welcomed

Hello, David Welcome to the Shopify Community! This is Syed Mustafa a professional Shopify Developer. As I'm sure you well know, page speed has become a factor for ranking in the search engines. That's why if you're investing lots of time and money into getting the rankings you deserve, you shouldn't be blowing it by having a slow website. Longer load times have also been shown to negatively affect conversions. “My Aim” is to optimize the website speed up to 90% on any device. It’s helpful to the visitor who visits on your website and spends much time without annoyed. I've gone through your website speed details and the reason behind why the website is slow is that there are lots of unused code of Javascript and CSS that's why your website loading speed time is more than 14 seconds and slow speed means that you are losing your potential customers and profit so it's a work that can be done by custom coding and I am professionally able to do this for you. Drop your reply at and start this project as soon as possible. Thanks and Best Regards

Looks like most of the scripts in your screenshot are from apps and other 3rd party like Facebook. You cannot optimize these scripts, that would have to done by the app developers. All you can do there is to remove as many of these apps and marketing scripts from your site as you can. In some cases you may be able to control when and where these scripts are loaded on your site. There are some strategies to this, such as deferring scripts and lazy loading them some time after the initial page load or on some event like scroll or click.
