What can fix slow speed after coding changes in a Shopify store?

Hi, 

I have the brooklyn theme and have changed quite a bit of coding by myself to change the aesthetic and in doing so with my trial and error, I think this has affected the speed of my store.

I have tried uninstalling unused apps and installing an app that improves speed 'page speed optimizer' but I think my issues stem a lot deeper within my coding... can anyone suggest any fixes to this? 

My website is: https://stellamoon.co/

Thanks in advance,

Monique

Hi Monique,

Sorry for any formatting issues or typos. Replying on mobile.

When it comes to improving page speed, uninstalling unused apps is a great start. However, there’s some other things you’ll want to implement and look out for.

  • Uninstalling apps can potentially leave behind old app code. You’ll want to make sure all code remnants of uninstalled apps are removed from your theme’s code.
  • You’ll want to apply lazy loading throughout your theme so that all images aren’t being loaded at once. This way your theme only loads images when they come into view.
  • Compress all available images in your theme. You’ll also want to convert images from PNG to JPG format. This will reduce file sizes.
  • Minify any large JavaScript and stylesheet files. This will allow them to execute faster.

There’s some more granular optimizations you can do, but the things I mentioned above will likely provide some of the greatest improvements.
