We’ve had the best success for our clients by working with our developers to implement the lazy sizes because it's quite complicated for non-technical people.

You need to work on the following points:

  • Theme Upgrade if there is a scope and upgraded theme available
  • Reduce JS Payload.
  • Use Critical CSS.
  • Replace GIFs With Static Images
  • Reduce Large Image Sizes
  • Migrate Tracking Codes To Google Tag Manager
  • Compress Images
  • Limit Third-Party JavaScript & Shopify Apps
  • Preload Web Fonts. 
  • I suggest limiting it to one and using a standard web font.


Theme Upgrade:

Its benefits include improved loading speeds, which can help with both user experience and store conversion rates, and search engine optimization.

By fixing these issues, your website speed score can definitely improve.
