Optimize online store

Topic summary

A Shopify store owner seeks help improving their site’s mobile and desktop performance. The store URL is lojamanuelcoelho.com.

Initial guidance provided:

  • Test performance using Google PageSpeed tool
  • Optimize and convert images to .webp format
  • Remove unused CSS/JS code
  • Fix render-blocking resources
  • Implement lazy loading for media
  • Address JavaScript errors
  • Optimize CSS/JS files

Current challenges:

  • Store owner struggles with implementation, repeatedly asking where to paste code snippets
  • Reports no improvement after attempting fixes
  • Cumulative Layout Shift (CLS) remains at 0.12
  • Performance appears worse than previous day based on shared screenshot
  • Requests direct assistance with technical implementation

The discussion remains unresolved with the owner needing hands-on help rather than general guidance. Multiple offers of paid services were mentioned but details about trial periods and specific implementation remain unclear.
