I have put my website through Google's Lighthouse extension and the lastest result is 21 for MOBILE and 75 for DESKTOP.

Major recommendation says to:

  • Defer offscreen images
  • Minimize main-thread work
  • Ensure text remains visible during webfont load
  • Avoid enormous network payloads.

     I'm no expert. just try to read many articles and fix by trial error. I've tried to compress my css files- but honestly am not sure how to. I've also tried to do Lazy Load, IntersectionObserver some lower pictures on my site but again...can't figure it out. It seems not working for MOBILE. Any suggestions or links to specific (dumbed down) articles? and I am using Narrative customized theme. I plan to move to Debut customized.

Thank you in advance,
