Image optimization is a no-brainer for conversion rate improvement but often gets overlooked in favor of other shiny optimizations. Are you still using <10kb images? You should be if they're not critical to your page load speed. But what about that hero image on the homepage?
Here's my trick: Use
? srcset=pic. jpg 84w, pic@2x. png 376w
for retina displays and smaller screens. Save up to 50% in bandwidth, w/o sacrificing quality or user experience.
