Hey Guys,

Haven’t posted much but wanted to share this A/B splittest I’ve been running.

By reducing the load time on a email submit landing page my ROI went from 3% to just over 100%. Removed excess css and minimized javascript reduced image size by 75%. Ran an A/B splittest over 5 days. Every day was the same 3-10% verses 67-115%.

All images and JS was on my server on the winning landing page. The other landing page was using S3 to host images and javascript. Don’t think that was the factor ...
