Most marketers talk about their process or features. But this Copywriting Course testimonial skips that and jumps straight to the results: 0.2% to 5.2% conversion lift. That’s what prospects actually care about.
Why it works
Numbers give proof that can’t be argued with
“Before and After” makes results instantly clear
Real quotes add credibility and trust
Visual contrast (red vs green) makes the win pop
