Homepage: Social Proof Header (600K Facebook Fans)
Hypothesis
Replacing a rotating testimonial banner with a static social proof stat showing large Facebook following would build trust faster with new visitors
Test Results
Key Learning
Problem: Users on the homepage need validation from others before committing — without visible proof of success, they hesitate.
What worked: Large, specific social proof numbers in a static header beat rotating testimonials. For brands with strong social followings, leading with that credibility signal near the top of the page converts better than product-focused messaging. (+44.0% lift)
Takeaway: This is a significant win worth prioritizing for implementation. Now test the placement of this social proof — positioning near CTAs, in pricing sections, and in checkout flows often amplifies the effect.
