Homepage: Screenshot Testimonials (Non-Authentic) Hurt Signups -9.7%
Hypothesis
Adding Twitter screenshot-style testimonials will add social proof and increase signups
Test Results
Key Learning
Problem: Users on the homepage need validation from others before committing — without visible proof of success, they hesitate.
What was tried: Inauthentic-looking testimonials may actively reduce credibility by triggering skepticism. Embed real review widgets from G2/Trustpilot/Capterra with verified badges instead of custom screenshot-style cards. Authenticity signals matter as much as the content. (-9.0% change)
Why it failed: Social proof isn't universally positive — the wrong type, amount, or placement can feel manipulative or irrelevant.
How to Apply This to Your Site
