Landing Page: Star Ratings
Test Results
Key Learning
Problem: Users on the landing page need validation from others before committing — without visible proof of success, they hesitate.
What worked: The variant addressed this conversion friction directly. (+2.2% lift)
Takeaway: Even small lifts compound — across thousands of sessions, this adds up. Now test the placement of this social proof — positioning near CTAs, in pricing sections, and in checkout flows often amplifies the effect.
How to Apply This to Your Site
This experiment demonstrated that landing page: star ratings can produce a +2.2% improvement in conversions. The test was run on a landing page page in the energy & utilities industry. With 71,171 visitors in the sample, this is a robust result.
Before you test: Consider that social proof tests typically require large sample sizes to detect small effects. This test ran for 40 days — plan for at least that long.
This result reached 95% statistical confidence, meaning there is a very low probability the observed effect was due to chance. Results at this confidence level are generally considered reliable for making business decisions.
