Every product page got the return policy near the add-to-cart area to ease purchase doubts. The change lowered sales, and testing showed the cost.
Return Policy Information on Product Pages Cuts Conversion Rate 6.0%


If we add a visible return policy to product pages, then conversion rate will increase because clear return information lowers purchase anxiety and builds trust.
What We Changed
- Added the return policy to every product page.
- Placed it near the add-to-cart section or in the product details area.

Key Learnings
- Conversion rate fell 6.0% and revenue per visitor 6.9%, with an 82.1% probability that the original performs better.
- Add-to-cart rate held steady (+0.8%), so the drop came after shoppers added items.
- Conversion rate fell on both devices: 7.1% on mobile and 4.6% on desktop.
- The test ran 19 days without reaching significance, so the exact size of the drop is uncertain.
