Upsell and Cross-Sell Modal Shows a 9.7% Conversion Rate Lift


If we suggest a higher-priced alternative or a complementary product in a modal, then average order value will increase because some shoppers will trade up or add another item.
What We Changed
- Added a modal suggesting a higher-priced alternative to the item a shopper picked.
- Offered complementary products in the same modal as an add-on.

Key Learnings
- Conversion rate rose 9.7% and orders 9.9%. No significance figure was available, so this is a signal worth acting on, not proof.
- Revenue per visitor rose 12.6%, mostly because more shoppers ordered.
- Average order value, the metric the test was set up to move, rose only 2.6%.
- Nearly all 18,583 visitors were on desktop, so the result says little about mobile.
