Checkout: Add More For Extra Incentive
Hypothesis
If we implement 'Add More For Extra Incentive' on checkout pages (In this experiment, two changes were made to the checkout page: (1) the minimum basket size requirement was made more visible using a floating element, and (2) an additional thresh), then key conversion metrics will improve.
Test Results
Key Learning
Context: Key actions on the checkout disappear as users scroll, creating a gap between intent and the ability to act.
What was tested: REAL-WORLD TEST: 'Add More For Extra Incentive' was tested on a live checkout page. The test involved 36,284 real visitors. Full statistical results require paid access. Test methodology: In this experiment, two changes were made to the checkout page: (1) the minimum basket size requirement was made more visible using a floating element...
Result: No statistically significant difference was detected. This null result is still valuable — it narrows the search space and helps calibrate your minimum detectable effect for future tests.
How to Apply This to Your Site
This experiment tested checkout: add more for extra incentive but produced no statistically significant change. The test was run on a checkout page in the cross-industry industry. Inconclusive results suggest this particular change may not be a priority — focus testing effort on higher-impact areas.
Before you test: Consider that form tests typically require large sample sizes to detect small effects. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
What Was Tested
In this experiment, two changes were made to the checkout page: (1) the minimum basket size requirement was made more visible using a floating element, and (2) an additional threshold was introduced to encourage customers to add more items by offering a free gift at a higher spend level. The impact on sales was measured.

Problem: Coupon and promo code fields on checkouts can distract users — they leave to hunt for codes, reducing completion rates.

Checkout: Fewer Form Fields
Context: Each additional form field adds friction to the checkout, increasing the chance users abandon before completing their submission.
