Checkout: Single Or Double Column Form Fields
Hypothesis
If we implement 'Single Or Double Column Form Fields' on checkout pages (In this simple [inverted] experiment, the variation organized the form fields into a single column), then key conversion metrics will improve.
Test Results
Key Learning
Context: Each additional form field adds friction to the checkout, increasing the chance users abandon before completing their submission.
What was tested: REAL-WORLD TEST: 'Single Or Double Column Form Fields' was tested on a live checkout page. The test involved 2,143 real visitors. Full statistical results require paid access. Test methodology: In this simple [inverted] experiment, the variation organized the form fields into a single column. The control had two columns of form fields.
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: single or double column form fields 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 adequate traffic to reach statistical significance. Run your test for at least 2 full business cycles to account for weekly traffic patterns.

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