Checkout: Fewer Form Fields
Hypothesis
If we implement 'Fewer Form Fields' on checkout pages (Do fewer confirmation form fields matter? In this experiment, redundant password and email confirmation fields were removed during a signup / checkout funnel), 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: 'Fewer Form Fields' was tested on a live checkout page. The test involved 2,286 real visitors. Full statistical results require paid access. Test methodology: Do fewer confirmation form fields matter? In this experiment, redundant password and email confirmation fields were removed during a signup / checkout...
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: fewer 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.
