Homepage: Form Field Reduction (Postpone Fields to Next Step)
Hypothesis
Removing form fields from the homepage (showing only the primary CTA) and deferring data collection to the next step will reduce friction.
Test Results
Key Learning
Problem: Each additional form field adds friction to the homepage, increasing the chance users abandon before completing their submission.
What worked: Reducing the immediate ask on the entry point (homepage) and deferring data collection reduces up-front friction. The committed users who click through are more likely to complete the full form. Small lift but high confidence. (+9.0% lift)
Takeaway: A meaningful improvement that compounds with other optimizations. Every field removed or simplified reduces friction — continue testing inline validation, progress indicators, and smart defaults.
How to Apply This to Your Site
This experiment demonstrated that homepage: form field reduction (postpone fields to next step) can produce a +9.0% improvement in conversions. The test was run on a homepage page in the cross-industry industry.
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.
This result reached 95% statistical confidence, meaning there is a very low probability the observed effect was due to chance. Results at this confidence level are generally considered reliable for making business decisions.
What Was Tested
Test #10 : 3 form fields were removed from the homepage, leaving only a 'Start Trial' button. Users who clicked saw all fields on the next step. Result: +3.9% more leads with high statistical power (5.7%).

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