Signup: Forced Action
Hypothesis
If we remove the option to skip or close a signup step, then signups will improve because focused funnels without escape options increase step completion.
Test Results
Key Learning
Problem: The primary call-to-action on the signup isn't converting at its potential — design, copy, or placement may be the bottleneck.
What worked: Removing skip/close options from signup steps improves step completion. Validated across 4 related tests show this improves signups (+12.5% lift)
Takeaway: A meaningful improvement that compounds with other optimizations. Use this win as a foundation for further iteration on adjacent elements.
How to Apply This to Your Site
This experiment demonstrated that signup: forced action can produce a +12.5% improvement in conversions. The test was run on a signup page in the e-commerce industry. With 36,898 visitors in the sample, this is a robust result.
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.
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
In this experiment, the control shows an (X) close option within a signup flow, whereas the variation had it removed. Clicking the close icon would collapse the signup modal and show the product page. Users were still able use the back and forward functionality. (The test was inversed in order to fit the pattern). Impact on signups was measured.

Problem: Visual elements on the listing aren't doing enough to communicate value, build trust, or guide users toward the next step.
Checkout: Remove Coupon Fields
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.
