Test #435 on Volders.de by Daria Kurchinskaia   Oct 17, 2022 Desktop Mobile Checkout

Daria Kurchinskaia Tested Pattern #9: Multiple Steps In Test #435 On Volders.de

In this experiment, a question about a customer's reason for purchase was broken out into a separate step and moved earlier in the process. In the control, this question was asked in the final checkout step along with a plan selection (Step 4 of 4). In the variation, this question was shifted as a standalone first step (Step 1 of 5). Impact on completed purchases was measured (for a contract cancellation service in this case).

Test #427 on Designlab.com by Daniel Shapiro   Aug 10, 2022 Desktop Mobile Checkout

Daniel Shapiro Tested Pattern #28: Easiest Fields First In Test #427 On Designlab.com

In this experiment, the course enrollment start date was moved from step 2 to step 1 of an enrollment / checkout flow. The test was run by Designlab - that offers design courses and education with a strong element of mentorship. Impact on progression to next step and completed transactions were measured.

Test #415 on Learnwithhomer.com by Stanley Zuo   Jun 09, 2022 Mobile Checkout

Stanley Zuo Tested Pattern #3: Fewer Form Fields In Test #415 On Learnwithhomer.com

Do fewer confirmation form fields matter? In this experiment, redundant password and email confirmation fields were removed during a signup / checkout funnel. Impact on signups was measured.

Test #414 on Volders.de by Frederik Fröhle   May 31, 2022 Desktop Mobile Checkout

Frederik Fröhle Tested Pattern #98: Auto Suggest In Test #414 On Volders.de

Does adding Google's address auto complete functionality to an address field help with higher form completions? This auto fill feature has been tested in the variation of a contract cancellation funnel. After selecting an auto completed address from a pulldown menu, the following fields were preselected: house number, zip code, city and country (potentially lowering friction?). Impact on successful form completions (contract cancellations) has been measured. Notice how the form also expanded progressively upon selecting the complete address in the variation.  

Test #412 on Volders.de by Frederik Fröhle   May 16, 2022 Desktop Mobile Checkout

Frederik Fröhle Tested Pattern #15: Bulleted Reassurances In Test #412 On Volders.de

The Volders experimentation team assumed that adding information about how long it might take to get a cancellation confirmation near a CTA Button would result in higher cancellation requests (the paid service being offered).

The variation contained additional copy translated from German to: "Most of our users receive their cancellation confirmation from <vendor> within 14 days by email or letter."

Jakub Linowski Tested Pattern #35: Floating Labels In Test #399

In this experiment, top-aligned field labels were tested against floating labels (with labels floating inside the form field itself).

Test #390 on Snocks.com by Melina Hess   Dec 21, 2021 Desktop Mobile Checkout

Melina Hess Tested Pattern #106: Back Buttons In Test #390 On Snocks.com

In this experiment, the variation has a "Back To Shopping Cart" link right underneath the checkout button. Impact on sales was measured.

Test #389 on Svsound.com by Keenan Davis   Dec 16, 2021 Desktop Mobile Checkout

Keenan Davis Tested Pattern #1: Remove Coupon Fields In Test #389 On Svsound.com

In this simple experiment, a highly visible coupon field was replaced with a less visible (but clickable) link in the variation. Clicking on the link would show the coupon field. Impact on sales and revenue was measured.

Someone Tested Pattern #9: Multiple Steps In Test #61

In this experiment, a single screen checkout was turned into a series of smaller steps in variation B. This was achieved by showing fewer fields on the first step, and shifting the remaining ones into a 3 step modal popup. The experiment measured successful transactions (sales).

Online Dialogue Tested Pattern #111: Field Explanations In Test #261 On Valkexclusief.nl

In this experiment on Valk Exclusief's web site, a reason was provided for why the e-mail address is being collected. Google translation of the added text is as follows: "If your e-mail address is not yet known to us, we will ask you to add some missing information. Then you immediately benefit from our benefits such as the ValkLoyal savings program."
