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.  

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."

In this experiment, an urgency related message with a dynamic countdown timer was added on the final checkout screen. Impact on sales was measured.

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

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

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.

In this simple [inverted] experiment, the variation organized the form fields into a single column. The control had two columns of form fields.

Three common delivery questions were answered at the bottom of a checkout page. 

In this experiment, the variation added a second total price at the bottom of the checkout screen just above the checkout button. The impact on sales was measured.

An extra "Place Order" button was duplicated above the fold on this checkout page. The control had a similar button further down at the bottom of the screen. The impact on total sales was measured from this change.

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).

In this experiment, a fully visible coupon field (A) was made less visible by turning it into a default collaped link (B). Clicking on the link caused the coupon field to appear.

A "Step X of 4" progress bar was tested against a fully visible one that was also clickable.

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."

In this experiment, the Yoast team replaced one of the bulleted reassurances on their checkout page ("4.9 out of 5 stars" vs "24/7 Free support"). Raising the question - is free support or high reviews valued more? - Thanks Sjardo & Meike for sharing!

The variation added a progress bar to one of the checkout steps for a ticket ordering site.

In this experiment, the form layout was adjusted by shifting the side benefits further down below the form.

In this experiment, testimonials were added on a checkout screen.
