Think for a second about the last time you needed to create a form on your site. Whether it was for a shopping cart or lead generation, it probably had a field where you asked the customer to select one of multiple options. Perhaps the field was:
• Credit card type
• Subscription length option
• Company revenue range
• “Yes” or “no” to newsletter opt-in
Whatever it was, you probably didn’t think too hard about whether you should use a dropdown or a radio button to let your visitor select their option. Most of us decide quickly as we’re creating the form in our CMS or form software.
But what if choosing the right format, radio buttons or dropdowns, for a single question in your form meant seeing a performance differential of 15%?
In this Web clinic, we’ll walk you through an experiment where that was exactly the case. Getting the question format right generated a 15% lift in total orders.

4. Experiment: Background
Experiment ID: TP1774
Record Location: MECLABS Research Library
Research Partner: [Protected]
Background: A large people search company catering to customers searching for
military personnel.
Goal: To significantly increase the total number of subscriptions.
Research Question: Which subscription option format will produce the highest
subscription rate: a dropdown or radio button?
Test Design: A/B single factorial split test
8. Experiment: Results
15% Relative increase in orders
In this case, the radio button field outperformed the dropdown field by 15% in order rate.

Key Principles
1. One of the most effective ways to improve the performance of the webpage is to
reduce friction (psychological resistance).
11. What is friction?
Definition: Friction
Physics: A force that resists the relative motion or tendency to such motion of
two bodies in contact.
Marketing: Psychological resistance to a given element in the sales process.

Key Principles
1. One of the most effective ways to improve the performance of the webpage is to
reduce friction (psychological resistance).
2. However, in our attempts to minimize friction (length-oriented), we must beware
of undermining the conversation with the customer in 2 ways:
i.
Intensifying difficulty-oriented friction
17. Danger #1. Increasing difficulty
• By moving from a
radio to dropdown
field, we significantly
reduced the
perceived length of
the form.
Radio
Dropdown
18. Danger #1. Increasing difficulty
• However, length is only
one form of friction. By
reducing the length, we
inadvertently increased
difficulty.
• Now, instead of clearly
seeing all of the options
available to the
customer, they have to
click and squint to
examine the options.

• Version A is a 3-step cart
checkout process. The
length of the process is
significant.
• Our analysts
hypothesized that by
shortening the steps into
a one-page accordion
checkout process, we
could reduce lengthoriented friction.

What You Need to Understand: While we
may have reduced length, we increased

• By de-emphasizing the savings

the value.

Background: An addiction and mental health rehabilitation facility.

• Version A is long copy

In the end, increasing conversion is less about the technique (dropdowns vs. radio
buttons), and more about understanding the entire mental impact (value vs. cost).
