A/B Test: Which Progress Bar Increased Opt-Ins by 19.05%?

The law of inertia says that a body at rest stays at rest, and a body in motion stays in motion, unless acted on by an external force. Marketers have borrowed this scientific truth and turned it into a concept known as “behavioral inertia.” That is, once your visitors have started moving in one direction—toward your email list—they’re likely to continue down that path unless something interrupts them.

That’s the theory behind including progress bars on your opt-in forms: if you can remind people that they’re already part way done, they’ll be more likely to finish opting in. In this A/B test, Marc Luber from JDCareersOutThere.com decided to see whether adding some extra motion would give visitors an extra push.

Did adding animation keep users in motion? Or were they more likely to opt in without the potentially distracting action?

Which version do you think increased opt-ins for this LeadBox™ by 19.05%?

If you chose Version A you are correct!

Version A, with a 100% probability of outperforming Version B, increased opt-ins by 19.05%.

Although we can’t say with total certainty why this change caused the increase, here are a few of my speculations:

  1. The motion of the animation grabbed the customer’s attention and clearly communicated that they were close to getting what the call to action promised.
  1. Version B places the “50% Complete” text inside the progress bar, which may make it less legible and less compelling.

Why do you think Version A outperformed Version B? Let us know in the comments!

Not all visitors are the same, but A/B testing your progress bars may be something to consider for your own LeadBoxes®.
