A/B Test: Which Webinar Time Increased the Registration Rate 91.13%?


As our resident A/B Test Analyst, I might be biased. But I truly believe that A/B testing is a very versatile tool that many people do not use to its full potential. Most people see A/B testing just as an opportunity to test page elements such as call-to-action buttons, images, and copy.

However, A/B testing can be used for so much more. It can also help you test different aspects of your business strategy, product, or service to find out what your visitors prefer the most.

In this A/B test, webinar host Doren Aldana decided to use LeadPages’ split-testing tool to test two different webinar times for his West Coast audience. Version A promotes a webinar at 11 PM PST, while the webinar for Version B takes place at 11 AM PST.

If you chose Version B you are correct!

Version B, with a 100% probability of outperforming Version A, increased opt-ins by 91.13%.

Although we can’t say with total certainty why this change caused the increase, it may be safe to say that Mr. Aldana’s visitors in the Pacific Time Zone prefer their webinar to start at 11 AM, rather than 11 PM. Thanks to split testing, he was able to get real time feedback from his visitors by using A/B testing in order to improve his business strategy.

How cool is that?

Now, eagle-eyed readers may notice a slight headline change as well: where one version has “supercharge,” the other has “turbocharge.” It seems somewhat unlikely to me that this had a large impact on the outcome . . . but as a responsible A/B Test Analyst, I’m compelled to point it out.

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

Not all visitors are the same, but A/B testing your business (such as webinar times) via your LeadPages® may be something to consider for your business.

    I wouldn’t take anyone in business seriously if they suggested an 11pm start time. Plus, that would be 2AM on the East Coast…so I’d assume it was an error.

    • Daphne Sidor

      Both good points, Delane. I think in general, if you’re going to make such a big departure from convention in your marketing, you’ll need to call it out and make your reasons clear to your audience—otherwise, it’s likely to look like a mistake or like you’re a little out of touch.

  • Neither – there’s no “in your time zone”! (for Aussies, this is a constant grind)

    • Daphne Sidor

      Ha, good point, Keely! Webinar timing is also interesting because you ultimately want to track not just the opt-in rate but the show-up rate, and oddly enough, sometimes the time that prompts the most people to sign up doesn’t get a great attendance rate, or vice versa. Lots of factors to juggle.
