How Many Fields Should Your Opt-In Form Have? This A/B Test Could Help You Decide

Just because you can add half a dozen form fields to your LeadBoxes® doesn’t mean you should. Most marketers find that a more minimalistic approach to collecting leads’ data gets better results, but how low should you go?

That’s likely to depend on the type of business you run and your visitors’ motivations. To find out what would work for his agency, Matt Thomson from Connect Social Media ran an A/B test on one of his key LeadBoxes®.

Would using a single form field reduce friction and give Matt more opt-ins? Or would a two-field strategy increase the perceived credibility of the video series, as well as the opt-in rate?

Which version do you think increased this LeadBox™’s opt-ins by 12.44%?

If you chose Version B you are correct!
Version B, with a 100% probability of outperforming Version A, increased opt-ins by 12.44%.
Although we can’t say with 100% certainty why this change caused the increase, here are a few of my speculations:

  1. Removing the “first name” form field from Version B reduces the visual clutter within the LeadBox™.
  2. It’s simply easier for visitors to opt in when less information is required.

While fewer form fields are better for conversion in many cases, keep in mind that your own audience may vary. (For instance, offering a custom lead magnet may require you to collect more info—more on that in this guest post.)

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