Captchas Aren’t Captivating.

Captchas — those little boxes with hard-to-read words or combinations of letters you encounter online — are there to make sure you’re a real human.  What they actually do is make sure you’re frustrated, especially if you’re on a mobile device, as more and more online traffic is.  In fact, it’s fair to say that captchas, far from helping capture business, often repel it.  So unless you have an incredibly good reason to incorporate them, don’t.
