Avoid using CAPTCHA puzzles

CAPTCHA puzzles nearly always add friction and a level of frustration to the conversion process. Unless SPAM is such a problem that it is completely unmanageable, you should avoid using them. They certainly aren’t helping your conversion rates. If you must implement a CAPTCHA, take the time to choose the right one. Some CAPTCHA technologies have improved greatly in recent years, but others can be outright impossible to solve. Don’t build such a roadblock that you block qualified leads from completing your form.
