Your best bet is a personality quiz
Based on your answers, you should build a personality quiz. Think:
- How their preferences align to something deeper in their personality
- What sort of career path they should take
- What their signature color is
These types of quizzes can get misaligned pretty quickly, so make sure you don't veer too far into the "fun but not at all related to the problems my business solves" territory. As in, unless you sell salsa, "which nacho topping would you be?" is irrelevant. Fun, but won't help you build your business.
What will help you grow your business, however, is The Quizillionaire Toolkit. It's a DIY course that will help you get your quiz built, launched, and collecting email addresses in as little time as possible.
