Best Customer Research Questions

Finding the Right Message by Jennifer Havice describes 6 killer questions to gain information on how to improve your sales/landing page copy.

I personally find these questions not just useful to improve my website copy but also especially useful in the early stage of a startup/side project after you gained your first customers. You can then narrow down on what your customer actually wants (problem fix), gain insights how to improve your product (concerns/hesitations), and do proper competitor research (alternatives) and more.
