Hey there,
Don’t feel bad for users filling our their details. Try to make it super easy and super straightforward as to why you want their details. If possible, offer them an incentive; Maybe a 5% discount coupon or priority assistance, up to you, it could be anything.
Don’t underestimate the power of customer feedback! Just give them a reason to give it to you.
As for your questions:
​
>What questions should I be asking?
Ask questions that tell you what problems the users are facing. This will help you to be the solution of their problems. Their “problems” could be high prices, low quality wear, bad customer service, expensive shipping, etc. Then build on that feedback.
​
>How long should this campaign be?
There’s no direct answer to this question but let it run until you find the answer to your last question in the list.
​
>How many metrics should we use?
While not written in stone, helpful metrics could be: impressions, clicks, conversions (form fills), bounce rate. This depends on what actions are important to your business.

>When will know if it’s a good idea or not?
After you gather enough data/feedback from the users, compare that to what your initial goal was. Do they align? Are you seeing a different reality? Will it make sense to shift towards what the data says? Does it confirm that there’s a market for your niche?
These questions will guide you towards answering your doubts about the product.
I’m hoping the best for your idea take off!
