Asking your users to give you feedback on something you built can be tricky.
One simple and effective way to do it is to jump on a call with them, ask them to use it and observe them.
Here is what you should keep in mind:
Ask your users to complete small focused tasks.
For example: You are building a platform where people can sell products. Ask them to "add a new product".
This is by far one of the simplest and most effective methods to get insights. It's like getting access into your users' brains.
Your goal is not to sell your product or to prove that you are right.
Your goal is to understand how they feel when using it.
Practice your listening skills. It's tough at first but gets better as you practice.
The best results come from testing no more than 5 users and running as many small tests as you can afford.
Actually even just 2 or 3 will give you plenty of insights!
