tips for building a good customer feedback form

were launching a customer feedback form and want to do it right. based on my past experience with bad surveys that nobody completes, im thinking: - keep it short (5 questions max) - mix of rating scales and open-ended questions - conditional follow-up: if they rate low, ask what went wrong. if high, ask for a testimonial - thank you page with a CTA to leave a public review anyone have tips on what works well? what questions actually get useful responses vs just checkbox fatigue? also planning to trigger different workflows based on the score - low scores go to our support team immediately, high scores get a review request email a week later
