How do you identify the top 10 reasons customers choose your product?

It’s crucial to analyze and interview your product’s audience. For products just starting out, I conduct competitor analysis, including a review of customer feedback—both positive and negative. I then categorize these to identify the key factors influencing product choice and usage. If you already have an initial customer base (30-50 clients), it’s essential to conduct a survey. This will clearly identify the reasons customers chose your product, giving you a list of key factors to leverage in your marketing and product development. This approach ensures you’re not relying on personal impressions but on actual customer needs and values. What approaches do you use?
