What approaches to studying your target audience do you prefer?

I used the following methods in my work: Surveys and Questionnaires: They can help gather initial feedback about a product idea, understand market needs, or test potential product names or features. Interviews: Start by speaking directly with friends, family, or acquaintances who might be part of your target market. It helps in understanding deep-seated needs, pain points, and desires of potential users. Competitive Analysis: Researching competitors or related products can offer insights into what's working in the market. Look at product reviews, customer testimonials, and Q&A sections. Ideal Customer Profile: Creating detailed customer personas helps you visualize and understand your potential users' needs, challenges, and behaviors. It's based on a mix of educated guesses and any market research data you can gather. What is your favorite method and why? By the way, we recently launched our product, which allows you to create detailed Ideal Customer Profiles. Check it out >> https://www.producthunt.com/post...
