Depending on your problem, you might need different types of data and different ways of collecting them. For example, primary research involves gathering data directly from your target market, while secondary research involves using existing data from other sources. Qualitative research explores the attitudes, opinions, and motivations of your target customers, while quantitative research measures the size, behavior, and preferences of your target market. You could use surveys, interviews, or focus groups to get feedback from potential customers. Additionally, online tools such as Google Trends, Keyword Planner or SimilarWeb can analyze the online behavior and demand of your target market. You could also use industry reports, publications, or databases to get insights into the trends, opportunities, and challenges of your market. Furthermore, SWOT analysis, Porter's five forces or value proposition canvas can help evaluate your strengths, weaknesses, opportunities and threats in relation to your competitors.
