The next question is how to choose the right product categories for your e-commerce site. There is no one-size-fits-all solution, but there are some general principles and best practices you can follow. First, you need to understand your target audience, their needs, preferences, and behavior. You can use tools like surveys, analytics, and customer feedback to gain insights into your customer segments and personas. Second, you need to analyze your product portfolio, its features, benefits, and differentiation. You can use tools like product attribute mapping, keyword research, and competitor analysis to identify the most relevant and distinctive aspects of your products. Third, you need to create a hierarchical structure of categories and subcategories, based on the commonality and specificity of your products. You can use tools like card sorting, tree testing, and prototyping to test and refine your category structure and labels.
