I want to sell digital products but analyze: what digital products actually sell? Map digital product types: templates, courses, ebooks, software. Calculate: creation time vs. price point vs. volume needed for income. Show me the digital product hierarchy: these sell well, these don't. Give me the product strategy: create this type, price at this, need this many sales. Include: which digital products are easiest to sell, what pricing works, and whether digital products are actually passive income.
