A short, focused PDF (10-25 pages) that solves one exact problem with one specific tool or method — no theory, no filler, just a step-by-step walkthrough that replaces hours of searching and experimenting with a clear, tested process the buyer can follow in one sitting.
Skip a generic micro guide — search demand is roughly 50/mo and declining, and the visible comps ($1-$20) show no evidence of real sales volume, so this reads as a format, not a market.

A short, hyper-focused PDF (10-25 pages) that solves exactly one problem using exactly one tool or method. Not an ebook, not a course, not an overview. A micro guide that a buyer opens, follows step-by-step, and finishes with a working result in under an hour. The format works especially well for fast-moving tools like AI products, developer workflows, or business software where official docs are confusing and YouTube tutorials are outdated by next month. If the guide replaces 3+ hours of Googling and experimenting, the $9-$25 price feels like a bargain.
