Profitable niches usually leave clues before they become obvious: repeat searches, underserved subtopics, proven buyer behavior, and manageable competition.
Do not start by making the brand, the cover, or the channel art. Start by checking whether people are already signaling interest through searches, purchases, and repeat conversations.
A rough but validated idea beats a polished guess.
If a topic looks crowded, add one filter: audience, format, goal, season, tone, or outcome. That is often enough to move from saturated to testable.
For example, journaling becomes pregnancy journaling, meal prep becomes budget meal prep, and woodworking becomes woodworking for apartment spaces.
Search multiple sub-niches and use the scores to decide which angle deserves real effort.
