What remains to be verified?
The following are research questions, not established market opportunities.
- What do target users actually pay for? Is there direct user feedback or paid interview evidence?
- Are these historical prices still active today? What are the conversion, retention, and fulfillment costs?
- Is the "SEO" channel still viable? What resources do indie devs need to test it?
- Whose needs are competitors failing to meet? Find specific evidence before deciding on your angle.
