Where do users come from?
4,522 visits in September, 100% US. Search 51.7%, direct 31.1%, referrals 10.3%; search queries are mostly brand and book-title terms (the product design playbook by consumer app, bartek marzec), so new users are people who saw the author's content and then searched; social source is Facebook.
Channel share, initial acquisition, and growth drivers are distinct; correlation does not imply proven causation.
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 "Other" 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.
