Define one customer group and one problem. Interview potential customers or examine credible evidence of demand. Write a simple offer.
Create the smallest useful version. Draft a clear page describing what it does, for whom, and what it costs.
Ask a small group to try it. Watch where they get stuck. Improve the most confusing part first.
Publish the offer, share it in relevant communities where allowed, track visits and conversions, and review feedback before expanding.
Measure real demand; do not assume early revenue.
