A landing page MVP tests the most fundamental question: Do people want this enough to take action?
The experiment:
1. Build a landing page describing your product
2. Drive traffic to it
3. Measure: Do people sign up / pre-order / join the waitlist?
Cost: $0-50
Time: 2-4 hours
What you learn: Whether anyone cares
If nobody signs up for the landing page,
nobody would have signed up for the product either.
You just saved yourself months of building the wrong thing.
