Why we ask four questions first
The right channel depends on constraints a homepage cannot show: who you need to reach, what must improve this month, what you can spend, and who already listens to you. Those four answers are binding. A founder with no audience and no budget never gets a paid-acquisition plan or a post-more-content plan, because neither can work in 30 days from that position.
The same website with different answers gets a different plan. That is the point.
