Someone bounces off your Amazon author page. They wanted paperback, but you only offer Kindle.
There are thousands of other books. Many come in the format they actually want.
So you make the paperback. Then the hardcover. Then the audiobook. Same book, different doors.
The commuter finds the audio version. The person who gifts books finds the hardcover. Each format catches different people.
Then you notice your other ways of expressing your message. You already have an email series, maybe a course, and a mentoring program.
But they're not connected to the book.
The book reader doesn't know about the course. The course student hasn't seen the book. The mentoring client never heard about the email series.
Same ideas, scattered across different places.
You could link them easily. Book to course, course to mentoring, email series to everything. We don't have to call it funnel marketing. We're just connecting the dots.
Your work wants to reach people. Different people learn differently. Different budgets, different time, different preferences.
Sometimes this means stepping beyond what you'd ideally choose. The introvert making videos. The writer doing live calls. The person who prefers deep work creating simple checklists.
The more ways you offer your message, the more people can find their way in. Your book doesn't have to stay just a book. It can become whatever serves the ideas best.
