What book will teach me what to post?

I need book recommendations because I want to start am AI Instagram Reels or YouTube Shorts channel. However I don't want to dive in immediately and start posting things that simply align with the latest trends; instead I want to create posts that i'm confident will preform well. I know that psychology, marketing and statistics knowledge could aid my thinking when making a post but I don't know enough about those subjects to find the right book.

And if you don't know any books tell me: how did you learn to make posts that get views?

I think with YouTube, you will get everything you want. On YouTube, you will get to know if the teaching is really working or not based on the video engagement.
