A big one is affiliate marketing , lots of folks are promoting tools like BookBaby or Book Bolt and stacking up passive income. They're also getting smarter with their content by using real-time data to see what works and what flops, then tweaking things fast. Another big move? Diversifying. Instead of just publishing books or content, they're making money through memberships, courses, partnerships, and even selling tools. It's all about building multiple streams so you're not relying on just one thing.
