How I Built This podcast ranking?

Hey there, I'm curious about the "How I Built This" podcast ranking. Can you tell me a bit more about how it's determined? Is it based on listener engagement, downloads, or a combination of factors? I'm especially interested in how podcasts in the cryptocurrency and finance space fare on this ranking. Does the subject matter play a role in the overall placement, or is it more about the quality of the content and presentation? I'd love to hear your thoughts on this!
