Why is my RPM so different across various YouTube channels?
I've recently monetized a new travel channel and noticed that its RPM is significantly higher than my other channels, including a game development channel. My travel channel has an RPM of £6.36 ($8.10), while the game dev channel is only at £1.43 ($1.85). I'm curious about the factors that can lead to such a disparity in RPM across different content types. What are your experiences with RPM on your channels?
