If you're doing faceless YouTube, just rip the outliers from other people in your niche (maybe add a little of your own twist) and get 1 of 10s instead of trying to come up with ideas by yourself, especially if you have no passion for the niche.
Just retardmaxx, honestly. If you want more AdSense revenue, copying makes more money.
I'm now thinking about setting up something automatic that just scrapes the outlier titles from others then schedules the ideas into the pipeline.
