Neil Patel looks like a goober. He's also amazingly smart at digital marketing and he's got a knack for explaining marketing strategies clearly so anyone can follow them (and he's worth giant piles of cash). He recently put out a blog article about using SEO (search engine optimization) on Amazon pages. The concepts are solid for anything you're selling on Amazon, including elf games for goobers.

FYI, there's one article, but I highly recommend clicking on his various links inside the article because those topics will also help you max out your SEO within Amazon.
I suspect most of the same suggestions will work with DriveThruRPG.
