Does anyone here sell online courses from youtube? If so, could you share your conversion rates directly from youtube viewership?

I'm aware that it depends on the niche, and other factors, and I have done some research online on typical rates on website (usually 0.5-2.5% depending on pricing), but I haven't found many examples from people on YouTube. I'd like to compare my numbers to those converting from there because I feel like I'm doing quite poorly compared to what I could be doing.
