YouTube shorts RPM are at the level of a few cents, but you will get a lot of subscriptions on them. New viewers will also watch long videos, so this should convert into additional earnings there as well.

You have a good RPM. In comparison I have about $1, but I usually do 2-4 minute graphic visuals, so I don't have ads in the middle. RPM depends mainly on the topic of the video and the highest are in niches related to business and finance.

I just wrote an article about AdSense earnings on YouTube, and in my data there is one channel about travel that has $3.78 RPM, so similar to yours, but these are 2023 earnings, and in your stats they are from the beginning of the channel or from this year?
