I have no idea where you are getting the $20 per 1000 views number from as no source is given. I have no private information on the topic as I do not run ads on Youtube or run a Youtube channel, but that does not seem to conform to any of the publicly disclosed information from Youtubers that I have ever seen in common entertainment categories. As seen in the video I showed, a channel targeting Finance does average ~$20 per 1000 views, but those are relatively narrow demographics and nowhere near the most common content. Do you have a advertising account on Youtube and the $20 is the number you are being quoted for a ad campaign? If so, is it targeting a high value, competitive demographic? Otherwise, what is the source of the $20 per 1000 views number?
