Take this with a grain of salt because it’s what some guy on the internet (me) “remembers reading something about, once”, but adblock rates on the general internet, were around 3% or something similar (can’t be bothered, please look it up yourself)
Therefore, I really wouldn’t hope for such an insane number as 15% on YouTube.
