Don't bother unless you have money to throw away
I tried both an audio ad on spotify and a couple of banner ads for $20 each {the first ad was $25 because there is $5 dollars audit fee}. Watching my spotify stats it looks like I got no extra plays, as for the other distributors I doubt it. The "click through" rate is abysmal, which makes it way overpriced, I estimate you would have to spend $5000 - $!0000 to see any results. It would be better imho to put an ad online somewhere and pay music listeners $5 or $10 to listen to your album, at least you would know some new people have heard it. Maybe if you were a WELL established artist it would be somehow viable, but something tells me they would use other means. Maybe my songs are trash, but I don't think this is really true.
