This is a bit late so you probably already know what it’s like at this point but yeah:
The CPM is really low. Talking like .11 USD per 10k low. It’s definitely not a viable source of income for smaller creators like youtube CPM might be. It’s probably due to the fact that tiktok ads are far and few between. It kind of balances in out in how tiktok views are very accessible and much better in the short term than youtube views.
It just takes so much more to get a banger on YT, twitter, insta, and the like.
