I don't know why it's so difficult to find information on how ads and Adsense works with YouTube. Anyway, I found some information that might actually give some insight into what's going on with jewtube and why Amber might not be posting.
tl dr: Companies aren't spending money on ads like they used to, pre-chinky pox. The price of ads are cheaper due to less than normal demand. Less money spent by advertisers = less $ per ad to the YTer.
Also, I wouldn't be surprised if Amber doesn't post a video until next month. Whenever it is that Adsense goes up because of the Holidays, or whatever.YouTube Viewership is Up, But YouTubers Are Earning Less Money
YouTube traffic is on the rise amidst the coronavirus pandemic, but it’s not translating into greater earnings for video creators.
The New York Times reported last week that YouTube traffic is up 15%.
However, YouTube channels are reportedly earning less money amidst a surge in viewership.
The same reason why viewership is up is also the reason why YouTubers are bringing in less money despite increased views.
Pandemic Raises Viewership, Lowers Advertising Rates
As Chris Stokel-Walker points out in a report published to Medium’s OneZero, advertising rates on YouTube have dropped by nearly 50% since the beginning of February.
“Everyone is pausing their campaigns on YouTube,” the report says.
Roberto Blake, a YouTuber who also runs ads on the platform, is quoted in the report saying YouTubers have it worse than others right now when it comes to advertising CPM (the amount of revenue earned per thousand views).
“People I know are going down from $8 to $5.50. I’m seeing people go down from $12 to $4,” says Blake.
Considering the economic uncertainty caused by the pandemic, coupled with a rapidly changing consumer landscape, it’s no wonder companies are reeling in their ad spend.
Why Are Earnings Going Down?
YouTubers earn revenue from people viewing ads on videos, and those views are only worth what an advertiser is willing to pay for them.
Fewer advertisers running campaigns means they will pay less for ads due to reduced competition.
The cost of display advertising is determined by how many advertisers are “bidding” on the inventory.
When there’s many advertisers wanting to pay for the same ad space, it creates a bidding war which drives up the cost of ads.
Conversely, when advertisers pause their campaigns and stop bidding on ads, the cost stays low.
When the cost of ads goes down, revenue for the ad publisher (YouTube & its creators) also goes down.
That’s why YouTubers are earning less even if they’re receiving more views on their videos.
YouTubers Say it’s Getting Bad
YouTube creators themselves have confirmed the reported drop in earnings.
A YouTuber who goes by the name Bodil40, who has over 2 million subscribers, says their CPM has dropped 30-50%. If you do a search for “YouTube CPM” on Twitter you’ll quickly find dozens of video creators who are concerned about their YouTube earnings.
