Here's what's changing:
1. The percentage of AdSense Revenue that Google takes is now being separated into two categories:
* Inventory purchased on the Google Ads platform: Pubs keep 67%
* Inventory purchased on 3rd party platforms: Pubs keep 80%
2. AdSense is moving to CPM My takes on this:
Regarding the shift in revenue percentages: The only change here is in third-party platforms. The revenue cut Google takes from Google Ads revenue isn't changing. So Google is passing on a larger cut of third-party revenue to publishers, so overall I consider this a moderately good improvement — depending on how 3rd party platforms react. Keep in mind though, that most 3rd party platforms are likely to see this as an opportunity to take a larger cut.
As for the shift from CPC to CPM...
This is pretty huge... but it sounds like Google is taking steps to mitigate the impact to publishers.
Obviously, this could play out in a few different ways, depending on how Google charges for CPM on each site moving forward.
One possible analysis is:
Does your site have a large amount of impressions but a low CTR? That *could* benefit you if CPM's were to stay the same.
The trouble is, that's a big "if", because:
Based on our tests, we don’t expect publishers to see a change in their earnings as a result of these updates.
The fact that Google predicts that these changes will have a relatively neutral impact on publisher revenue, suggests to me that they've taken the potential revenue impacts of this shift into account, and they'll be modifying each publisher's CPM accordingly.
So a low-traffic site with formerly high CPC's *should* get a high CPM. And a high volume site with a low-interaction rate, *should* see a relatively lower CPM. But obviously... we'll see how this plays out.
Most importantly ... don't forget the elephant in the room...
What wasn't mentioned in Google's post is the most important event on the horizon for publishers:
Chrome will be phasing out 3rd party cookies beginning in "Early 2024".
Early 2024 just happens to be the same time the above revenue / CPM changes are expected to go through — so one must assume this is all part of one giant shift for AdSense.
Why is this important? Because industry-wide CPM's will likely fall the moment 3rd party tracking is curtailed. (Advertisers aren't going to pay the same amount for less-targeted traffic). So while the above changes from CPC to CPM, and percentages of 3rd party revenue might have some bearing on publisher revenue, the elephant in the room is still the coming Cookie-pocalypse, which will most likely collapse the total net revenue spent on online advertising annually.
To me it looks like Google is slipping in these relatively minor changes along with the coming major change to tracking cookies — which will likely have a far bigger impact on publisher revenue. (And those changes will impact publishers based on the contextual value of site content... but that's a whole other conversation)
My 2 cents, of course.
Good luck everyone. 2024 is going to be a crazy year for all of us.
