Whether we like it or not, third-party cookies on Google products will be leaving us shortly (although the “when” element of this question remains to be seen- first it was 2023, now it appears to be at least 2024).
With this comes a lot of uncertainty about just what happens after that, as third-party cookies are used for so many things. For bloggers, one of the biggest uses of third-party cookies revolves around all things ad revenue, as these cookies are used for targeted advertising on our sites based on user's search history. The better the targeting, the higher ad rates you have historically achieved (and we're talking serious money here- my single best day was $83.90 RPM).
The shift to first-party data will change a lot of this, and ad services, like Google's exchange, are testing a variety of new targeting methods to help deliver ads to users while keeping their privacy in mind.
Naturally, this will impact earnings. Google tests have shown that there could be a collapse in ad revenues upwards of 60%, while others, like Mediavine, counter that first-party cookies will only impact Chrome traffic (as other browsers have already phased out 3rd party cookies) and that Chrome accounts for roughly 63% of market browser share outright (although it is 35-50% on our sites). So that 60% drop may be more like 20% to 40% for most of us once the dust settles.
The good news is that these figures are all based on cookies disappearing and no other solutions coming about. Ad networks, like Mediavine, are working hard on first-party solutions to help protect member revenue (and even improve it!) after the switch. The bad news is that the same may not be able to be said for those on other ad networks, as it will likely take time for everyone to settle on what is the “best” solution.
In this one, we wanted to mostly ignore what ad networks are doing for a minute and instead focus on what you can do as a blogger to be prepared for the first-party cookie switch. The solution to this revenue problem is on us as much as on our ad networks!
