When Google feels the need to go public about the state of the current ad revenue ecosystem, you know something’s up.

And “what’s up” is actually “what’s down.” According to a new study by Google, digital publishers are losing more than half of their potential ad revenue, on average, when readers set their web browser preferences to block cookies – those data files used to track the online activity of Internet users.

The impact of cookie-blocking is even bigger on news publishers, which are foregoing ad revenues of around 62%, according to the Google study.

The way Google conducted its investigation was to run a 4-month test among ~500 global publishers (May to August 2019). Google disabled cookies on a randomly selected part of each publisher’s traffic, which enabled it to compare results with and without the cookie-blocking functionality employed.

It’s only natural that Google would be keen to understand the revenue impact of cookie-blocking. Despite its best efforts to diversify its business, Alphabet, Google’s parent company, continues to rely heavily on ad revenues – to the tune of more than 85% of its entire business volume.

While that percent is down a little from the 90%+ figures of 5 or 10 years ago, in spite of diversifying into cloud computing and hardware such as mobile phones, the dizzyingly high percentage of Google revenues coming from ad sales hasn’t budged at all in more recent times.

And yet … even with all the cookie-blocking activity that’s now going on, it’s likely that this isn’t the biggest threat to Google’s business model. That distinction would go to governmental regulatory agencies and lawmakers – the people who are cracking down on the sharing of consumer data that underpins the rationale of media sales.

The regulatory pressures are biggest in Europe, but consumer privacy concerns are driving similar efforts in North America as well.

Figuring that a multipronged effort makes sense in order to counteract these trends, this week Google aired a proposal to give online users more control over how their data is being used in digital advertising, and seeking comments and feedback from interest parties.

On a parallel track, it has also initiated a project dubbed “Privacy Sandbox” to give publishers, advertisers, technology firms and web developers a vehicle to share proposals that will, in the words of Google, “protect consumer privacy while supporting the digital ad marketplace.”

Well, readers – what do you think? Do these initiatives have the potential to change the ecosystem to something more positive and actually achieve their objectives?  Or is this just another “fool’s errand” where attractive-sounding platitudes sufficiently (or insufficiently) mask a dimmer reality?
