Advertising Is a Cloud Science: The Myth of Precision in Ad Tech

Alessandro De Zanche

Mar 23, 2025 — 1 min read

In this episode of the 'not just ADZ' podcast, Erez Levin, an ad tech veteran, and I try to explore what "quality" in digital advertising really means.

Advertising has long pretended to be a clock science: something measurable, predictable, and precise. But in reality, it's a cloud science: often unpredictable, probabilistic, and shaped by dynamics we can't fully observe or control.

Yet, the industry still clings to rigid attribution models and promises of exact incrementality, even when the tools used and the quality of the outcomes are eroding before our eyes.

Cookies are hanging on, but their effectiveness is diminishing by the day. By postponing a serious confrontation with this reality, the industry is merely extending the life of a measurement approach that was never built to last. We are often essentially tossing coins and calling it the scientific method, an uncomfortable truth many would rather not acknowledge.

Erez and I discuss, and in some areas have different perspectives, what Erez calls the digital advertising "Quality Trifecta" (see diagram below).

Then we tackle another persistent myth: the notion of infinite supply. As a clear prime example of this, for years, the programmatic ecosystem has sustained itself by purchasing fake in-stream ads and marketing it as premium. But that model has a breaking point.

This conversation explores what happens when those myths start to fall apart. Not theoretically, but in a "this is already happening" kind of way.

Erez and I assess the reckoning that digital advertising faces and, more importantly, draw a vision of what building on more honest foundations might look like.

Because DSPs manage programmatic ad spend, they can be seen as gatekeepers wielding influence over industry standards. DSPs select inventory to bid on, interpret SSP signals and prioritize bids based on historical performance and preferences. However, advertisers, agencies, media owners and technology providers also influence the rapidly evolving programmatic ecosystem.

Trust, Privacy & Data Ownership with David Kohl

For years, the advertising industry has been trapped in a cycle, reacting to shifting regulations, privacy changes, and platform policies rather than proactively shaping its own future.

"And so the question is not how to avoid using data, because that ship has sailed. The question is, how do we use data responsibly? How do we use data while respecting people’s preferences? How do we provide transparency on the data we use? That's the
