The Attribution Cartel
In a piece on AdExchanger, Don Marti coins the phrase the attribution cartel, which deserves to enter the industry vocabulary. It describes a system in which the largest media platforms seek to control not only the sale of advertising, but also the standards used to measure whether that advertising worked.
His warning is especially important because this is not just happening inside private products or proprietary dashboards. It is now being advanced through the IAB TechLab and W3C, where a proposed browser-based standard called “Attribution” would shift more measurement authority toward major platform players including Google, Apple, and Meta.
That should alarm advertisers, publishers, broadcasters, streamers, news organizations, and every independent media owner.
When the same firms sell the media, influence the measurement framework, and report the results, skepticism should be the default. We have seen versions of this before. Attribution systems have a long history of overstating impact because they often measure correlation, not causation. That is not merely a technical flaw. It is a structural conflict of interest.
The consequences reach beyond analytics.
Budgets flow toward whatever gets credited. If dominant platforms shape the crediting system, then legitimate media companies can be systematically undervalued even when they create awareness, trust, brand preference, or future demand. Quality journalism, premium entertainment, audio, television, and independent publishing all risk losing revenue to environments that are simply easier for the platforms to count.
As Marti argues, the danger is broader still: distorted attribution can direct advertising money toward low-quality inventory, misinformation, scams, privacy abuses, and AI-generated clutter, while starving higher-value media that actually serves audiences and brands.
This is why industry bodies should try harder.
Trade groups and standards organizations are supposed to represent the long-term interests of the whole ecosystem, not just ratify whatever is easiest for Big Tech to implement. A measurement standard that centralizes power with already dominant gatekeepers is not in the interest of advertisers. It is not in the interest of publishers. It is not in the interest of competition. It is not even in the interest of better measurement.
There is a better path.
More than a year ago, I argued that ZIP codes could provide the basis for a fairer, privacy-safe, and more universal approach to advertising ROI measurement. ZIP-based randomized experiments can help advertisers measure true incremental impact without relying on user IDs, invasive tracking, or black-box attribution models. With more than 30,000 ZIP codes in the U.S., they also offer far greater statistical flexibility than traditional DMA-based approaches.
The industry does not need the W3C and IAB TechLab to formalize the attribution cartel. It needs independent measurement designed to find truth, not merely distribute credit.
