Key insights:

Faced with an existential threat to the business model of large swaths of its membership, the Interactive Advertising Bureau is devising new ad targeting methods independent of cookies.

The trade org’s Annual Leadership Meeting kicked off this week with a three-day summit in Palm Desert, Calif., during what is arguably the most crucial moment in the body’s 24-year history. Here, it issued a call to action—dubbed Project Rearc—that urged its members to put consumers at the center of everything they do.

This is because earlier this year, the most widely used browser on the internet, Google Chrome, declared the days of the third-party cookie numbered, joining other providers such as Apple’s Safari and Mozilla’s Firefox in eliminating third-party ad targeting by 2022.

Facing an existential crisis

These changes arose from the growing public scrutiny over how Big Tech uses data, and then takes the resulting insights into billions of people available to advertisers. In the wake of data breaches and public outcry over how companies handle data, lawmakers have started to flex their regulatory muscles.

Smaller ad-tech companies and publishers are also in peril given that third-party data has been at the very core of programmatic advertising since its inception. The vastness of the ad-tech and mar-tech ecosystems has made the sector reliant on such technologies, leaving all but the industry’s walled gardens now facing some existential questions.

The IAB Tech Lab is poised to build upon earlier efforts to come up with an alternative system, hoping to turn what is a tectonic shift in the industry into an opportunity by putting publishers back at the fore of the media business.

Sources tell Adweek this will involve working with publishers to generate a new means of targeting specific audience segments based on first-party data, such as email addresses. These data points can then be hashed to generate a pseudonym for a user, which is then packaged and made available as an audience targeting tool for advertisers.

Also under discussion are protections that can be put in place so that the proposed ID cannot be reverse-engineered to expose personally identifiable information. Plus, it’s looking at an accountability framework that can be applied to all companies in the ecosystem. Discussions also involve functionality that will let users opt out of such targeting, with executives also proposing a consumer-focused education campaign to convince online users of the value exchange in such a trade-off.

Ad tech’s identity parade

Separate proof-of-concept projects along these lines have taken shape over the past year. Both buy- and supply-side platforms have worked with identity providers such as DigiTrust (owned by the IAB), ID5 and LiveRamp to reduce their cookie reliance.

For instance, Index Exchange kicked off a beta test last year that employs targeting methods that can be matched with a number of identity solutions, such as LiveRamp’s IDL, called Publisher Sonar. This “identity library” lets publishers use (or omit) specific audience targeting tools dependent on what the buyer asks for.

Likewise, OpenX (another sell-side outfit) is working with LiveRamp to offer a similar service, dubbed OA.js. Recently installed CEO John Gentry told Adweek these efforts could also result in additional investments in the open source consortium PreBid. “This enables audience creation at the SSP level,” Gentry said.

The rationale for such flexible approaches is an attempt to convince the industry that these offerings can achieve the scalability required to be considered seriously as an alternative to the walled gardens of Amazon, Facebook and Google.

However, while such solutions may benefit from widespread goodwill, the real power remains in the hands of those with a consumer-facing offering.
