Media Buyers Remain Hesitant on Alternative IDs as Google Delays Cookie Phase-Out

In a surprising twist, the urgency surrounding alternative identifiers in digital advertising has significantly cooled. Media buyers, initially eager to explore alternatives due to anticipated changes in cookie policies, now find themselves less motivated following Google's recent decision to postpone its cookie deprecation timeline.
Kyle Holloway, senior vice president at IPG Mediabrands’ data division Acxiom, highlights the mixed reactions from buyers. "With Google scrapping its cookie cutoff deadline, client inquiries about a cookie-less landscape have dwindled, and the urgency has all but disappeared," he remarked.
Current stats reveal that as of January, alternative identifiers are integrated into approximately 70% of cookie-less bid transactions, a slight increase from 65% in October, according to Bidswitch. Essentially, most impressions available are now at least partially linked to alternatives to third-party cookies.
Mathieu Roche, co-founder and CEO of ID5, noted that usage tends to mirror availability, but there remains a noticeable delay in adoption. "There's a gap between ad tech firms providing alternatives and media buyers implementing them," he explained.
The Cookie Conundrum Continues
The ongoing presence of third-party cookies, particularly in Google’s dominant Chrome browser, has caused some advertisers to hesitate. Historically, many have relied on cookies for targeting and measurement, creating a reluctance to abandon what’s familiar. Rory Latham, senior director at GroupM, estimates that cookies still account for up to 50% of impressions in the programmatic bidding environment, with Bidswitch data indicating that cookies are present in approximately 80% of Chrome's traffic.
Another factor contributing to media buyers' slow shift toward alternative IDs is the development of new strategies to circumvent cookie usage. Retail media networks offer first-party audience data, while other companies are opting for context-based targeting methods that do not rely on cookies.
Alex Block, executive vice president of programmatic at Jellyfish, emphasized the company's commitment to exploring solutions that don’t depend on traditional IDs, highlighting a transition towards innovative advertising strategies.
Yet, many advertisers—especially those outside the S&P 500—are grappling with the transition, often questioning the investment required for upgrading their data strategies. Alison LeRoque, vice president at independent media agency Novus, reported that smaller marketers are more likely to wonder if such investments are necessary when measuring ROI against their smaller budgets.
Balancing Performance and Precision
Despite these challenges, it is essential to note that media buyers are not entirely dismissive of alternative identifiers. Tinuiti's Harry Browne indicated that a substantial portion of his agency's streaming TV purchases involves alternative identifiers, particularly The Trade Desk’s Unified ID 2.0. He maintains that Google’s deadline postponement hasn’t altered their approach toward alt-ID adoption.
However, assessing the extent of alternative ID usage and understanding the gap between supply and demand remains complex. Latham indicated that bid throttling—a method preventing full inventory availability from supply-side platforms—can obscure the true presence of alternatives in the bidding landscape.
Ultimately, performance takes precedence in this evolving market. As advertisers prioritize precise targeting amidst rising operational costs and competition, there’s a diminished focus on the intricacies of data mechanisms. "Clients care primarily about their KPIs," Latham noted, highlighting the trend towards measurable results over cookie-less strategies.
It's apparent that as long as Google withholds clarity on third-party cookies, the adoption of alternative IDs will continue to taper off. The landscape remains fluid, but the immediate future suggests a cautious approach from media buyers, driven more by performance than by pushing for innovative solutions.
