Forget the cookie delay — AI is already rewriting the rules of advertising.
While the industry was busy debating yet another postponement of Chrome’s third-party cookie phaseout, AI quietly became the most disruptive force in marketing. But here’s the twist: AI doesn’t work without identity. If marketers want results — real outcomes, not just impressions — they need to prioritize the data that makes AI go.
First-party data strategies are now mainstream. Interoperable identity solutions like Unified I.D. 2.0 (UID2) and ID5 are gaining adoption across the open web. Connected TV (CTV) has grown into a performance-focused, cookieless channel. Contextual and geo-based targeting have become smarter and more scalable. Identity graphs are helping marketers stitch together signals across devices, platforms, and channels.
The foundation for a better ecosystem isn’t being built — it’s already here.
The AI hype is over — and the stakes are higher
It’s no longer buzz. AI is here, and it’s already reshaping how we plan, activate, and measure advertising.
We’re seeing the rise of agentic AI: systems that don’t just surface insights but act on them. These AI agents are identifying patterns, building audiences, optimizing media buys, and analyzing performance. AI is helping marketers stop guessing and start improving.
But there’s a catch — one we can’t afford to overlook.
AI is only as good as the data it works with. “Garbage in, garbage out.” as the saying goes. And in advertising, that means if you don’t know who you’re reaching, even the smartest AI won’t drive results. To unlock AI’s full potential, marketers need a strong, privacy-safe identity foundation.
Identity is the fuel that makes AI work
AI can personalize creative, optimize in-flight campaigns, and even recommend which channels to prioritize — but it can’t do any of that well without context. And context starts with identity.
Identity connects signals from different devices, logins, channels, and interactions to real people. It tells your AI models who you’re talking to — not just what they clicked. That kind of clarity gives AI the power to make smarter predictions, uncover insights, and deliver relevance at scale. Without identity, AI is guessing. With identity, it’s delivering.
Identity is the foundation of the outcomes era
We’re living in a performance-driven age. Impressions and clicks are no longer enough. Marketers today are being judged by real outcomes: incremental sales, customer acquisition, revenue lift, and long-term value.
To measure those outcomes, you need to know who you reached — and whether they took action. Identity makes that connection possible. It links ad exposure to real-world results. It enables accurate attribution across channels. It powers personalization at every stage of the journey, making every impression more valuable.
This is the outcomes era, and identity is what makes it measurable.
Commerce media and CTV show what’s possible
Two of the fastest-growing channels — commerce media and CTV — are great examples of identity in action.
Commerce media
In commerce media, identity helps retailers and marketplaces organize their customer data, enrich it with external insights, and activate it across their own sites and off-site channels. It makes accurate targeting possible and gives marketers a clear ROI they can prove.
CTV
In CTV, identity helps solve a fundamental challenge: turning anonymous viewers into addressable audiences. On free ad-supported streaming platforms (FAST), identity solutions resolve viewership to the household level. On logged-in platforms, identity enriches profiles with behavioral and purchase data, boosting demand, improving CPMs, and growing revenue.
At Experian, we’ve invested in this future. Our recent acquisition of Audigent brings together data, identity, and activation — under one roof — built to support both AI-driven planning and outcome-based performance.
How marketers can win now
To stay ahead in a world defined by AI and outcomes, marketers need to:
Invest in omnichannel identity
To unify signals across platforms and environments.
Make identity actionable in real time
To inform both targeting and measurement.
Utilize first-party data, clean rooms, and privacy-safe partnerships
To future-proof performance.
Tailor identity strategies
To fit their media mix — because what works in CTV may not apply to in-app or web.
It’s not about rebuilding everything. It’s about building on what’s already working.
Final thought: Identity is the bridge
AI is raising the bar, and outcomes are the new standard. But neither works without identity. The marketers who win won’t treat identity as a compliance checkbox — they’ll treat it as their competitive edge.
