What the eMarketer Future of Digital Summit Taught Me About Marketing in the AI Era
The future of discovery is just a keystroke or a “chat” away. At the eMarketer Future of Digital Summit, one thing was clear: AI is no longer a tool on the margins — it’s at the center of how consumers search, decide, and engage. Marketers must adapt now
Talk of AI being incorporated into marketing has been around for years, but attending the Future of Digital Summit in New York earlier this month really brought home how quickly it’s moved from hype into reality. What struck me most wasn’t just the technology—it was how fundamentally consumer behavior has already shifted, and how unprepared many marketers are for what comes next.
Over the course of the day, I heard from eMarketer analysts, CMOs, agency leaders, and platform executives. The common thread? Discovery is changing at a pace we’ve not seen since the early days of search or social media. That has big implications for anyone in content and marketing. Here’s my four big takeaways from that day.
1. Consumers Trust AI More Than We Think
One of the most eye-opening stats came from Nate Elliott, Principal Analyst at eMarketer. He shared that their research shows that nearly half of US consumers already use generative AI every month, and over 80% trust AI responses as much or more than traditional search results.
Think about that for a minute. For nearly two decades, Google was been the default for finding answers. Now, millions of people are just as comfortable asking a chatbot. And they’re not just using it for curiosity—they’re relying on it at every stage of the customer journey, from discovery through to purchase decisions.
For marketers, that means we can’t treat AI as a side project. It’s already a mainstream channel for discovery.
2. Search Is Fragmenting Beyond Google
Sarah Resnick of Western Union reminded us that search is no longer one-size-fits-all. Consumers—especially younger ones—aren’t starting with Google. They’re asking TikTok, watching explainer videos on YouTube, or typing conversational prompts into AI tools.
That’s a fundamental shift. For years, we optimized content for keywords and rankings on a single platform. Now visibility means being everywhere: structured content on your website, thought leadership in the press, validation through user-generated content, and presence in the channels where different generations actually search.
The foundation of SEO still matter: schema, technical hygiene, authoritative content e.g. follow EEAT principles but it’s no longer sufficient on its own.
3. Attention Has Replaced Engagement
Benoit Vatere, CMO of Liquid Death, was blunt with his message: brands expect too much from a single ad. Social has become too focused on bottom-funnel outcomes, as if one post can take someone from awareness to purchase. That’s not how people actually behave.
He pointed to the “90/9/1 rule”—90% never engage, 9% engage lightly, and 1% engage heavily—and urged brands not to design for the 1%. Engagement isn’t about likes and comments; it’s about capturing and shaping attention at scale.
This theme came up again with TikTok’s Dina Liu, who described the phone as the “rift screen,” pulling more attention than TV. For marketers, the implication is clear: digital is no longer the secondary screen. It’s the primary stage.
4. Authenticity Is the Currency of Trust
Caroline Proto from EssilorLuxottica put it simply: PR is more important than ever. Why? Because LLMs are pulling from a wide ecosystem of sources. If your brand isn’t being talked about in credible places media, reviews, creator content you’re less likely to show up in AI-driven results.
Consumers are also savvy enough to know where answers come from. They’re looking for authentic signals and cross-checking them with UGC and creator content. That makes authenticity, once a nice-to-have, an essential part of discovery strategy.
5. Measurement Is Messy (and That’s Okay)
Caroline Proto captured the prevailing thinking about incorporating perfectly: “We’re building the plane while flying it.” Measurement in AI discovery is immature. We can’t always connect impressions in AI results directly to outcomes. Benchmarks are shifting under our feet.
That’s uncomfortable, especially in a performance-driven world. But it’s not unprecedented. Proto compared it to the early days of mobile, when traffic was small and difficult to quantify—until suddenly it wasn’t. The same will happen here. The key is to experiment transparently, educate leadership, and reset expectations.
Lessons for Marketers
Pulling all this together, I came away with four big lessons for anyone in digital marketing today:
Treat AI as mainstream, not emerging. It’s already influencing customer journeys.
Broaden visibility. Don’t just optimize for Google think ecosystems, UGC, and PR.
Design for attention, not vanity metrics. Likes are meaningless if no one remembers you.
Stay adaptable. Measurement will lag. Experiment, share learnings, and keep educating stakeholders.
Final Thought
The summit reinforced to me that we’re entering a big, new phase of digital marketing one where AI, authenticity, and attention sit at the center. Brands that cling to old funnel models or over-index on vanity engagement will struggle.
The opportunity for content marketers, publishers, and agencies is to lead in this space: to help brands navigate AI responsibly, produce content ecosystems that earn trust, and connect creative storytelling to business outcomes.
It’s not about having all the answers yet. It’s about showing up where discovery happens, experimenting thoughtfully, and keeping strategy grounded in authenticity.
That’s how we’ll try to fly this plane while also still building it.
