AI is rewriting the rules of searchand that means it’s time for marketers to rethink the rules of engagement. We’re entering an era where platforms backed by billions in investment are changing how people get answers to their questions, make decisions, and explore the world—online and in-person.
Google isn’t going anywhere, but its grip on consumer behavior is facing new pressures. What’s emerging is a layered experience—one that blends traditional search with AI-native assistance.
So what does this shift mean for the marketing funnel? And more importantly, how should marketers respond?
One journey, two behaviors

The reality at this point is that people aren’t replacing Google with AI—they’re using both, just in different ways.
Think of someone planning a trip. They start with a Google search—something like “cheap island vacations.” It’s quick, broad, and meant to spark the imagination. But as the idea takes shape and they move closer to booking, their behavior shifts. Now they’re turning to an AI tool: “Create a 7-day itinerary to the Bahamas with top beaches and snorkeling spots.” That’s not a search—it’s a request for a plan. Same person, same goal, but two very different moments in the journey.
Google still dominates the early stages of exploration. It’s where curiosity begins and ideas take shape. But as people move closer to a decision, behavior shifts. AI tools are stepping in—guiding choices, offering recommendations, and helping users take action in real time.
And the market is paying attention. According to Emarketer, AI-driven search ad spend is expected to reach $26 billion within five years. That level of investment doesn’t just follow hype—it follows consumer behavior. And that behavior is already changing.
The new full-funnel playbook
With search and AI each playing a distinct role in how people move from discovery to decision, marketers need a new playbook. The shift doesn’t just change where we show up—it changes how we plan, create, and measure across the entire funnel.
