The Algorithm Doesn't Know You Anymore

AI agents are becoming the new gatekeepers. Here’s what that means for how brands reach people.

There’s a shift happening that most people haven’t fully registered yet. Increasingly, the thing choosing what you see, what you buy, and what you consider isn’t an algorithm you interact with directly. It’s an AI agent: a layer of machine intelligence that filters, recommends, and sometimes purchases on your behalf.

Lippincott’s 2026 trends report calls this out explicitly: “AI agents are on the rise, increasingly shaping the choices people make. As AI agents increasingly recommend, filter, and choose products on behalf of people, brands must prove their credibility. Trust is what matters now.”

We’re moving from a world where algorithms suggest things to a world where AI agents decide things. That’s a different game entirely.

What This Actually Looks Like

Already, AI assistants handle shopping lists, reorder household basics, surface recommendations based on patterns you never explicitly stated. “Hey Siri, order more coffee” doesn’t involve you browsing, comparing, choosing. The agent makes the call based on past behavior and available data.

Sprout Social’s research shows that nearly one in three consumers now skip Google entirely, starting searches on TikTok, Instagram, or YouTube. Gen Z does this at rates exceeding 50%. Search behavior is fragmenting and AI agents are stepping into the gaps.

What happens when AI agents become the primary decision-makers for low-consideration purchases? What happens when they start influencing high-consideration ones?

The brand that the AI recommends wins. The brand it doesn’t recommend doesn’t exist.

Why This Changes Everything

In the old model, brands competed for human attention. The goal was to interrupt, attract, and persuade. Marketing meant creating messages that resonated emotionally with people who might want your product.

In the emerging model, brands increasingly compete for algorithmic selection. The goal isn’t to persuade a person, it’s to meet the criteria that an AI uses to make recommendations.

These are different skills. Human persuasion involves storytelling, emotion, identity, aspiration. Algorithmic selection involves data, trust signals, structured information, and consistency.

A brand that’s emotionally compelling but poorly structured for AI parsing might lose to a brand that’s less creative but more machine-readable.

What Brands Need to Build For

The brands preparing for this future are investing in what might be called “AI credibility infrastructure.”

This includes: trust signals that machines can verify (reviews, certifications, third-party validations), structured data that AI systems can easily parse, consistent information across all touchpoints, and reputation markers that survive algorithmic scrutiny.

It also includes actual quality and reliability. AI agents will eventually get good at detecting when brands overpromise and underdeliver. The penalty for losing trust with an AI gatekeeper could be permanent invisibility.

The Kantar 2026 trends report emphasizes: “Brands that accelerate their AI visibility strategy in 2026 will be better placed to drive growth.” This isn’t about AI marketing tactics. It’s about being the brand that AI systems trust enough to recommend.

The Human Element Still Matters

Here’s the nuance: AI agents don’t exist in isolation. They serve humans who still have preferences, emotions, and identities. The AI recommends, but (for now) the human confirms.

This means both games matter. Brands need to be machine-credible AND human-compelling. Win the algorithmic filter, then win the human moment of confirmation.

The brands most at risk are the ones optimized purely for human persuasion without machine credibility or optimized purely for algorithmic gaming without genuine human appeal.

What This Means For Everyone

If you’re a consumer, this shift means your choices are increasingly pre-filtered by systems you don’t control and can’t fully see. The illusion of browsing remains, but the selection you’re browsing has already been curated by intelligence you didn’t consciously invite.

If you’re a brand, this shift means the competitive surface is expanding. You’re no longer just competing for human attention, you’re competing for AI recommendation slots. And the criteria for those slots are different, evolving, and opaque.

The algorithm used to be a distribution mechanism. Increasingly, it’s a gatekeeper with preferences of its own.

The brands that thrive in this world will be the ones that understand: trust isn’t just a human relationship anymore. It’s a machine relationship too. And the machines are paying attention.
