Is Marketing (Still) for Humans?

As AI agents or assistants gain widespread adoption, the roles and responsibilities they play in assisting humans disrupt established convictions around human-to-human interaction.

One area of interest is marketing.

For generations, marketing has been the vehicle a brand uses to convince people to buy or trust their product. At its core, a brand tells people about something they have and persuades them to buy or use it by building trust.

In the past 100 years, the channels may have changed significantly, but the audience hasn’t. It’s always been humans who decide whether or not they’ll be influenced to make a purchase.

So with the proliferation of millions of AI agents running tasks from personal computers, handhelds, and even smart glasses, it bears asking, is marketing (still) for humans?

My answer was initially “Yes! Marketing is for humans.” And to a certain degree that’s true. But is the answer that simple? No. No it’s not.

Trust is now proxied

In 2026, any human can spin up an agent to handle a spectrum of the most mundane, household tasks all the way to personalizing their own health care. The human should have limited management of the decisions their agent makes for them or else it undermines the very power an agent expects: autonomy.

An agent’s autonomy is powered by human trust. The human can’t and shouldn’t evaluate every vendor or decision their agent interacts with. Therefore they confer trust to empower their agent as an autonomous assistant. This means that agent trust becomes a pre-requisite for human trust.

Brands increasingly have to earn the trust of the agent in order to market to humans, effectively.

In marketing, you always want to “be where the eyes are.” If the human’s eyes are glued to their screen during the Super Bowl, then you buy 30 seconds of ad time. If they’re strolling down New York’s Times Square, then you want the largest billboard. But if they’re on vacation swimming while their agent is on their laptop in the hotel room running tasks, their eyes or attention are not available.

Brands have to appeal to the agentic layer as a minimum requirement of marketing. Humans trust the agent they picked, and that agent has permission to ignore or amplify your brand in its discovery.

The flow of trust is now Human > Agent > Brand.

Convince the agent. Convince the human.

Agents are the new gatekeeper.

Agents can't feel. To feel is human.

Therefore, digital marketing that prioritizes human emotion and is intercepted by an agent will be parsed based on its data, not its use of memes, mascots, and mottos.

An agent can't be manipulated by a song, scent, or sales pitch. It has an assignment given to it by a human to research and provide a concise list of options, and in many cases chooses the one it deems appropriate based on the policy given to it.

This does not mean that marketing that appeals to human emotion will be displaced. It just serves as a reminder to brands to be aware of your audience. Like a human personal assistant that handles the shopping and management of their employee, an agent also holds a similar power dynamic that has to be acknowledged.

Brands that fail to understand the autonomy an agent provides will build the most trustable, yet invisible brand. Emotional branding will continue to exist, but its efficacy will be challenged online if it encounters an agent first.

Those who invest in agent legibility or the ability for agents to accurately evaluate your brand offering through structured data, accurate metadata, API-accessible information, and LLM-readable content will win the trust of humans.

Agents can read. They just don't read with their hearts as humans do.

Agent Credibility

So what should brands do? How could they ensure that agents choose them when given permission to do so?

Let's consider how a human purchases today with a common, yet simple example of choosing a restaurant. The average human will ask a friend for a referral, then search online for options such as Googling “restaurants near me.”

Once there's a clear list of options, they’ll reduce that list based on appetite, budget, and reviews or ratings. The reviews arguably matter the most. They provide the diner with something invaluable: credibility.

In an agentic future, brands will have to establish the same protocol. A system in which agents or autonomous assistants can experience the same confidence needed to choose the most relevant option.

I call this process agent credibility.

Agent credibility is the degree to which an AI agent can accurately evaluate, verify, and confidently surface a brand to its human.

SEO and AEO (Answer Engine Optimization) both assist in this by increasing the chance for discovery in search results. However, discovery doesn't guarantee adoption. It's just the first line of defense and minimum requirements in ensuring an agent deems you credible.

Think of it like street cred or industry standing. When a person or product has passed the reviews of others credibility is established and is then transferable.

The future will require brands to gain agent credibility through SEO and AEO first, followed by establishing relevancy that the agent can pass on to the human with confidence.

The model becomes discovery > relevancy > credibility.

Final Thoughts

Marketing is still for humans. However, the path to human attention and trust, is increasingly filtered through agents.

The end goal is still to gain human trust. The new challenge is to convince an agent to assist your brand in earning it.

Brands now have two audiences they must satisfy simultaneously, and most are only building for one of them.
