For three decades, media planning answered one question — which channels, in what mix, at what stage? It assumed a human on the other end, scanning a ranked list. Increasingly, an AI makes the choice first. When the chooser changes, the unit of planning must change with it.
For thirty years, digital media planning has answered one question: which channels, in what mix, at what stage of the funnel? You assigned jobs to channels the way a captain assigns roles to players — CTV and YouTube to build awareness, non-brand search to earn consideration, retargeting and brand search to close, loyalty and community to keep the flywheel turning. It was a good model. It assumed something that is quietly ceasing to be true: a human on the other end of the channel, looking at a ranked list, making the choice.
Increasingly, there is an AI between you and that choice. It reads the answer instead of scanning the page. It shortlists the supplier before a person ever sees a brand name. Sometimes it completes the purchase with no human in the loop at all. The web's front door is closing — zero-click searches in the US are now reported as high as 69%, and organic click-through can fall by roughly 61% when an AI Overview sits above the results. When the thing doing the choosing changes, the unit of media planning changes with it, and a plan organised around channels starts to answer a question nobody is asking anymore.
We want to offer a replacement unit. Not a new channel taxonomy, but a different pair of axes — the same two lines we use to map consumer interaction in the agentic era. It works as a single canvas for three decisions the AI age forces on you at once: how you plan your digital media, how you brief your LLM ads, and what agentic infrastructure you must own to shape choice in each state.
We call it the Agentic Consumer Interaction Matrix. It reduces the sprawl of AI-mediated commerce to two questions:
Cross those two lines and you get four interaction modes. Here we treat each quadrant as a distinct media job — a different objective, surfaces, content, and metric — then use the same grid to brief the LLM ad in each state, and to name the agentic infrastructure a brand must own to shape choice there.
Part one
The old funnel is a line. The 2×2 is a field — it plans for a reader who may be a person in one box and a machine in the next.
Read the grid as a media plan and three things fall out that a channel plan hides. The left column is won by conversation; the right column is won by legibility — Q1 and Q3 reward depth, Q2 and Q4 reward brevity and machine-readiness. These are not two settings of the same buy; they are different disciplines with different owners.
The metrics are not interchangeable — and most are new. Judging a Q3 presence by click-through is the AI-age version of judging an awareness channel by ROAS: a category error. And the bottom-right box can quietly delete you.
In Q4 there is no impression to buy and no story to tell. If an agent cannot read your data instantly, you are not outranked — you are simply absent from the decision.
Part two
Before you decide where an LLM ad lives, decide what it has to say — and the biggest determinant is whose brand the conversation has already surfaced.
LLM ads are triggered by context, not bought against a blank slate. Your message enters a conversation already in motion, landing on a consumer — or an agent — who has just heard a brand named. The quadrant sets the stakes; the brand-in-play sets the move. There is a clean rule underneath it:
Read across the grid, that produces eight distinct messaging goals — the actual brief your LLM-ad creative and feeds are written against.
Drive solution clarity. Deepen the consultation and guide the exploring consumer toward the right product in your range, hardening intent.
Win reconsideration. Surface a reason to re-open the question, pull them into your consultation, then drive solution clarity on your terms.
Reinforce and execute. Confirm the choice, remove the last friction, complete the reorder, and extend it (cross-sell, subscribe).
Intercept the transaction. Meet a formed competitor intent with an instant, better-value equivalent — price, availability, delivery — before the command completes.
Move from cited to recommended. Strengthen the citation so the AI names you as the answer, not one of several, and shape the criteria toward your strengths.
Enter the consideration set. Earn a citation where a rival owns the answer, and reframe the deciding criteria so your advantages become the basis of the recommendation.
Win the evaluation. Present machine-readable spec, price, and availability as the optimal match so the agent selects you.
Displace on legibility. Surface as the superior structured alternative in a basket a rival holds, with agent-readable proof of better fit.
Notice that the goal changes by quadrant, but so does the mechanism of the redirect — and it splits along the same fault line as the whole framework. On the human-read left (Q1, and the human side of Q3) you redirect by persuasion and by reframing the criteria of the decision. On the machine-read right (Q2, Q4) you cannot argue at all. You redirect with a legible, demonstrably better offer — price, availability, spec, compliance — at the point of action.
You cannot talk a procurement agent out of a competitor. You can only out-specify it.
This is where "LLM ads" stops being an abstraction and becomes a writable brief. Eight goals, each tied to a quadrant and a trigger, each with its own mechanism — a plan a team can staff and a creative brief a team can execute, rather than a single sponsored line bolted onto last year's funnel.
Part three
The messaging goal tells you what to say. It does not tell you what has to exist for you to be in the conversation at all.
In every one of these states, the consumer's choice is now shaped — or forfeited — by a piece of brand-owned agentic infrastructure that is either present or absent. This is not an ad you buy. It is a capability you build, and it is the thing that earns a brand the right to nudge the decision in each state. So the third pass over the grid is not a media buy but a build order: which piece of agentic infrastructure must exist for you to shape choice in each quadrant, and what its job is once it does.
Branded × Exploratory — the choice is shaped inside a consultation. To run that consultation yourself — reading the circumstance, refining the criteria, steering toward the right product in your range — you must own a vertical agent built on your first-party data. Build it and you inherit the skilled-salesperson role and the Authenticity Premium with it. Fail to, and a generalist AI runs the interview instead, deciding for the consumer what only your expertise should.
Branded × Solution Clarity — the choice is already made. The infrastructure's job is to execute it frictionlessly and keep it safe. You must own the rails — WhatsApp and UPI, voice reorder — and a guardian-agent governance layer that lets a customer delegate the repeat purchase without losing control of it. The nudge here is not persuasion; it is the removal of friction and the trust that makes delegation feel safe.
UnBranded × Exploratory — a generalist AI shapes the choice. And it will only shape it toward brands it can retrieve and trust. That surface is infrastructure you own: Answer Engine Optimization — structured schema, semantic completeness, well-sourced authority — that makes the model surface and cite you inside its synthesised answer. Without it you are not outranked; you are simply not in the answer the consumer sees.
UnBranded × Solution Clarity — a procurement agent shapes the choice, no human in the loop. The only thing that shapes it is legibility. You must own the interface — structured product feeds, MCP/A2A endpoints, JSON Agent Cards, real-time price and availability APIs, the Dual Search Optimization pairing of bot-readable pages and live data portals. In enterprise IT procurement, the supplier whose specs, pricing, and certifications are clean structured data makes the basket; the one whose data is trapped in a PDF brochure is never evaluated at all.
Read this way, the plan stops being a spend and becomes a set of capabilities you either possess or you do not. Each quadrant names a piece of agentic infrastructure that must exist before you can influence the decision — a consultative agent, a commerce rail, an answer-engine presence, a machine interface — and the grid splits cleanly into infrastructure that shapes a human's choice through conversation (Q1, Q2) and infrastructure that shapes a machine's choice through legibility (Q3, Q4).
Most brands have built little of it. That is the real gap the grid exposes: not underspend, but under-capability.
The through-line
Step back and the deeper structure appears. The 2×2 quietly separates two media systems that used to be one. On the left and top, human attention still lives, and persuasion still works — the craft of a great advisor, a great offer, a great story. On the bottom and right, machine attention takes over, and persuasion gives way to legibility, structure, and price. Most organisations are fluent in the first system and illiterate in the second, and they cannot see the imbalance because their channel plan never had a column for it.
A channel plan tells you where you are spending. This 2×2 tells you which kind of choosing you are spending against — human or machine, conversation or citation, persuasion or parseability — and it forces the honest question underneath every AI-age media decision: for each of these four jobs, are we present, absent, or merely assuming a human will still be there to notice us?
The consumer will not stay in one box. They slide from discovery to consultation to execution inside a single journey, drifting across the axes as their intent hardens and their brand affinity forms — the fluid behaviour every modern audience now exhibits. A media plan built on channels cannot follow them. A media plan built on these two axes was designed to.
Draw the two lines first. Then build the plan.
