The honest limit, and the new question.
A doctrine is only trustworthy if it states its own limits, so here is NeoNet’s: it does not eliminate adtech. There will always be a residual case — the customer who is in-market but engaged nowhere in the network, searching only on Google, browsing only on Amazon, comparing prices on a marketplace where the brand has no owned or partner visibility. For that genuinely off-network intent, adtech remains useful and is sometimes the only available signal. Paying the tax, for that slice, is rational. The honest test is whether the customer is reachable any cheaper way at all; if not, the auction has earned the spend.
So the doctrine is not never use adtech. It is narrower and far harder to argue with: do not use adtech first for customers you already know. Use owned attention for engaged customers, intelligence for predictable windows, NeoNet for silent customers active elsewhere — and then adtech as the final rung, for the intent nothing cheaper can reach. Adtech is a last-mile detector, not a default one. Used in that position it is a sensible tool; used as the first reflex it is a tax on knowledge you already had.
The question that replaces ROAS
This changes the question a marketing team asks. For years the reflex has been: how do we improve ROAS? The better question, customer by customer, is: why are we paying ROAS at all for this one? If the customer is genuinely new, paid acquisition may be justified. If they are unknown or truly unreachable, adtech may be the only route. But if the customer is already identified, historically valuable and merely silent, the first job is not to optimise the auction — it is to avoid the auction. A brand that asks the second question will find, on inspection, that a large share of its performance spend is being paid to re-buy customers sitting in its own database, drifting through the weakening cells of its own Transaction–Attention Table while no one was watching. That single question, asked honestly of each customer, redraws a media budget faster than any optimisation ever will.
The rule of resort
The whole series reduces to a single rule. Own the intent where you can. Predict it where you can model it. Share it where a partner can route it. Rent it only for what is truly left. Build the Intent Stack in that order and the auction stops being the engine of repeat business and becomes what it should always have been: the last rung, reached for rarely and deliberately. The customer was yours. The relationship was yours. The data was yours. The next intent signal should be yours too. None of this is anti-adtech; it is adtech put back in its place — the last rung, not the first reflex.
