The breakdown is not gradual. It is systemic.
- Targeting loses relevance:
Legacy systems depend on historical signals: Past Searches, Behavioural Patterns.
But in conversational AI, intent is immediate and explicit. “The user is telling you exactly what they need right now,” Baird notes. And yet, traditional systems have no mechanism to truly interpret that signal in real time.
- Placement becomes fragile:
In static environments, poor placement is a missed opportunity. In conversations, it is a disruption. “A forced insertion at the wrong moment… destroys the trust that makes the app valuable,” he explains.
- The funnel no longer fits:
Search ads assume purchase intent. Display assumes awareness. But AI conversations sit somewhere in between — exploratory, iterative, unresolved. “Legacy systems weren’t built for that moment because that moment didn’t exist as an ad surface before.”
The conclusion is difficult to avoid. This is not a format problem. It is an architectural one. And as Baird puts it plainly: “You can’t retrofit a static-page logic into a live conversation. It has to be native by design.”
The Trust Equation: Transparency as a Performance Lever
If structure is breaking, trust becomes the stabilising force.
The concern among publishers is clear: Ads embedded within AI responses risk blurring the line between assistance and influence. But the tension, Baird argues, is often overstated — a false tradeoff shaped by past mistakes.
“The publishers who’ve burned trust with ads did it through unmarked placements, irrelevant interruptions, creative that looked like part of the response but wasn’t.”
In other words, the issue is not advertising itself, but poor design.
When those mistakes are corrected, the dynamic shifts. Ads that are clearly labelled, contextually aligned, and introduced at the right moment do not feel intrusive. They feel useful. Even welcome.
“What we’ve found is that when an ad is clearly labelled, contextually relevant, and shows up at the right moment… users don’t resent it, they actually engage with it.”
The data reflects this shift. Engagement rates in conversational environments are outperforming traditional formats, not despite transparency, but because of it.
The implication is subtle but important. In a conversational interface, relevance is not just a targeting advantage. It is a trust mechanism. And trust, in turn, becomes a performance driver.

For some platforms, the move toward LLM-native advertising has not been an experiment, but a necessity.
