What Is a Conversational Ad Format?
A conversational ad format is an ad unit built for dialogue: it appears inside an AI conversation and lets the user interact with the brand through questions and answers instead of viewing a static impression. The format matches the medium. In an AI surface the user is conversing, so the ad converses too, rather than interrupting with a rectangle designed for a web page.
This page defines the format itself. For the broader discipline, see what is conversational advertising.
How does a conversational ad format work?
A conversational ad unit renders inline when the conversation shows relevant intent, then contains the entire brand interaction inside itself. Adgentek's Spark format is the reference implementation: a branded card with opener chips, a structured Q&A tree of brand-authored answers, free-text input, and CTAs on every answer. Users explore products without leaving the host conversation, and each interaction deepens the intent signal. Spark averages 3.2 interactions per session.
What types of conversational ad formats exist?
Conversational formats range from fully interactive units to lightweight native placements. The Adgentek Agentic Ad Server supports a full suite: interactive Q&A units (Spark), contextual cards, sponsored recommendations, inline mentions, and conversion-focused action cards. Which format renders is decided in real time based on the surface type and the conversation's intent stage, as covered in how conversational ads work.
How are conversational formats different from static AI ads?
The dividing line is interactivity: static formats are one-way exposures, conversational formats are two-way exchanges.
| Format | Interaction | Intent data |
|---|---|---|
| Static sponsored links | None, one-shot link exposure | None |
| One-way native text ads | None, read-only | Click only |
| Spark (conversational) | Two-way Q&A, 3.2 interactions avg | Structured, per-interaction |

Why do conversational formats perform better?
Because users self-qualify through the interaction. Every question a user asks inside the unit is a declared signal: budget, use case, feature priorities. By the time they click a CTA, they have told the brand what they want. Interactive conversational formats generate 3 to 8x higher engagement than display, and conversational AI inventory has posted 70% higher ROAS and 1.5x stronger click-to-convert versus traditional channels. For brands evaluating the channel, the entry point is Adgentek for advertisers. Across the market, native ads in AI apps are clearing 3-5% CTR; the benchmarks are compiled in our H1 2026 data report.
