How to sell CPM in AI chat
To sell CPM in AI chat, define an impression as a sponsored product shown and labelled in a delivered answer, cap sponsored products per answer, forecast inventory from relevant request volume, and report chat separately.
Define the impression
Count only delivered, labelled products, not requests that scored but were not shown.
Forecast inventory
Inventory depends on how many requests score highly for the advertiser's products.
Pacing
PA notifies AdOps and the advertiser if delivery falls short; it never changes floors or caps.
Run it with Particular Audience
Sponsored Prompts runs on Adaptive Transformer Search and the open-source ATS MCP server. Advertisers pick products or a collection; each item surfaces automatically, labelled, in chats, prompts and AI searches where it scores highly.
