How to run AI ads without keywords
To run AI ads without keywords, let the advertiser pick products and score each product against the meaning of every incoming request. High-scoring products enter the auction; the rest are skipped.
Why keywords break in chat
Shoppers ask in full sentences, with constraints and context. No keyword list can cover every phrasing.
How meaning scoring works
Adaptive Transformer Search represents requests and products as meanings and scores how well they fit. A threshold decides eligibility.
What advertisers gain
Reach on phrasings they would never have bought, without wasted spend on poor matches.
Optional include and exclude terms
No keywords are required, but advertisers can optionally add include terms (prompts, keywords, queries or strings) to make sure matching requests are considered, and exclude terms to block contexts they never want. Excluded terms always win. Include terms never bypass the retailer's relevance floor, caps or category rules.
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.
