Microsoft is opening AI Max for Search campaigns in pilot next month, expanding AI-powered query matching across Copilot Search, Copilot Answers, and Bing.
The pilot, detailed alongside two other ad product updates, moves Microsoft's search advertising beyond traditional keyword targeting. AI Max uses AI to expand query matching and personalize ad assets for the types of conversational, multi-intent queries that users increasingly bring to AI-powered search surfaces. Microsoft says the system includes brand inclusions and exclusions, term exclusions, and messaging constraints as guardrails, with search term and asset reporting available from launch.
The update mirrors Google's own AI Max for Search. Both companies are rebuilding their search ad products around the same premise: manual keyword targeting cannot keep pace with the way users now search through AI assistants.
Offer Highlights Places Product Details Inside Copilot Responses
Alongside AI Max, Microsoft is rolling out Offer Highlights, an ad format that surfaces product differentiators inside Copilot conversations. The format displays callouts like free shipping, in-store pickup, and product specifications within the flow of a Copilot response rather than as standalone ad units. Microsoft says Offer Highlights is available for retail use cases in English-speaking markets on product detail pages in Copilot, Edge, and Bing.
The approach differs from what Google is testing in AI Overviews and AI Mode. Where Google is placing ad units alongside or within AI-generated answers, Microsoft is embedding contextual product callouts directly into the response flow.
Audience Generation Removes Manual Segment Building
Microsoft is also introducing an AI-powered Audience Generation tool that lets advertisers describe their ideal customer in natural language. Microsoft says the system translates descriptions like “Brooklyn-based consumers aged 20-45 attending concerts and pop-up events” into demographics, locations, and in-market signals without manual segment assembly. The tool is in closed pilot in the U.S. and Canada.
The approach competes with Meta's Advantage+ audience automation and Google's optimized targeting, both of which reduce manual audience configuration. Microsoft's version adds a natural-language interface layer on top of the automated targeting.
A Wider Shift Toward AI-native Search Ad Systems
These updates sit within a broader shift across search advertising platforms. Microsoft, Google, and OpenAI are each embedding advertising into AI-powered surfaces simultaneously. Google is migrating Dynamic Search Ads to AI Max and testing ads in AI Overviews. OpenAI is scaling ChatGPT ads to more markets. Microsoft's three updates collectively position its ad stack for a search environment where conversational queries, AI-generated answers, and automated targeting replace keyword-based search and manual audience building.
