Microsoft Advertising has opened its AI Max for Search pilot to all advertisers in May 2026, placing search ads inside Copilot conversations and Bing AI Answers for the first time at scale. The rollout comes alongside two new capabilities: Offer Highlights, a format that surfaces product differentiators inside AI responses, and Audience generation, an AI-powered targeting tool. For brands running multi-platform GEA strategies, the Microsoft expansion changes the calculus significantly.
AI Max arrives on Copilot
AI Max is Microsoft’s AI-driven expansion layer for Search campaigns. In practical terms, it takes existing search campaigns and extends their reach into AI surfaces: Copilot Search and Copilot Answers, the conversational interface embedded in Bing. The open pilot in May 2026 means any advertiser running Microsoft Advertising campaigns can activate AI Max and begin appearing inside Copilot interactions.
The mechanism is similar to Google’s AI Mode approach: AI Max uses query matching, asset personalisation, and URL routing to determine when and where to place ads within AI-generated responses. The key distinction is the query profile of Copilot users. Questions asked in a conversational AI interface are typically longer, more nuanced, and further along in the decision journey than a standard keyword search. AI Max is built to interpret that nuance and surface relevant ads within the contextual response.
Offer Highlights: a new format for conversational AI
The most concrete new product announcement is Offer Highlights, a format that appears inside Copilot conversations. Offer Highlights surfaces specific product differentiators — such as free shipping, in-store pickup availability, or key specifications — directly within the AI-generated response. Best Buy is among the first advertisers to activate the format.
The significance is that Offer Highlights moves beyond traditional “click here for more” ad placement into contextually relevant information delivery. A user asking Copilot a research question about a product category might see factual differentiator information from a participating brand alongside the organic answer. The format blurs the line between information and advertising in a way that standard search display formats cannot.
Audience generation: AI-powered targeting
Microsoft is also piloting Audience generation, a targeting tool that inverts the traditional approach to audience building. Instead of defining audiences through demographic selectors and interest categories, advertisers describe their target customer in plain text. Microsoft’s AI interprets the description and translates it into audience targeting settings.
The practical benefit is speed and accessibility. Building precise audience definitions typically requires significant expertise in Microsoft Advertising’s targeting architecture. Natural language input removes that barrier and makes sophisticated targeting available to smaller teams, a meaningful step toward the kind of AI-native campaign management that is becoming standard across platforms.
Why Copilot matters for GEA strategy
Google AI Mode receives the most attention in GEA discussions, but Bing Copilot represents a meaningful second surface. Microsoft’s Copilot is embedded across Windows, Edge, Microsoft 365, and Teams, reaching a user base with disproportionate B2B representation. Corporate users who interact with Copilot inside Microsoft 365 are exactly the audience many B2B brands are trying to reach — and they are now reachable through AI Max placements.
For GEA strategy, the Copilot expansion means AI Mode campaigns and Copilot campaigns can run in parallel with comparable tooling. The open pilot removes the last friction point. A genuine multi-platform GEA approach, one that reaches buyers wherever they search with AI, is now technically achievable for any advertiser with an existing Search campaign budget.
