What’s New with Microsoft Ads + Copilot: March 2026

Table of Contents

Let’s dive straight into Microsoft quietly rolling out AI-native formats and surfaces that many brands are not taking advantage of yet.

What’s Changed

New AI-driven ad surfaces

Microsoft has introduced new ad placements across Bing, Edge, Microsoft Start, and other Copilot‑adjacent experiences. These placements can appear near AI‑generated answers in search-like contexts, though they are not displayed alongside private Copilot conversations.  

Access to these formats isn’t fully self-serv yet. Availability varies by campaign type and is being rolled out gradually. Reporting breakouts for AI placements are available in some campaign views, though they’re not always surfaced prominently.

Takeaway: New inventory exists, but you’ll want to verify what’s actually available in your account.

Showroom Ads

Showroom ads let users explore products, compare options, and ask questions within the search experience. All without clicking through to a landing page.  

Early Microsoft data shows these formats driving significantly higher engagement and conversion rates compared to standard search ads.

Takeaway: Worth testing for retail brands already active on Microsoft Ads.

Copilot Checkout

Copilot Checkout allows shoppers to move from AI‑assisted research to purchase without leaving the Microsoft experience. The merchant remains the merchant of record.  

Shopify merchants are automatically eligible, and others can apply.

Takeaway: The checkout moment is moving closer to the research moment. This is particularly relevant for those already capturing meaningful Bing shopping volume

Brand Agents

Brand Agents allow companies to deploy a trained AI assistant on their site that understands product catalogs, brand voice, and common customer questions.  

Performance from AI‑assisted sessions are tracked separately, giving visibility into how guided interactions compare to standard browsing.

Takeaway: This is a site-side feature that’s worth evaluating on its own merits.

Copilot for campaign management

Copilot within Microsoft Advertising can generate headlines, descriptions, keyword suggestions, and even custom images from a landing page URL.  

Campaign builds that once took nearly an hour can now take minutes. Reporting that required manual work can be produced from a short prompt.

Takeaway: Useful for initial builds and copy drafts. It’s best to treat it as a starting point for creative and copy. It should not be a substitute for hands-on campaign management.

What This Means for Your Digital Presence

Is Microsoft the only AI-native ad platform at scale? Not quite. Google has moved aggressively with AI Overviews, Performance Max, and Demand Gen, all with significantly more volume. Microsoft’s formats are more novel in some ways, and they’re genuinely incremental because most advertisers aren’t running both platforms.

The economics still favor early movers, for now. Microsoft CPCs remain lower than Google’s, and competition on AI-adjacent placements is still light. If you’re already running Microsoft Ads and have clean feeds and creative assets, testing these formats now has a reasonable cost-of-entry. If you’re starting from zero on Bing, the baseline volume question comes first.  

For retail, the conversion surface is expanding. But, only for brands already positioned on the platform. Merchant Center needs to be current. Product feeds need to be clean. Those are the real prerequisites.

What We’re Focusing On

AI Surface & Placement Audit: Reviewing how existing Microsoft campaigns appear across new AI‑driven surfaces and identifying which campaigns types are actually eligible.

Copilot Checkout Activation: Ensuring product feeds, Merchant Center setup, and Shopify integrations are ready for activation where volume justifies it.

Showroom Ad Creative Readiness: Building the visual and narrative assets for brands already seeing meaningful Bing shopping activity.

Incremental Reach Measurement: Developing attribution frameworks that quantify what Microsoft delivers on top of Google.

Healthcare Audience Mapping: Aligning Bing’s demographic strengths with patient and HCP personas to identify where incremental reach is realistic.

An important final note

Bing only holds roughly 10% of search market share. That means even if Microsoft’s AI ad formats perform well, the volume ceiling is real.

That said, if you are already on Microsoft Ads, above are some genuinely new surfaces worth understanding.
