Microsoft advertisers can now securely preview and share PMax creatives across placements before campaigns go live. #

Microsoft Advertising brought Ad Preview Hub to Performance Max campaigns, giving advertisers a faster way to review and share how ads will appear across placements before they go live.

The feature is designed to simplify creative approvals while helping advertisers understand how assets work together across Microsoft’s AI-powered inventory.

What’s new. Ad Preview Hub is now available within Microsoft Advertising Performance Max campaigns.

Advertisers can access the feature by opening an asset group and selecting Preview ads, where they’ll be able to preview eligible ad formats across different devices and placements. A secure, shareable link can then be generated, allowing stakeholders and clients to review the creative without needing access to the Microsoft Advertising account.

According to Microsoft, only the person who generates the link and those they share it with can access the preview.

The feature was already available for Audience Ads and has now expanded to Performance Max campaigns.

Why we care. Performance Max campaigns automatically assemble creative assets across multiple placements, making it difficult for advertisers and clients to visualise how ads will actually appear. Ad Preview Hub removes much of that uncertainty by letting teams review combinations before launch, reducing reliance on screenshots or third-party approval tools. It also makes it easier to identify assets that don’t perform well alongside others before campaigns go live.

Bottom line. Ad Preview Hub gives Microsoft Advertising Performance Max advertisers a simpler way to preview, review and securely share creative before launch, making stakeholder approvals easier in an increasingly AI-driven advertising workflow.
