Microsoft

Second-largest search advertising platform globally, behind Google, with a broad ecosystem spanning cloud, productivity, gaming, and AI

Microsoft is a technology company whose online advertising platform, Microsoft Advertising, enables advertisers to bid for ad placements across the web.¹ The platform delivers pay-per-click advertising across search engines including Bing, Yahoo!, and DuckDuckGo, as well as on websites, mobile apps, and video.¹ Ads can also appear on Microsoft-owned properties such as MSN, Outlook.com, and LinkedIn.² A LinkedIn integration allows marketers to target users by job title and company, making it a notable tool for account-based marketing and audience segmentation.² Like Google Ads, Microsoft Advertising ranks ads using a combination of maximum bid and click-through rate, encouraging advertisers to serve relevant, effective ads.¹ In May 2025, Microsoft confirmed it would shut down its Invest DSP (formerly Xandr), citing a strategic shift toward AI-driven, personalized advertising suited to a conversational and agentic world as the reason the existing DSP model no longer aligned with its investment priorities.¹ Source 1: wikipedia.org — Microsoft Advertising Source 2: invoca.com — The 2026 Guide to Microsoft Advertising (Formerly Bing Ads)
