Microsoft Copilot.

Learn what Microsoft Copilot means in modern search and SEO.

Part of speechnounOriginProper noun; Copilot is Microsoft's AI assistant brand across all its products (formerly Bing Chat/Cortana); uses GPT-4 models

Microsoft's AI assistant integrating GPT-4 into Bing Search, Windows, Edge, Microsoft 365, and enterprise products — a major AI search touchpoint for B2B audiences.

Microsoft Copilot is Microsoft's AI assistant brand, powered by OpenAI's GPT-4 models and integrated across Bing Search, Windows 11, Microsoft Edge, Microsoft 365 (Word, Excel, PowerPoint, Teams, Outlook), and Azure enterprise services. Copilot represents one of the most widely distributed AI search touchpoints globally, particularly in enterprise and business environments where Microsoft products dominate.

Copilot in Bing Search

Bing's Copilot integration generates conversational answers alongside traditional search results using real-time web retrieval. Users can switch between 'More Creative', 'More Balanced', and 'More Precise' modes affecting the answer style. Bing Copilot cites its sources, making it similar to Perplexity in attribution — and making content quality and accuracy critical for citation.

Microsoft 365 Copilot

Microsoft 365 Copilot (an enterprise add-on) integrates AI into Word (draft generation), Excel (data analysis in natural language), PowerPoint (slide generation from prompts), Teams (meeting summaries and action items), and Outlook (email drafting and summarisation). For B2B marketing teams, M365 Copilot is increasingly part of the daily content and operations workflow.

SEO Implications of Copilot Growth

Bing's market share, historically 3-6% in the US, has grown with Copilot adoption — particularly in Edge browser default searches on Windows. For B2B audiences (which over-index on Windows + Office environments), Copilot is a higher-priority AI search channel than for B2C. Monitoring Bing Search Console data and optimising for Bing-specific factors supports Copilot visibility.
