What are the main features of Bing?

Bing Chat Enterprise, which adds advanced features for organizations, will cost $5/user/month. Microsoft 365 Copilot at $30/user/month includes Bing search across Excel, Word, Outlook, and Teams.
What are the best alternatives to Bing?
Google is the dominant alternative with 90% market share, stronger index coverage, and more natural language understanding for complex queries. For Microsoft-integrated search, there is no direct alternative. Specialized alternatives like DuckDuckGo (privacy-focused), Perplexity (research-focused), and Brave Search (independent index) serve different use cases.
Who is Bing best for?
Bing is best for Microsoft 365 enterprise users who want Copilot to search company documents and emails alongside public web results. It is also valuable for SEO professionals optimizing for both Google and Bing (AEO strategy). Bing is less suitable for users needing the broadest possible index coverage or most current information on obscure topics.
Does Bing have an API?
Bing Search APIs were deprecated and sunset on August 11, 2025. Microsoft recommended alternatives including Azure Cognitive Search (enterprise full-text search) and OpenAI API (generative search). Bing Webmaster Tools provides publisher APIs for submitting and monitoring site indexation.
