Copilot retrieves sources from Bing's search index. The model then selects which sources to cite. This creates two layers of ranking: Bing indexing and Copilot selection.

Microsoft's Copilot documentation is at https://learn.microsoft.com/en-us/copilot/overview. The system uses GPT-4 combined with Bing search.

Key Ranking Factors

Bing search ranking. Copilot uses Bing's index. High Bing rankings improve Copilot citation probability. Focus on Bing SEO fundamentals.

Source authority. Copilot favors established domains. Government, educational, and major news sources are preferred. Niche sites need strong topical authority.

Content freshness. Recent content gets priority for time-sensitive queries. Bing's freshness signals carry over to Copilot.

Query relevance. Copilot evaluates how well a source answers the specific query. Direct answers are more likely to be cited than tangential content.

Structured data. Pages with Schema.org markup are easier for Copilot to parse. This increases citation probability.
