What is Reciprocal Rank Fusion (RRF)?
Reciprocal Rank Fusion, or RRF, is a ranking method that combines results from multiple search systems by rewarding documents that rank well across more than one list. In AI search, RRF is useful because systems often blend keyword retrieval, vector retrieval, freshness, and other ranking signals before an LLM generates an answer. A page that performs reasonably well across several retrieval methods may beat a page that performs well in only one. For GEO and SEO teams, RRF reinforces the need for balanced optimization: exact language for important prompts, semantic depth, authority signals, structured content, and technical accessibility all work together.
