    Abstract: The present invention provides systems and methods of searching web pages relevant to a specific topic based on quality of individual pages. The rank of a page for a keyword may be a combination of analytic rank and editorial rank. The analytic rank of a page may be calculated by combining intrinsic and extrinsic ranks. Intrinsic rank is a measure of relevancy of a page to a given keyword as claimed by an author of the page, while extrinsic rank is a measure of the relevancy of a page on a given keyword as indicated by other pages. The former may be obtained from an analysis of keyword matching in various parts of the page while the latter is obtained from context-sensitive connectivity analysis of the link structure of the entire Internet. Methods are described to solve the self-consistent equation satisfied by the page-weights and site-weights in a very efficient iterative way. The ranking mechanism for multi-word query is also described.
