The PageRank Citation Ranking: Bringing Order to…

PageRank asks how a search engine can estimate which web pages matter before it even sees a query. Read it to see how every page divides its authority among outgoing links, how repeated link-weight transfer settles into a global ranking, and why teleportation, incomplete crawls, and manipulation keep that score from being a synonym for truth.

Reading focus: Why a backlink from an important page contributes more than an ordinary backlink, while a source with many outgoing links gives each destination a smaller share. How repeated rank redistribution becomes the stationary distribution of an idealized random surfer that sometimes jumps to another page. Why PageRank complements text relevance rather than replacing it, and how rank sinks, dangling pages, crawl gaps, and adversarial links bound the result.
