A method and system for scaling navigation path weights among online content sources. A method may include determining a first probability of users traversing a first navigation path from a first to a second online content source, dependent upon a ratio of traversals of the first navigation path and traversals of all navigation paths to the second online content source. The method may also include determining a second probability of users traversing navigation paths from the first online content source to any of the online content sources, dependent upon a ratio of the plurality of online content sources to which navigation paths from the first online content source exist and a total number of the plurality of online content sources. The method may further include generating from the probabilities a scaling factor indicative of a strength of the first navigation path relative to other navigation paths among the online content sources.
