Systems and methods that improve search rankings for a search query by
using data associated with queries related to the search query are
described. In one aspect, a search query is received, a related query
related to the search query is determined, an article (such as a web
page) associated with the search query is determined, and a ranking score
for the article based at least in part on data associated with the
related query is determined. Several algorithms and types of data
associated with related queries useful in carrying out such systems and
methods are described.
