1. A method comprising: generating, by one or more server devices, a measure indicating a probability that links associated with particular feature data will be selected, the particular feature data identifying one or more link features associated with the links, wherein generating the measure comprises: identifying link selection data for a plurality of documents collectively having corresponding links, of the links associated with the particular feature data, wherein each of the plurality of documents each has a corresponding link of the corresponding links, wherein the corresponding links collectively link to a plurality of target documents and each of the corresponding links is to a corresponding one of the plurality of target documents, the link selection data indicating: a quantity of selections of the corresponding links of the plurality of documents, the selections each being based on a respective one of a plurality of user devices accessing a respective one of the documents and selecting the corresponding link of the respective one of the documents of the plurality of documents, and generating, based on the link selection data, the measure indicating the probability that links associated with the particular feature data will be selected; after generating the measure: generating, by one or more of the server devices, a rank for a particular document, wherein generating the rank comprises: determining that a particular link to the particular document is associated with the particular feature data, determining a weight of the particular link based on the measure, wherein determining the weight based on the measure is based on determining that the particular link is associated with the particular feature data, and generating the rank for the particular document based on the weight for the particular link, and based on additional weights for additional links to the particular document; identifying, by one or more of the server devices, documents associated with a search query, the documents, associated with the search query, including the particular document; and providing, by the one or more server devices, information associated with the particular document based on: the search query, and the generated rank for the particular document.
