1. A computer-implemented method, comprising: identifying, by a computing system, a particular search result that was determined, along with a plurality of first search results, to be responsive to a first query, wherein the particular search result corresponds to a particular result document and each first search result of the first search results corresponds to a respective first result document, wherein the particular result document is a particular web page and the particular search result is configured to provide navigation to the particular web page upon user selection of the particular search result from among a presentation of multiple search results; identifying, by the computing system, a second result document that is associated with the particular result document due to the second result document including content that identifies an object that is also identified by content included in the particular result document, wherein a second search result corresponds to the second result document; identifying, by the computing system, second relevance data that indicates a popularity of the second search result as a selection by a second population of users as a result for a second query that is identical to the first query or similar to the first query; and determining, by the computing system, a score for the particular search result based on (i) first relevance data that indicates a popularity of the particular search result as a selection by a first population of users as a result for the first query, and (ii) the second relevance data that indicates the popularity of the second search result as the selection by the second population of users as the result for the second query.

The computer-implemented method of claim 1 , wherein: the particular search result and the plurality of first search results were determined to be responsive to the first query as a result of a search by a first search engine of a first corpus of result documents; and the second search result was determined to be responsive to the second query as a result of a search by a second search engine that is different than the first search engine of a second corpus of result documents that is different than the first corpus of result documents.
