1. A computer-implemented method comprising: determining that, among a set of search results that include multiple search results and are each identified as at least potentially relevant by a search engine in response to a search query submitted to the search engine and based on content of a document associated with each search result, one single search result is classified by the search engine as very relevant to the search query based on at least one parameter, calculated by the search engine, that determines relevancy; and in response to determining that, among the set of search results that include multiple search results and that are each identified as at least potentially relevant by the search engine, based on the content of the document associated with each search result and in response to the search query submitted to the search engine, one single search result is classified by the search engine as very relevant to the search query, automatically outputting a web page that is referenced by the one single, search result that is classified by the search engine as very relevant to the search query, rather than providing a search results page that references a subset of the set of search results that are each identified as at least potentially relevant based on the content of the document associated with each search result and in response to the search query, the one single search result is classified as very relevant based on a relevance score for the result relative to relevance scores for other search results in a ranked list of search results; wherein automatically outputting the web page that is references by the one single, search result includes providing instructions that cause a client device to provide the web page to the user for display directly after the client device displays a page for the user to submit a search query to the search engine.

The method of claim 1 , comprising classifying the one single search result as very relevant to the search query based on a parameter that is an observed historical click through rate associated with the one single search result, the one single search result being one of the one or more search results that are each classified as at least potentially relevant to the search query.
