Using resource load times in ranking search results

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for using resource load times in ranking search results. In one aspect, a method includes receiving a search query from a particular user device; receiving, for each of a plurality of resources responsive to the search query, a respective first score; accessing load time data that specifies, for each of the plurality of resources, a load time measure for the resource; and adjusting the first score for each of the plurality of resources based on the load time measure for the resource to generate a second score for each of the plurality of resources.

1. A method performed by data processing apparatus, the method comprising:
receiving a search query from a particular user device; identifying one or more attributes of the particular user device; receiving, for each of a plurality of resources responsive to the search query, a respective first score; accessing load time data that specifies, for each of the plurality of resources, a load time measure for the resource, wherein the load time measure for the resource is a statistical measure of a sample of load times for the resource compiled using only load times from user devices sharing at least one of the one or more attributes with the particular user device; generating a respective second score for each of the plurality of resources, wherein generating the respective second score for each of the plurality of resources comprises adjusting the first score for the resource based on the load time measure for the resource to generate the second score for the resource, comprising, for a first resource of the plurality of resources:
determining that the load time measure for the first resource of the plurality of resources is in a percentile that exceeds a first percentile of load times in a sample of collected load times for resources in a resource index, andin response to determining that the load time measure for the first resource is in a percentile that exceeds the first percentile, adjusting the first score for the first resource by applying a first multiplier factor to the first score; and providing a search results page including search results to the particular user device, wherein each search result corresponds to a respective one of the resources, and wherein the search results are ordered based on the second scores of the resources corresponding to the search results.
