1. A method implemented by at least one data processing apparatus, the method comprising:
- determining historical click-through rates over a plurality of time periods for a first search result responsive to a query and for a second search result responsive to the query wherein the first and second search results refer to different respective web pages;
calculating click-fractions for one or more of the plurality of time periods based on the determined historical click-through rates of the first and second search results;
determining that a particular click-fraction of the calculated click-fractions in a first time period of the plurality of time periods exceeds a minimum change threshold;
obtaining search results responsive to the query during a second time period that chronologically follows the plurality of time periods;
adjusting a ranking of the first search result in the obtained search results during the second time period; and
wherein determining, calculating, obtaining and adjusting are performed by the at least one data processing apparatus.

Abstract
Apparatus, systems and methods for content ranking are disclosed. Historical click-through rates of first and second content items for a query are determined from an analysis of click logs and query logs. Temporal changes in the historical click-through rate of the first and second content items are identified. The rankings of the first and second content items are adjusted based on the temporal change.

21. A non-transitory machine-readable storage device having instructions stored thereon which, when executed by at least one data processing apparatus, cause the at least one data processing apparatus to perform operations comprising:
-
determining historical click-through rates over a plurality of time periods for a first search result responsive to a query and for a second search result responsive to the query wherein the first and second search results refer to different respective web pages; calculating click-fractions for one or more of the plurality of time periods based on the determined historical click-through rates of the first and second search results; determining that a particular click-fraction of the calculated click-fractions in a first time period of the plurality of time periods exceeds a minimum change threshold; obtaining search results responsive to the query during a second time period that chronologically follows the plurality of time periods; adjusting a ranking of the first search result in the obtained search results during the second time period. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
