  • Method and system for associating an advertisement with a web page
    Patent number: 8676781
    Abstract: A method and system for associating an advertisement with a web page are disclosed. Web pages associated with potential queries may be identified using a search engine. A mapping operation may be performed to obtain a map of the web pages as a function of the potential queries. A reverse mapping operation may be performed to obtain a grouping of potential queries as a function of one of the web pages. An active query may be selected from the grouping of potential queries to provide to an advertising service to associate an advertisement with the web page.

  • Strategies for determining the value of advertisements using randomized performance estimates
    Patent number: 8571930
    Abstract: Strategies are described for conducting an advertising campaign using a cost-per-transaction (CPT) pricing model. In this model, the advertiser is charged when an end-user takes some express action in response to viewing the advertisement, such as by clicking on the advertisement, purchasing the advertised asset, performing a registration procedure, and so forth. Various solutions allow for the computation of the expected value of a CPT advertisement when there is a scarcity of data pertaining to the actual performance of the CPT advertisement.

  • Determining a backup server for a session based on a deterministic mechanism and the session's key value
    Patent number: 8090829
    Abstract: A mechanism is disclosed for determining, based on a deterministic mechanism and a session's key value, a backup server for the session. In one embodiment, each session has a different key value, and each key value can be processed through the deterministic mechanism to give rise to a separate ordering of a result value set. Each server of a plurality of servers is associated with a different one of the set's values. A request pertaining to a particular session is received. The request indicates the particular session's key value. The deterministic mechanism can generate result values, in a particular order to which the session's key value gives rise, until a result value associated with a currently operational server is generated. The request is sent to that server if the request's primary server is not currently operational. A pseudo-random number generator seeded with the key value may generate the result values.
