  • Patent number: 9031861
    Abstract: Methods, systems, and computer program products are provided for measuring effectiveness of content items included in a campaign. One example method includes providing a corpus of campaigns, where a campaign defines parameters for presentation that specify circumstances under which content items are presented to users in response to requests. The corpus is filtered by identifying one or more candidate campaigns, where each of the identified candidate campaigns is associated with a geographic region and includes one or more constraints that permit pausing distribution of content items without compromising campaign goals. For each candidate campaign, one or more experimental geographic locations included in the geographic region are determined that are substantially representative of the region. Presentation of at least one of the content items is paused for a time period, and content item effectiveness is measured by comparing resource conversions for experimental and control geographic locations.

  • Patent number: 8910195
    Abstract: The present disclosure provides systems and methods for enhancing audience measurement data. Offline and online audience measurement data may be compared and correlated to improve the quality of each data and source set. Positive correlations between the offline and online data sets related to a particular event may indicate demographic traits that are likely true, such that outliers may be removed from the set or considered at a reduced weight. Negative correlations may indicate that demographic information within a source set, such as the online measurement data, may be false or suspect.

  • Publication number: 20140214535
    Abstract: This specification describes technologies relating to selection and display of content items based in part on sequencing information. In general, one aspect of the subject matter described in this specification can be embodied in methods that include receiving a request for content and a user identifier. The methods may further include identifying a sequence of content items in a browsing history corresponding to the user identifier, where the content items in the sequence are members of a set of content items. The methods may further include retrieving an estimate of a conditional probability of conversion for a first content item from the set, where the first content item is presented after the identified sequence. The methods may further include determining a bid for an impression in the requested content based in part on the estimate of the conditional probability of conversion and transmitting the bid.

  • Patent number: 8707442
    Abstract: A dynamic URLs construction system includes a publisher server and one content accessor server. The publisher server has a content URL access module, a content access module and a content database for storing media content and providing content URL accessing instructions and media content to a content accessor server. Media content provided by a publisher is accessed using dynamic URLs. A content accessor server includes at least one dynamic URL generation module and one content retrieval module. The content accessor server receives a content ID and a template URL containing instruction for constructing the corresponding dynamic URL from the publisher server. The dynamic URL generation module parses the template URL instructions, obtains an access key associated with the dynamic URL and constructs the dynamic URL using the access key and the content ID. The content retrieval module retrieves the content referenced by the dynamic URL.

  • Patent number: 8548851
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing conversion path performance measures and reports. In one aspect, user interaction data are obtained, were the user interaction data specify user interactions for a plurality of conversions. User interactions that are associated with each conversion are selected from the user interaction data, where the associated user interactions for each conversion are user interactions with a converting user during the conversion cycle for the conversion. Using the user interaction data for the selected user interactions, a quantity of user interactions that are associated with each conversion and occurred during the conversion cycle for the conversion are determined. In turn, conversion path performance measures are computed and reports specifying the conversion path performance measures are generated.

  • Patent number: 8521774
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dynamically generating and configuring pre-aggregated datasets optimized for responding to particular types of data requests made against a large sub-optimal multidimensional dataset are disclosed. A dynamic aggregator monitors the query types and response latencies associated with queries made against the large multidimensional dataset. The dynamic aggregator defines pre-aggregated datasets based on the types of queries received from users and calculates a respective benefit score for each pre-aggregated dataset. The benefit score of each pre-aggregated dataset can be based on the recorded latencies and query count for the pre-aggregated dataset. The dynamic aggregator can decide whether to generate and/or maintain particular pre-aggregated datasets based on the current values of the benefit scores associated with the particular pre-aggregated datasets.

  • Publication number: 20110307320
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing content performance measures and reports. In one aspect, a method receives a request for a user interaction report that specifies measures of user interactions with content items for a reporting period. Initial user interaction data representing user interactions with content items over the reporting period are obtained, where the user interaction data is associated with unique identifiers that each represents a user device with which user interactions are associated. For each of the unique identifiers an initialization time that specifies a time at which the unique identifier was associated with a user device is determined.
