Abstract: Methods, systems, and apparatus, including computer program products, in which contextual bids for an auction are provided for advertisement requests for presentation of an advertisement in an identified context. Each contextual bid is based on an effectiveness measure associated with a corresponding advertisement and the identified context. Each corresponding advertisement can be served in a plurality of contexts, and the corresponding advertisement has a corresponding plurality of effectiveness measures, each effectiveness measure determined from evaluation results received from evaluations conducted in the plurality of contexts.

Abstract: Methods, systems, and apparatus, including computer program products, for measuring strengths of associations between branding content and branding content. In an aspect, branding content associations are collected from sessions of psychometric tools for branding content at client devices. Determined are orders of mention defining an order in which the branding content associations were input at each of the client devices, frequencies of mention for each of the branding content associations, and latencies of mention for each of the branding content associations. One or more of these metrics can be used to determine association strengths for each branding content association.

Abstract: At a server, during one or more first time periods, event data is received from a first client with respect to one or more events that occur at the first client. The event data is sent by the first client under control of a first application resident on a removable storage device. At the server, during one or more second time periods, event data is received from a second client with respect to one or more events that occur at the second client. The event data is sent by the second client under control of the first application resident on the removable storage device. The first and second time periods are non-overlapping.

Abstract: Methods, systems, and apparatus, including computer program products, in which evaluation versions of advertisements are generated and served in different contexts. Based on received evaluation results, engagement rates, brand linkage and advertisement effectiveness measures are generated for each of the different contexts and for an overall context.

Abstract: A system receives bids associated with placement of respective surveys. The system selects one or more of the surveys based on their respective bids and associates the selected one or more surveys with documents hosted at one or more servers.
