Abstract: A system for transmitting electronic content over a computer network is provided. In one technique, client devices that visit a website send, to a content delivery service, interaction data that indicates that the client devices interacted with the website. Later, a content provider of the website creates a content delivery campaign with the service or establishes (or renews) a retargeting segment for an existing campaign. The content delivery campaign indicates that certain content is to be delivered to entities who have interacted with the content provider, such as by visiting the website. The content delivery service uses the interaction data to identify candidate entities who satisfy targeting criteria of the retargeting segment. If a candidate entity does satisfy the targeting criteria, then the candidate entity is added to the retargeting segment, even though the candidate entity may not have interacted with the website after the retargeting segment was created or renewed.

Abstract: Technologies for identifying and recommending dimension values for a content delivery campaign are provided. Disclosed techniques include receiving, from a content provider, input that selects one or more entities. In response to receiving the input, a plurality of dimension values are identified from each of the one or more entities. Dimension values may represent attributes associated with entities. A set of dimension values for recommendation may be identified from the plurality of dimension values previously identified. The set of dimension values for recommendation may be presented to the content provider for the purpose of generating a content delivery campaign based upon the recommended set of dimension values.
