A
system and related techniques host and serve selective, orchestrated advertising campaigns and other content to users depending on contributing advertisers' campaign strategies as well as use interests, prior history or experiences. According to embodiments, users may navigate to a Web or other network site which contains or invokes ads or other media or content. When ad or other content is called, according to the invention in one regard a
user identifier may be checked, to determine whether the user has subscribed to or had a profile established with the orchestrated ad platform of the invention. If the user does have a
unique identifier associated with them, an ad engine may perform a lookup of the identifier against potential ad campaigns or delivery
modes, to deliver a more coherent or orchestrated
stream of ads or other media to the user. Those selected campaigns may include for instance immersive delivery
modes in which a number of ads related to an area of interest, such as cars and related services or foods and restaurants, may be delivered or streamed to the user's browser or other application at a comparatively
high frequency or intensity. The sequence of that content may in one regard be conditioned on the user's browsing or other history, including topics of interest as expressed for example in prior search activity, in explicit questionnaires, or in prior purchase or shopping activity, as well as other behavioral patterns such as averaged length of browsing sessions, or other parameters. Because the experience which the user receives is targeted or tailored in nature, and in addition presents a set or series of content which is selected to reflect a meaningful relationship or theme, the effectiveness of the advertising or other
content delivery campaign may be enhanced compared to undifferentiated delivery techniques.
