Abstract: In accordance with an embodiment, described herein is a system and method of using attribution tracking for off-platform content promotion, for use in media content or other computing environments. A media campaign can be associated with a promoted content link (e.g., a URL) for use on a publisher web site. When the promoted content link is selected, for example by a user of a client media device, the user/device can be redirected to the media content environment. Client activity data can be logged to provide one or more campaign, content promoter, artist, date, user identification, or other data, which can be recorded as a promotion event. In response to the user/device performing additional downstream actions with regard to the promoted content, downstream events can be generated, and data pipelines used in combination with attribution windows, to correlate attribution of the downstream actions with particular media campaigns or content promoters.
