Systems and methods are provided for selecting content based on user interactions with content previously presented to a user but failing to generate a conversion. In operation, a content delivery system delivers a content package to a user terminal, where the content package includes a content designed to elicit a pre-defined response, such as a conversion. The user terminal then presents the content to a user and generates a journal of events occurring in response to the content package. The journal is then used to determine the proximity of the events in the journal to the pre-defined response. If the degree of proximity to the desired response is high, the user is likely prepared to complete the conversion and therefore a same or similar content can be selected for the user terminal. Otherwise, new content can be delivered to the user terminal.
