• identifying at least one content item accessed by the user and logging a start time and/or duration of the user access to the content item;
• store the logged user interaction in the data store in association with the identified user;
• analyze the stored interaction data to form behavior data associated with the identified user;
• store the behavior data in the data store in association with the identified user:
• identify, based on the stored behavior data, at least one keyword and/or category to identify subject matter apparently of interest to the identified user;
• analyze the stored behavior data of the identified user to form an engagement score relative to the at least one keyword and/or category;
