The Activity timeline serves as a running list of interactions individuals are having with you. Activity includes all information found in the Activity tab under Criteria in the Audience tool.
Activity appears timestamped in each profile and provides you a running timeline of every touchpoint a person has had with you.
You also have the ability to filter on Activity Type within a profile to pinpoint specific touchpoint you've had with that individual.
Click on "All Types" to filter out the type of interaction for the profile:
Activity is then calculated to a Crowdskout Score giving you an even better idea of how engaged each individual is with you. Crowdskout Scores are located in the Scores tab in any profile.
