Systems and methods to provide online presence management are provided. A presence message is received from a browser associated with a user. One or more channels indicated by the presence message are determined, each channel being associated with an activity of the user. A presence state for each of the one or more channels are then determined, and a presence storage may be updated. Presence information comprising the presence state for the user may be provided to browsers of subscribers who subscribed to the same one or more channels. The presence information may be provided without an explicit request from the browsers.
