Methods and apparatus are provided to provide served ads to one or more clients based on dynamic-community information, ad-related information, service features, service activity, country of origin, and device-related information. Dynamic communities are formed based on a trigger, which may be a command, a request for information, a change in context, or an event notification. After receiving the trigger, a served ad may be piggybacked onto a response to the trigger. The served ad may include graphical, audio, textual, and/or other information. Additionally, served ads may be sent in response to ad requests. A served ad may be selected based on ad-screening rules and/or conflict resolution between advertisers competing to provide the selected ad. |
