Abstract: Techniques are described for effecting data aggregation in a network. Event notifications are received from a plurality of content sites on the network. Each event notification indicates occurrence of an event associated with a corresponding one of the content sites. Each event corresponds to a change to content associated with the corresponding content site. In response to each event notification, event metadata are generated. The event metadata include a time stamp for the event and change data corresponding to the change to the content. The event metadata are indexed in a plurality of databases with reference to a plurality of index metrics including the time stamp. The indexing of the event metadata for each event occurs within days, hours, or even minutes of receipt of the corresponding event notification thereby enabling retrieving of the changes to the content from the plurality of databases using any of the index metrics in near real time.

Abstract: Methods and apparatus are described for presenting advertising content on a user device in conjunction with requested content. The advertising content is selected with reference to advertising targeting information. The advertising targeting information is generated by processing the URL associated with the request for the requested content generated by the user device.

Abstract: Methods and apparatus are described for selecting advertising keywords for advertising campaigns. A set of keywords is identified from a dynamic data set. The dynamic data is generated from at least one data source which is updated via the Internet substantially in real time. Each keyword in the set of keywords is characterized in the dynamic data set by a current relevancy measure not yet apparent from conventional search engine databases. A subset of the keywords is selected for use in the advertising campaigns with reference to at least one current market condition relating to each selected keyword. Advertising campaigns are initiated for each of the selected keywords.
