Abstract: An advertisement management method and system wherein a first set of phrases associated with a first party is received. A second set of phrases is determined, wherein each phrase in the second set is topically related to at least one phrase in the first set, and the second set includes at least one phrase from the first set. A third set of phrases is generated based on the second set. The second set includes at least one phrase that is not in the third set. The advertisement management method and system also receives social feed data, including first data posted on an online social network by a second party. A computer processor is used for automatically searching for matches between the first data and the third set of phrases. Responsive to a match identified by said searching, second data representing a social lead and including contact information of the second party is generated. In the advertisement management method and system, the first party is notified about the second data.
