The invention relates to a method, system and computer program for management of paid advertisements displayed in response to a search query entered into a search engine. A vendor's inventory is discovered by reading from an inventory database. Search terms are determined for item categories in the inventory database, reading from fields of the inventory database. A user can specify additional or replacement search terms to be associated with a particular item. Advertisement sets are then created for items which are currently available or “in stock,” each set containing an advertisement corresponding to an item, the associated search terms, and a landing page identifier. The landing page displays search results from the vendor's inventory database, relating to the corresponding item category for that advertisement.
