Abstract: In some embodiments, a non-transitory processor-readable medium stores code representing instructions to cause a processor to receive a user defined advertisement rule associated with a set of products listed within an inventory database. The user defined advertisement rule has at least one dynamic field associated with a field within the inventory database including a product title field, a brand name field, a website address field, a description field, etc. The code also represents instructions to cause the processor to resolve the at least one dynamic field for each product using a datum stored within the field to define a different advertisement for each product. The code further represents instructions to cause the processor to provide the different advertisement for each product to a search engine such that each advertisement can be displayed by the search engine in response to one or more search requests at the search engine.
