Abstract: Embodiments involve managing online content provided via data networks. For example, the computing system causes a web server to include, during a first time period and in a search results list generated by a search engine, an online advertisement having a webpage link for purchasing a product or service. The computing system determines, subsequent to the first time period, that the product or service's availability has been reduced and that an alternative product or service has a greater availability. The computing system identifies a modification for the online advertisement based on the reduced availability. The modification involves replacing the webpage link with an alternative webpage link for purchasing the alternative product or service. The computing system causes the web server to implement the modification by including, during a second time period and in a second search results list from the search engine, the online advertisement with the alternative webpage link.

Abstract: A method and system for availability based computer marketing optimization is presented. An advertiser maps product identifiers representing products and/or services for their respective business in a campaign management system. The product identifiers are mapped to keywords and/or advertisements in the campaign management system. Competitive bidding on the keywords determines placement of the advertisements in search engine results or websites accessed by an advertisement server, in some embodiments. Rules are implemented in a campaign management system to automatically determine modifications based on the availability of a particular product identifier representing a product or service. In some embodiments, the modifications are implemented at the search engine and/or advertisement server.
