Abstract: An external traffic advertisement system is provided that generates advertisement sets based on analysis of visits to a web site that were referred by an external source. The advertisement system aggregates the referral information for each referral type. A referral type may be defined by one or more of keyword text derived from the query text of the referrals, landing page type, external source, product identifier, and so on. The advertisement system may, for each referral type, aggregate the total revenue from the visits of that referral type and may generate a count of the number of converting visits for that referral type. The advertisement system then identifies those referral types whose aggregated information satisfies an advertisement criterion and generates an advertisement set for each identified referral type with a keyword derived from keyword text and with a link based on the landing page type of the referral type.

Abstract: A method and system for generating advertisement sets for keywords automatically extracted from data feeds is provided. An advertisement system receives various data feeds. The advertisement system may on a periodic or an ad hoc basis request a feed server to provide the latest feed having feed items. Each feed item may include a title, a description, and a link to an associated web site. To generate an advertisement set, which includes an advertisement, a keyword, and a link to a landing page, the advertisement system extracts a keyword from a feed item, identifies a category for advertising using the extracted keyword, generates an advertisement (or “creative”) for advertising that category, and generates a landing page link associated with the category. The advertisement system then submits the advertisement set to an advertisement placement service for placement along with content that is somehow related to the keyword.
