Abstract: The system provides an automatically targeted network for text and graphical advertising based on cost-per-action bidded pricing, wherein actions comprise any of acquisitions, purchases, downloads, registrations, donations, clicks, and impressions. Contextual, search and behavioral relevance features are integrated to optimize ad selection for advertisers, who enter action objectives, associated bids, and creatives or catalog assets. The assets are automatically analyzed and stored, and ads are automatically constructed for catalog assets. When an ad request is received from a user terminal in regard to a publisher asset, e.g. a web page, the ad request is matched to a stored contextual analysis of at least a portion the publisher asset if available, and preferably to a profile associated with the user of the user terminal. The best advertisements are determined, based upon a predicted response, and are then served, i.e. displayed, at the user terminal, based upon available ad space.
