Methods and systems for providing advertising content over the Internet through a hierarchical content-specific node structure and pricing advertising delivery over each node independently. Independent delivery and pricing allows an advertiser to pay more for advertisements delivered to a narrowly targeted audience likely to be interested in the goods or services offered by the advertising entity and to pay less for advertisements directed at a more general audience who may or may not have an interest in the goods or services offered. The less content specific the node is, the less targeted the advertisement will be, and therefore, the less valuable the advertisement will be to the advertising entity. Targeted advertising to multiple levels of content specific nodes is enabled.
