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.
