Content owners (e.g., Website publishers) are provided with a simple mechanism to automatically summarize and display information (news, images, maps, etc.) related to inferred interests of a user or users visiting their Website. The targeting can driven by a variety of mechanisms including, for example, an automated contextual understanding of the content of the Web page, profile-based information derived from personal data supplied by, or inferred from actions by, the user visiting the Website, location-targeted information (e.g., inferred by the Website visitor's current geography), etc. “Related Content Units” may be used to help content owners render useful, related, content by allowing for a variety of targeting methods to gather related pieces of Internet content and present them integrated into an HTML iFrame or a JavaScript/XML feed which can be easily integrated by the Website publisher onto the Web pages of their Website.
