A method and system for providing advanced notice of cost to access web content. During transmission of web content over a communication path between a content server and a client station, an intermediation system adds into the web content, in conjunction with a hyperlink to web content, an indication of cost to access the referenced web content. The indication of cost will then be presented to a user when the web content is presented to the user, thereby giving the user an advanced notice of the cost to access the referenced content.
