Abstract: Contextualization services deliver a contextualized toolbar for display on a page. A client agent may contextualize content a page being loaded or displayed to identify and send contextual data to the contextualization service of the server. The page may be designed, configured or constructed for placement of a toolbar on the page, such as a footer bar on the page. The contextualization service may use the contextual data to select a campaign from a plurality of campaigns to deliver a contextual toolbar for the page. Based on the selected campaign, the contextualization service may send a toolbar or configuration for a toolbar to the agent for display on the page. Instead of having a toolbar predetermined or fixed prior to the display of the page, the present solution dynamically contextualizes a toolbar at the point of loading or displaying the page and the contextualization is based on the content of the page being loaded/displayed.
