Abstract: The system and methods of the present technology are configured to determine the in-view status of advertising from within an iframe configured to display the advertising, without relying on code operating the hosted web page bearing the advertising. The system and methods use a plug-in or applet resident in a client device and the application programming interface (API) of the client device, in combination, to determine if the advertising is in-view or not, by superimposing one or more invisible animation frames over a screen area occupied by the advertising. Each superimposed invisible animation frame has access to data on view-ability. The application programming interface (API) by examining the frame rate progression of the one or more invisible animation frames determines if the advertising on which the invisible animation frames are superimposed is in fact in-view and then reports this information to a server configured to collect this data.
