Abstract: Methods and systems for facilitating generation of electronic advertising messages based on model web pages. A visual content request is received that identifies a model web page. Source code is retrieved that includes patterns that can be matched to identify visual features of the model web page. Visual content information is provided to an advertising message generation service to construct advertising messages that include at least a portion of the identified visual features. Constructed advertising messages are received, including at least one modified advertising message that incorporates a user-selected image extracted from the model web page. The identified visual features of the model web page can include text format, text color, background color, images, and video sequences.

Abstract: A facility for analyzing electronic advertising is described. The facility determines that a particular client device has been used to activate a first advertising message for a particular cause. In response, the facility identifies a second advertising message for that cause that was presented on the same client device at a time before the first advertising message was activated. In response, the facility determines that the activation of the first advertising message is at least partly attributable to the presentation of the second advertising message.
