Patent attributes
Methods, computer-readable media, and systems for placement attribute targeting are described. In one example, an advertiser can specify attributes of one or more web pages on which their advertisements can be displayed. Based on a page attribute of the web page that a user accesses, one or more advertisements can be transmitted to the user for display, where the advertisements are chosen such that the page attribute matches the attribute specified by the advertiser. In some implementations, a computer-implemented method includes determining an attribute of a web page to be displayed to a user at a location, selecting content corresponding to the determined web page attribute, and transmitting the selected content to the location for display as at least part of the web page.
