Abstract: Various approaches enable the detection of “viewed” content. For example, in digital advertising, when a user visits a web page, the web page can be rendered with an advertisement. Content is considered viewable when a user is given enough opportunity to view the content. Approaches described herein attempt to determine whether a user was given an opportunity to view such of such content by determining and using at least one of a viewability metric, performance activity level metric, snapshot of the content, or combination thereof.

Abstract: Various approaches allow for determining fraudulent activity as it relates to a publisher's reported web address and/or whether content has been viewed, or at least displayed with the opportunity of being viewed. When a user visits a web page, or other such page or application that displays content, the web page can be rendered with advertisements and/or other content. Approaches described herein can verify a publisher's reported web address as well as attempt to determine whether a user is given an opportunity to view such content by determining and utilizing a snapshot of the content.

Abstract: Systems, methods, and computer-readable media are disclosed for optimizing online content rendering. In one embodiment, an example method may include determining that a document indicative of a webpage includes a content component. The content component may be configured to include multi-object content. A multi-object content may be received. The multi-object content may include a plurality of content items. A Document Object Model (DOM) tree may be generated based at least in part on the document and at least a first content item of the plurality of content items. The DOM tree may be sent to a user device requesting the webpage. A subtree may be generated based at least in part on the DOM tree and a second content item of the plurality of content items. The subtree and a command to combine the subtree and the DOM tree may be sent to the user device.
