Xpath related and other techniques for use in native advertisement placement

Abstract

Techniques are provided that include obtaining a Document Object Model of an HTML document, such as a web page of a publisher. Elements of the Document object model may be identified that are associated with native advertisement placement candidate containers. Based at least in part on analysis associated with the Document Object Model, and utilizing at least some of the identified elements, one or more native advertisement placement candidate containers may be determined. With some techniques, the analysis includes identifying a deepest set of nodes in the Document Object Model, corresponding to a particular tag sequence, whose cardinality is no less than a cardinality of a set of nodes in the Document Object Model, corresponding to a particular tag sequence, corresponding to the identified elements. Some techniques may utilize XPaths in the analysis.
