Abstract
A method for creating a hidden text data index for ranking computerized query search results that includes generating a render tree based on a document object model (DOM) tree for a web page. The render tree includes nodes that correspond to text that will be visually displayed by a client device when executed. The method includes comparing nodes corresponding to text of the DOM tree with the nodes corresponding to text of the render tree to identify the nodes in the DOM tree that will not be visually displayed when executed by the client device. The method also includes creating a hidden text data index for the nodes corresponding to text of the DOM tree not in the render tree. The hidden text data index identifies nodes corresponding to text of the DOM tree as hidden that will not be visually displayed when executed by the client device.
