1. A method for using identifiers of selectable elements of network content that is stored using a hierarchical data structure to obtain analytics data for the network content when a presentation of the selectable elements changes overtime, the method comprising: electronically receiving, by a processing device, first analytics data indicating a selection of a selectable element of network content, wherein the first analytics data includes a first hierarchical position identifier corresponding to a location of the selectable element in a hierarchical data structure of the network content; electronically receiving, by the processing device, second analytics data, wherein the second analytics data was generated from a second selection of the selectable element of the network content, wherein the second analytics data includes a second hierarchical position Identifier, wherein at least some of the network content changed from a time at which the first analytics data was generated to a time at which the second analytics data was generated; identifying, by the processing device, a current selectable element of a current version of the network content from both the first hierarchical position identifier and the second hierarchical position identifier; matching, by the processing device, the current selectable element of the current version of the network content to both the first analytics data and the second analytics data based on identifying the current selectable element from the first hierarchical position identifier and the second hierarchical position identifier, wherein matching the current selectable element to both the first analytics data and the second analytics data comprises incrementally removing a portion of at least one of the first hierarchical position identifier, the second hierarchical position identifier, and a hierarchical position identifier from current data corresponding to the current selectable element until the first hierarchical position identifier, the second hierarchical position identifier, and the hierarchical position identifier from the current data match one another; and outputting, by the processing device, combined analytics data associated with the current selectable element based on matching the current selectable element to both the first analytics data and the second analytics data.
