A method of improving a traffic pattern through web page nodes of a website is provided, including selecting web page nodes. The traffic pattern includes a sequence of nodes. Each node represents a first page having a link to a second page in a subsequent node. A visitor to a node prior to a conversion node either navigates to a subsequent node or fails to progress to a subsequent node. The method also includes, for each web page, identifying display elements on the web page node that are associated with a decreased probability that the user progresses through the traffic pattern to a subsequent web page node in the predetermined traffic pattern, determining a metric representing an impact on a conversion attributable to the display elements, ranking the plurality of web page nodes based on the metrics for each web page node.
