The ordering of this list is not by priority or value of an item. For all intents and purposes, every item in this list has equal value.
Please keep in mind that there may be other criteria added, depending on the particular circumstances.
This list is not a critique of how we design or whose site looks prettiest. The focus IS the end user, the viewer, and the client. The purpose is to review sites, find errors and flaws; figure out what works; and point them out. The goal is to deliver a better experience for the viewer, and accomplish the goals of the client.
