Abstract: A system 100 and method 102 for evaluating and correcting websites includes an assessment module 114 to parse and analyze the website as a function of a ruleset of design guidelines. A list of automatic correction items, semi-automated assisted correction items, and manual correction items is reported by a reporting module 116. The listed items are automatically, semi-automatically, or manually corrected by or through a correcting module 118. The system 100 and method 200 provide an internet based software tool to enable website providers to diagnose, evaluate, report, and retrofit code violations existing in websites.
