Consistent Identification (3.2.4 – AA)

Plain Language Recommendations

Components that have the same functionality within a set of web pages must be identified consistently.


  1. A submit “search” button on one Web page and a “find” button on another Web page both have a field to enter a term and list topics in the Web site related to the term submitted. In this case, the buttons have the same functionality but are NOT labelled consistently.
