A retrospective look at website accessibility over time

Evaluation of web accessibility in China: changes from 2009 to 2013

“…Another study found that the average accessibility level of social work education websites increased significantly from 2003 to 2008 [14]. On the other hand, some other longitudinal evaluation studies found web accessibility to be less accessible as webpage complexity increases [11,12,15].…”

“…Given the fact that many websites fail to achieve web accessibility, a phenomenon that has been widely revealed by many researchers [1][2][3][4][5][6][7][8][9][10][11][12], there is likelihood that Chinese websites may have major accessibility problems; however, there is a lack of research into the accessibility of Chinese websites. This paper thus aims to provide an overview of the status of web accessibility in China according to two evaluations, one in 2009 and the other in 2013.…”

Web accessibility guidelines

“…In addition, while work has been undertaken at the intersection of Web accessibility and Web evolution there has been little work of the kind undertaken here and there are no sources which specifically would enable us to support our anecdotal assertions. Studies to understand the extent of accessibility and assist in addressing these failings have been undertaken [24], but, these studies have only considered how changes in Web design have affected accessibility over time, and suggested possible solutions to address these problems without a full scale accessibility re-evaluation.…”
