Some factors listed here represent an initial expense but a long-term savings.
Various factors can affect the cost of making Web sites accessible. For new sites that are more complex in design, accessibility again may add relatively little to the cost compared to the overall cost of development, and may create some longer-term savings in site maintenance and updating. Existing Web sites using valid W3C technologies may require relatively little expense to retrofit. Therefore factors listed here are presented as questions for consideration. Impact on Web site development process Development of more consistent site appearance and use of technologies May prompt a move towards template-based pages on site, which involves an initial investment, but subsequently reduced development time and maintenance costs, as well as greater usability due to consistency of design across the site.
