JHU Licensed Accessibility Tools


Siteimprove is an automated website checking tool, with features that identify accessibility barriers for a website owner to review and correct.  JHU has a site license for this product. While automated website checking tools only catch about 30 to 40 percent of accessibility barriers, using Siteimprove is an important step in identifying and fixing web pages to achieve greater accessibility.  Manual accessibility checking also needs to be done to identify barriers that automated tools cannot. 

Siteimprove has other features that support link fixing, spelling and search engine optimization.  To get your site added to the Siteimprove scan, contact the Web Hosting team with your request.
