Web content accessibility guidelines such as JIS X 8341-3 and WCAG 2.0 working draft require the separation of content structure from presentation. In (X)HTML, content structure is marked up with heading elements, list elements, etc. Objective evaluation of how content-presentation separation improves accessibility is needed to force Web authors to follow these accessibility guidelines. The current paper measures how usability and accessibility is improved when content is marked up with heading elements. The experiment was carried out firstly with four sighted persons and found that structured Web pages improve task completion time by 50% to 90%. The second experiment was carried out with one visually impaired and found that structured Web pages improve task completion time by 30% to 70%.
