Although the article from webcredible is titled “7 tips for designing for older users“, the strategies are great for plain old usability and accessibility. Here is a summary with some comments.
- Make obvious what’s clickable and what’s not. (Please don’t mess with the underlines!)
- Use radio buttons rather than dropdown menus. (Unless you have over, say, 8 options.)
- Stay in one window.
- Implement the shallowest possible information hierarchy. (And forget 3 or 4-level cascading menus; they are also difficult to navigation with our without a mouse.)
- Include a site map and link to it from every page. (Also good for SEO.)
- Keep your language simple.
- Appear trustworthy.
