4.2 Provide additional navigational aids

Navigational aids provide additional and alternative ways to get around a site. Good for people who need to or who choose to.

Provide a Site Search:
- On every page, and ensure it is visible without scrolling
- Provide an advanced search on a separate page. Form should permit complex searches without knowledge of boolean logic, etc.
Provide a site map / contents list
Provide 'breadcrumb' navigation:
- Provides information about where the current page is in the hierarchy, and navigation to higher levels
Provide within page 'contents' navigation:
- Necessary on long pages
- 'Back to top' links if necessary
