Try to keep navigation link labels under 20 characters to avoid text wrapping. Keep in mind, menu items must be short enough to scan, but long enough to be clear.
Keep all labels similar in length, context, and type. If using nouns to title pages and links, use nouns in the navigation. If using verbs, use verbs for all link titles and pages. Likewise, make sure they are similar character lengths.
Tell users exactly where they are going and what they can expect.
Link titles should reflect page titles
To help users with information scent, make sure page titles match navigation links.
Use sentence case in navigation links.
