Before people can navigate successfully, they have to orient themselves, to the space as a whole, and to their current location within it. Four principles support this. Make the purpose of the space clear, so people can quickly tell whether they're in the right place. Provide previews of content, so people can sample what's available before committing to explore further. Create context through consistent navigation and descriptive page titles. And establish visually prominent landmarks, global landmarks like a logo, header, and footer that appear everywhere, and local landmarks like a highlighted navigation link or page title that show a more specific location.
Orientation isn't a single principle: it's four different signals working together, and a space that gets three right can still leave people lost if the fourth is missing.
A, Make the purpose of the space clear. Vague navigation labels like "Explore" and "Discover" tell a first-time visitor nothing about the actual scope of what the university offers.
B, Provide previews of content. A bare list of department names gives her nothing to sample, no way to judge value before clicking deeper into any one of them.
C, Create context. A descriptive page title is one of the core ways a space creates context for where you are, without it, she has no confirmation of what page she's looking at.
D, Establish landmarks. A highlighted navigation link is a local landmark, it shows a more specific location within the space. Its absence means she can never tell which section she's currently in just by looking at the nav bar.
There's a reasonable case for point A being the fastest point of abandonment, it happens right at the door, before she's invested any effort, and vague purpose signals could cause her to leave before she even starts exploring. But there's also a case for landmarks compounding the most over a longer visit: missing landmarks don't stop her immediately, but they make every subsequent step slightly more disorienting, which could wear down patience gradually rather than all at once.Both readings are defensible, the point of this exercise isn't to land on one correct ranking, but to notice that these four signals fail differently. Some failures are acute and immediate; others are cumulative and only become a problem over a longer visit.
