I need to be able to answer these questions at a glance, correctly and unambiguously, with very little effort. If it’s not clear to me what I’m looking at in the first few seconds, interpreting everything else on the page is harder, and the chances are greater that I’ll misinterpret something and get frustrated. But if I do “get it,” I’m much more likely to correctly interpret everything I see on the page, which greatly improves my chances of having a satisfying, successful experience.
