It has no official meaning. It generally means pages that expect to have the most traffic on a wiki, like the main page or the primary page for the topic, like the The Expanse page for the the 'The Expanse'' series of books/TV show.

High traffic pages tend to be targets for vandalism, because the vandal expects their vandalism to be seen by more people.
