The verb is more interesting than the noun for a learner, because it has a figurative sense that is very common in academic and business writing: to signpost is to tell the reader in advance where the argument is going. Good signposting means a piece of writing tells you what is coming — firstly, this section will, in summary. That skill has a name because it is teachable, and it is one of the things most often marked down in a first essay.
