Signposting breaks up text and images into readable, easy-to-follow blocks or panels of information.
A kicker is a form of visual signpost that helps a reader assess an article before committing to reading the whole thing. It gives a small hint as to what is to come or helps identify the type of article they are about to read. It is usually only a word or two in length, maybe slightly longer.
Kickers might be boxed, placed in some shape such as a speech bubble or starburst, set in reversed type or in color.
