Ballads almost always tell a folk-tale (or sometimes fairy-tale or supernatural story) -type story, which often (but not always) is tragic. In the majority of cases ballads were meant to be sung, so there is a definitely regular, rhythmic, song-like quality to them. Also, most ballads have repeated lines, usually at the ends of stanzas. "Sir Patrick Spens" has all of these features.
