A skull, or "death's head" as the pirates would call it, represents death. That's really all there is to it. It could be used to scare their enemies, as if to say "we will kill you." It could also symbolize the fact that pirates were not scared of death. They generally accepted that the pirate life is dangerous, as in the famous quote by Black Bart Roberts, "A short life and a merry one. This shall be my motto." Roberts crew sailed under two different flags; one that contained two skulls and one that contained a skeleton.
