Use banner headlines to create excitement (6)
I believe the answer is:
splash
'excitement' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for splash that I've seen before include "Fall in irregular drops" , "Drop" , "Lead newspaper story" , "Watery sound" , "Sound of an object hitting liquid" .)
