Damaged by popular success? (3)
I believe the answer is:
hit
'success?' is the definition.
(hit is a kind of success)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hit that I've seen before include "Of a play, a smashing success" , "Successful record/film" , "Thump" , "Popular record" , "Visit to website" .)
