Stick publicity notice on this spot (6)
I believe the answer is:
adhere
'stick' is the definition.
(to adhere to something is to stick to it)
'publicity notice on this spot' is the wordplay.
'publicity notice' becomes 'ad' (advertisement).
'on this spot' becomes 'here' (I've seen this in another clue).
'ad'+'here'='ADHERE'
(Other definitions for adhere that I've seen before include "Stick to, cling" , "Stick like a stamp" , "Stick to as by suction" , "paste" , "Stay attached" .)
