Stick notice in this location (6)
I believe the answer is:
adhere
'stick' is the definition.
(to adhere to something is to stick to it)
'notice in this location' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'in this location' becomes 'here' (I've seen this in another clue).
'ad'+'here'='ADHERE'
(Other definitions for adhere that I've seen before include "Header (anag)" , "Stick to or continue faithful" , "'Stick to, a play say (6)'" , "Stick or cleave to" , "Agree" .)
