Look up and try salacious look (6)
I believe the answer is:
'look up' is the definition.
(look up online)
'try salacious look' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'salacious look' becomes 'ogle'.
'go'+'ogle'='GOOGLE'
'and' acts as a link.
(Other definitions for google that I've seen before include "Widely-used search engine for internet" , "Popular search engine for internet" , "Search online" .)
