Impact of search engine capturing attention (7)
I believe the answer is:
bearing
'impact' is the definition.
(thesaurus)
'search engine capturing attention' is the wordplay.
'search engine' becomes 'Bing' (Bing is a search engine).
'capturing' is an insertion indicator.
'attention' becomes 'ear' (having someone's ear is having their attention).
'bing' going around 'ear' is 'BEARING'.
'of' is the link.
(Other definitions for bearing that I've seen before include "north?" , "Position" , "Deportment" , "circular form?" , "Demeanour - direction" .)
