The song topped a list of 100 riffs put together by a panel of Djs, critics and record producers for BBC Radio 2 listeners to vote on.
Reacting to the news, a shocked Page, says, "I wanted a riff that really moved, that people would really get, and would bring a smile to their faces, but when I played it with the band, it really went into overdrive.
"There was this intent to have this riff and the movement of it, so it was menacing as well as quite sort of caressing."
Guns 'N' Roses' Sweet Child O' Mine land in second place, while AC DC's Back In Black takes the third spot. Deep Purple's Smoke On The Water and Derek And The Dominoes' Layla round out the top five.
