The survey measured a number of qualities, including likability, public awareness and influence, reported Ace Showbiz.
Nielsen looked at celebrities who made commercials during the first quarter of the year and ranked them based on N-Score which took into account the aforementioned qualities.
Neeson, 62, alongside Pierce Brosnan got the same score of 94. Despite the matching score, Nesson was put at the top of the list as he was said to have greater influence in getting the products sold.
Neeson appeared in a "Clash of Clans" commercial for Supercell Games, while Brosnan promoted Kia Motors. The survey company said that Neeson was viewed positively by 78 per cent of Americans who knew him.
