CEO’s of NASDAQ 100 companies are far less active on social networks than one might expect. At least that is what the recent study by influence marketing software specialists Augure shows; highlighting that only 30% of executive directors within NASDAQ 100 companies are present and active on social networks, compared to the 70% that have no presence on online platforms.

The Top influencers in online media include the CEOs of Apple, Tesla Motors, Yahoo!, Facebook and Dell. The influence classification corresponds to the data registered by the Augure Influencers tool over the last year (from November 2012).

The top position is held by Tim Cook, CEO of Apple and one of the world’s most influential CEO’s. Despite being recently named the world’s most valuable company by Forbes, and the largest in stock value by PwC , the Apple brand has no official social network presence whatsoever.

Highlighting the impact and influence of Tim Cook in Social Media, the study shows that in the last year he registered over 248,000 hits on online media and his official Twitter account, @Tim_Cook and received over 86 thousand mentions. By comparison, Robert Kotick, the tenth most influential CEO of NASDAQ 100 in 2013, received 434 hits on online media and only 13 mentions on Twitter.

The second and third positions are taken by entrepreneur Elon Musk, CEO of Tesla Motors, and Marissa Mayer, CEO of Yahoo!, the only woman present in this ranking. Larry Page, Google’s CEO did not make it into the Top 10 influencers; unaspiringly the only active and official social media profile he maintains is on Google+.

Despite the low participation of NASDAQ CEOs in social networks, there are preferences among the different platforms. The most popular is LinkedIn, with 23% of executives present in this professional social network. In second place is Twitter, with 11%, followed by Google+ and Facebook, with 8% and 5%, respectively.

Facebook, the social network with over a billion global users, whose CEO is ranked forth by influence, is not as popular among NASDAQ company leaders. Only Marissa Mayer and Elon Musk have an official Facebook page while Philippe Dauman of Viacom and Shantanu Narayen of Adobe have personal profiles on the platform.
