More CEOs are making themselves visible on social media.

A study from PR firm Weber Shandwick shows that the “online sociability” of CEOs for the world’s largest companies has shot up to 66 percent today from 36 percent in 2010.

Chief executives were consider “social” if they did one of the following things: engage on the company website, write a public-facing blog, have a public and verifiable social network profile, or appear in a video on the company YouTube channel.

Speaking of online video, an increasing number of those CEOs are using the medium, more than doubling to 40 percent today from 18 percent in 2010.

Leslie Gaines-Ross , Weber Shandwick's chief reputation strategist, said in a press release:

"By increasing their communications online, CEOs are showing they are listening to customers, are curious how their products are being received, care about attracting the best talent, understand the need to better humanize themselves and are more in-tune with where their stakeholders are."

The release from Weber Shandwick included this infographic, “Socializing Your CEO,” which breaks down the information even further:
