Half of you have no idea how much of your info is public on Facebook

Want to master the CMO role? Join us for GrowthBeat Summit on June 1-2 in Boston, where we'll discuss how to merge creativity with technology to drive growth. Space is limited and we're limiting attendance to CMOs and top marketing execs. Request your personal invitation here!

In spite of recent concerns about privacy and surveillance on social media, most of us are extremely lax about our public/private boundaries on the biggest network of them all: Facebook.

A third of us haven’t checked our privacy settings in a year or longer — in spite of the fact that Facebook changes those settings and policies quite frequently.

And we’re giving away our information to companies far more than we realize. Sixty-one percent of us have no idea how many companies have the keys to our Facebook profiles via app permissions and Facebook logins.

Don’t even get us started on passwords.
