What does Facebook know about you?


Yesterday we talked about the dangers of sharing too much information online and how that could lead to identity theft. Today we will look at the information Facebook knows about us and what is available to advertisers and the world through Facebook Graph Search.

The website daylandoes.com preformed an analysis of the different types of data collected and stored by Facebook.

The first set of data is what you personally provide Facebook about your life:

Facebook records not just facts but also all the interactions and activities you have done through the website including:

• Videos you’ve watched
• Comments you’ve liked
• Websites you’ve visited
• Articles and websites you’ve commented on
• Surveys you’ve filled out

All of this information is available to advertisers and depending on your permissions, everyone through the new Facebook Graph Search tool.
