What is online interest-based advertising from Facebook, and how can I control whether I see online interest-based ads?
Online interest-based advertising means deciding which ads you might like to see based on your activity on websites and apps off of Facebook. Your activity on websites and apps off of Facebook that use Facebook's services and technologies can help us learn about which ads you might be interested in. You can see online interest-based ads from Facebook on Facebook, or on other websites and apps where we serve ads.
You can control whether you see online interest-based ads from Facebook in your settings. Keep in mind that if you choose not to see online interest-based ads from Facebook you’ll still see ads, but they may not be as relevant to you. If you turn on or off the ability to see online interest-based ads from Facebook, we'll apply your choice across all your devices and browsers. If you opt in on Facebook, but then later opt out on your device or with the Digital Advertising Alliance in the US, the Digital Advertising Alliance of Canada in Canada or the European Digital Advertising Alliance in Europe, we'll apply your choice to opt out only on the device or browser where you made the choice.
