Do you mean the like button simply being present on pages or actual clicking of the like button? My understanding is clicking on the like button is pointless unless you're actually signed in to facebook.
- fixermark 9y agoThe like button actually being present means that your client makes a request to FB to fetch the relevant image resources and JS to display the button. When that occurs, FB has some limited ability to get information on your browsing habits based on what that like-button JS is allowed to see of your current session (which given browser fingerprinting techniques, can be enough to unify your behavior with high probability across multiple disparate "blips" of signal).
- kerng 9y agoThe loading of the Like button will give Facebook information about your user agent - it's like a tracking pixel. It's been shown that user agent information together with IP pretty much uniquely identify a user. You dont have to click anything
