Can you find out who views your facebook?
The Facebook terms do not allow this to happen (for anything, including, but not limited to, pictures, videos, and the profile page itself). ie. Facebook does not allow users to track profile views or see statistics on how often a particular piece of content has been viewed and by whom. There have been several applications that have claimed to do this in the past, but they either didn't work or were removed by facebook for violating its privacy terms. Third party developers, however, may offer applications that provide some of this functionality, subject to the following terms: 1. Applications cannot track profile views for users who simply visit another person's profile. Facebook has made this technically impossible. 2. In order to be tracked by an application, you must explicitly agree to allow the application to access your information. 3. Adding an application that provides this functionality is purely optional. If you do not want to participate, please do not add the application to your account. Unlike myspace, Facebook's philosphy is to let users view what they want without others knowing what they viewed. So you can check out that cute guy/girl with no worries about them finding out, but you will not be able to find out who has been viewing yours.
How does Facebook Pixel work?
Are you familiar with Google Analytics? with it, you can track the number of times a specific page is being viewed. This also works for images - with Google Analytics, you can tell how many times a specific image has been seen.The principle behind Facebook pixel is similar. The pixel is a transparent, 1x1, unique image file that can be embedded on pages outside of Facebook (unique = 1 per advertiser account). That image file, however, sits on Facebook servers. So, each time it is loaded, it increments counters on Facebook's side. But there's more!Each time a user accesses Facebook, using a specific browser, machine, and IP address, this generates a signature that Facebook matches to that user. If the same user uses several devices and several browsers, and don't we all, all of these combinations can be associated to one, single user. And each time the pixel file is being seen by a user... Facebook servers can see which browser is used, which machine and which IP address. In other words, they are able to reconstruct that signature - they know which Facebook user has seen the pixel. As long as a user accesses the page that has a pixel in a way that they used once to log on Facebook, they can be identified and matched to a Facebook ID. But that's not all!When the pixel is seen, Facebook server is also aware on what page it is. Informations on the page can determine what action the user was performing. So Facebook can know things like: who are the users who checked a given product in the last 2 weeks but didn't purchase it? And advertisers can show an ad to that specific group. And that ad can be cross-platform: if you've checked a pair of shoes on your phone while in the bathroom (... it's ok we all do that) but didn't click play because you couldn't see well enough, you can get an ad for that same pair of shoes next time you connect to Facebook on a computer.
How do you find out someone's user i.d. on facebook?
Ok, first, go into their profile page. Then look at the top of the internet browser. The rectangle box should have a lengthy link in there. Look through that until you see id= or something like that. Another way is to right click on their profile and click "view source" and press Cntrl+F while your in the notepad and search for id.
