How facebook team uses "custom parameters sent" in the facebook pixels? - facebook

I recently checked airbnb and once I applied filters on the website, it fired Facebook pixel with all the information in custom parameters.
How is this done i.e. how can facebook show specific ads to people who have viewed certain page on our website? After this was fired I started getting, relevant suggestions when I accessed facebook through same browser. Does this work only when the user is logged into facebook from same browser?
Is it something like facebook will associate this pixel fired with already logged in facebook user on that browser? And if the same user comes to facebook from any other device, he/she would be shown ads based on that pixel?

How does facebook pixel knows which conversion came from which facebook ad?

I was going through facebook pixel and was a lot confused about how does facebook pixel knows which conversion came from which facebook ad ?
Suppose i have this url http://example.com with facebook pixel installed and i have posted two ads on facebook namely Ad1 and Ad2. Users clicks on some ad and land on my url page.
So how does pixel tell facebook that that particular user came from which ad ? and does the pixel even get into such detail ?
And also, does a pixel fire whenever a user lands on above mentioned url or only when the user came from a facebook ad ?
Facebook knows which facebook users were exposed to ads and provided that same user has been using Facebook in that same browser, they can attribute the pixel fire back to that user.
The pixel should fire for all page loads not just those for when people visit from a Facebook ad.
If there are multiple ads that a user was exposed to, Facebook would give credit to the ad that was most recent.

Can Facebook SDK allow for iOS app (linked with a facebook app) to post directly to a particular page?

I am trying to make an iOS app integrated with the Facebook SDK that allows the user to post directly to a facebook group page and receive updates directly from the group page through the app, as an alternative to the facebook app.
I know that the Facebook dialog class in the latest SDK allows us to share a status directly to one's wall but I have yet to find a way to post it to a page other than the user's wall. Is there a way to gain access to a facebook group page and retrieve the posts from the page and also post directly to it?

How does Facebook track Like or other activities on my site?

I am using Addthis.com's service to add facebook 'like' button onto my site.
Now I want to manually add some facebook social plugins to my site:
http://developers.facebook.com/docs/plugins/
As I see, some plugins require to enter 'app_id', but I didn't specify my 'app_id' for Addthis.com's buttons, so I would like to ask how does facebook track those 'like' or other activities on my site??
For example, if a user clicked 'like' on Addthis.com's button on my site, would this user appear in the "Like Box" and "Facepile" plugins that I manually added to my site??
Thanks!!
AddThis
When using AddThis, the app itself, gets the current page that is liked or the specified Facebook page. When you are referring to the app_id for AddThis, it is their own id that allows you to log into http://www.addthis.com and access their custom statistics page.
Facebook
When using the Facebook like button or other plugins, Facebook records the number of times someone has pressed the button. It also includes shares and reposts in this number. Using the Facebook API you would be able to seperate the numbers (whether like or share) if desired.
Facebook API
In order to access the information recorded by Facebook you must register and app with them and that will give you a Facebook app_id. This can then be used in any of their plugins.
Overall
Since the AddThis app transfers the information to Facebook, Facebook will display your like and share count in any of its plugins.

Yes.

Use Facebook Graph API to serve your purpose. Do this:
Add a Facebook login button to your website using Facebook Authentication refer Login subheading here
Make sure you ask for Advanced Permission from your user to allow your application to use his read_stream. This will allow your app to access logged-in user's posts that includes his wall posts. See details here
Parse the JSON object and display. You may want to have a long-poll or AJAX call ready to poll the new messages at regular intervals.
