I don't just mean demographics like what Facebook Insights offer, I mean that if a user visits your business page, you can be notified of their full name and email. Is it possible to obtain such information by just visiting a page? I am not paranoid, I was just hearing from a fellow that this "Social Marketing" Company offers such service.
I believe that if they could do that, it would be violating A LOT of privacy rules regarding Facebook. Even if you can't do that, can you track a users identity if they click the Like button?
I am just getting into the social marketing thing for my web design and I really wish to know what apps these "Social Marketing" companies are using to obtain such data.

NOTICE: They said they can track a users full name and email even if they do NOT click the Like button

If there is an app or method of doing that, I would be very thankful if you could share.

Short answer: no — you cannot be silently notified of a visitor’s full name and email just because they loaded your Facebook Fan Page. Page admins get aggregated metrics (page views, reach, demographics) and can see profiles that publicly follow or like the Page, but Facebook does not hand out private contact details or a log of anonymous visitors. (facebook.com)

Clarifying the one real exception mentioned by : if your Page hosts an app (a Page Tab, Canvas app, or an external site the user logs into with Facebook), that app can present Facebook’s Login/OAuth dialog asking for permissions such as public_profile and email. If the person explicitly grants those permissions, the app receives whatever fields the user consented to (name, email when available). That’s a consented flow — not a stealth tracking trick — and it’s the mechanism behind many games and integrations. (developer.reachfive.com)

Practical points and red flags (for and ): a) Clicking “Like” does not give you someone’s email; it only records the like and, where public, the person’s profile. b) Any vendor claiming they can identify non-consenting visitors is almost certainly misleading — such methods would breach Meta rules and privacy law in many jurisdictions. Always ask for the app’s Facebook App ID, App Review status and a privacy policy showing lawful data provenance before buying such a service. For legitimate lead capture, use Facebook Lead Ads, an explicit Facebook Login / opt‑in form, or a CTA that sends users to a landing page where they willingly submit contact info.

If a company still claims they can do what described, request a live demo (with test accounts) showing the exact flow and the App Dashboard evidence; if they refuse or their answers are vague, treat it as a scam and report it. (facebook.com)

This is possible. When accessing the page, the user will be presented with a Facebook dialog box from Facebook asking them if it is okay to share their public profile Facebook information with the current website.

Sometimes you see a similar dialog box when loading Facebook games such as Farmville.

It is really possible for the company to get the full name and email by just visiting the business page? I have no idea even when a person clicks the like button. Thanks for the prompt answer here, @cscgal. That is great help for my curiousness in this matter.
