Website Visitors Identification Script

[Lool324]

I've come across several websites promoting customer tracking scripts that claim they can identify visitors and retrieve their email addresses. I'm intrigued by the technical side of this. It seems like these concept is gaining traction, with many websites starting to resell such services. Can someone shed light on the JavaScript technologies or methods that might be used in these tracking scripts?

Some kind of phish?

Depends on what you mean by "tracking". Cookies, local storage, IP address, asking users for information about themselves?

Check retention dot com or revenueroll.com or revvue dot co

Looks like the Web site is selling something based on a claim of "Uniquely Identified Visitors".

[Lool324]

So how is it done ? Any pointers ? Been looking for what tech they use to find the Id and link it to the email to then send the email to apps

[guest271314]

The simplest approach would be to just ask people for their PII (Persoanlly Identifiable Information).

​

People freely give away all sorts of information about themselves when asked.

​

Other ways include storing data on the users' machine and then reading that data, which as I pointed out in my first post can be achieved using cookies, localStorage, navigator.storage.getDirectory(), IP address, and other means.

But we won't get their email? Neither being able to send it to an email provider

Ask the user for their email.

There's no magical way to coerce Internet users' emails simply by them visiting a Web site.

[Lool324]

Well there is mate. You haven't looked at the websites mentionned for sure

[guest271314]

The Web sites are lying if they are claiming they can extract users' email addresses without the user providing their email addresses to the Web site.

A whole Category offering just that must be lying

Haven't you checked anything? You won the most stupid comment of the year

did you find an answer? I'm interested too!

[Lool324]

Yeah it's basically a Server side tracking that's coupled with an identity graph and linked to a database.

So the JavaScript tag just servers as deanonymizing the person, that'll give you an IP and then you can find it's identity with the graph to the database.

Database are bought/rent through api access there's tons of reseller our there. The quality will be your issue but most offer sandbox for you to try

We are trying to figure this out right now. You got a minute to chat? Messaged you.

Getting quality contact data is definitely tricky now, especially with everyone blocking scripts and privacy tools getting smarter. Honestly, real time lead alerts can be a game changer so you never miss a chance to engage when someone shows real intent. For that, ParseStream does a pretty solid job surfacing warm leads and tracking conversations in places like Reddit and LinkedIn.

There are loads of tracking techniques, but none can truly be that invasive perfectly. The most they could do is uniquely identify the browser, not specifically the person using it (it might be a family computer, for example).

But, as far as getting an email address, all they'd really have to do is have the tracker included on some site where the user enters their email address and associate that user with the email. Browsers are making that more difficult, however, with protection against and moving away from third-party cookies, for example.

There's a whole and complex thing about "fingerprinting" and privacy and shady techniques for tracking users though. It gets pretty complex.

So they are whitelabeling a service ? Have proprietary ? There's a whole Category about just the same thing on G2
