When using Selligent Web tracking on specific domains, an additional parameter (called “m_i”) is added to each sensor containing that domain. This parameters contains data about the targeted contact, the email sent and the sensor clicked.
The parameter is processed by a JavaScript code added to the first landing page on the external website and creates two cookies on the client computer:
- A session cookie: It is deleted when the contact closes his internet browser.
- A first party cookie: It remains on the computer of the contact.
With this configuration, when a contact reaches the defined landing page, the “m_i” parameter is processed, cookies are created and the parameter is sent back to Selligent environment including interesting values such as items bought, total sales value….
Technical note: Difference between first party cookie
and third party cookie
A cookie is a small script placed on the hard drive of your computer by
the server of a website that you visit. The cookie is placed there for
the purpose of recognizing your specific browser / computer combination
were you to return to the same site.
All cookies have an owner which tells
you who the cookie belongs to. The owner is the domain specified in the
cookie
The word "party" refers to
the domain as specified in cookie; the website that is placing the cookie.
So, for example, if you visit www.widgets.com and the domain of the cookie
placed on your computer is www.widgets.com, then this is a first-party
cookie. If, however, you visit www.widgets.com and the cookie placed on
your computer says www.stats-for-free.com, then this is a third-party
cookie.
Rejection of third party cookies is growing. Increasing numbers of people
are either manually blocking or deleting them regularly. That’s
the reason why Selligent Web tracking uses a first party cookie.
