Third party cookies
The term third-party cookies refers to the ability of organizations to collect relevant information about the specific target audience and "track" these individuals digitally. So these cookies are set by companies that are not directly involved with the organization. So a third party cookie is a piece of code or a text file that comes from a different domain than the website currently being visited so from an external server. Among other things, these third party cookies can be used to track a website visitor and/or provide that person with targeted advertisements.
A cookie is a piece of code (a functionality) that can be added to a website. After obtaining permission via the cookie wall on the website, the pixel drops a cookie on the user's browser. This allows the Internet behavior of this specific person to be monitored. The difference between a first party cookie and a third party cookie relates to its origin. A first party cookie is used for the purpose of collecting on-site information and cannot function elsewhere as is the case with third party cookies. A third party cookie is a trusted code provided the website being visited uses legitimate code and has not been hacked.
