Cookie
A browser cookie or HTTP cookie (also frequently just called a 'cookie') is a little piece of data that a web server stores in a user's browser. It can be used to measure user behavior as well as to save user preferences for the next time the user visits the website.
Data Layer
The data layer is a JavaScript object that can be added to a website to provide a standardized way for data collection throughout a user's journey.
Event
An event is an occurrence that your website or app (or other system) can inform you about so that you can have the option to programmatically react. E.g., As a programmer, you can set up a button click as an event. When you do this, if a user clicks the button, your program will know about the button click event. You can then utilize this click event as a trigger to 'fire' (or execute) a new command - to open a popup, for example.
First-Party Cookie
Cookies characterized by a direct relationship between the browser and the server of the website the user visits are called “first-party cookies”. They are often used to improve the experience of the website for the user (e.g. remembering language settings, previously entered login details, items in a shopping cart, etc.). Learn more.
Tag
A tag is a snippet of code that can be initiated on a website or app based on a defined set of triggers. Such snippets are frequently provided by third-party vendors of marketing or analytics solutions to help track users as well as to monitor or enhance digital marketing campaigns. A tag manager such as Tealium or Google Tag Manager is frequently used to manage these code snippets. With a tag manager, you can inject code snippets into websites and define the conditions under which these code snippets are to be executed.
Third-Party Cookie
These cookies are set by third parties such as marketing vendors. Whereas first-party cookies are characterized by a direct relationship between the browser and the server of the website that the user visits, third-party cookies could be set by the server of an advertising vendor (such as Meta).
