What are cookies?
Cookies are tiny text files that are stored on a user’s browser. Most cookies contain a unique identifier called a cookie ID: a string of characters that websites and servers associate with the browser on which the cookie is stored. This allows websites and servers to distinguish the browser from other browsers that store different cookies, and to recognize each browser by its unique cookie ID.
Cookies are widely used by websites and servers to provide many of the basic services we find online. If you shop on a website, a cookie allows the website to remember which items you’ve added to your virtual shopping cart. If you set preferences on a website, a cookie allows the website to remember your preferences the next time you visit. Or if you sign into a website, the website might use a cookie to recognize your browser later on, so that you don’t have to sign in again. Cookies also allow websites to collect data about user activity, such as how many unique visitors a page receives per month. All these applications depend on the information stored in cookies.
Third-party and first-party cookies
Cookies are categorized as third-party or first-party depending on whether they are associated with the domain of the site a user visits. Third-party cookies are associated with a domain that is different from the domain of the site a user visits. The third-party cookies used by AdSense for advertising purposes may be associated with the doubleclick.net or country-specific Google domains such as google.com. Note that this doesn’t change the name or content of the actual cookie. The difference between a third-party cookie and a first-party cookie is only a matter of which domain a browser is pointed toward. The exact same kind of cookie might be sent in either scenario.
