What are first-party cookies?

First-party cookies are created and used on a single domain. In other words, they are not shared with other websites or advertising partners.

When you visit a website, a snippet of JavaScript code is launched and a first-party cookie is created for you. Sometimes the website will ask you to accept the cookie in order to continue. And in some cases you will not be able to use important functions of the website unless you agree. For example, if you visit an e-commerce website and it stores personal user information such as email addresses and passwords, that is a first-party cookie.

What are third-party cookies?

Third-party cookies are created on one domain and shared by all third-party domains that use the same tracking code. Its main function is to track user activity online and then display advertisements based on that activity.
Third-party ad tech companies store and manage lines of code to deliver and track ad campaigns across many different websites. So if you are a publisher and want to make money from an ad network, you can place their ad serving code on your website.

What’s the difference between first-party cookies vs. third-party cookies?

Setting the cookie: A first-party cookie is set by the publisher’s web server or a JavaScript loaded on the website. A third-party cookie may be set by a third-party server, e.g. B. an AdTech provider, or via a code that is loaded on the publisher’s website.
Cookie Availability: First-party cookies are available for the domain that created them. A third-party cookie is accessible on any website that loads third-party server code.
Browser Support/Blocking: First-party cookies are supported by all browsers and can be blocked or deleted by the user. Third-party cookies are supported by all browsers, but many block the creation of third-party cookies by default. Users are also taking matters into their own hands and deleting third-party cookies themselves.
