The death of the cookie has recently been big news. To digital marketers, the death of the third-party cookie is big news. Remarketing and programmatic display ads will be affected by this. But it will remain the first-party cookie.

What is a first-party cookie?

Within your website or domain, the first-party cookie works, passing user information from one page to another. These cookies collect data from analytics as you visit a website. They remember your settings for the language. They also share your user data on e-commerce sites, so every time you look at an item or add it to your cart, you don’t have to log in.

What is a third-party cookie?            

The cookie from a third party passes from one site or domain to another. The website or domain you are currently visiting is not created by it. All websites that load that third-party code have third-party cookies at their disposal. For ad serving, cross-site tracking, and retargeting, they are used.

Difference between First-Party and Third-Party Cookies:

There is nothing you need to do about your use of first-party cookies, other than perhaps remind users that enabling them improves the performance of the site. You would like to start mining your data for third-party cookies. You should reevaluate your dependence on them as well.
