What Are First-Party Cookies?

First-party cookies are primarily about streaming the users’ experience on a website. The host domain (the website you visited) creates first-party cookies. These are seen as an agreement between the site and the user to aid things in running better.

An example of a first-party cookie is Amazon when a user signs into an e-commerce website. The web browser sends a request in a process that offers the highest level of trust that the audience is directly interacting with Amazon. The web browser will save this data file to the user’s computer under the “” domain.

If first-party cookies were blocked, you would have to sign in every time you visited, and you could only buy a few items while shopping online, as your cart would reset after each item was added.

What Are Third-Party Cookies?

Third-party cookies are often generated by parties other than the website owner. They’re commonly deemed “non-essential cookies” by data privacy laws.

These are tracking cookies generated by advertising companies. Their tracking helps you to see advertisements for items like those you purchase.

Third-party cookies primarily do three things:

  • Tracking: They track you via various websites to see what you may purchase.
  • Retargeting: They send you to a website that sells items you may like.
  • Ad-serving: They deliver personal ads that target your needs.

Familiar with the former example, third-party cookies work when a customer goes shopping on Amazon. They may browse two products and spend time on the product pages.

When the customer decides to buy one product, for instance, the yellow hat over the yellow shoes, they might later receive emails and other ads for the yellow shoes they saw but never bought.

Even if the customer closes their browser and ends the session, that tracking data will be on their computer.

Yes, second-party cookies exist; however, they have a more limited purpose. They share data between three entities:

  • The consumer.
  • The website they visit.
  • The website’s partner/s.

Second-party cookies are mainly used in data-sharing agreements, though their usage is not widespread. All of them represent data collection partnerships.

Thus, they are only useful to internet businesses that are also data brokers.

Users and regulators have applied pressure to protect online privacy, and many employees in large tech organizations have blocked third-party cookies on their websites. In June 2021, Google announced its plans to remove third-party cookies on Chrome.

If they have not already, publishers and advertisers need to explore other marketing strategies because the end of third-party cookies is quickly accessed.
