Difference between First Party Cookies and Third Party Cookies
Fri, 09 Apr 2021
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:
|
First-Party Cookies |
Third-Party Cookies |
|
| Setting the cookie | First party cookies are placed on the publisher’s web server or via JavaScript loaded to the site. | The third-party cookie gets loaded by the third-party server using code loaded onto the publisher’s website. |
| Availability of the cookie | Only the domain that created the first-party cookie can access or track it. | The third-party server’s code makes the third-party cookie accessible. |
| Browser support | All browsers support first-party cookies. A user can turn them off, but this often results in poor user experience. | Currently, all browsers support third-party cookies though many have made it a default setting to block them. |
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.
