Safari 16.4 : Impact on Server-Side Tracking
Safari 16.4, the latest version of Safari released in April 2023 by Apple, has brought about significant changes in terms of cookie management and server-side tracking. These changes have a major impact on the digital marketing world, upending strategies for user tracking and campaign personalization. They also affect digital marketing specialists who rely on precise traceability of user behavior.
In this article, we'll decode these changes and the solutions to understand how to address them.
Safari 16.4 and cookie management : what you need to know
Cookie management has been directly impacted by the arrival of Safari 16.4, especially in the context of server-side tracking. Discover how this affects your Server-Side tracking strategy !
One of the significant changes is the lifespan of First-Party cookies set by the server. This duration is now limited to a maximum of 7 days, compared to 365 days before the update.
To better understand how this works and the conditions, here are some explanations on how Safari 16.4 now manages cookies:
Imagine a user browsing a website; the website's server then sets a cookie with a specific IP address (e.g., 192.168.1.100). If a third-party server (hidden behind a CNAME) from the website the user is browsing attempts to set a cookie with an IP address where the first half differs (for instance, 203.0.114.1), then this cookie will be limited to a maximum duration of 7 days.
In other words, if the tracking server's IP address doesn't share the first two octets with the website's servers, Safari doesn't consider the cookie as First-Party.
