On February 4, 2020, Google introduced a Chrome browser update called the SameSite update. This update requires website owners to label their third-party cookies, otherwise, these cookies won’t work properly in Chrome.
Does the SameSite update influence your tracking? No, it doesn’t. Here’s why:
- Piwik PRO only uses first-party cookies, which are set in Chrome browsers without any limitations.
- Starting from version 17.4.0, we add the
SameSite=Laxparameter to tracking cookies. This tells browsers to only set these cookies when the website domain matches the cookie domain for same-site requests or top-level navigation. We also include the
SameSite=Strictparameter for container cookies, which prevents sharing across different domains, even if they belong to the same business. This means our cookies are labeled not to be shared.
- In versions below 17.4.0, we apply the
SameSite=Laxparameter to both tracking and container cookies.
