SameSite Cookie Change

targeting options

Effective February 17, 2020, ChromeFirefoxEdge, and other major browsers will be changing their default behavior in line with the IETF proposal, Incrementally Better Cookies.

From this change:

  • Cookies without a SameSite attribute will be treated as SameSite=Lax, meaning that the default behavior will be to restrict cookies to first party contexts only.
  • Cookies for cross-site usage must specify SameSite=None; Secure to enable inclusion in third party context.

This will become the default behavior in Chrome 80, and is planned for a stable release in February 17 2020. If you currently use or drop cookies on Trafficjunky’s sites with your ads, you will need to make this change before that date to be able to track your customers.
