First-party cookies and custom subdomain

When tracking runs on a subdomain of your site, requests and cookies belong to your domain. They are no longer tied to vendor domains that browsers and blocklists single out.

What we set up

  • A tracking subdomain, such as sst.yourstore.com, pointed at your server container.
  • DNS configured so the subdomain is treated as part of your site.
  • Identifiers set as server cookies on your domain.
  • Tag scripts loaded through your subdomain where the platform supports it.

What you end up with

  • Requests that go to your own domain.
  • Visitor identifiers that are yours, not a vendor's.
  • A base that every server-side tag builds on.
