Connect an experiment domain
In a project's Domains section, add a lowercase hostname and choose its environment. Enter a hostname, not a URL with a protocol or path. Starter includes one connected domain; Pro includes up to three; Enterprise includes up to five.
This is experiment routing configuration. It does not purchase a domain, change DNS, provide hosting or verify legal ownership of the domain.
Target the right URL
Within an experiment, URL targeting supports contains, equals and starts-with matching. Use the actual URL the browser or server SDK evaluates. Targeting and allocation become part of the frozen plan after an experiment starts.
Changing domains
Domain changes can affect which SDK requests receive configuration. Review the selected project and environment, and check configuration delivery after changes.
