Experiment not running

Check lifecycle, draft requirements, URL targeting, snippet config, and visitor assignment.

The experiment must be Running, not Draft, Paused, Completed, or Archived. Its draft checklist needs a challenger, installed snippet, and primary goal. Confirm the browser URL matches exact/contains/regex targeting and the request origin matches the registered domain.

Inspect the snippet config response and verify the experiment bundle loads. A deterministic assignment may place your browser in the control; use a clean browser profile for validation rather than repeatedly refreshing. CSP, consent waiting, or stale page/CDN cache can also prevent application.
