How It Works

When a visitor reaches your checkout page, the Upstack Pixel fires a checkout event. If that same visitor refreshes the page or navigates back and forth multiple times within a session, multiple events fire. Unique Checkouts deduplicates these by counting only one checkout per session, giving you an accurate count of sessions with purchase intent.
