You can tag and mark conversions that take place outside of LiveBall, even if there is a domain switch. In addition to implementing your "tag", "convert" or "tag & convert" javascript on the external site, you'll also implement "recognition" script on the receiving page and pass necessary LiveBall parameters on your hand-off URL.

After implementing your "tag", "convert" or "tag & convert" script on the external site, follow these steps to accommodate the domain switch:

1. Log into LiveBall under the generic address provided when you first signed-up. 
2. Under Integration, click on External Sites. 
3. Scroll down to the bottom of the screen and click on Advanced Options. 
4. Copy the recognition script and paste on to your external receiving page.
5. Add ?$$ (if first parameter) or &$$ (if secondary parameter) to the end of your LiveBall hand-off URL(s) to pass the necessary parameters.
