Create a nested Sub Rule to identify traffic from social referrers.

1. The Sub Rules segment title remains selected, drag another Sub Rule decision node to the new canvas. The Sub Rule dialog box displays.
2. Enter a name for the Sub Rule in the Title text box. We have called this Sub Rule Social Referrer.
3. Select the Save button. The Sub Rule displays in a new canvas.

   You have now created a nested Sub Rule and can build a rule to determine whether traffic came from a Social Referrer.
