What is offer targeting?
Offer Targeting is modifying your offer with specific parameters. You can set how the traffic is going to be forwarded to your offer. For example: Day parting (Monday-Friday), only traffic from a specific country etc.
How to use it:
Go into the offer you want to set up the offer targeting and select the tab "Tracking". Select "Create offer targeting"
Now the Offer Targeting setup window will pop up. Here you have a variety of different parameters such as: country, city, connection type, day parting.
After setting up the targeting you can save them. Once you've set it up, you'll have the details of your offer targeting displayed. You can enable or disable it at any given time by going to "Edit Targeting" and switching the button off.
