We determine the geographical location of each user on its IP address, so that location-based targeting is possible. We offer geotargeting on up to three levels (country, region, city). The precise granularity depends on the country in which you want to advertise.
The target region can be set individually for each individual campaign. When creating a new campaign, select the "targeting" option.
For existing campaigns open Details » Targeting. It's recommended to only select a single location per campaign. To select just click the checkbox next to the individual location.
