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.
Where can I set my desired target region?
The target region can be set individually for each individual campaign. When creating a new campaign, select the "targeting" option.
For existing campaigns open 'Campaign Settings » 'Traffic Targeting / Filters'. You can select one or any combination of multiple geographic targets. To select just click the checkbox next to each individual location.
