Geofence is a virtual circular perimeter of a real-world geographic area. The Zeta DSP uses latitude and longitude to precisely identify devices within certain geographic areas.

Users can enter a radius around these precise locations to create targeting zones.

  • Geofences are accurate up to two decimal places (about 1 km) in latitude and longitude.

  • Geofence Targeting is location based and does not leverage user profile information or past user behavior.

    • To simplify, it's a more granular version of basic geo-targeting filters (i.e. Country, State, City, DMA, etc.).

      • Uses precise location at bid time

      • Bidders have filters for identifying bad actors

      • Geo-Fence segments must have a radius greater than 500 meters and less than 5,000 meters

Creating A Geofence




1- Click on the Admin Menu → Targeting Lists → Click Geofences

2 - Once on the Geofence screen - Click Create on the upper right hand corner of the platform

3 - Fill out the following details to create your new Geofence

  • Name - Name the Geofence

  • Locations - Drop the csv file that contains the Latitudes and Longitudes (Steps to follow below)

    • Create a new CSV file. The file must contain the following columns:

      • Location Name: any text string, which may include spaces and punctuation, except for commas (,)

      • Latitude: in Signed Degrees Format in the range -90 to 90 where a preceding minus sign indicates the southern hemisphere, with up to eight decimal places

      • Longitude: in Signed Degrees Format in the range -180 to 180 where a preceding minus sign indicates the western hemisphere, with up to eight decimal places

        • Each location is on its own line. The file should not include a header line. The format within a line is Location Name followed by Latitude followed by Longitude. There are several services that translate street addresses into latitude and longitude, including

Example of the CSV File done correctly shown below:

  • When saving the CSV file for upload, note that the needed file format is dependent on the OS of your computer:

    • Windows User - "CSV (Comma delimited) (*.csv)"

    • Mac User - "Windows Comma Separated (.csv)"

  • Check for and delete commas in the first column for location name. Commas may prevent the uploader tool from processing the file. Other Punctuation marks should fine.

  • Radius - Select the distance in Meters (Eg. 500 meters)

    • To add additional click the (plus) box and enter in distance

  • Subnetwork - Defaulted to the Users

  • Companies - Select the Advertiser you want the Geofence to be located in when setting up targeting

  • Click Save

Edit/Pause a Geofence




1- Click Targeting ListsGeofences. The DSP shows a list of all existing geofences

2 - Click the Geofence name, or its associated notebook icon - Use will see the details of the Geofence as shown to the right

3 - To download the Geofence, click Download CSV File. The DSP prompts you for the location of the CSV file to download.

4- To pause a Geofence and stop the DSP from building the geo-audience follow the step below

  • Click the Pause button as shown to the right

NOTE - Real-time Geofence Locations are active until you remove it from the restriction, or when the Geofence itself is deleted.

  1. Click a Geofence name, or its associated notebook icon from the main Geofence screen.

  2. Click Pause to pause the Geofence from building the geo-audience.

Targeting a Geofence



1 - To assign an existing geofence segment to Campaign Targeting, go to Targeting and select Location in the drop-down menu.

2 - Search for your segment name in the search field, select, and apply to campaign tactics.

Allow up to 60 minutes to see segment populating in Location Targeting screen

3 - As with all Location Targeting, you must include at least one country you want to target. Search for and include any and all countries that contain one or more of the longitude and latitude combinations from the uploaded geofence list.

If the proper countries are not included in the targeting it may negatively impact delivery
