Lat/Long Targeting allows you to target Lat/Long coordinates and serve ads inside of a small surrounding area. The surrounding area is defined by the Google Plus Codes grid, and only has two pre-determined sizes, stated as a Radius (where Radius is defined from the center of the rectangle to the corner). Options include a Radius of approximately 150 meters or 2251 meters, and may vary slightly depending on the location of the coordinates.
This Audience has a limit of 100,000 coordinates per list.
Enter each set of coordinates on an individual line in the following format:
Line format: [Latitude],[Longitude],[Radius] (Radius can be either 150 or 2251)
To find the Google Plus Code and see the surrounding target area for a set of lat, long coordinates go to the Google Plus Codes website here: https://maps.google.com/pluscodes/ and select ‘Find your code’ at the bottom of the webpage.
Enter an address into the bar at the top of the screen that says ‘Enter a Plus Code or an address’. Once you enter an address you will see a red box on the map over this location and at the bottom of the screen the Plus Code will appear as seen in the image below.
Select the up arrow to the left of the Plus Code to expand the window like this:
The code next to the first blue ‘pin’ symbol is the Plus Code for this specific lat, long coordinate. In this example, 87G8P2R3+PQ.
By removing the letters following the plus sign (in this case ‘PQ’), you can find the Plus Code for the lat, long coordinate and the surrounding area with a Radius of 150 meters. In this example, 87G8P2R3+.
Copy this Plus Code (87G8P2R3+) into the bar that says ‘Enter a plus code or an address’ at the top of the screen to see the designated lat, long coordinate and the surrounding area on the map with a Radius of 150 meters.
This red rectangle is the area that you will be targeting by entering [Lat, Long, 150] into the Custom Audience text box.
If you wish to enlarge this area, target the Plus Code with a Radius of 2251 by entering [Lat, Long, 2251] into the Custom Audience box. To see this area on Google Maps take the code for a Radius of 150, in this example 87G8P2R3+, and change the last two digits before the plus sign to ‘00’. For example, 87G8P200+.
This red rectangle is the area that you will be targeting by entering [Lat, Long, 2251] into the Custom Audience text box.
