3plains Geofencing - Location Based Marketing

What is Geofencing?

Geofencing is a location-based marketing strategy that is also referred to as Device ID Targeting (the primary form of geofencing). Every mobile phone has a unique device ID number that is anonymously associated with the carrier of the device. Device ID Targeting and Geofencing take advantage of that by gathering the location data for each device as it gets "pinged" in different locations. This information is beamed to the cloud and made available for marketers to leverage, and ultimately use to serve highly targeted ads to those consumers' devices based on where they have been, where they live, and other location-based factors.

How Does it Work?

To effectively leverage device ID data, we then draw a polygon - or "geofence" - around specific areas that allow us to section off groups of device IDs that have been within that specified area during a given date range. These geofences are so accurate that we can even section off an area as specific as an individual section/department of a store. With Device ID targeting, we are accessing historical data as far back as 12 months ago and as recently as 3 days ago.

Geofencing / Device ID Targeting

Top 3 Reasons Geofencing is Effective:

  1. You can target very specific locations where there is a concentration of your target audience - making a highly accurate pool of ad recipients
  2. You can serve ads to an audience that visited a location during a very specific time period such as a trade show or special event
  3. You can serve ads to people who have visited competitor locations

Other Device ID Benefits

Mobile phones and their device IDs provide a unique view into user behaviors, such as locations that they frequent, where they live or work, their habits and interests, and much more. Device ID allows advertisers to capitalize on these insights with precise targeting, increased engagement, and better efficiency, which ultimately leads to greater ROI/conversions.
