Many people mention they have geo-fencing capabilities, but may not necessarily provide geo fencing as precise as others. For example, simpli.fi is able to build their geofences as small as the contours of buildings (25 square feet in many cases), while others tap into the wifi networks of particular buildings and locations, and reach mobile devices that ping off of such networks.
We know of several that can only build their geofences around a block, but not a building. The more precise you can get, the more targeted your advertising will be. That is the crux behind geo-fencing…targeting people based on their intent and knowing someone’s physical presence in a location can indicate intent buyers. So this is a critical question worth asking.
