A method of operation of a navigation system includes: delivering a first message with a target location for a first business for displaying on a device; receiving a current location for locating the device; calculating a business detection geofence encompassing the target location for detecting the location of the device in the target area of the business detection geofence; detecting an entry to the business detection geofence for detecting the current location of the device being at or within the business detection geofence; detecting an encounter between the device and the business detection geofence for the entry into the business detection geofence in a response to the first message; and determining a uniqueness of the encounter for indicating the encounter between the device and the business detection geofence.
