Abstract: In one embodiment, a computing system receives a number of location updates sent by one or more users. These location updates may have different geographic locations, but refer to the same place or point of interest. Each location update corresponds to a user visit to the place or point of interest, and each location update is determined by a mobile client device of the corresponding user. The mobile client device may determine a location update by any one or more of a number of location methods available to the mobile client device. The computing system determines a ping compensation factor to be associated with the place or point of interest. The ping compensation factor is based on a total number of visits to the particular place, versus the subset of visits to the particular place determined by a first location method from the number of location methods.
