1. A method of operating a consumer analytics system in which information about one or more consumers is generated at least in part based on applying a visit detection process for identifying settings corresponding to physical locations visited by the one or more consumers to location data relating to the one or more consumers, the method comprising: receiving input provided by a consumer identifying a setting visited by the consumer at a time; receiving, from a mobile device operated by the consumer, a plurality of units of location data obtained by the mobile device using a Global Positioning System (GPS) receiver, an Assisted GPS receiver, or a wireless network to which the mobile device is connected, each of the plurality of units of location data indicating a respective location of the consumer; identifying, based at least in part on the plurality of units of location data, a physical location of the consumer at the time; and adjusting, using at least one processor and based at least in part on the input provided by the consumer and the physical location of the consumer, the visit detection process for identifying settings visited by the one or more consumers, wherein the visit detection process comprises: identifying an anchor using the plurality of units of location data, the anchor comprising a cluster of locations corresponding to locations indicated by at least some of the plurality of units of location data, wherein identifying the anchor comprises identifying the cluster of locations using the plurality of units of location data; calculating a likelihood that the anchor corresponds to the setting identified in the input provided by the consumer; and determining that the consumer visited the setting when the calculated likelihood exceeds a threshold, and wherein adjusting the visit detection process comprises: comparing the setting identified by the consumer in the input provided by the consumer with the physical location of the consumers; when the setting identified by the consumer in the input provided by the consumer matches the physical location of the consumer, decreasing the threshold so that, when the decreased threshold is subsequently used as part of the visit detection process, the visit detection process is more likely to identify correctly that someone visited the setting; and when the setting identified by the consumer in the input provided by the consumer does not match the physical location of the consumer, increasing the threshold so that, when the increased threshold is subsequently used as part of the visit detection process, the visit detection process is less likely to identify incorrectly that someone visited the setting.
