The ‘Cities’ dimension reports the city where the hit originated from. This dimension is useful to help determine what the most popular cities visitors originate from when visiting your site. You could use this data to focus on local advertising in these cities, such as billboards or commercials.
Populate this dimension with data
This dimension references lookup rules internal to Adobe. The lookup value is based on the IP address sent with the hit. Adobe partners with Digital Element to maintain lookups between IP address and city.
For AppMeasurement implementations, this dimension works out of the box.
Dimension items include cities all over the world. Example values include "New York (New York, United States)", "Bangalore (Karnataka, India)", or "London (London, United Kingdom)".
Some dimension items can include "AOL", a dial-up internet service provider. Subscribers to this service are assigned an access point based on the country where their account number is established. AOL users use the IP address of this access point. Since this dimension is based on IP address, the geolocation of the access point is used instead of the visitor’s actual location.
Differences between reported and actual location
Since this dimension is based on IP address, some scenarios can show a difference between reported location and actual location:
IP addresses that represent corporate proxies: These visitors can appear as traffic coming through the user’s corporate network, which can be a different location if the user is working remotely.
Mobile IP addresses: Mobile IP targeting works at varying levels depending on the location and the network. Some carriers backhaul IP traffic through centralized or regional points of presence.
Satellite ISP users: Identifying the specific location of these users is difficult, as they typically appear to originate from the uplink location.
Military and government IPs: Represents personnel traveling around the globe and entering through their home location, rather than the base or office where they are currently stationed.
Proxies that obscure IP addresses for privacy reasons: Services like Apple’s Private Relay hide the true IP address by randomly sending data through an intermediary or proxy. This proxy then substitutes a different IP address before forwarding to Adobe.
