Geotargeting With Platform-level Keys
Describes the common platform-level key-value pairs you can use to target users with geographic variables across all properties in your Audience Manager account.
Purpose of Platform-level Variables
Platform-level variables let you take data passed in from a particular site and make it available for targeting across all the properties in your Audience Manager account. These variables are formed by key-value pairs with the key prefixed by d_ as shown below.
Adding Values to Platform Level Keys
For some platform-level keys, you can specify the value yourself. With others, the keys are associated with corresponding IP addresses passed in on an event call. In either case, you still need to specify the value when building traits in Trait Builder.
User Defined Platform-Level Keys
You specify the value when building traits with these key-value pairs:
ZIP code (e.g., d_zx=10022 ).
Platform Level Keys Defined by IP Address
We work with Digital Envoy to obtain and update the demographic and geographic data for the keys below. The values for these keys are determined by matching IP addresses to corresponding geographic and demographic data. However, you'll still have to enter the value parameter when creating the key-value pair in Trait Builder.
North America area codes . For example:
Cities and towns. Download the cities list . For example:
Tip : You can use d_city coupled with d_country to be sure you're not targeting two cities with the same name in different countries. You can be even more specific in your targeting by using d_postal_code .
Values correspond to ISO country codes. For a searchable list of codes, see the ISO Online Browsing Platform .
Targeting for the United Kingdom is the only special case that does not obey ISO 3166. You should use "UK" instead of "GB" for targeting in the United Kingdom. To target the Netherlands Antilles, the code "AN" has been deprecated since 2010. The area has been dissolved into five separate territorial units. The implication is that for targeting in the Netherlands Antilles, you should not use "AN," but a combination of the country codes for "CW," "SX," and "BQ." For example:
Trait Name: Czech Republic
Trait Name: United Kingdom
Trait: d_country=CW OR d_country=SX OR d_country=BQ
Trait Name: Netherlands Antilles
Metropolitan area DMA codes. Download the DMA region list (.csv format). For example:
Latitude (e.g. d_lat=40.75). Download the latitudes list .
Longitude (e.g. d_long=73.98). Download the longitudes list .
ZIP codes (exclude the extended +4 code). Download the postal codes list . For example:
2-character abbreviation for a US state. Download the states codes list . For example:
d_state contains repeated values for different states in different countries. For example, d_state == "on" matches multiple states: Ontario (in Canada), Ondo (in Nigeria), Oshana (in Namibia). We recommend to couple this signal with others such as d_country for more specific geotargeting.
Regional alphanumeric IDs. Download the region list . Then, you can use this list to match region IDs to region names.
ISP/organization. Download the ISP List .
The list of all location-based signals comprises all the signals above, in the following order: d_country,d_city,d_region,d_state,d_dma_code,d_postal_code,d_area_code,d_lat,d_long
