Structure & Terminology
An audience is a group of sites imported into your local database that match your search terms and options. Audiences can be built using keywords, keyword snippets, features and services. Cloud accounts build audiences using the data mining service, which actively searches the whole internet for an audience.
Enterprise accounts can additionally create audiences using only the local database. This powerful feature can be combined with country-data, that allows audiences to be created using an entire country's index. You'll need to contact the sales team discuss adding country data to your account.
