GEO
AffiliateThe target country (or region) of an offer or campaign. Payouts, competition, and rules vary by GEO: tier-1 (US, UK, etc.) pays the most but costs the most. Traffic is usually bought and reported per GEO.
Example
The same sweepstakes offer pays $2.50 in tier-1 GEOs and $0.40 in tier-3.
