Location Fraud

Advertisers pay a premium for geo-location targeting to serve their ads in specific regions only, with traffic in some regions being more expensive than others. Location fraud involves manipulating users’ location information to match the advertiser’s targeting criterion. For example, for a campaign targeting users in a country with high CPMs, a bad actor may provide traffic from regions with low CPMs by manipulating the location to meet the campaign criteria and steal the higher CPM.
