HypeAuditor identifies the country by analysing publicly available location information on the profiles of the influencer's active audience.
Knowing where a creator's audience is located helps brands and marketers confirm that followers are concentrated in the markets they want to reach, making Audience Demography one of the key signals when selecting influencers for geo-targeted campaigns.
Note: Sometimes audience demography data may be unavailable for a channel if there is not enough reliable data to complete the analysis. See Why is audience demography unavailable for one of the YouTube channels I want to check?
