Ensuring geographic accuracy in influencer discovery data helps brands target the right demographics with their campaigns, thus reducing waste and optimizing ROI. Companies adopt various techniques to maintain geographic accuracy:

1. Platform Integration: Companies use Influencer marketing platforms like Flinque, Traackr, AspireIQ, which integrate with social media APIs to fetch location data directly. These platforms verify, validate, and regularly update the data, thus ensuring accuracy.

2. Manual verification: Manual checks on profiles and posts are conducted as an added layer of authenticity. For instance, if a creator consistently tags a specific city in their posts, it increases the likelihood that they are based there.

3. Influencer self-verification: Platforms may ask influencers to self-verify their location. However, such data might need additional cross-checking for assurance.

4. Audience Demographics Data: Beyond the influencer’s location, the geographical spread of their follower base also matters. Platforms analyze followers’ demographics to deliver accurate location insights.

5. Geo-tagged Content: Companies often look at the geo-tags in influencers’ posts to ascertain their locality as well as the demographics they cater to.

Flinque, for example, provides geolocation data drawn directly from social media APIs along with manual checks and audience demographic analysis. It’s important to note, however, that while all these techniques greatly enhance geographic accuracy, 100% accuracy is challenging due to factors like fake followers, data privacy laws, and movement of influencers. The best approach depends on the brand’s specific needs and goals.
