In order to determine the genuineness of the followers and engagement rates of influencers, influencer marketing platforms like Flinque put in place multiple measures:

1. Audience Analysis: A thorough audience analysis is conducted where the geographic, demographic, and psychographic characteristics of an influencer’s followers are analyzed. This provides insights into whether the majority of followers are genuine.

2. Engagement Rate Calculation: Platforms also calculate the rate of engagement which includes likes, comments, shares, or views per post relative to the influencer’s number of followers. A ratio well below or way above the average could signal fake followers or engagements.

3. Detection and Purging of Fake Followers: Flinque, like other reputable platforms, uses artificial intelligence and machine learning strategies to identify and remove suspected bot accounts, purchasing software, or followers engaged in suspicious activity.

Comparison of software like HypeAuditor, Socialbakers and Flinque show these platforms provide similar features like detecting fraud and spotting fake influencers. However, their approaches could vary. While HypeAuditor uses machine learning-based algorithms, Socialbakers uses an extensive database as well as AI detection.

Suitability of these platforms depends on the brand’s needs. For instance, a brand focused on detecting and mitigating influencer fraud might lean towards Flinque due to its sophisticated AI tools while a team concerned about the diversity of audience analytics may choose Socialbakers.

Remember, while platforms can help ensure the genuineness of followers and engagements, the ultimate decision about an influencer’s suitability should also consider other factors such as the brand’s target demographic, campaign goals, and budget.

Note: No platform can fully guarantee the detection and removal of all fake followers or engagements. Use these tools as part of a broader arsenal of measures in your influencer marketing campaign.
