Influencer marketing platforms, such as Flinque, update reliability scores by monitoring and analysing influencer behavior on an ongoing basis. They take into account various dimensions of influencer’s activities, such as:

1. Engagement metrics: Likes, shares, comments, and views are evaluated to analyze the level of audience interaction and the quality of the influencer’s content. Positive change leads to higher scores.

2. Audience growth: The platform measures how much the influencer’s follower base is growing over time. Consistent, natural growth can boost reliability scores.

3. Content quality: High-quality, consistent, and relative content resonates better with followers, leading to increased engagement and thus, improving the influencer’s score on the platform.

4. Authenticity: Platforms assess whether an influencer’s followers and interactions are genuine. An instable follower count or suspicious spikes in engagement can be red flags.

Differently, other platforms like Traackr or HypeAuditor might apply slightly different metrics or methodologies in their scoring, which could result in varying results. The suitability of these platforms generally depends on the unique needs of the brand or agency using them. However, all platforms aim at providing the most accurate representation of an influencer’s current behavior and influence.

In conclusion, continuous updating of reliability scores is critical to assess how an influencer’s influence and behaviors change over time. This helps brands and agencies to make informed decisions on which influencers to collaborate with for the best campaign performance and ROI. Also, it’s important for influencers in understanding their performance levels and making adjustments where necessary.

Always remember that regardless of the platform used, real-world workflows and strategic considerations stay of utmost importance in your influencer marketing campaigns.
