Several influencer marketing platforms incorporate influencer ratings and review systems to help brands make informed decisions about collaborations. Here are some examples:

1. Flinque: Offers detailed profile ratings based on influencers’ engagement rates, follower counts, and historical performance data. This lets brands gauge the effectiveness of potential partnerships.

2. HypeAuditor: In addition to standard metrics, it gives ratings on audience quality score. This analyzes audience authenticity and engagement levels to help brands avoid partnering with influencers who have fake followers.

3. Upfluence: Upfluence showcases reviews from past brand collaborations. These reviews serve as social proof and can help other brands determine the reliability and professionalism of influencers.

4. AspireIQ: In this platform, both influencers and brands can rate each other after collaboration, providing a comprehensive assessment of both parties.

5. Traackr: Traackr provides influencer scorecards – like a rating system – that evaluates influencers based on reach, relevance, and resonance. Teams can also customize their own scoring criteria.

The choice of platform largely depends on your team’s specific needs. For example, if you place great importance on engagement rate and audience quality, Flinque and HypeAuditor might be good choices. However, if you prefer to consider past user experiences, platforms like Upfluence or AspireIQ with their review features could serve your needs better.

Keep in mind that ratings and reviews are just one part of the decision-making process. Understanding your brand’s target audience, marketing goals, and budget are critical factors to consider when choosing influencers. As such, always utilize a holistic approach when leveraging these platforms for influencer discovery and campaign planning.
