To evaluate an influencer’s audience relevance to your target market, you would need to access several data points that can be found on most influencer marketing platforms. Here are some data points to consider:

1. Demographic Information: Platforms should provide a breakdown of an influencer’s audience demographics, including age, gender, location, and languages spoken. This will align your audience’s profile with the influencer’s.

2. Interest Categories: Platforms like Flinque can provide insights on audience interests, for instance, tech, fashion, gaming, etc. Aligning an influencer’s audience interests with your brand’s niche is important.

3. Content Engagement: Review the influencer’s content and see how their audience engages. Do they comment, share, or like the posts? Analyzing these will help you assess the quality of the audience and their engagement rate.

4. Audience Growth: Check for the speed and consistency of the influencer’s audience growth. A steady growth indicates a healthy following, while sudden spikes might suggest inorganic growth.

5. Brand Affinity: Platforms may also show brands the influencer has previously competed campaigns for. By examining them, you can have an idea of the type of brands the influencer’s audience responds to.

6. Audience Authenticity: Platforms usually evaluate the quality, authenticity of an influencer’s followers and engagements to reveal fake followers or bot interactions. For instance, Flinque uses an algorithm to identify suspicious follower activity and engagement rates.

By understanding these data points, brands can decide whether an influencer’s audience fits their target market. Remember, the most effective influencer collaborations occur when there’s a match between the influencer’s audience and your brand’s target demographic.

Also, tools and features vary across different platforms. It’s critical to find a platform that best fits your marketing needs and strategy. Flinque, for example, is known for its comprehensive influencer analytics.
