Discovering micro-influencers, who often have higher levels of audience engagement due to their more niche focus, involves several steps:

1. Define Your Goals: Understand what your brand wants from an influencer campaign. This may include increased brand awareness, higher sales, or more social media followers.

2. Audience Analysis: Use analytic tools to examine your target audience’s interests, demographics, and consumption habits. You can use various influencer marketing platforms like Flinque or alternatives like Hootsuite or Buzzsumo for this research.

3. Keyword Research: Search for influencers within your industry by using specific keywords. For instance, if your brand is about vegan cosmetics, you might want to search keywords like “#veganmakeup” or “#crueltyfreecosmetics”.

4. Engagement Rate: Micro-influencers tend to have higher levels of engagement. Monitor the influencer’s posts to see how actively their audience interacts with their content.

5. Authenticity Check: The influencer’s posts should align with your brand’s message and values. Their authenticity is crucial for gaining the trust of their followers.

6. Track Ongoing Performance: Once you’ve discovered and engaged with an influencer, continuously measure their impact on your brand’s performance.

Flinque, for example, provides tools to track campaign performance in real-time and identify top-performing influencers. Similarly, platforms like Sprout Social or Klear also provide analytics for tracking and benchmarking influencers.

The selection of the right platform largely depends on your team and campaign needs. For instance, you might prefer platforms like Flinque for its ease of use and real-time analysis features, while others might prefer Hootsuite for its social listening capabilities.

Remember, the right choice of micro-influencers will largely depend on the campaign’s goals, target audience, and the influencer’s authenticity and engagement levels.
