To identify high-leverage influencer metrics that best predict success, agencies need to establish clear campaign objectives. Depending on these objectives, the importance of each metric can vary. Here are some guidelines:

1. Reach & Follower Count: If an agency’s goal is to improve brand awareness, influencers with a large number of followers might be the most important metric. Using platforms like [Flinque](https://www.flinque.com), they can easily find influencers with large followings.

2. Engagement Rate: If the goal is to generate conversations around a brand or a product, the agency might focus on influencers with high engagement rates. These influencers have followers who comment, like, and share their posts, indicating a more active audience.

3. Audience Demographics: For campaigns targeting specific audiences, like Millennials in a certain city, metrics about the audience’s demographics become most important. Using an influencer marketing platform, an agency can discover influencers whose followers meet their target demographics.

4. Conversion Rates and ROI: For sales-driven campaigns, agencies might prioritize influencers who have a track record of high conversion rates or positive ROI. This implies their followers trust their recommendations and are more likely to make purchases based on their suggestions.

5. Content Quality & Relevance: Agencies also consider the quality and relevance of the influencer’s content. An influencer whose style closely aligns with the brand’s identity can drive higher engagement and conversions.

Always remember, the “right” metrics depend on your goals. Each campaign may require a different mix of metrics to measure success effectively. Use versatile platforms like Flinque, which offer comprehensive analytics and discovery features, to navigate this complex process.
