Discovering the right influencers for your brand can be a critical undertaking, which typically involves the following primary considerations:

1. Relevance: Look for influencers whose content aligns with your brand’s values and products. Their followers should consist of your intended target audience.

2. Reach: Consider the size of the influencer’s audience. If your goal is to gain widespread exposure, partnering with influencers boasting larger followings might be your best bet. However, don’t dismiss micro-influencers, who can offer higher engagement rates.

3. Engagement: Influencers with high engagement rates (likes, comments, shares) are valuable as this signifies their followers are actively interested in their content.

4. Authenticity: Authentic influencers who share real experiences or professional expertise with their followers tend to be more trusted.

5. Consistency: The influencer’s posting frequency and consistency also matter. Frequent and regular content helps keep the audience engaged.

Some well-known platforms that provide influencer discovery tools are Heepsy, Klear, and BuzzSumo. Each has different search and filter functionalities, but the main purpose is to aid you in finding influencers that fit your requirements.

Flinque, for instance, offers features like detailed influencer profiles, keyword searches, and engagement metrics which can be invaluable for your discovery process. It helps streamline your search process, but remember suitability ultimately depends on your specific needs.

Performing your due diligence during this discovery phase can be greatly beneficial to your campaign outcomes, ensuring the influencer not only aligns with your brand but can also effectively engage their audience leading to better ROI for your efforts.
