After you have a list of potential influencers, you need to evaluate their performance and fit for your campaign. You can use different criteria and tools to vet influencers, such as checking their engagement rate, which is the ratio of likes, comments, shares, and clicks to their follower count. A high engagement rate indicates an active and loyal audience. Additionally, you should review their content quality, style, and tone; analyze their audience demographics, interests, and behavior; and compare their rates and expectations. You should also see how they disclose partnerships and endorsements, if they follow the best practices for influencer marketing, how their audience responds to their content and recommendations, if they trust their opinions and expertise, how they communicate and negotiate, and if they are professional and transparent. All of these factors should align with your brand voice, values, goals, target audience, budget, and objectives.
