When picking the most suitable influencer for your campaign, a few key factors should be taken into account:

1. Relevance – The influencer’s content needs to align with your brand. Examine their content to see if it matches your brand values and aesthetics.

2. Audience – Audience demographics of the influencer should much your target market. Platforms like Flinque provide audience analytics to support this decision.

3. Engagement Rate – Look for influencers with high engagement rates. A large following is less important than an active, engaged audience.

4. Past Partnerships and Authenticity – Authenticity builds trust. Research how they’ve integrated promotions in their posts.

5. Budget – It is equally important to align your budget with the influencer tier. Macro-influencers will charge more than micro-influencers.

6. Platform – Determine which social media network aligns best with your target audience.

Comparatively, different platforms have different strengths when it comes to influencer discovery and audience analytics. Take Instagram for example, it’s a great platform for visual products, whereas LinkedIn might be preferable for B2B services.
