What is Influencer Marketing?
Influencer marketing is a form of social media marketing that involves partnering with influential people (creators, celebrities, experts) on social platforms to promote your products or services. Rather than traditional advertising, influencers share your message with their engaged audience through authentic, relatable content.
It's one of the fastest-growing marketing channels – with the market projected to reach $40+ billion in 2026 – because it works. When a trusted influencer recommends something, their audience listens.
Why Influencer Marketing Works
The power of influencer marketing lies in trust and authenticity. While 69% of people don't trust traditional ads, they do trust recommendations from people they follow and respect. This is word-of-mouth marketing at scale.
Types of Influencers: Choosing the Right Size
Influencers are typically categorized by follower count, each with different characteristics:
Nano-Influencers (1,000 - 10,000 followers)
- Best for: Hyper-niche audiences, authentic recommendations, high engagement
- Advantages: Highest engagement rates (3-8%), most authentic, loyal community, low cost
- Disadvantages: Limited reach, takes more coordination for scale
- Typical cost: €100-500 per post
Micro-Influencers (10,000 - 100,000 followers)
- Best for: Targeted campaigns, good balance of reach and engagement
- Advantages: Strong engagement (2-5%), good ROI, industry expertise
- Disadvantages: Still niche-focused, may not have broad appeal
- Typical cost: €500-5,000 per post
Mid-Tier Influencers (100,000 - 1 million followers)
- Best for: Broader reach while maintaining credibility
- Advantages: Significant reach, established authority, media presence
- Disadvantages: Lower engagement rates, higher cost, less personal feel
- Typical cost: €5,000-50,000 per post
Macro-Influencers (1 million+ followers)
- Best for: Maximum reach, brand awareness campaigns
- Advantages: Massive reach, celebrity status, significant media coverage
- Disadvantages: Lowest engagement, very expensive, often less authentic
- Typical cost: €50,000-500,000+ per post

Key Influencer Marketing Metrics
Understanding the right metrics is critical:
Awareness Metrics

Conversion Metrics
- Click-Through Rate (CTR): Clicks on link ÷ impressions
- Cost Per Click (CPC): Campaign cost ÷ clicks
- Conversion Rate: Conversions ÷ clicks from campaign

- Return on Ad Spend (ROAS): Revenue generated ÷ campaign cost
Influencer Marketing Compensation Models
