The “earned media value” metric that most influencer reports cite is fuzzy. What matters is cost per acquisition and customer lifetime value from influencer-sourced customers. When we build influencer programs for clients, we track those two numbers and nothing else.

|---|---|---|---|
| 3.65% | ~90% | Fashion, beauty, lifestyle, food | |

| YouTube | Varies by length | 50%+ | Reviews, tutorials, consideration |
| Tier | Follower Range | Avg. Engagement (Instagram) | Brand Preference (2026) |

| Micro | 10,000 – 100,000 | 3.86% | 40% of dedicated budgets |
| Mid-Tier | 100,000 – 500,000 | 2-3% | Growing for targeted reach |

| Mega | 1M+ | 1.21% | Brand launches, mass awareness |
“Most brands track impressions and engagement from influencer campaigns. That tells you reach, not revenue. The brands getting real value from influencer marketing are the ones tracking cost per acquisition and 90-day customer lifetime value from creator-sourced traffic. That’s the only math that matters.”

The global influencer marketing industry reached $32.55 billion in 2025 and is projected to exceed $40 billion by end of 2026, according to the Influencer Marketing Hub Benchmark Report. The industry has more than tripled since 2020.
Brands earn an average of $5.78 for every $1 spent on influencer marketing. Top-performing campaigns achieve returns of $11-$18 per dollar spent, particularly when targeting engaged niche audiences through micro and nano-influencers.
Instagram remains the largest platform, accounting for approximately $22 billion (two-thirds) of global influencer spend. However, TikTok is growing fastest, with 66% of brands now using it for influencer campaigns, and its engagement rates (7.5% for accounts under 100K followers) are roughly double Instagram’s.
For most brands, yes. Micro-influencers (10K-100K followers) deliver 60% higher engagement rates than mega-influencers at roughly one-tenth the cost per post. 40% of dedicated influencer marketing budgets are now spent on micro-influencers, and 44% of brands prefer nano-influencers for their highest engagement and lowest cost.
Most brands allocate 10-20% of their total marketing budget to influencer partnerships. In 2026, 74% of marketers plan to increase their influencer budgets. Start with 5-10% of your marketing budget on a test campaign, measure cost per acquisition, and scale from there.
