The ROI Black Hole
Ask any founder: "Is your influencer seeding program profitable?" Most will answer: "I think so... but I'm not really sure."
Unlike paid ads with clear ROAS metrics, influencer seeding involves:
- Product costs (COGS)
- Shipping costs
- Time/labor costs
- Indirect brand awareness (hard to measure)
- Delayed conversions (someone sees a post, buys 2 weeks later)
This complexity leads many brands to fly blind — spending thousands per month without knowing if it's working.
Key Metrics to Track
1. Cost Per Post (CPP)
Formula: Total Program Cost ÷ Number of Posts Created
Example: You sent 50 products ($30 each = $1,500) + $500 shipping = $2,000 total. 20 influencers posted.
CPP = $2,000 ÷ 20 = $100 per post
Benchmark: A good CPP for micro-influencers is $20-50 for seeding campaigns. $100+ means low post rates or expensive products.
2. Post Rate
Formula: (Influencers Who Posted ÷ Total Influencers Gifted) × 100
Example: 20 out of 50 posted = 40% post rate
Benchmark: 30-50% is healthy. Below 20% indicates a problem (wrong influencers, poor product-market fit, or lack of follow-up).
3. Earned Media Value (EMV)
Formula: Total Impressions × CPM Rate
EMV estimates what you would have paid for the same exposure via ads. If 20 posts generated 500,000 impressions at a $10 CPM:
EMV = 500,000 ÷ 1,000 × $10 = $5,000
Compare EMV to your program cost: $5,000 EMV vs $2,000 cost = 2.5x ROI
4. Direct Sales Attribution
Use unique discount codes or UTM links per influencer. Track:
- Clicks from influencer content
- Orders using their code
- Revenue generated
Warning: Many conversions happen via "dark social" (people see a post, Google your brand later). Direct attribution often undercounts by 30-50%.
5. Blended Cost Per Acquisition (CPA)
Formula: Total Program Cost ÷ Total Orders Attributed
Compare this to your paid ads CPA. If seeding CPA is lower, shift more budget over.
