We’re a tech startup with really strong roots in Russia, and we just launched into three new European markets. Naturally, one of my first questions was: “Okay, how do I actually measure whether these influencer partnerships are working across all these different places?”
Short answer: it’s way harder than it sounds. Long answer: keep reading.
The challenge is that we have totally different unit economics across markets. A customer in Russia might cost us $12 to acquire via influencer outreach. That same customer in Germany costs us $34 because the market is more competitive and CPA is higher. So when we run a campaign across both, simple ROI math breaks down.
We also realized early on that the time to conversion varies wildly. A Russian customer might convert in 3 days; a German customer might spend 3 weeks considering. So if we just measure “conversions in the first 7 days,” we’re drastically undervaluing German campaigns.
Here’s what we ended up building:
Step 1: Establish market-specific baselines.
Before jumping into influencer campaigns, we tracked how much it cost us to acquire a customer through “normal” channels (paid ads, organic, direct traffic) in each market. That became our benchmark.
Russia: $12 CAC (customer acquisition cost)
Germany: $34 CAC
France: $28 CAC
Influencer cost varies by creator size, but in each market, we’re paying creators between $500-$3,000 per post.
Step 2: Track cohorts, not campaigns.
Instead of just asking “did this post convert?” we built a cohort tracker. Every click from an influencer post is tagged with the creator’s name, market, and date. Then we follow that cohort for 30 days and see who converts, at what cost, and when.
This is where things got interesting. Some creators drove high-intent clicks (converted at 8-12%), others drove high-volume clicks (converted at 2-3%). Both were valuable, but in different ways.
Step 3: Account for attribution complexity.
Here’s where I’ll be honest: we don’t have perfect attribution. A customer might click an influencer post, then see an ad, then finally buy via Google search. Who gets credit?
We use a multi-touch model where the influencer gets 40% credit (they drove initial awareness), the retargeting ad gets 40%, and the final click gets 20%. It’s not perfect, but it’s way more realistic than first-click or last-click attribution.
Step 4: Calculate market-adjusted ROI.
Once we have cohort data and attribution, the math becomes:
(Revenue from cohort - Cost of influencer post - Cost of all downstream ads) / Total investment = ROI
Then we compare that to our baseline CAC in each market. If influencer campaigns are delivering CAC below our baseline, they’re working. If above, they’re not.
What we found:
- Russia: Influencer campaigns averaging $9 CAC (27% better than baseline). Worth scaling.
- Germany: $38 CAC (12% worse than baseline). We needed to try different creators or product positioning.
- France: $22 CAC (21% better than baseline). Sweet spot.
The hard part? Patience.
Some of these insights took 45-60 days to fully emerge because of the time lag in conversions. We almost cut the Germany campaign after 14 days, but we stuck with it and eventually realized the issue wasn’t the influencers—it was that German customers just need more consideration time. Once we accounted for that, the ROI looked different.
Also: external noise is huge. A competitor launching a sale in one market, a currency fluctuation, platform algorithm changes—all of this impacts performance. So we obsessed over removing as many variables as possible and tracking relative performance (vs. baseline) instead of absolute performance.
What we didn’t expect: the best insight wasn’t a number. It was realizing that German influencers underperform US campaigns not because they’re worse at their job, but because German consumers are more skeptical of influencer recommendations. So we shifted the brief from “soft sell” to “transparent review,” and suddenly performance improved.
If you’re tracking ROI across markets, how are you solving for attribution and time-to-conversion differences? And have you found any external factors that completely blindsided you?
