We ran our first legitimate cross-market campaign with a US macro-influencer (~500k followers) and a LATAM micro-influencer (~50k but incredibly engaged audience, mostly Brazilian and Mexican). Same product, same brand message, parallel timelines, but completely different execution.
I’m sharing this because I learned a ton, and it challenges a lot of what I thought I knew about international campaigns.
The Setup:
- Brand: tech-enabled fitness app (subscription model)
- US Creator: established fitness influencer with a broad, mainstream audience
- LATAM Creator: passionate fitness creator with deep roots in Brazilian fitness community
- Timeline: 3-week campaign (content creation + promotion window)
- Budget: ~$5k each creator (comparable spend, different leverage)
- Metric: conversions, trial signups, 30-day retention
What We Expected:
The US creator would drive higher volume. LATAM creator would drive higher engagement (smaller but more loyal audience). We’d learn about regional audience differences.
What Actually Happened:
The US creator hit their engagement benchmarks but was mediocre on conversions. Their audience is broad, but also largely not in-market for this specific product category. They posted, their followers liked, most scrolled past—or followed to the landing page but didn’t convert.
The LATAM creator outperformed on conversion rate. Their videos felt authentic because they were just sharing how they use the product. No heavy sales language. Just “this changed my routine, here’s why.” Their audience converts because they already trust this person and follow for fitness content specifically.
Here’s the interesting part: total volume was lower (fewer impressions, fewer clicks). But conversion rate was 2.5x higher. 30-day retention was also stronger (LATAM cohort stuck around longer).
The Surprises:
-
The “bigger is better” assumption was wrong. Targeted audience beat broad audience, even at lower volume.
-
The micro-influencer actually drove more efficient CAC (customer acquisition cost) than the macro-influencer, despite the US creator having 10x followers.
-
LATAM audience had higher lifetime value (they stuck with the product longer, had higher engagement, lower churn). Probably because the creator actually uses the product and community had higher fitness culture affinity.
-
The creative approaches were radically different. US creator’s content was polished and lifestyle-forward. LATAM creator’s was genuine, functional, less aesthetically perfect. Guess which one worked better? The authentic one.
-
Timing mattered differently. US creator’s best times: US business hours. LATAM creator’s best times: evening (9pm-midnight, when people work out or plan their fitness). Obviously.
The Execution Challenges:
- Coordinating across time zones and languages was harder than anticipated. We needed someone who could brief both creators in a way that made sense for each.
- Payment and reconciliation took longer (currency conversion, different contractor requirements).
- Attribution was messy until we set up region-specific tracking codes.
- The brand wanted the same messaging and angle from both creators. We had to push back hard and explain that authenticity required different approaches.
What I’d Do Differently:
-
Start with audience alignment, not creator reach. Find creators whose existing audience is your target customer, not creators with biggest followings.
-
Accept that authenticity requires creative flexibility. The brand’s messaging can be the same, but the story needs to be different for each creator and market.
-
Measure cross-culturally from day one. Don’t wait to analyze—set up region-specific tracking, attribution, and KPIs before campaign launch.
-
Brief creators separately, in their comfort language/style. The US creative brief was different from the LATAM one because we respect how each market works.
-
Plan for longer timelines. Coordinating across regions and languages takes time. Budget for that upfront.
The Real Insight:
Cross-market campaigns work when you stop trying to normalize everything and start optimizing for regional differences. The best outcome came when we let each creator do what they do best in their market, with authentic creative freedom, rather than forcing them into a template.
Has anyone else run a direct US-LATAM comparison like this? What surprised you?
This is exactly the kind of case study that should be the default playbook, not the exception. The data you shared—conversion rate 2.5x higher with lower volume, better 30-day retention, more efficient CAC—that’s not a small win. That’s evidence that audience fit beats audience size.
What strikes me most: that LATAM creator with 50k followers outperformed a 500k-follower creator on efficiency. That should fundamentally change how brands allocate budget across influencer tiers internationally.
One question: did you track CAC vs. lifetime value? If LATAM audience had 30% higher LTV and 2.5x better conversion rate, that creator’s ROI was probably 3-5x better than the macro creator. That’s a massive strategic insight.
I’d recommend you run this exact same structure with 3-5 more creators (mix of US macro/micro and LATAM micro/nano) and build an empirical framework showing: audience fit drives efficiency better than follower count. That’s data gold.
Did you measure engagement rate separately from conversion rate? I’m curious if the LATAM creator also had better engagement.
This case study validates something I’ve believed for a while: the best partnerships come when you prioritize authentic fit over maximum reach.
What I love about your approach: you gave both creators space to be authentic instead of forcing them into a unified brief. That’s respect for the creator and respect for each market. That’s how you build long-term partnerships that actually work.
The coordination challenges you mentioned—time zones, language, payment—those are solvable. But the bigger insight is cultural: when brands accept that cross-market campaigns require different creative strategies, everything gets easier.
I’m curious: did the LATAM creator and US creator ever interact or collaborate directly? Or were they completely siloed? I’m asking because I wonder if there’s potential for them to cross-promote to each other’s audiences, which could deepen the partnership.
Also—would you work with these creators again for another campaign? That’s the real test of whether the partnership worked.
This is the first case study I’ve read in a while that actually proves something: efficient growth beats vanity metrics.
Let me reframe your data in strategic terms:
- US Creator: High reach, low conversion, high CAC, standard LTV
- LATAM Creator: Lower reach, high conversion, low CAC, higher LTV
- Winner: LATAM creator, by a significant margin
Yet most brands would have invested more in the US creator because they have more followers. Your willingness to measure what actually matters (conversion, CAC, LTV) instead of what’s easiest to brag about (follower count) is exactly right.
Suggestion: calculate the opportunity cost. If you’d been running both of that $10k campaign budget through the LATAM creator instead of splitting it 50/50, what’s the estimated additional revenue? That’s your future guidance for similar markets.
Don’t just run another test—build a framework. The model here is: find the highest-conversion-rate creator who’s authentic in the market, give them clear strategy but creative freedom, measure ruthlessly. That’s scalable methodology, not just a lucky campaign.
Would you be open to sharing the numbers with me offline? I’d like to compare against some of my own cross-market data.
This case study gives me a lot of hope for international expansion actually working instead of being this constant battle between headquarters and regional teams.
The part that resonates most: you had to push back on the brand’s desire for unified messaging. That’s the real challenge in cross-market work—getting stakeholders to accept that one-size-fits-all doesn’t work. But when you show them the data (2.5x conversion rate), suddenly it makes sense.
When we expanded, the friction points were exactly what you mentioned: time zones, payments, attribution setup. We eventually hired a regional coordinator who lived in LATAM and basically became the bridge between HQ and creators. That person was invaluable—not just for logistics, but for understanding how the market actually works and pushing back on HQ assumptions.
Question: did you invest in that relationship management, or was it mostly project-based? I suspect the creators would work with you again if you showed up with the same respect and creative flexibility.
From an agency standpoint, this is the kind of case study that sells more strategic planning work than traditional media buying ever could.
A few observations:
-
Your data strongly suggests that for subscription products (SaaS, fitness apps, etc.), audience fit matters way more than audience size. That’s an insight that applies across other categories too.
-
The fact that the LATAM creator drove higher LTV suggests they’re not just good at acquisition—they’re actually attracting the right customer. That’s the sign of authentic fit.
-
You mentioned the brand wanted uniform messaging. This is where strategic counsel comes in. The best agencies push back on bad assumptions and educate clients on regional differences. That’s value-add beyond media buying.
If you’re running more campaigns like this, I’d suggest: formalize the process earlier. Instead of learning as you go, develop a hypothesis-driven framework beforehand. “We believe LATAM audience fit will outperform US reach on conversion metrics.” Then test and measure.
Would love to hear how the client responded when you presented these findings. Did they get it, or are they still pushing for macro-influencer volume?
As a creator, I just want to say: thank you for this case study. It validates what I’ve been saying forever—brands get better results when they let creators be themselves instead of forcing them into a box.
The fact that your LATAM creator outperformed the mega-influencer because they were authentic? That’s it. That’s the insight. Audiences can feel when a creator genuinely uses and believes in a product versus when they’re just reading a script.
In my experience, when a brand gives me creative freedom (clear goal, but my approach), I deliver better work. My audience sees it. It converts better. Everyone wins.
I’m curious: did the LATAM creator reflect on the campaign afterward? What was their perspective on why it worked? Sometimes creators have insights about their own audience that don’t make it into the data.
