I’ve been measuring influencer campaign ROI across US and LATAM markets for about eighteen months now, and I keep running into this frustrating measurement problem that I don’t see people talking about enough.
The issue: every metric tells a different story depending on which market you’re looking at, and they’re not directly comparable.
Here’s what I mean. In a recent campaign, a US-based creator got 8% engagement rate, 2.3% CTR, and a conversion rate of 1.8% on a product link. Their LATAM counterpart—same tier, similar audience size—got 12% engagement, 5.1% CTR, but only 0.9% conversion rate. On the surface, the LATAM creator crushed it. But dig deeper and the story changes: the US creator’s audience was smaller but had higher purchase intent (they were closer to buying anyway). The LATAM creator reached a bigger, more engaged audience, but they needed more nurturing before converting.
So which campaign was actually more successful? Depends on if you’re optimizing for reach, engagement, or revenue. And depending on which metric you chose, you’d build completely different strategies going forward.
The real problem is that standard agency reporting doesn’t account for market maturity differences. In mature US e-commerce markets, conversion happens faster. In developing LATAM markets, conversion funnels are longer because there are more friction points—payment infrastructure, shipping, brand familiarity. A 0.9% conversion rate in LATAM might actually represent way more valuable customer acquisition than a 1.8% rate in the US, once you account for LTV differences and market size.
I started building hybrid dashboards that track engagement metrics separately from conversion metrics, and then I layer in market-specific context about payment adoption, shipping times, and competitive landscape. It’s messier than a single unified report, but it’s actually honest about what’s happening.
The campaigns I feel most confident about now are the ones where I set separate success criteria for each market upfront, rather than trying to force them into a global KPI framework. “Reach and engagement in Mexico, trust-building and repeat purchase in the US” ends up being a more useful strategic framework than “10% overall lift across markets.”
How are you all handling this? Are you forcing everything into one global metric, or are you building market-specific measurement frameworks?
