I’ve been thinking about this a lot lately. We ran the same campaign on TikTok in three countries—Mexico, Brazil, and the US—and the audience response was wildly different. Not just in numbers, but in how people engaged.
In the US, we got decent reach but engagement was flat. In Mexico and Brazil? The same creative got 3-4x higher engagement, more comments, actual conversation happening. And it made me realize: I wasn’t just dealing with different languages. I was dealing with fundamentally different platform cultures.
In Brazil, especially, TikTok is where real conversations happen. People actually read longer captions, they want context, they engage deeply with creators they follow. In the US, it feels more… transactional? You scroll, you double-tap, you move on.
And then there’s Instagram. In Mexico, Instagram is still THE platform for influencer culture. Everyone’s there. But in the US, it feels like it’s fragmenting—people are bouncing between TikTok, Reels, Stories. The platform doesn’t feel as central anymore.
YouTube is interesting too. In Colombia and Mexico, long-form content gets watched way more than I expected. In the US, everyone’s optimizing for 60-second YouTube Shorts.
What I’m realizing is that if you’re doing cross-border LATAM campaigns from the US, you can’t just translate your US platform strategy and hope it works. You actually need different strategies for different countries.
Have any of you worked across multiple LATAM countries and noticed how platform culture shifts? And more importantly—how do you actually structure your budget and content when platforms matter that differently?
