Building ROI case studies from cross-market campaigns—what data actually convinces your CEO?

I’ve been trying to build a compelling ROI narrative for our cross-border influencer campaigns, and it’s way harder than it sounds. Our CEO is asking for proof that these investments pay off, but the data is messy.

Here’s the problem: our Russian campaigns have clear, established metrics (cost per acquisition, influencer ROI multipliers, engagement benchmarks). But our US campaigns are newer, smaller, and the conversion paths are different. We’re running parallel campaigns that look similar on paper but perform differently in practice.

When I try to put together a case study, I end up with something that feels incomplete. Like, I can show revenue impact, but was it the influencers or the organic search traffic from the brand awareness lift? I can show engagement, but was it correlated with actual sales, or just vanity metrics?

I’ve seen other companies pull off these case studies—the ones that get shared around and actually convince executives to invest more. They usually have this narrative structure: problem we were solving → strategy → results → ROI → what we learned. But when I try to apply that to our cross-market work, the “results” section feels convoluted because we’re managing so many variables.

Also, there’s a meta problem: the costs of running these campaigns (team time, platform subscriptions, piloting, learning curves) are easy to measure, but the intangible benefits (relationship building with US partners, learning the market, reducing future market-entry friction) are harder to quantify.

Has anyone here actually built a case study that moved their executive team’s needle on cross-market investment? What was the structure, and what data points did you lead with? And be honest—did you have to make some judgment calls about attribution?

This is exactly where I spend most of my time right now. Here’s what I’ve learned: executives don’t actually want a perfect case study. They want a clear story with defensible numbers.

Here’s my structure:

  1. Objective: Be specific. “Acquire 500 US customers in the wellness category” is better than “test US market.”
  2. Approach: What influencers/creators you used, how you selected them, budget allocated.
  3. Results: Revenue, CAC, ROAS, engagement (in that order of importance).
  4. Attribution: This is where you’re honest. “X% of attributed to direct influencer traffic, Y% estimated from organic lift, Z% influenced by content seeding.” You don’t need 100% attribution—you just need to show you calculated it carefully.
  5. Learnings: What would you do differently next time? This actually builds credibility because it shows you’re not just cherry-picking wins.

For cross-market work, I’d also include a “market entry cost” line. Like, “investment in understanding US creator networks and building partnerships: $X.” That’s part of your total program cost, but it’s separate from campaign performance because it has long-term value.

The CEO doesn’t need to see every data point. Lead with CAC compared to your target, show ROAS (even if it’s imperfect attribution), and then provide backup detail if they ask.

What’s your current CAC in Russia vs. US? That comparison alone can be really compelling for showing market difference.

Also—and this matters—don’t try to prove that cross-market campaigns are better than single-market campaigns. Prove that they work and have clear ROI, even if it’s different. Different doesn’t mean worse. A 2.5x ROAS on a US campaign might be healthy even if your Russian campaigns do 4x ROAS, as long as you’re acquiring customers profitably.

I’d approach this as a measurement system design problem first, narrative second.

You need to decide on your unit of analysis before you run the campaign. If the unit is “cost per acquisition,” then build your tracking around that. If it’s “brand awareness lift + future LTV potential,” then your measurement approach changes.

For cross-market work, I’d recommend running a test campaign with tight measurement from the start:

  • Separate tracking codes for each influencer or creator cohort
  • Clear conversion funnel from click through to customer (or at least to strong intent signal)
  • Cohort analysis: did US customers acquired via influencer have different retention than non-influenced cohorts?
  • Incremental test: can you measure incrementality, not just attribution? (This requires some experimental design, but it’s worth it.)

Once you have one clean case study with defensible numbers, you’ve got your template. Then you can start documenting the intangibles (partner relationships, learning, market positioning) as secondary benefits rather than trying to quantify them.

The executive pitch should lead with: “We tested US market expansion via influencer partnership. CAC was $X. LTV was $Y. ROAS was Z. We learned ABC for future campaigns.” Then, if they ask for more, you have the detailed breakdown.

Biggest mistake I see: teams build case studies that try to answer every possible question at once. Start with the core business question your CEO cares about, answer that clearly, and leave room for follow-up questions.

What’s the decision your CEO is actually trying to make? Is it “do we invest more in US expansion” or “should we continue influencer marketing” or something else? That changes your case study entirely.

I’ve built a couple of these now, and I realize the CEO question is really: “Is this a repeatable playbook or a one-time win?”

So my case studies have started to focus on: what were the replicable elements, and what was lucky? If I acquired 500 customers via influencer campaign, I want to show if that’s because the influencers were amazing, or because the product-market fit was strong, or because the timing was right, or some combination.

For cross-market work specifically, I think you should include the learning curve as a line item. Like, “of our $50K investment, $35K went to direct campaign spend and $15K went to partner relationship building and market learning.” That’s not wasted money—it’s infrastructure for future campaigns.

When I present to my board, I lead with: “here’s the revenue we acquired, here’s the CAC, here’s why it matters strategically (like, now we have 500 US customers and can do word-of-mouth, or we proved market demand, or whatever).” Then I show the detailed breakdown if they want it.

Honestly, the case studies that actually moved my investors were the ones that showed I understood why something worked, not just that it worked. Because that tells them I’ll be able to replicate it.

What’s your hypothesis about why your cross-market campaigns should work, beyond just “let’s try it”? That’s the narrative your CEO actually cares about.

From the agency side, I’ve built dozens of these, and here’s what I’ve learned: your CEO doesn’t care about the influencers. They care about how this affects the business.

Structure it like this:

  • Business goal: What were we trying to achieve?
  • Strategy: How did we use influencer partnerships to achieve it? (Briefly.)
  • Results: Revenue impact, efficiency metrics, customer quality.
  • Implications: What does this mean for our strategy going forward?

For cross-market work, I’d also highlight the partnership angle because that’s a business asset. “We identified and onboarded 3 US-based agencies/creators we can work with going forward.” That’s valuable even if the ROI was mediocre.

On attribution: be transparent about what you know and what you’re estimating. I usually say something like, “X% of conversions are directly attributed via tracking codes; Y% are estimated based on cohort analysis and lift testing.” Executives actually respect that more than pretending you have 100% attribution.

Format matters too. Executives want a 1-page summary they can share, then backups if people want to dig deeper. Don’t bury the headline.

How many cross-market campaigns have you run? If it’s just one, focus on learnings and foundation-building in your narrative. If it’s multiple, focus on trend and optimization.

I think there’s also a relationship angle to these case studies that gets overlooked. When you’re building cross-market partnerships, the ROI isn’t just in the campaign performance—it’s in what doors that partnership opens.

In my case studies, I always include: “partnerships built through this campaign” and “opportunities for future collaboration.” Because that’s real value, especially early in market expansion.

So your CEO case study might say: “Campaign ROI was 2.5x and acquired 200 customers. Additionally, we built relationships with 2 key US agencies that are now part of our ongoing partnership strategy.” That context changes how the CEO evaluates the investment.

I’d also recommend getting your finance team involved early. Have them help you define what “ROI” means for a cross-market expansion campaign, because it might be different from your standard campaign. Maybe they care about customer acquisition cost in a specific region. Maybe they want to see data on customer retention across markets. Build that into your case study upfront.

Have you talked to your CEO about what would actually move the needle for them on this decision? That conversation before you build the case study will save you a ton of time.
