We’ve been running UGC-driven campaigns for about eight months now, and I’m at a point where I need to admit something: the CAC reduction we’re seeing is way less pronounced than I thought it would be.
On paper, everything should be working. We have authentic creators producing content that feels genuine. We’re running it across both Russian and US markets. The engagement looks decent. But when I trace it back to actual conversions and calculate CAC? It’s not where I expected it to be.
I think the issue is that I’ve been tracking surface-level metrics without digging into what’s actually driving (or not driving) customer acquisition.
Here’s what I’m tracking right now:
- Creative performance (CTR, engagement)
- Cost per impression
- Attribution on the campaigns themselves
But I’m not really measuring:
- Whether the traffic from UGC converts differently than other traffic
- Whether there’s a difference in customer quality or LTV between UGC-sourced customers and paid-media customers
- Whether the cultural fit (Russian vs. US versions) is actually impacting conversion rate
- Whether I’m even measuring lift correctly across two markets
I suspect the problem might be simpler than I’m making it: maybe the UGC is good, but the landing page experience is the bottleneck. Or maybe the traffic source doesn’t match the offer. Or maybe I’m not giving it enough time to optimize.
But I also wonder if I’m chasing something that’s not actually possible—maybe UGC just doesn’t reduce CAC as dramatically as everyone claims, and the real benefit is something else entirely (like trust, or brand narrative, or ROAS on a different metric).
Has anyone been through this? Where did you actually find the problem when UGC looked good but CAC wasn’t moving?
I love that you’re asking this question, because it shows you’re actually paying attention to results instead of just going through the motions.
Here’s what I’ve seen happen: the UGC itself is great, but the placement or the surrounding strategy is weak. Like, you have amazing content, but it’s being shown to the wrong audience, or the call-to-action doesn’t match what the content is promising, or there’s just friction between the creative and the landing page.
One thing I’d check: are you actually using the UGC in the way it performs best? Some content is perfect for organic reach—it should live on creator feeds or community platforms. Other content is perfect for paid amplification. Mixing those up can tank your performatively even if the content is objectively good.
Also, and this might sound silly, but: have you asked your creators what they think is working? They produce the content; they often have intuition about what’s resonating with their audience that data might miss.
I’d love to know more about your campaign structure. Are you running the same UGC across both markets, or are you creating market-specific versions?
Okay, let me give you the data troubleshooting path.
First, I want to see your full funnel metrics:
- Impression → Click: CTR (benchmark: 1-3% is normal)
- Click → Add to Cart: What % of clickers are actually interested? (benchmark: 5-15%)
- Add to Cart → Purchase: Conversion rate (benchmark: 30-50% of cart abandoners)
- Purchase → LTV: What’s the actual customer value?
When CAC isn’t moving but engagement looks good, it’s usually a breakdown between Click and Purchase. Meaning: plenty of people are interested, but few are buying. That’s a creative-to-offer mismatch, not necessarily a UGC problem.
Second, I’d measure UGC CAC specifically against other channels:
- What’s your CAC from paid social (non-UGC)?
- What’s your CAC from organic (non-UGC)?
- What’s your CAC from UGC?
If UGC is only 10-15% better than paid social, that might not be worth the effort. If it’s 40%+ better, then you’ve got something.
Third, the dual-market thing: same analysis separately. Russian UGC CAC vs. US UGC CAC. They’re probably different.
What do your funnel breakdowns actually look like? Can you pull that data?
One more thing: have you controlled for volume? Like, if you’re comparing UGC campaigns to other campaigns, are they getting similar ad spend and similar volume of impressions? If UGC is getting 10% of your ad budget and underperforming, that might just mean you’re underfunding it, not that it doesn’t work.
I went through exactly this. We launched with UGC in Russia and thought it was going to be a game-changer for CAC. Numbers looked good, but when we actually traced customers back to source, we realized we were confusing brand awareness with conversion catalysts.
Turned out: yes, UGC was driving traffic. But that traffic was mostly people who were already interested in buying—the UGC wasn’t actually creating new demand, it was just more efficient at converting existing demand.
Once I reframed the metric—instead of asking “does UGC reduce CAC?” I started asking “does UGC convert better than other channels at the same funnel stage?”—everything made more sense.
For us, the answer was: yes, but only for a specific audience segment. Not universally.
How segmented is your analysis? Are you looking at all UGC campaigns together, or breaking it down by creator, by market, by product category?
I’m going to say something that might be controversial: maybe UGC should have different CAC metrics than other channels, and you’re measuring it wrong.
Here’s my thinking: UGC is supposed to build trust and authenticity. That usually means it’s not the first touchpoint—it’s the second or third. By the time someone is seeing UGC, they’ve already been exposed to your brand through other channels.
So comparing UGC CAC directly to “overall CAC” might be the problem. Instead, you should be measuring:
- People who saw Brand Ad → Then UGC → Then Purchased: what’s the incremental CAC for that second touchpoint?
- UGC as a retargeting channel: CAC for people who’ve already engaged with your brand
When I structure UGC for my clients, I’m rarely trying to acquire entirely new customers with it. I’m trying to convert warm audiences and build trust with people who are already aware.
Does that shift change how you’re thinking about the problem?
Also: are you measuring this cross-market, or per market? Because the Russian UGC performance might be fundamentally different from the US performance, and averaging them might be hiding where the real opportunity is.
Quick take from the creator side: if the CAC isn’t moving, it might be because the UGC you’re running doesn’t actually feel like UGC. Like, it might be technically authentic, but if viewers can tell it’s an ad, it loses power.
I notice this a lot: brands get great UGC content, but then they run it through rigid brand guidelines or polish it until it looks like a regular ad. The whole point is that it feels less polished, more real.
If you want to check this: show some samples to people outside your team who don’t know these are ads. Do they still feel authentic? Or do they immediately read as sponsored?
Also, the dual-market thing might be splitting your audience too thin. Like, if you’re running separate campaigns for Russian and US markets, are they getting enough scale individually to optimize? Sometimes UGC needs volume to prove its worth.
Have you tried running the same UGC piece (same creator, same content) across both markets instead of creating market-specific versions?
Let me give you a diagnostic framework:
Step 1: Isolate the Variable
Run a clean test:
- Campaign A: Same messaging, same targeting, standard ad creative
- Campaign B: Same messaging, same targeting, UGC creative
- Same budget, same duration, same audience
- Measure CAC directly
This tells you if UGC itself is the lever.
Step 2: Segment the Analysis
If Campaign B underperforms, break it down:
- By geography (US vs. Russia) — UGC might work better in one market
- By creator tier (high-follower vs. micro) — micro sometimes outperforms
- By content format (video vs. static, testimonial vs. lifestyle) — format matters
- By audience segment (new vs. retargeting) — retention might outperform acquisition
Step 3: Check Your Attribution
This is critical: are you measuring last-click attribution or multi-touch attribution? If you’re using last-click and UGC is a mid-funnel touchpoint, you’re measuring wrong. The UGC might be doing its job (building trust) but getting credit stolen by the conversion pixel.
Step 4: Set Realistic Benchmarks
UGC typically doesn’t have lower CAC than well-optimized paid social for cold audiences. What it usually has is:
- Better ROAS on warm audiences
- Better LTV (customers acquired via UGC often have higher lifetime value)
- Better creative efficiency (lower cost per creative produced)
So the value might not be CAC reduction—it might be LTV improvement or creative efficiency.
Which of these actually matters to your business right now?
