Latest / Influencer Marketing with Fexingo: Creators, Sponsorships, and Modern Endorsement Deals / How Brands Measure Influencer ROI Beyond Likes
Transcript
- Lucas: So there's this stat that keeps me up at night. A brand spends fifty thousand dollars on a single Instagram post from a celebrity with five million followers. Gets a hundred thousand likes. Everyone high-fives. And the brand can't tell you if a single unit sold. Luna: Right — the vanity metric trap. We've all been there. Lucas: Exactly. And look, I'm not saying likes are worthless. They build awareness. But when marketing budgets get squeezed — and they are getting squeezed right now in mid-2026 — the question shifts from 'how many people saw it' to 'how many people bought something because they saw it.' Luna: And that's where the real measurement conversation starts. So what's actually working for brands that do this well? Lucas: Let's start with Sephora. Their Beauty Insider program has been around forever, but they've quietly turned it into an influencer attribution machine. Every creator gets a unique promo code — it's tied to a specific discount tier — and Sephora tracks redemption rates down to the store level. If a creator's code gets used in a physical store, they know. Luna: I've seen those codes. Usually something like 'SephoraLuna20' — easy to remember, easy to track. Lucas: Precisely. And here's the interesting part. Sephora told analysts last year that their top-performing micro-influencer — someone with about fifty thousand followers — drove more attributable revenue than any single celebrity partner they had. Because her audience was almost entirely existing Beauty Insider members who were already in a buying mindset. Luna: That makes total sense. The celebrity might bring awareness to people who've never shopped at Sephora. The micro-influencer brings conversion to people who are already loyal. Lucas: Right. And that's the core insight. The measurement framework has to distinguish between reach and conversion. If you're a brand and you only measure one, you're flying blind. Luna: So what does a good measurement stack look like? Give me the practical tools. Lucas: Three layers. First, trackable links with unique UTM parameters — not just a generic link in bio. Second, promo codes that are specific to each creator, and ideally time-bound so you can measure urgency. Third — and this is the one most brands skip — a brand lift study. Survey a sample of people who saw the content and ask them unprompted if they recall the brand. Compare that to a control group. Luna: That third layer is expensive though, right? You'd need a research partner. Lucas: It is. But it's the only way to measure the halo effect — people who saw the content, didn't click, but later searched for the brand on their own. A lot of brands ignore that and end up undervaluing their influencer programs. Luna: I want to come back to something you said earlier — about performance bonuses. Can you unpack that? Lucas: Sure. A growing number of brands are moving away from the flat fee per post model. Instead, they offer a smaller guaranteed retainer — say, five hundred dollars — plus a commission on sales driven by a unique affiliate link. That aligns incentives. The creator only makes real money if their content actually sells. Luna: But doesn't that risk creators only pushing hard-sell content? The kind that annoys audiences? Lucas: It can. And some brands have overcorrected — they set the commission too high and creators get pushy. The smarter ones cap the bonus at a reasonable level and also pay a flat fee for content usage rights. So the creator gets paid for the content itself, plus a bonus for performance. That way they're incentivized to make good content, not just aggressive calls to action. Luna: That's a nice balance. Let's talk about dark posts — I know you've been following that trend. Lucas: Yeah, dark posts are essentially organic-looking content that's actually a paid ad. But here's the twist — the post itself is never published on the brand's main feed. It only appears as an ad to a targeted audience. So it feels like a genuine recommendation from a creator, but it's amplified by paid media. Luna: And you can measure those differently, I assume? Lucas: Completely. You can A/B test different hooks, different CTAs, different creator content — all within the ad platform. And you can track conversion down to the click. It's the most measurable form of influencer marketing there is. The downside is that it can feel manipulative if it's not disclosed properly. Luna: Disclosure is still a mess, honestly. The FTC has guidelines, but enforcement is inconsistent. Lucas: Definitely. And that's a real risk for brands. If a creator doesn't tag a post as sponsored and the FTC catches it, the brand gets the fine, not the creator. So part of the measurement conversation has to include compliance tracking — are your creators actually using the right disclosure tags? Luna: Good point. So let's pivot to a concrete example. You mentioned Audible earlier — what are they doing that's smart? Lucas: Audible has one of the most sophisticated affiliate programs in the creator economy. Every creator gets a custom landing page that tracks not just sign-ups, but also how many of those sign-ups convert to paid members after the free trial. They pay a flat fee per trial start, plus a retention bonus if the user stays past month three. Luna: That retention bonus is genius. Because the standard model pays per acquisition, not per lifetime value. So creators have no incentive to bring in high-quality users who stick around. Lucas: Exactly. And Audible has the data to show that creators in the self-development niche have way higher retention than, say, comedy podcasters. So they adjust their payouts accordingly. That's a level of granularity most brands haven't even started thinking about. Luna: We should probably address the elephant in the room. A lot of small business owners listen to this show, and they don't have Sephora or Audible budgets. What can a local bakery or a boutique fitness studio do? Lucas: Honestly? Start with a simple unique promo code. Give it to five local micro-influencers. Track how many times each code is used. That's a five-dollar measurement system. You don't need a brand lift study. You need a spreadsheet and the discipline to actually check it. Luna: Yeah, and a lot of businesses skip the basic tracking because they think it's too complicated. But a Google Sheet and a unique code per creator — that's enough to tell you who's driving real business. Lucas: Absolutely. And if you want to get slightly more advanced, use a free link shortener like Bitly with UTM parameters. Then you can see not just how many clicks, but which platform the clicks came from, what device, even the time of day. That's actionable data. Luna: If today's episode was useful to you and you want to keep it ad-free, buy me a coffee dot com slash fexingo helps. Lucas: Yeah, that's the place. We don't run ads — that's a deliberate choice, and listener contributions are what keep it going. So if you value the deep dives, that's the link. Luna: Alright. So we've talked about the tools and the data. Let's zoom out — how do you see this evolving over the next year or two? Lucas: I think we're going to see more brands move to a cost per acquisition model where they only pay when a sale happens. That's already happening in the DTC space. But I also think we'll see more regulation around data sharing. Right now, creators hand over their audience data to brands pretty freely. I expect that to tighten up. Luna: Especially with privacy laws expanding. Europe already has GDPR, and more US states are adding their own. Lucas: Exactly. And that will make measurement harder in the short term. But it'll also force brands to get smarter about first-party data. The brands that build their own CRM and integrate it with influencer campaigns will have a huge advantage. Luna: Final question — if you were consulting a brand that's spending fifty thousand dollars on influencer marketing this quarter, what's the single metric you'd tell them to optimize for? Lucas: Revenue per thousand impressions, or RPM. Not engagement rate. Not follower count. Not likes. How much revenue did that thousand impressions generate? If you can't answer that, you're not doing influencer marketing — you're doing brand awareness, and you should budget accordingly. Luna: That's a great framing. And on that note, I think we've given our listeners a lot to work with. Lucas: Yeah. Go track those promo codes. See you next time.
