I once paid a YouTuber £200 to mention my app in a video. Downloads spiked the next day. I felt great about it for about twenty minutes, until I realised I'd also been featured in a Reddit thread that morning. I had no idea which one drove the installs, let alone whether any of those installs turned into paying customers.
That £200 could have been the best money I ever spent, or a complete waste. I genuinely couldn't tell. And that's the core problem with YouTube sponsorships if you're not tracking properly.
Why YouTube sponsorship tracking is so messy
YouTube gives creators plenty of analytics. Views, watch time, click-through rate on thumbnails. What it doesn't give you (the sponsor) is download or purchase data. You're relying on the creator's audience to click a link in the video description, download your app, and buy something. Each step is a black box.
Most sponsors handle this with a promo code. "Use code CREATOR20 for 20% off." Promo codes work, but they leak. People share them on deal sites. Friends text them around. Three months later someone uses CREATOR20 and you attribute it to a creator who hasn't mentioned you since January. The data gets noisy fast.
The other common approach is a simple shortened URL. "Download at myapp.co/creator." You get click counts, which is something. But clicks aren't purchases. Knowing that 400 people clicked a link tells you nothing about how many of them actually opened their wallets.
What you actually want to know
The question isn't "did people click?" It's:
- How many people who clicked that link installed my app?
- How many of those installs became paying customers?
- What's the actual revenue I can tie back to this creator?
- Was the £200 (or £2,000) I spent worth it?
Without that chain — click to install to purchase — you're guessing. You might as well throw darts at a list of creators and hope for the best.
Setting up proper attribution
The approach is straightforward. You give each creator a unique tracked link. When someone clicks it, you capture that attribution data. When they later make a purchase in your app, you connect the dots.
Here's how it works with LinkOwl:
1. Create a tracked link for each creator
Log into LinkOwl, create a link for the sponsorship. Give it a name you'll recognise later — something like "TechReviewGuy-March" works fine. LinkOwl gives you a URL that looks like linkowl.app/c/abc123.
2. Send the link to the creator
They put it in their video description. "Download [Your App] at linkowl.app/c/abc123." When their viewers click, LinkOwl records the click and drops an attribution cookie.
3. The viewer downloads your app
When they hit the App Store page, LinkOwl's SDK picks up the attribution. The install gets tagged with the creator's link.
4. The viewer makes a purchase
If you use RevenueCat or Superwall for billing, LinkOwl gets notified via webhook. The purchase is automatically attributed to the creator who drove that install.
Now you open your dashboard and see: TechReviewGuy drove 180 clicks, 45 installs, and 8 purchases worth £19.92. Your £200 sponsorship cost you £25 per paying customer. Whether that's good depends on your lifetime value, but at least you know the number.
Running multiple sponsorships at once
This is where tracked links pay for themselves. If you're sponsoring three creators in the same month, you need to know which one performed. With promo codes, the data bleeds together. With tracked links, each creator has their own funnel.
You might discover that the creator with 500,000 subscribers drove fewer purchases than the one with 30,000. Audience size doesn't predict conversion. Relevance does. A smaller channel whose audience genuinely matches your app will almost always outperform a bigger channel with a scattered audience.
The only way to learn this is by measuring. And measuring means attribution, not vibes.
What about promo codes alongside tracked links?
You can use both. Promo codes are good for branding — viewers remember "CREATOR20" even if they don't click the link immediately. But treat the promo code as a bonus, not your primary tracking method.
The tracked link captures the full journey: click, install, purchase. The promo code catches the stragglers who typed your app name into the App Store directly and entered the code at checkout. Between the two, you'll capture most of the attribution.
Just don't rely on the promo code alone. It's too leaky to trust as your only signal.
Negotiating better deals with data
Once you've got real numbers, your next sponsorship negotiation gets easier. You can say "your last video drove 8 purchases at £25 each" rather than "we saw a bump in downloads that week." Specifics give you leverage.
Some creators will appreciate this too. If their audience converts well, that's a selling point for them. They can charge more because they can prove results. It's a healthier dynamic than the current model where everyone's guessing and hoping.
The cost question
YouTube sponsorships aren't cheap, especially if you're approaching creators with large audiences. The last thing you want is to spend that budget blind. A per-sale attribution tool like LinkOwl charges 5p per attributed purchase — so if a creator drives 20 purchases, tracking costs you £1. Compare that to not knowing whether your £500 sponsorship was worth anything at all.
For indie developers and small teams, this is the calculation that matters. You're not optimising a £50,000 media budget across 40 channels. You're trying to figure out whether paying one creator was worth it before you pay the next one.
Getting started
If you're about to do your first YouTube sponsorship:
- Sign up at linkowl.app and register your app
- Create a tracked link for the creator
- Send them the link for the video description
- Connect RevenueCat (or Superwall) so purchases are tracked automatically
- Wait for the video to go live, then check your dashboard
The whole setup takes about ten minutes. After that, the data flows in on its own. No manual spreadsheets, no guessing which creator drove what.
You'll know exactly what your sponsorship money bought you. And you'll make better decisions about where to spend it next.
