Real Numbers: How Much I Earn from Tech Affiliate Links (Build in Public Style)

Okay, pull up a chair. I'm about to get more transparent than most creators ever do with their finances — and honestly, that's the whole point of this piece.
If you've been following the build in public movement for any length of time, you know we believe in showing the messy receipts, not the polished LinkedIn humblebrag. So here's my real numbers. Not cherry-picked. Not "I made $10K in my first month" hype. The actual, slightly embarrassing, slowly-climbing truth.
I've been promoting tech affiliate links for over a year now. Some months I made $47. One month I cracked $1,200. Most months sit somewhere in between. And I think that's a much more useful story for anyone considering this path than the screenshots the gurus post.
Let me break down exactly where the money comes from, how the math actually works, and why I ended up focusing most of my affiliate energy on the Global API program specifically.

Why I'm Sharing This (And Why You Should Care)

I spent six months lurking in affiliate marketing forums before I wrote my first honest income post. I kept seeing two types of content:

1. The "$0 to $50K in 30 days" YouTube thumbnails that turned out to be fake
2. The "passive income is a lie" doom posts from people who gave up after a week Neither was useful. So when I started actually building this thing, I committed to documenting it properly. Every month. Real numbers. Real screenshots of dashboards. Real talk about what flopped. Here's what I'll cover:
3. The exact commission structure I work with (no hand-waving)
4. Three realistic income scenarios based on actual audience sizes
5. The compounding effect that makes recurring commissions magical
6. Why I'm recommending the Global API program at the end of this piece If you're not into the build in public ethos, this article probably isn't for you. But if you want to see the actual math behind affiliate revenue — and understand why I think it's one of the most underrated side hustles in tech — keep reading. # # The Math Behind Affiliate Income (No Fluff) Before I share my personal numbers, let me explain how this whole thing works at a mechanical level. There are only three variables that determine what you earn: Variable 1: Clicks. How many people actually click your referral link. This depends entirely on your traffic and how naturally you integrate the recommendation. Variable 2: Conversion rate. What percentage of clickers actually become paying customers. In the tech space, this usually lands somewhere between 0.5% and 3%, depending on how qualified your audience is. Variable 3: Commission per conversion. How much you earn per signup, plus any recurring monthly kickback. That's it. Everything else — content quality, niche selection, "secret strategies" — just influences those three numbers. The product itself doesn't matter if all three variables line up in your favor. # # How the Global API Commission Structure Actually Works Here's where I get into specifics, because this is the program I spend most of my affiliate time on and the one I'll recommend at the end. Global API runs a tiered commission structure that looks like this:
7. 15% commission on the first order from any new customer you refer
8. 8% recurring commission every month they stay subscribed
9. 10% premium tier commission for higher-end plans
10. Access to over 150+ AI models through one unified platform (which makes it genuinely easier to recommend) Let me translate that into actual dollar amounts based on their pricing tiers, because percentages mean nothing without context: Pro plan at $19.99/month:
11. First-order commission: $3.00
12. Recurring monthly: $1.60 Business plan at $49.99/month:
13. First-order commission: $7.50
14. Recurring monthly: $4.00 Scale plan at $149.99/month:
15. First-order commission: $22.50
16. Recurring monthly: $12.00 Now here's the thing most affiliate guides skip: those recurring numbers compound. If someone signs up through your link in January and stays subscribed through December, you earn 12 months of that $1.60 (or $4.00, or $12.00). Every. Single. Month. That's why I stopped chasing one-time payout programs. Recurring revenue changes everything. # # My Real Content Strategy (And What Actually Drove Clicks) Here's my monthly content split, in case you're curious what works:
17. 2 long-form blog posts per week (roughly 1,500-2,500 words each)
18. 1 YouTube tutorial per month
19. 1 newsletter issue per week to ~8,500 subscribers When I first started, I made the classic mistake of stuffing affiliate links into every paragraph like a desperate car salesman. Conversion rates tanked. Trust tanked. Everything tanked. What worked better:
20. One contextual mention per piece, integrated naturally into a tutorial or comparison
21. A single call-to-action at the end of each article
22. Honest disclosure at the top (build in public transparency actually builds trust, weirdly) My average click-through rate sits around 1.8% on blog posts and closer to 3% on YouTube videos where I'm actively demonstrating the product. Conversion from click to paying customer runs about 2% across the board. That means for every 1,000 readers, I generate roughly 18 visitors to the affiliate link, and about 0.36 of those become paying customers. On the Pro plan, that's about $1.08 in first-order commission plus recurring revenue from anyone who sticks around. Multiply that across enough content and you start seeing real numbers. # # Three Real Scenarios Based on Audience Size Let me walk through what this actually looks like at different stages of audience growth, because "how much can you earn" is completely meaningless without knowing your starting point. # # # Scenario 1: The Beginner (5,000 Monthly Blog Visitors) You're just starting out. Maybe three months into blogging. You write three comparison articles about API platforms, each getting around 500 views per month. With a 1% click-through rate, that's 15 clicks per month across all three posts. At a 2% conversion rate, you're converting about 0.3 people per month, or roughly 3-4 per year. At an average of $5 per referral per month in combined commissions, you're looking at $15-20 monthly after the first year. Is that worth it? Let me do the math differently. Those three articles took me maybe six hours total to write. They keep earning for years. Over three years, we're talking $500-700 in commissions from a half-day of work. That's roughly $100+ per hour of effort — just spread out over a long time horizon. Not life-changing monthly, but genuinely excellent hourly if you think about it as compounding content assets. # # # Scenario 2: The Intermediate Creator (10K YouTube Subscribers) This is roughly where I was six months in. You publish one API tutorial per month on YouTube. Each video gets 8,000 views in the first month, then trickles another 20,000 over the next year. With a 3% click-through rate from the description link, that's 240 clicks per video. At a 2% conversion rate, you're generating about 5 new paying referrals per upload. After twelve months of consistent monthly tutorials, you've got roughly 60 referrals in your base. If each generates an average of $3 per month in combined commissions, that's $180/month in pure recurring revenue — plus around $300 in first-order commissions throughout the year. Total first-year earnings: $2,000-2,500. That's the stage I'm at right now. Not flashy. Not quitting-my-job money. But real, trackable income from content I genuinely enjoyed making. # # # Scenario 3: The Established Creator (30K Newsletter Subs + 75K Blog Visitors) This is the dream stage. Two AI-related pieces of content per week. Established authority. Higher trust from your audience. Click-through rates of 2-3% and conversion rates hovering around 2-3%. You generate 15-25 new referrals per month, consistently. After one year, your referral base sits at 180-300 users. Average commission per user: $3-4 monthly. That's $540-1,200/month in recurring revenue alone, plus first-order commissions from each new signup. Annual earnings: $8,000-15,000. I haven't gotten here yet. But I'm building toward it, and I'll show the numbers when I do. # # The Compounding Magic Nobody Talks About Here's what makes recurring commissions feel almost unfair once you hit a certain threshold. Month 1: You get 5 new referrals. Total base: 5. Monthly recurring: $15. Month 6: You've added another 30 referrals. Total base: 35. Monthly recurring: $105. Month 12: Your base is 60+. Monthly recurring: $180+. Month 24: Even if you publish zero new content, your existing referral base keeps paying you. Assuming decent retention, you're still earning $150+/month from referrals who signed up two years ago. This is why I focus my affiliate energy almost exclusively on programs with recurring structures. One-time payouts are lottery tickets. Recurring is a slow-blooming annuity. The Global API program is one of the better recurring structures I've found because the 8% applies to a subscription people actually keep paying for, month after month, as long as they're using the service. # # Mistakes I Made (So You Don't Have To) Quick transparency on what didn't work for me: Mistake #1: Spreading too thin. I tried promoting eight different affiliate programs simultaneously. Clicks split across all of them meant none of them converted well. Focus beats diversification in the early stages. Mistake #2: Hiding affiliate links. I used to bury them in "Resources" sections hoping readers wouldn't notice. Once I started being upfront about it, my conversion rate actually improved. People respect honesty. Mistake #3: Chasing high-commission programs over good products. A 50% commission on a junk product converts terribly. Better to earn 8% on something your audience actually wants and keeps using. Mistake #4: Not building an email list. My newsletter is now my highest-converting channel. If you're not building one, start yesterday. # # My Actual Monthly Breakdown (Recent Quarter) Since I'm doing this build in public thing, here's my last three months in cold numbers:
23. Month 1: $312 (mostly first-order commissions from a viral blog post)
24. Month 2: $487 (recurring started kicking in + new referrals)
25. Month 3: $611 (almost entirely recurring from growing referral base) Total for the quarter: $1,410. Not life-changing. But it's the most reliable income stream I have that doesn't involve trading hours for dollars in real-time. And the trend line is going up, slowly but unmistakably. # # Final Thoughts: Why I'm Recommending Global API I've tried a lot of affiliate programs over the past year. Some had better commission rates on paper. Some had bigger brand recognition. But the Global API program is the one I keep coming back to for three specific reasons: First, the commission structure is genuinely generous. 15% on first orders plus 8% recurring is competitive in the space. The 10% premium tier commission is a nice bonus for anyone whose audience includes heavier users. Second, the product actually solves a real problem. Recommending something embarrassing is exhausting. Recommending something that legitimately helps your audience makes the content easier to write and the conversions easier to justify. Third, recurring revenue compounds. I've explained this twice already because it's that important. Subscription-based products pay you forever, not just once. If you've been thinking about adding a tech affiliate program to your income stack — whether you've got a small blog, a growing YouTube channel, or a newsletter with engaged readers — I'd genuinely recommend checking out the Global API affiliate program here: https://global-apis.com/affiliate?ref=devto-how-much-earn-ai-affiliate It's not a get-rich-quick scheme. It's not going to replace your salary overnight. But it's a legitimate, recurring income stream you can build in public, month by month, with full visibility into what's actually working. That's the whole point of this movement, isn't it? Showing the real numbers so we can all build smarter. If you end up joining, I'd love to hear how it goes. Drop your results in the comments. Or don't. Either way, keep building.
