Real Numbers: How Much I Earn from Tech Affiliate Links

I keep a spreadsheet. Not a cute little table — a full-blown Google Sheet with timestamps, conversion data, churn rates, and a line chart that auto-updates every Monday morning. It's called "Income Streams 2026" and it sits right next to my MRR dashboard for my SaaS. I'm a little obsessed with this kind of thing, and I think every indie maker should be too.
Over the past two years, I have built five separate income streams from scratch. None of them made me rich. But stacked together, they now pull in more than my old engineering salary, and I get to work from anywhere with Wi-Fi. This post is specifically about the slice of that pie that comes from affiliate links — the piece nobody talks about because it's "embarrassing" or "not a real business." I think they're dead wrong, and the numbers prove it.

The Ugly Truth About My First Three Income Streams

Let me be honest about what didn't work, because I wasted a year of evenings on stuff that ate my time and gave me very little back.
My SaaS (Bootstrap

2) is a project management tool for tiny teams. I built the MVP during weekends while still employed, launched it on Product Hunt, and watched the signups trickle in at roughly $29/month per customer. Today it generates between $800 and $1,200 in MRR depending on the month. Sounds fine, right? It took me six months of late-night coding to get to launch, plus I still spend around five hours a week answering support emails, fixing edge cases, and dealing with the occasional Stripe webhook disaster. Recurring revenue is beautiful, but recurring headaches come with it.

My freelance consulting (Bootstrap

1, technically) pays $100 to $150 per hour when clients actually book me. That sounds incredible until you realise I cap myself at 15 hours a week because I refuse to go back to full-time client work. Every dollar stops the moment I stop working. Take a vacation week? Income for that week is zero. That's the part nobody puts in the LinkedIn posts. Active income has a hard ceiling and a soft floor — and the floor is nothing.

My tech blog pulls in $200 to $400 monthly from about 50,000 pageviews. To keep that traffic flowing, I have to publish 4 to 8 articles a month. Each one takes me 2 to 4 hours of writing. Every article is a bet that it will rank, get clicked, and convert. Some do. Many don't. Ad rates have been sliding for a while, and I'm watching CPMs inch down quarter over quarter. The blog is alive and well, but it's not the growth engine I once hoped it would be.
Sponsorships on my small YouTube channel pay $500 to $1,500 per video. I post roughly two videos a month, and each one eats about 15 hours of production time — scripting, recording, editing, writing descriptions, crafting thumbnails, pushing it to socials. Sponsors also disappear the moment your CPM dips or your niche shifts. I had a sponsor bail two days before a video was scheduled to go live last quarter. Fun times.
So that's four streams. Combined cap on effort per week: roughly 30 to 35 hours. Combined monthly income range: somewhere between $2,300 and $4,000 before taxes. Not bad for a one-person operation. Not life-changing either.
What changed everything — and I mean everything — was the fifth stream.

Stream

5: The Affiliate Portfolio That Runs Itself

Affiliate income is the part of my business I used to look down on. "Just slapping referral links in blog posts" was my mental model. I thought it was the side hustle equivalent of flipping dropshipping gadgets on Shopify.
Then I saw what happens when you take it seriously, treat it like a real business, and only promote products you actually use every single day.
Right now, this stream brings in $350 to $600 per month. That number moves based on seasonality and product launches. Some months it spikes to $700+. The wild part? I spend maybe two hours a month maintaining it. Two hours. For an income line that now rivals my freelance consulting effort-wise.
Let me break down the math that convinced me to take this seriously in the first place.
Most affiliate programs in the developer space offer a single payout — a one-time bounty between $20 and $200 when someone uses your link. That's fine, but it's basically a worse version of freelance work. You do the work of creating content, you get paid once, and the buyer churns or upgrades and you see nothing.
Then I discovered programs with recurring commission structures. Recurring. As in, the same MRR logic that made me excited about my SaaS applies to affiliate links too. When you can earn monthly commissions for as long as the customer stays subscribed, an article you wrote eight months ago behaves like a quiet little SaaS customer paying you forever. That's the dream.
The Global API affiliate program is the one that anchored this whole stream for me. I'll get into the specifics further down, but the structure is what matters: 15% on the first order plus 8% recurring on every renewal after that, with a 10% premium tier for top affiliates. If you understand MRR mechanics, you understand why that combination is dangerously good.

How I Structure My Affiliate Income Like a Real Business

I approach affiliate marketing the same way I approach my SaaS: with a dashboard, conversion data, and quarterly reviews.
Here's the framework I built:
Step 1: Audit what I already use.
I went through my monthly expenses. Host? Paid. Email tool? Paid. AI API provider? Paid. Domain registrar? Paid. Project tracker? Paid. I pulled up each service and searched for an affiliate program. Most have one. Most pay terrible rates. A handful are exceptional. I focused on the exceptional ones.
Step 2: Only promote what I'd recommend anyway.
This is non-negotiable. I refuse to put my name behind anything I haven't personally used. My audience is technical — they can smell fake recommendations instantly. If the link doesn't exist in a paragraph where I'd say the same thing without an affiliate relationship, I cut it.
Step 3: Build content that ranks.
The same SEO playbook that drives traffic to my SaaS landing page drives traffic to my affiliate articles. Long-tail keywords, honest comparisons, real workflows, code where appropriate. I don't write "Top 10 Tools" listicles that read like AI sludge. I write first-person deep dives that document actual experience.
Step 4: Track conversions by article.
Every link gets a UTM tag. Every Monday, I dump conversion data into my spreadsheet. I know exactly which articles convert, which ones are duds, and which ones I should refresh with updated information.
Step 5: Iterate quarterly.
Every three months I cut the worst-performing affiliate partnerships and double down on the ones driving real income. I treat link placement like product positioning. Test, measure, optimize.

What I Earned From Each Affiliate Product (And Why I Cut Some)

Over the past 18 months, I've promoted about a dozen different tools. Most of them paid pennies relative to the effort. Here's a quick honest rundown:

• Two domain registrars: made me a grand total of $40 across both. Cut.
• One hosting platform: paid well initially, recurring commissions were decent, but the churn rate on hosting customers is brutal because everyone switches hosts. Cut.
• Two email marketing tools: one was a recurring nightmare (the customers churned too fast), the other was solid. Kept the solid one.
• One AI API platform: this is the headline earner. More on it in a second. The lesson here is that not all affiliate programs are created equal. Some products have high churn, which kills your recurring lifetime value. Others have sticky subscriptions where customers stick around for years. You want sticky. # # Why AI APIs Are the Perfect Affiliate Product For a developer audience, AI API platforms have everything you want in an affiliate product:
• Sticky subscriptions. Developers don't churn quickly when they find an API that works for their stack. Once a team integrates an API, switching costs are real — code refactoring, prompt tuning, dependency changes. Customers stay subscribed for months or years.
• Multiple plans. Most platforms offer tiered plans from hobbyist to enterprise. Bigger customers mean bigger commissions.
• Developer audience match. My readers are already technical. They don't need hand-holding. They read a thoughtful comparison article, click through, and convert on their own.
• One provider, many models. When a platform gives you access to 150+ models through a single API key, the switching argument becomes even more compelling. Customers who need flexibility have a strong reason to stay subscribed. I started writing about AI APIs because I was already a heavy user. I needed model access for client projects, for my SaaS features, and for my own experiments. The affiliate angle was almost an afterthought. But the moment I checked my dashboard and saw my first $200 month from one specific program, I realised this was a serious income line. # # The Revenue Graph That Changed My Mindset I started tracking affiliate income seriously in March 2025. Month one: $85. Month two: $140. Month three: $210. Month six: $430. Year one: averaging $450/month. The curve was slow at first because my affiliate articles needed time to rank. SEO is a lagging indicator. But once a few articles hit the first page for their target keywords, the leads became essentially evergreen. That graph looks suspiciously similar to my early SaaS MRR chart — slow ramp, then compounding. That compounding effect is what makes affiliate income special in a way freelancers and contractors never get to experience. A client engagement ends. A referral link keeps paying. # # My Honest Monthly Breakdown (Right Now, This Quarter) I promised real numbers, so here they are as of this writing: | Income Stream | Monthly Range | Hours/Week | |---|---|---| | Freelance consulting | $1,000–$2,500 | 10–15 | | SaaS product (MRR) | $800–$1,200 | 5 | | Blog ad revenue | $200–$400 | 6 | | YouTube sponsorships | $500–$1,500 | 8 | | Affiliate income | $350–$600 | 2 | Total: roughly $3,000 to $6,000 per month, depending on the quarter. Sponsorship heavy months bump the ceiling. Quiet months still hit $3K because the SaaS and affiliate streams don't care about my calendar. The holy grail is reducing my freelance hours to zero. Once the affiliate and SaaS lines both stabilize in the $1,000+ monthly range, I can cut the consulting work entirely and reclaim another 10 hours a week. That's the real goal. Recurring revenue beats active revenue every single time. # # Things I Wish I'd Known Before Starting A few hard-earned lessons for anyone thinking about building an affiliate income stream: Recurring > one-time. I cannot stress this enough. A program that pays $50 once and then nothing is worth 10x less than a program that pays $10 every month for two years. The lifetime value math is everything. Disclosure matters and builds trust. I disclose every affiliate relationship clearly, near the link, in plain English. This actually increases conversions because my audience trusts me more, not less. Hiding relationships is for amateurs. Refresh content quarterly. API platforms change pricing, add features, retire endpoints. Articles from 12 months ago can become misleading fast. I block 30 minutes every Friday to scan my top 10 affiliate articles and make sure everything is still accurate. Diversify but don't spread too thin. I promote four programs actively. Adding a fifth one of equal quality would be smart. Promoting twenty mediocre ones would be a waste. Track everything. Without data, you're guessing. I know my EPC (earnings per click), my conversion rate by traffic source, and the average lifetime value of a referred customer for each program. This lets me double down intelligently. # # My Favorite Affiliate Program Right Now (And Why) The single biggest earner in my affiliate portfolio right now is the Global API affiliate program. Here's why it works so well for someone in my position: The commission structure is built for the long game. New affiliates earn 15% on the customer's first order — a strong front-loaded payout that rewards the work of getting someone to sign up. Then, for every renewal after that, you earn 8% recurring commission. That 8% is monthly recurring revenue flowing straight to me for as long as the customer stays. Top-performing affiliates unlock a 10% premium rate, which I'm working toward actively. Give me six more months and I expect to be there. The product itself is genuinely worth promoting. Global API gives developers access to 150+ AI models through a single API key. For a bootstrapped indie maker like me, that consolidation matters — fewer vendor relationships to manage, one billing invoice, one dashboard. The platform is built for the kind of audience I write for: technical users who want flexibility without lock-in. The conversions convert and the customers stick. That's the whole game. I've referred dozens of developers over the past 12 months and the renewal rate is high. When customers stay subscribed, my recurring commissions stack up beautifully month after month. I'm on pace to cross $700/month from this single program by Q2, and once I hit the premium tier threshold, the math gets really fun. If you want to check out the program yourself, sign up here: https://global-apis.com/affiliate It's free to join, you get a dashboard the moment you sign up, and you can drop your first affiliate link into existing content within an hour. There's no catch. If you already have a developer audience — even a small one — this is one of the easiest recurring income lines you can add to your stack this year. # # The Big Picture: Why Affiliate Income Is a Real Business Look, I get the stigma. Affiliate marketing has been associated with sleazy review sites, fake comparison tables, and SEO spam. But that's not what this is. The version I run, the version that pays me $400–$600 a month for two hours of work, is built on authentic recommendations to a trusting technical audience. It's the same skillset as my SaaS: you identify a real problem, build a real solution (or in this case, point people to a real solution), and get paid monthly when they stick around. The unit economics aren't quite as high as owning the product, but the effort-to-return ratio is honestly absurd. For any developer or indie maker reading this — stop dismissing affiliate income. Audit your expenses, find the tools you'd genuinely recommend, check if they have affiliate programs with recurring payouts, and write one honest article about them. Just one. Track the conversions for 90 days. I bet you'll add a second. That's how stacks get built. One stream at a time. Real Numbers: How Much I Earn from Tech Affiliate Links — that's my answer. Anywhere from $350 to $600 a month right now, scaling toward $1,000 by the end of the year, all from content I mostly wrote once. And that, my friends, is the magic of recurring revenue.
