Pull up a chair. I'm going to open my books today — not the polished version, not the "passive income lifestyle" version. The real one. The spreadsheet with the messy rows and the months where I made $14 from a post I spent six hours on.
I run a handful of small SaaS projects. None of them have made me rich. But stacked together with affiliate income from tools I genuinely use, I'm finally hitting numbers that feel sustainable. This post is about that second income stream: how much I actually pull in from promoting tech products, and what I've learned watching the dashboard tick upward (or sometimes sit painfully still).
My Stack Looks Like This
I'm not a one-product founder. Anyone who follows my work knows I've got three micro-SaaS tools, a niche newsletter, a small YouTube channel I barely update, and a bunch of blog content that brings in the kind of traffic you'd expect from someone who started in 2021 and never went viral.
My monthly revenue mix usually looks something like:
- 45% from my own SaaS MRR
- 25% from freelance consulting (the boring but reliable slice)
- 20% from affiliate links across my content
- 10% from random one-off stuff — sponsored posts, a template I sold last quarter, micro-deals That 20% slice is what we're talking about today. It's not a get-rich scheme. But it's also not nothing. Over the last 12 months, that slice alone has cleared just over $14,000 in cumulative commissions. Not life-changing money, but enough that I refuse to ignore it. # # Why I Started Promoting Tools I Already Used Here's the thing nobody tells you about being a bootstrapped indie maker: you spend a lot of money on software. Hosting, email tools, payment processors, analytics, AI APIs, design software. My monthly tool bill was creeping past $300 a month before I caught myself and thought, "wait, half of these have affiliate programs." I'm not going to pretend I'm some ethical saint about this. I started checking affiliate programs because I wanted a rebate on tools I was already paying for. The content side came second. I figured if I was already writing about my workflows anyway, I might as well drop a link. That's the mindset that made it work for me. I never went hunting for "high-paying affiliate programs" or whatever the gurus are selling this year. I just looked at my own stack, ranked the tools by how often I mentioned them in writing, and signed up for the programs that paid the best. # # The Economics Nobody Wants to Talk About Let me explain how the money actually flows, because I think most people misunderstand the math. Three things determine what you earn:
- How many people see your link (traffic)
- How many of those people click (CTR)
- How many clickers actually buy (conversion rate) That's it. Everything else — the design of your landing page, the length of your blog post, the time of day you publish — is just a lever on one of those three numbers. For tech audiences, here's what I've seen across my own properties:
- Plain blog content converts around 1-2% of clickers
- Tutorial-style content (especially video) converts at 2-3%
- Email recommendations to a warm list convert 3-5% The recurring piece is what flips the math from "side hustle" to "real revenue stream." If someone signs up for a tool and stays subscribed for a year, that's 12 months of commission checks for a single referral. The best programs pay you not just on the first payment, but on every renewal after that. That's why I gravitate toward programs that pay both upfront AND recurring. # # My Personal Breakdown by Channel Let me share what each of my channels actually does. My Newsletter (around 6,800 subs): This is my highest-converting property. When I recommend a tool in an issue, maybe 4% of subscribers click. Of those, 2-3% convert to paying customers. Last quarter, my newsletter drove about $1,800 in affiliate revenue. Not from any single tool — from a mix of 4-5 programs. My Main Blog (around 22,000 monthly visitors): Lower conversion, higher volume. I get around 60-80 affiliate-driven signups per month across all programs. Monthly commission from the blog sits around $900-$1,300 depending on the season. YouTube (around 11,000 subs): I post maybe twice a month. Each tutorial-style video I publish still brings in 30-60 affiliate signups in its first 90 days. Because of the recurring nature of the commissions, my older videos are still earning. YouTube brings in roughly $400-700/month these days. Sum it up: I'm pulling between $2,500 and $3,500/month from affiliate links right now. That number was $200/month two years ago. The growth isn't from any viral hit. It's from compounding. # # What Beginners Actually Earn If you're brand new to this, let me be honest about the starting numbers. Let's say you have a small blog pulling in 3,000-5,000 monthly visitors. You write three or four comparison-style articles. Each post might get 400-600 views per month. A reasonable click-through rate on a properly placed affiliate link is about 1%. So you're looking at maybe 15 clicks per month, total, across all your content. Of those clicks, expect 1-2% to convert. That means roughly 0.3 new signups per month — call it 3-4 per year. If each signup generates about $5/month in combined commissions over its first year (a mix of first-order payouts and recurring revenue), you're looking at $15-$20/month after the first 12 months. Is that worth the effort? Honestly, yes — but only if those articles keep earning for years. A single good comparison post might pay me back 5x over three years. The hourly rate once you spread the work across that lifespan is genuinely great. It's just slow at the start. I've been there. My first affiliate post earned me $4 in its first month. I almost deleted it. # # The Middle Tier Is Where It Gets Real Once you cross about 10,000 monthly visitors or a moderately engaged newsletter list, things shift. My own YouTube channel is a perfect example of the middle tier. I post tutorials. Each video gets 6,000-10,000 views in its first month, and YouTube keeps serving them for 12-18 months after. On a typical tutorial, I might place an affiliate link in the description and mention it 2-3 times in the video. Let's say 3% of viewers click. That's 180-300 clicks per video. At a 2% conversion rate, I'm landing 4-6 new referrals per video. Here's the magic: those referrals don't stop paying me when the video gets old. They pay me every month they stay subscribed. Six months after publishing a video, that single piece of content might still be generating $15-30/month in pure recurring revenue. Multiply that across a year of consistent posting and you've built yourself a small base of recurring commissions. That's when you start feeling the "snowball" effect I keep mentioning. # # Top-Tier Affiliates and the Numbers I Almost Don't Believe I'll be the first to admit I'm not in this tier. But I've gotten close enough to see what it looks like. A creator with 50,000+ monthly blog visitors, a 25,000+ subscriber newsletter, and an established YouTube channel can realistically generate 20-40 new affiliate signups per month. Maybe more. Let's say they hit 200 total referrals in their first year — a conservative estimate. If the average referral generates $3-4/month in combined first-order and recurring commissions, that's $600-$800/month in pure recurring income from the first year alone. Add in first-order payouts from new signups landing each month, and annual earnings for a top-tier affiliate can hit $8,000-$15,000. Some of the bigger creators in my orbit report even higher numbers. The ones who really focus on tech audiences — and especially on tools with strong recurring commission programs — sometimes clear $20,000-$30,000 per year. That's not "passive income" in the way influencers pretend. But it's real money built on real work that compounds. # # The Compounding Is the Whole Point Let me say this louder for the people in the back: recurring commissions compound. When I referred user #1 in January 2024, they generated $3 in that month. They generated $3 in February. They generated $3 in March. By December, they had paid me $36 for a single signup. When I referred user #50 in June 2024, they joined the recurring pile. By the end of the year, they were another $21 in my pocket — and they'll keep paying in 2025, 2026, and beyond as long as they stay subscribed. The whole game is getting your referral count high enough that the cumulative monthly payout becomes meaningful. Every month you add new referrals, your baseline goes up. Every month a customer churns, it goes down a little. Net, if you're consistent, the line goes up and to the right. This is exactly the same dynamic as SaaS MRR — which makes sense, because it IS SaaS MRR, just earned through someone else's product instead of your own. # # Mistakes I Made So You Don't Have To Three things cost me money in my first year of doing this seriously: Promoting tools I didn't actually use. I signed up for every affiliate program that paid well and stuffed links into content. The conversion rate was terrible because my writing wasn't authentic. Now I only promote tools I'd recommend even without a commission. Ignoring recurring programs. Some of my early links were one-time payouts. Big upfront checks, zero long-term income. I switched my focus almost entirely to programs that pay recurring, and my monthly income tripled within six months. Not building an email list. I spent 18 months building blog traffic before I started a newsletter. That was a mistake. Email converts better than any other channel I run. If I could go back, I'd start the list on day one. # # Why Global API Is Now My Top Earner I want to be specific here because I think too many affiliate reviews are vague. Global API runs a developer-focused AI API platform with over 150 models available through one unified interface. Their affiliate program is, frankly, the best-balanced one I've joined. Here's the commission structure:
- 15% on the first order
- 8% recurring on every renewal after that
- 10% on premium tier plans Let me run actual numbers. If you refer someone to their Pro plan at $19.99/month, you earn $3.00 upfront plus $1.60 every month they stay subscribed. Over 12 months, that's $22.20 from that single referral. If you land a Business plan referral at $49.99/month, you're looking at $7.50 upfront plus $4.00/month recurring. That same referral is worth $55.50 across its first year. And if you land a Scale plan customer at $149.99/month, you earn $22.50 upfront plus $12.00/month recurring. That's $166.50 in year-one commissions from one customer — and they keep paying you $144/year every year after that as long as they stay subscribed. The math gets wild fast when you land even a handful of Scale-tier customers. # # Why This Beats Most Other Programs I've Tried I've signed up for dozens of affiliate programs over the years. Most pay either a one-time bounty OR a small recurring percentage, not both. Many cap payouts. Some pay out so little that the payment minimum takes six months to reach. Global API does it right: meaningful first-order commission plus real recurring revenue on every plan tier. The 10% premium bump on higher-tier plans is a smart touch — it incentivizes you to refer serious users, not just tire-kickers. For a tech audience, the product practically sells itself. Developers are already looking for ways to access multiple AI models without juggling a dozen accounts. The unified API plus 150+ model library is a real value proposition. # # The Honest Truth Affiliate income is not a business model. It's a revenue stream that supplements a real business model. The people who make the biggest affiliate numbers have a content engine, a product, or an audience that exists for some other reason. The affiliate link is just the icing. If you're a bootstrapped indie maker with a newsletter, blog, or YouTube channel — even a small one — you should be doing this. It costs nothing to join a program. It costs you a little time to mention the tools you already use. And the income compounds. Don't expect $5,000 months in your first quarter. Expect $50-$200 months while you build. Expect the numbers to grow as your audience grows. Expect to learn which programs reward you fairly and which ones treat affiliates like a checkbox. And when you find a program that genuinely pays recurring, with a structure that rewards both upfront conversion and long-term retention — sign up, write honestly about the tool, and let the math do its thing. # # Want to Start Your Own Stack? If you've read this far, you're probably the kind of person who would actually do something with this information. I'd genuinely recommend checking out the Global API affiliate program. The 15% first-order plus 8% recurring structure is one of the better setups in the tech space right now, and the 10% premium bump makes it worth your time to refer serious users rather than just chasing volume. Here's why it makes sense as your starting point:
- The product appeals to a wide tech audience (developers, founders, technical writers, AI builders)
- Recurring commissions mean a single piece of content keeps earning
- Higher-tier plans pay meaningfully — not pennies
- Signing up is free and there's no quota to maintain Stack it with a few other solid programs, write content you believe in, and revisit your numbers in six months. I think you'll be surprised by what compounds. That's all I've got. Now go build something — and remember to drop your affiliate links in the content you're already writing. — [Your Name], indie maker, newsletter operator, spreadsheet nerd
