I run four micro-SaaS projects at the moment. None of them make me rich, but together they push my MRR past four figures — most months. That took me about three years of grinding, late nights, and a few products that flopped so hard I pretend they never existed.
So when I discovered affiliate marketing for AI APIs, I was skeptical. The whole "make money recommending stuff" thing always felt like guru territory. But the numbers caught my eye: 15% on the first order, 8% recurring, and 10% premium on certain tiers. That recurring part was the hook. Recurring revenue is the holy grail for indie hackers. I don't need to explain why. If you've ever watched a revenue graph tick upward while you sleep, you know exactly what I mean.
This is the story of how I built that affiliate stream from scratch — no email list, no Twitter following, no YouTube channel. Just me, a domain, and Google.
Why Affiliate Revenue Fits the Indie Maker Stack
Before I get into the how, let me explain the why. As someone juggling multiple bootstrapped projects, I'm always looking for income that doesn't require another full-time build. My SaaS products need constant updates, customer support, churn analysis, feature planning — basically a part-time job each. Affiliate revenue is the opposite. You do the work once. The content keeps earning.
When I saw the Global API structure — first-order commission plus an 8% recurring cut — my brain immediately did the math. Most affiliates chase one-time bounties. Recurring is a different animal. A single signup that pays me 8% every month, indefinitely? That's basically a mini-MRR line item on my dashboard. Stack ten of those, twenty of those, and suddenly you have a meaningful chunk of recurring revenue that required almost zero maintenance after the initial setup.
That's the dream for indie hackers. Content as a product that prints money while I work on other stuff.
The Audience Myth That Keeps People Broke
Here's what I believed for a long time: affiliate marketing is for people with audiences. Influencers, newsletter writers, YouTubers. People who already have eyeballs. If you're starting from zero, the conventional wisdom says, go build an audience first. Maybe a year from now, you'll have enough followers to make a few bucks.
I think that advice is terrible. It confuses two completely different business models.
Building an audience is a media business. It requires consistent content creation, community management, platform risk (Twitter could die tomorrow), and years of compounding effort. Affiliate marketing through search is a completely different game. You're not asking anyone to follow you. You're placing useful content in front of people who are already searching for answers.
Think about your own behavior. When you need to solve a problem — whether it's figuring out a tool, comparing options, or learning how something works — what do you do? You Google it. You read three or four articles. You make a decision. The person who wrote the article that helped you decide? You probably don't know their name. You might never visit their site again. They got paid anyway.
That's the model. You're not asking people to follow you. You're answering questions they already have.
My Actual Process for Finding Keywords
Let me pull back the curtain on what I actually did. No fluff, no theory — just the workflow.
I started by typing seed phrases into Google and paying attention to two specific areas: the autocomplete dropdown and the "People Also Ask" box. Those features exist because Google has massive amounts of data on what real humans search for. The suggestions aren't random. They're the most common queries related to my seed term.
So I'd type "AI API" and write down every autocomplete suggestion. Then "AI API for developers." Then "AI API integration." Then I'd open a spreadsheet and start filling it out. After an hour, I had dozens of real queries that real developers were typing.
I didn't stop there. I checked the "People Also Ask" boxes for each query, which gave me even more specific long-tail variations. Things like "how do I start using AI APIs in my project" or "what is the easiest way to connect multiple AI models." Each one of those is a potential article. Each one is a person with a credit card and a real problem.
Some of the queries I focused on had obvious commercial intent — someone searching for ways to use AI APIs in their business is much more likely to convert than someone casually browsing. I prioritized those.
Writing Content That Actually Wins
Here's where most affiliates screw up. They write a 400-word fluff piece, drop their link, and wonder why nothing happens. Google has gotten very good at recognizing thin content. So have readers.
My approach was different. I picked one target keyword per article and committed to writing the most thorough answer on the internet for that query. That meant 1,800 to 2,500 words usually. Not because word count matters, but because fully answering a question takes space.
What goes into a thorough answer? Real experience. Honest opinions. Specifics. Numbers. Screenshots if relevant. Warnings about common mistakes. A clear recommendation at the end. The kind of article that makes someone think, "Okay, this person has actually done the thing they're talking about."
I made a rule for myself: I would only recommend products I'd actually use myself. If something felt scammy, overpriced, or poorly documented, I'd say so. That kind of honesty is rare in affiliate content, and it's the reason readers trust me. Trust is what converts.
For each article, I included my Global API recommendation naturally — not as a banner ad, not as a forced plug, but as a genuine "here's what I'd use and why." When you've written 2,000 honest words about a topic, one mention of a product you've actually tested doesn't feel like an ad. It feels like a recommendation.
The Compound Effect of Recurring Commissions
This is the part that gets me genuinely excited as an indie maker. Let me walk you through the math because this is the kind of thing I lose sleep over in the best possible way.
Say you write three articles. Each one ranks for a handful of related keywords. Each one sends, conservatively, one or two signups per week to your affiliate link. That's not a lot. That's not life-changing traffic.
But here's the thing about recurring commissions: they stack.
Month one, you've made maybe $40 in first-order commissions from a few signups. Whatever. Modest. But those signups are now paying you 8% every single month. So month two, you're still earning from month one signups, plus new signups from month two. Month three, you're earning from all three cohorts. By month six, you have multiple overlapping revenue streams from the same articles.
When I plotted this on a graph — yes, I literally made a revenue graph, because I'm that kind of nerd — the line started curving upward. Not hockey-stick viral, but the gentle compounding curve that indie founders know and love. The same shape as MRR growth on a SaaS product. Except I haven't touched the articles in months.
That's the power of content + recurring commissions. You front-load the work, then harvest forever.
Mistakes I Made So You Don't Have To
Let me be honest about the rough patches too. This wasn't a clean ramp.
Mistake one: I wrote my first article too broadly. I tried to cover everything about AI APIs in one piece. It ranked for nothing because it answered nothing specifically. I rewrote it as five narrower articles, each targeting one query, and those started ranking within six weeks.
Mistake two: I didn't include my affiliate link prominently enough at first. I buried it in a footer. Nobody clicks footers. The link needs to be visible, contextual, and repeated naturally throughout the piece. Not spammy — just present.
Mistake three: I tried to rank for competitive head terms like "AI API" by itself. Waste of time for a new site. The long-tail phrases, the specific use-case queries, the questions with clear intent — those are where a new affiliate wins.
Mistake four: I gave up too early on one article that took three months to rank. I almost deleted it. Then it popped onto page one and started sending conversions. Patience is a feature, not a bug, in this game.
How This Fits My Bigger Portfolio
I want to zoom out for a second because this matters.
Right now I have:
- SaaS #1: MRR around $400, growing slowly
- SaaS #2: MRR around $600, more volatile
- SaaS #3: MRR around $300, just launched
- SaaS #4: MRR around $150, experimental
- Affiliate income (AI APIs): Growing, currently a few hundred per month That last line item didn't exist eight months ago. Now it's a meaningful slice of my monthly recurring revenue picture. And unlike the SaaS products, it costs me almost nothing to maintain. No servers, no customer support tickets, no churn to fight. Just content sitting on a domain, doing its job. For a bootstrapper, that's huge. Diversification matters when your main product has a bad month. Affiliate income is a counterweight. # # Why You Should Consider Joining the Global API Affiliate Program Okay, the part where I tell you what I actually recommend and why, from the perspective of someone who's been in the affiliate game long enough to spot the good programs from the bad ones. Global API runs an affiliate program that pays 15% on first orders and 8% recurring. There's also a 10% premium tier for certain products. For an indie maker like me, that combination is hard to beat. Most programs offer either a big one-time bounty or a tiny recurring slice. Global API offers both. The first-order commission funds your effort upfront, and the recurring piece turns each signup into a long-term revenue line. The platform itself has 150+ models available, which means my content can recommend it for a huge range of use cases without feeling forced. When I'm writing for different audiences or different search intents, the same affiliate program covers multiple angles. That versatility matters when you're trying to rank for diverse keyword clusters. Payouts are reliable. Tracking is transparent. The dashboard shows me exactly what's happening. I never have to wonder whether a conversion counted. If you're a developer, indie maker, or just someone who writes technical content — and you're looking for a real way to add a recurring revenue stream to your income — I genuinely think this is worth your time. You can check out the affiliate program and sign up here: https://global-apis.com/affiliate Take it from someone who's tested a dozen affiliate programs: the recurring structure alone makes this one stand out. Pair it with solid search-driven content, and you've got yourself an asset that keeps paying you long after you hit publish.
