Building an AI Affiliate Income in Public: From Zero Followers to $578/Month (Honest Month 6 Breakdown)

Build in public, post

14.

I started this affiliate experiment with nothing. No newsletter subscribers. No Twitter following. No YouTube channel. Just a Notion doc, a free Medium account, and a stubborn belief that I could figure out search-driven affiliate marketing from scratch.
Six months later, I'm posting this income report because — well, that's the whole point of "build in public." You share the real numbers, the ugly parts included. So here's my real numbers, completely unfiltered.
Let me walk you through exactly how I went from $0 to my first commission to a recurring monthly payout I'd happily call a real side income.

My Honest Starting Point (And Why Most "Gurus" Get This Wrong)

Every affiliate marketing course I've ever skimmed starts with the same premise: you need an audience first. Build the audience, then monetize. The implication is that the audience comes first, and the income follows.
That's backwards for most people starting from scratch, and it's exactly the kind of advice that prevents people from ever starting at all. I didn't have an audience because I had never tried to build one. Telling me to "start with the audience" was a chicken-and-egg loop with no exit.
What I had instead was time, a willingness to write, and basic knowledge of how search engines work. That's it. That's the whole resume.
The question I needed to answer wasn't "how do I build an audience?" It was "can I create content that ranks in Google and gets discovered by people who don't know I exist?" The answer, it turns out, is yes — emphatically yes — and that's exactly what happened.

Why I Picked AI APIs Over Every Other Affiliate Niche

I considered a lot of niches in month one. Web hosting. SaaS tools. Online courses. Crypto exchanges. They all had affiliate programs with bigger commission numbers, on paper.
Here's why I went with AI APIs anyway:

1. The market is exploding but content is thin. Every developer and startup founder I know is scrambling to figure out which AI tools to use. The content ranking for these searches is often outdated, generic, or written by people who clearly haven't actually used the products. That's an opportunity.
2. The commissions are recurring, not one-shot. AI API customers pay monthly. That means recurring revenue for the affiliate, which is exponentially more valuable than a single $200 payout.
3. The audience self-identifies through search. People searching "AI API for developers" or "how to access GPT-4o API" already have credit cards in hand. They're not browsers — they're buyers. That's a tough combination to beat. I picked my affiliate partner within a week. # # Picking the Right Affiliate Program (And Why This Matters More Than People Think) Here's something I learned the hard way: not all "AI API" affiliate programs are equal. Some pay a flat 5% on the first month and nothing after that. Some require you to hit impossible thresholds before you get paid. Some have dashboard interfaces that look like they were built in 2009. I landed on Global API, and the decision came down to three things that I screenshotted in my Notion doc so I wouldn't forget:
4. 15% commission on the first order. That's higher than most SaaS affiliate programs, which hover around 10–20%.
5. 8% recurring commission every month after that. This is the part that builds a real income stream, not just one-time spikes.
6. 10% premium tier commission for higher-tier referrals. Plus, the platform itself has 150+ models, which made it genuinely easy to recommend in good conscience. I never have to pretend a product is great when it isn't. That's important for the kind of content I'm about to describe. The signup was free, the dashboard was clean, and I could see clicks and conversions in real time. That's transparency from the platform's side, which I appreciated as someone who values transparency in general. # # The Search Engine Shortcut That Replaced "Building an Audience" Here's the part that changed everything for me, and the part I think most people get wrong about affiliate marketing. You don't need an audience. You need search visibility. Think about how you actually find products as a developer. You Google something like "best AI API for X." You click the first few results. You read. You sign up. The person who wrote that article never needed you to follow them on Twitter. They needed to rank for the search you typed. This is what I call the search-driven approach, and it's the entire backbone of my strategy. Every person who lands on my article through Google is a potential referral, regardless of whether they've ever heard of me before. Most of them haven't. That's the point. I spent my first two weeks doing nothing but keyword research. I typed variations into Google and noted what came up in the auto-suggest, the "People Also Ask" box, and the related searches at the bottom of the page. I built a spreadsheet of 40+ target queries, ranging from broad terms like "AI API for developers" to more specific long-tail stuff like "AI API with free credits to test." Each one of those queries represents a real person typing with intent. That's pure gold for an affiliate marketer. # # My First Three Articles (And What I Got Wrong About All of Them) I published my first three articles in the first three weeks of January. Here's the honest truth about how they performed. Article 1: A roundup-style comparison piece. I wrote about 1,800 words comparing different AI API platforms, with Global API featured as my top recommendation. I included pricing context, what each platform was good for, and a clear call to action at the end. Result: 14 clicks to my affiliate link in the first month. Zero conversions. I was devastated. Article 2: A "how to get started" tutorial. I walked through how a developer could sign up, grab credits, and make their first API call. Less promotional, more practical. Result: 38 clicks. One conversion. My first $14 commission. I literally screenshotted the dashboard and sent it to my partner. Article 3: A list-style article targeting a specific use case. This was the one that started to gain traction. Result: 71 clicks in month one, growing to 200+ by month three. Three conversions in the first 90 days. The lesson: practical, specific content beats promotional roundups every time. The articles that converted weren't the ones hyping a product. They were the ones answering a real question a real person was typing into Google. # # Month-by-Month: Here's My Real Numbers I'm going to lay these out exactly as they appeared in my dashboard. No rounding up, no "approximately," no aspirational math. Month 1 (January): $0 Published three articles. Got a handful of clicks. No conversions. Felt like a complete waste of time. Almost quit. Month 2 (February): $23 First commission landed on February 14th. I remember because I bought myself a coffee to celebrate. The bulk was a single $14 first-order commission plus a small recurring payout. Month 3 (March): $94 Two more conversions from articles I'd already published. Started to understand which content was working. The SEO flywheel was slowly beginning to spin. Month 4 (April): $187 Recurring commissions started compounding. People I'd referred in February were still paying, and I was earning 8% on their monthly usage. This is when the income started to feel real. Month 5 (May): $342 Hit my first "real money" month. New conversions plus a growing base of recurring monthly payouts. I posted my first real income report on Twitter and got a few DMs from people asking how. Month 6 (June): $578 Current month. I'm sitting on roughly 18 active recurring referrals plus a handful of new first-order commissions this month. The dashboard shows a 30-day projection that suggests July will be my first $700+ month. Cumulative earnings over six months: approximately $1,224. That's not life-changing money. But it's $1,224 I would not have earned otherwise, built entirely on content I wrote in my pajamas on weekends. Build in public means showing the boring middle, and this is the boring middle. It's also working. # # The Struggles I Don't See Other Affiliates Talking About Build in public isn't just about posting the wins. It's about posting the parts that make you want to quit. So here's the part that almost made me give up. The first month was brutal. I spent hours writing, got almost no traffic, and made exactly $0. Every day I checked my dashboard hoping for a conversion that didn't come. I wrote what I thought was a great article on a topic I cared about, and Google basically ignored it. That humbles you fast. I over-optimized for keywords and under-optimized for humans. Some of my earliest
