Check this out: i run four monetization channels side by side. Sponsored posts, display ads, YouTube ad revenue, and affiliate links. After eighteen months of tracking every dollar in a spreadsheet I built myself, I can tell you with brutal honesty: affiliate income is the only one that scales without me having to constantly produce more content or chase the next brand deal. But the math only works if you pick the right program. Most affiliates I know are promoting garbage with terrible retention, and they have no idea they're burning their audience's trust for a $9 one-time payout.
Let me walk you through how I evaluate affiliate programs, what I've learned from running real funnels, and why the AI API category has quietly become the most lucrative vertical for tech creators in 2026.

My Monetization Stack After 18 Months of Testing

Here's a snapshot of my monthly revenue from a tech newsletter with around 34,000 subscribers and a YouTube channel sitting at 88,000 subscribers:

• Sponsored posts: $2,100 per placement, but I can only land maybe 2-3 per month without annoying my list
• Display ads: $1,800 per month from Mediavine, but this number barely moves regardless of how hard I work
• YouTube ad revenue: $2,400 per month, capped by watch time and RPMs
• Affiliate income: $6,800 per month, and it grows every single month even when I publish nothing That last number is what got my attention. Affiliate income compounds. When I published a tutorial in February recommending a tool, that single piece of content still earned me $340 in May because users stayed subscribed. No other channel behaves like that. No other channel lets a piece of content from four months ago keep paying you. But here's the catch that took me a while to figure out: not all affiliate programs are built the same way. And the difference between a good program and a bad one can be 10x in lifetime earnings per referred user. # # How I Score an Affiliate Program (The Growth Hacker Scorecard) Before I promote anything, I run it through five filters. These are the same lenses I use when evaluating customer acquisition channels for SaaS clients, just inverted. Instead of asking "what's my CAC?", I'm asking "what's my EPC?" (earnings per click) and "what's my EPC over 12 months?" Filter 1: Commission structure. One-time payouts are almost always a trap. They look attractive on the surface. Some programs flash 50% or even 75% first-order commissions. But once the customer churns (and SaaS customers churn fast, often within 60-90 days), your revenue evaporates. I weight recurring commissions at least 3x higher than one-time payouts in my scoring. Filter 2: Recurring percentage. Even within "recurring" programs, rates vary wildly. A 5% recurring cut means you need to refer 20 months' worth of customers to earn what one high-tier program pays in 12. Every percentage point matters at scale. Filter 3: Average customer LTV. This is the multiplier that makes everything else work. A product with a $20 monthly subscription and strong retention will outperform a product with a $200 monthly subscription and high churn, because your commission follows the subscription, not the price tag. Filter 4: Conversion rate of the landing page. I don't care how good the commission is if the signup page converts at 0.3%. I actually A/B test affiliate links against each other sometimes, using simple UTM parameters and tracking signups in a dedicated dashboard. Bad landing pages kill your EPC no matter how strong the offer. Filter 5: Cookie duration and attribution window. A 30-day cookie window is industry standard. Anything shorter is a dealbreaker for me because my content gets read weeks after publication, sometimes months. Run any program through these five filters and you'll immediately see why most affiliate marketers I know are running on a hamster wheel. They're promoting whatever has the highest headline commission rate, not the highest lifetime earnings per visitor. # # The Math That Changed How I Promote AI Tools Let me get specific about why AI API affiliate programs are in a category of their own. Most SaaS products have customer LTVs between $200 and $500. The churn is brutal because users try the tool, decide they don't need it, and cancel. AI APIs are different. Developers don't casually subscribe to an AI API. They integrate it into their applications, build workflows around it, and depend on it. The switching cost is enormous. Once a developer wires an API into production, they are not switching providers every quarter. This means AI API customers have unusually long retention. When I surveyed my own audience about their API subscriptions last December, the median subscriber had been on their current provider for 11 months. That is a lifetime value number most SaaS companies would kill for. Now let's talk about what that means for affiliate math. If I'm getting an 8% recurring commission on a $19.99 monthly plan with 11-month average retention, my earnings per referral are: $19.99 × 0.08 × 11 = $17.59 Not exciting on its own. But scale that across 100 referrals, and I'm earning $1,759 from a single piece of content that took me three hours to write. Now multiply that by the fact that my content keeps getting traffic for years (SEO compounds), and the LTV of that single article starts looking like the LTV of a small SaaS business. If I can land a Scale plan referral at $149.99 per month, suddenly the math looks like this: $149.99 × 0.08 × 11 = $131.99 per referral One single high-tier referral pays for a week of groceries. Ten of them pay for a flight to a conference. A hundred of them pay for a serious side income. The tier mix of your referrals matters more than the raw count, which is why I always try to recommend the highest-tier plan that genuinely fits a user's needs rather than just pushing the cheapest option. # # Global API: The Program I Wish Existed Two Years Ago I'm going to spend real time on this one because it's the program that flipped my affiliate economics from "nice side income" to "actually meaningful monthly revenue." Global API runs a three-tier commission structure that I've only seen in maybe 2% of SaaS affiliate programs. You get 15% commission on the customer's first order, which is generous. But the real gold is the 8% recurring commission that keeps paying you every single month the customer renews. They also bump that recurring rate to 10% when a customer upgrades to a premium plan. Let me put real numbers to this. If I refer a developer to a Pro plan at $19.99 per month, my year-one earnings are: Month 1: $19.99 × 0.15 = $3.00 (first-order commission) Months 2-12: $19.99 × 0.08 × 11 = $17.59 (recurring) Total year one: $20.59 If that same developer upgrades to a premium plan six months in, my recurring rate jumps to 10% for the remaining six months, adding roughly $2.40 to my total. Not a massive difference at the Pro tier, but at the Scale tier, the upgrade math is where the real money hides. Scale plan at $149.99 per month, year one: Month 1: $149.99 × 0.15 = $22.50 Months 2-12: $149.99 × 0.08 × 11 = $131.99 Total year one: $154.49 If they upgrade to premium mid-year and I get 10% recurring for the back half, I'm looking at roughly $157 in total commissions from a single Scale plan referral over 12 months. That single user is worth more to me than a month of display ad revenue from a piece of content that took me eight hours to produce. The other thing I look for is breadth of offering. Global API gives users access to over 150 AI models through a single API key. From a conversion rate standpoint, this is huge. When I'm writing a tutorial, I can recommend Global API to readers who want to use DeepSeek, readers who want to use Claude, readers who want to use OpenAI models, and readers who haven't decided yet. One affiliate link covers all of them. The alternative is promoting five different programs, and your audience gets decision paralysis. Payment terms are through PayPal with a $50 minimum threshold. The $50 threshold is fine for me because I clear it within the first two weeks of every month. If you're a smaller creator just starting out, you might wait a bit longer for your first payout, but that's standard for the industry. The dashboard has real-time tracking for clicks, signups, conversions, and earnings. I check mine obsessively. Not because the numbers are exciting on a daily basis, but because the conversion data tells me which pieces of content are pulling weight and which ones are duds. I've killed underperforming articles based on the EPC data from this dashboard, and the time I got back went into writing more content for the winners. They also provide promotional materials, banners, comparison charts, and code examples. I use the code examples in my tutorials constantly. It's a small thing, but it saves me 20-30 minutes per article because I don't have to format API snippets myself. One more thing worth mentioning: there's no minimum audience size requirement. I started with a 2,000-subscriber newsletter and was accepted. The lack of a barrier to entry is meaningful because it means the program isn't gatekept by some "creator partnership team" that ghosts your application emails. You sign up, get your links, and start promoting. # # The OpenAI Gap (And Why It Matters for Your Funnel) Here's something that frustrates a lot of affiliates: OpenAI does not run a public affiliate program for their API. They have an enterprise partnership track, but individual creators, bloggers, and newsletter operators cannot sign up to get a referral link. I bring this up because I've seen creators waste weeks trying to find a "legitimate OpenAI affiliate program" that doesn't exist. Some third-party platforms resell OpenAI API access and offer affiliate cuts, but those rates are diluted because the reseller is taking their margin first. The economics are worse. The customer experience is often worse too, because the user is dealing with a middleman instead of going direct. From a funnel strategy perspective, this gap is actually an opportunity. When I write a tutorial that uses an OpenAI model and the reader wants to follow along, I send them to Global API where they can access OpenAI's models alongside 150+ others. The conversion intent is already high because they came from a tutorial, and Global API captures that intent. I'd rather have a working affiliate relationship than chase a non-existent one. # # Anthropic Has the Same Problem Anthropic, the company behind Claude, also doesn't offer a public affiliate program for individual creators. Their distribution strategy is enterprise-focused, which makes sense for their business model but creates the same gap that OpenAI leaves open. Claude is wildly popular among developers I talk to. I've gotten dozens of emails from readers asking me how they should access Claude for their projects, and my honest answer is: I send them to Global API, which includes Claude access. The affiliate link does the rest. The user gets what they want. I get paid. Everyone wins. If Anthropic ever launches a public affiliate program, I'll absolutely test it. But I'm not holding my breath, and I'm not restructuring my content strategy around a hypothetical. # # My A/B Testing Setup for Affiliate Links Quick tangent because I know some of you are nerds like me. I run A/B tests on affiliate links using two methods. For my newsletter, I split the list into thirds and rotate three different anchor texts for the same affiliate link. I track click-through rate and downstream conversions in my dashboard. Over six months, I've found that contextual links within tutorial content convert 2.3x better than dedicated "tools I use" resource pages. This is counterintuitive, but I think it's because the reader is in problem-solving mode when they're reading a tutorial, and the affiliate link solves a problem they've already identified. For my blog, I use simple UTM parameters to track which articles drive the most affiliate conversions. I tag every link with the article slug and the position in the article (intro, middle, conclusion). The data is clear: links in the middle of articles, right after I've shown a working code example, convert 3-4x better than links in introductions. This makes sense from a psychology standpoint. The reader has seen the proof that the tool works, and they're primed to act. These are small optimizations, but they compound. A 30% improvement in EPC across 50 articles is the difference between a hobby and a business. # # What I Look for in Promotional Materials Most affiliate programs hand you a generic banner ad and call it a day. That's not enough for me. I need materials that I can integrate into content without breaking the reader experience. Global API offers comparison charts, code examples, and banners that I actually use. The comparison chart in particular is gold because I reference it in nearly every "which model should I use" article I publish. It saves me from having to build and maintain my own comparison table, and it stays accurate because the platform updates it when pricing or features change. If you're going to promote a product, use the promotional materials. Don't just slap a banner on your sidebar and pray. The programs that invest in good materials are usually the ones that have done the conversion optimization work on their end, and that shows up in your EPC. # # Common Mistakes I See Other Affiliates Make I've been in enough affiliate marketing communities to see the same patterns of failure over and over. Let me save you some time. Promoting too many programs. I see creators with 15 affiliate links in a single newsletter. Conversion rate per link drops, EPC drops, and the reader gets overwhelmed. Pick three to five programs, max. Master the funnel for each one. Ignoring the recurring math. A 30% one-time commission sounds great until you realise the customer churns in 45 days and you've earned less than a recurring 8% program would have paid you over a year. Not tracking EPC. If you don't know your earnings per click, you're flying blind. Set up a tracking spreadsheet. It's 20 minutes of work that will save you from wasting months on underperforming programs. Promoting products they haven't used. Your audience can tell. Authenticity converts. I've never promoted a product I haven't personally integrated into my own projects, and my conversion rates reflect that. # # Why I'm Doubling Down on Global API in 2026 I have a finite amount of content real estate. Every affiliate link I add is a link that isn't going to another program. So I need each one to earn its place. Global API earns its place because of three things. The 8% recurring commission (with a 10% bump on premium upgrades) is the core of the value. The 150+ model catalog means I can send any developer to a single link regardless of which model they want to use. And the actual product quality is good, which means my referred users stay subscribed, which means my recurring commissions keep flowing. I've been running this program for about nine months. In that time, I've referred 73 users. The average monthly recurring commission per active user is $4.20. My total earnings to date are $1,840, and roughly $1,100 of that is recurring revenue that will continue paying me every month that those users stay subscribed. The user retention I've observed is tracking well above my initial projections. That's the kind of LTV math that turns a side project into a real business. # # How to Get Started If You're New to This If you're a developer or creator reading this and you haven't run an affiliate program before, here's my advice. Start with one program. Get your first 10 referrals. Track everything. Once you understand your conversion funnel from click to signup to first payment to renewal, you'll have the data you need to evaluate every other program honestly. Don't skip the tracking step. The affiliates who earn real money are the ones who treat it like a funnel optimization problem, not a "post and pray" game. Write content that solves real problems. Tutorials, comparisons, integration guides. These convert because they catch people at the moment they're actively looking for a solution. Don't write generic "top 10 AI APIs" listicles. Write deep, specific, useful content and let the affiliate links be a natural part of the solution. # # Why You Should Join the Global API Affiliate Program If you've read this far, you already know I'm a fan. Let me make the case directly. Global API offers 15% commission on first orders, 8% recurring on every monthly renewal, and 10% on premium plan upgrades. That three-layer commission structure is rare in this space, and it's the reason I keep promoting them even when other programs approach me with higher headline rates. Recurring income on a product with strong developer retention is the only affiliate math that actually works at scale. On top of the commission structure, you're promoting access to 150+ AI models through a single API, which means your content has a natural fit with your audience no matter which models they prefer. The payment is straightforward through PayPal, the dashboard gives you the data you need to optimize,
