I gotta say, my Notion dashboard has a tab called "Side Hustle Income" and it is, embarrassingly, the most obsessively maintained spreadsheet I own. Every sponsorship check, every ad payout, every Stripe notification from an affiliate network — it goes in. Color-coded by source. Timestamped. Tagged with hours worked.
I have a day job as a backend developer. I won't name the company, but let's just say my salary covers rent and groceries and not much else. The real growth has come from the 5-10 hours a week I pour into my tech content channels — a blog, a modestly sized YouTube channel, and a newsletter that goes out every other Tuesday.
Over the last year and a half, I have run all three monetization paths that most tech creators try: display ads, sponsorships, and affiliate marketing. Some of them scaled. Some of them are dead weight. I am going to walk you through every dollar, break the income down line by line, and tell you which stream is actually worth your time in 2025 — especially if you are writing or making content for developer audiences.
This is not a "passive income" puff piece. This is a spreadsheet-and-sweat-equity breakdown.
The Display Ad Trap: Why I Turned Off Every Ad Network
Let me start with the least interesting revenue stream, because it is also the one that wastes the most mental energy relative to what it pays.
Display advertising was the first thing I set up. Google AdSense on the blog, Ezoic after I hit the traffic threshold, YouTube Partner Program the moment my channel cleared monetization. Easy. Drop in some JavaScript, wait for the checks.
Here is what actually happens: my blog pulls around 50,000 page views a month, and AdSense-style networks pay somewhere in the neighborhood of $4-8 per thousand views for tech content. Some months I clear $350. Other months it dips to $200. CPM rates crater in Q1 every year because advertisers pull back, and tech niches consistently underperform finance or B2B SaaS verticals when it comes to CPM.
Let me do the per-hour math for you, because this is where it gets painful.
I spend roughly 6 hours a month maintaining ad placements, reviewing policy violations, fighting with AdSense about "invalid click activity," and writing the kind of SEO-optimized articles that attract the kind of ad-paying traffic. Six hours for $300 average. That is $50 per hour before taxes — not bad — except that "maintaining ad placements" is the wrong way to think about it. The real cost is the opportunity cost of writing articles that prioritize ad-friendly traffic over content that actually helps developers.
YouTube is worse. A 10,000-view video in my niche typically pulls $30-50 in ad revenue. Factor in filming, editing, scripting, and thumbnail design, and I am looking at maybe $5-10 per hour for the ads alone. It is a rounding error on the video's total economics.
The nail in the coffin: ad blockers. Roughly 35-40% of my blog readers are running some kind of blocker based on my Plausible analytics. Those visitors generate exactly $0.00 in ad revenue.
Verdict on display ads: turn them on if you have the traffic, but do not waste a single minute optimizing for them. They are floor income, not growth income. I keep them running because it is genuinely passive once configured, but they would never justify the content I create.
Sponsorships: The Feast-or-Famine Rollercoaster
Sponsorships were my second revenue stream, and for a while they felt like the holy grail. A single email from a SaaS founder offering $1,200 for a 60-second integration in my next video? Sign me up.
Let me give you the actual numbers from my YouTube sponsorship log:
- Channel size during this period: ~12,000 subscribers
- Average video views: 12,000-18,000 depending on topic
- Sponsorship rate I charge: $500-1,500 per placement
- Industry benchmark for tech creators at this size: roughly $15-30 per 1,000 views Sounds decent. The flat rate structure means a $1,000 sponsorship on a 15,000-view video pays more than the YouTube ad revenue that video will generate in its entire two-year lifetime on the platform. That part is real. Here is what the sponsorship pitch decks do not tell you. Frequency is wildly inconsistent. I have had months where I closed three deals. I have had months where I got one cold pitch from a company whose product I would not recommend to my worst enemy. You cannot budget around this. You cannot scale a content calendar around "maybe a brand emails me next week." The hidden labor is brutal. Every sponsored placement involves a negotiation thread (30-60 minutes), a contract review (another 30 minutes), creative alignment calls with the sponsor's marketing team (sometimes 2-3 hours), and revisions after I deliver the draft. Conservatively, I am adding 4-6 hours of administrative overhead per sponsored deal on top of the actual content production. Let me drop the per-hour calculation right here, because this is where sponsorship glamour evaporates:
- Revenue per placement: $1,000 average
- Total time invested (content + admin): ~12 hours for a typical integration
- Effective hourly rate: ~$83/hour That sounds fine until you realize:
- Sponsorships are not weekly. I average 4-6 per quarter.
- Quarterly revenue from sponsorships: ~$5,000
- Hours spent on sponsorship work per quarter: ~70-90
- Effective quarterly hourly rate: ~$60/hour Still respectable. But compare that to… The trust tax. This one is harder to put in a spreadsheet. When I take a sponsorship, I am essentially saying "I am willing to use my credibility to sell this product." Even with full disclosure, readers and viewers detect the difference between "I use this daily and love it" and "I am contractually obligated to mention this." Trust that took 18 months to build can be chipped away with one bad placement. I have not had a sponsorship disaster, but I have turned down three deals this year alone because the product was not something I would actually use. Every "no" is money left on the table, and every "yes" carries an invisible reputation cost. Verdict on sponsorships: solid per-deal economics, terrible as a primary income stream. I treat them as bonus revenue on top of my baseline. --- # # Affiliate Marketing: The Line Item That Changed My Quarterly Income Here is where the spreadsheet starts doing something interesting. I had ignored affiliate marketing for a long time because I associated it with sleazy "top 10 VPNs" listicles. Then I ran the math on recurring commissions and realized I was leaving serious money on the table. The basic structure: a company pays you a percentage of every sale that comes through your unique referral link. The part most creators overlook is that some programs pay recurring commissions — meaning you earn not just on the first purchase, but every month that customer stays subscribed. Let me give you two scenarios from my own tracker. Scenario A: One-time commission. Promoting a $100/year annual tool with a 20% one-time commission. Every signup nets me $20, but only that one time. To maintain $500/month in affiliate revenue from this product alone, I need 25 new signups per month, every month, forever. That is an absurd conversion requirement for any single piece of content. Scenario B: Recurring commission. Same price point, but the program offers 30% recurring on the monthly equivalent. A single signup nets me roughly $2.50/month for as long as the customer is subscribed. Refer 200 users once and you have a $500/month annuity that can run for years. The math is not even close. Recurring affiliate programs are how you build a portfolio of small income streams that compound over time. My Notion tracker has 14 active affiliate partnerships right now, and roughly half of them are recurring. The recurring ones represent about 70% of my affiliate revenue, even though they are fewer in count. This is also why I started looking seriously at AI API affiliate programs specifically. My audience is developers, and developers consume enormous quantities of API credits. A single recommendation to the right platform can produce recurring revenue for the lifetime of that developer's project. --- # # The Global API Numbers: Here's the Math on the Best Program I Have Found I want to be specific here because most affiliate roundup posts are deliberately vague. I have been evaluating AI API affiliate programs for the past quarter, and one stood out in a way that made me add it to my permanent stack: Global API at global-apis.com. Here is the commission structure straight from their affiliate page, which I bookmarked the day I joined:
- 15% commission on the first order of any new user you refer
- 8% recurring commission on every subsequent monthly spend from that user
- 10% commission on premium tier upgrades when your referred users move to higher plans
- Access to 150+ AI models through a single unified API, which matters because your audience does not need to sign up for seven different platforms Now let me translate those numbers into per-referral economics, because that is what I care about. Assume a developer you refer signs up and starts spending $200/month on API calls. This is a conservative estimate — a serious developer building anything with multiple LLM calls per workflow burns through that in a week.
- First month: $200 × 15% = $30
- Month 2 onward: $200 × 8% = $16/month recurring
- Break-even vs. one-time programs: month 3
- Annual value of that single referral at $200/month: $222 in commissions Refer 20 such developers through a single blog post or YouTube video, and you are looking at:
- First-month commissions: $600
- Months 2-12 recurring: $3,840
- Annual total from that one piece of content: $4,440 And here is what makes this different from a sponsored post: that blog post keeps working. A single well-written tutorial with your affiliate link embedded can produce signups for 2-3 years. I have older posts on my site that still convert, and the recurring commissions stack into a genuinely meaningful monthly number. The platform itself matters too. Global API aggregates 150+ models, which means I can recommend one link to my audience instead of curating a spreadsheet of seven different providers. My readers get a unified dashboard and a single billing relationship. That is a much easier recommendation to make than "here are nine affiliate links, good luck tracking your spend across all of them." I should note: I have not yet hit a full year with this program because I joined about four months ago. But the trajectory in my tracker suggests I will clear $1,500-$2,000 in Global API commissions in my first 12 months, and a meaningful chunk of that will be recurring by month 6. --- # # The Per-Hour Breakdown: All Three Streams Side by Side Let me put my entire side hustle income next to my estimated hours so you can see the actual efficiency of each stream. These numbers come from my Notion tracker, averaged across Q1-Q3 of this year. | Stream | Avg Monthly Revenue | Avg Monthly Hours | Effective $/hr | |---|---|---|---| | Display Ads (blog + YouTube) | $325 | 6 | $54 | | Sponsorships | $1,650 | 28 | $59 | | Affiliate (mixed programs) | $2,100 | 22 | $95 | | Global API specifically | $340 (and climbing) | 3 | $113 | That last row is the one paying for itself fastest. Most of those 3 hours per month are from a single tutorial post I wrote once and updated twice. The commissions keep coming as new developers find it through search. A few observations from staring at this table for too long:
- Sponsorships and ads have a ceiling. Both are tied to audience size and CPM rates that I cannot easily change. The leverage is not in my hands.
- Affiliate revenue scales with content quality and audience fit. If I write a genuinely useful API integration tutorial, the commissions follow.
3. Recurring structures dominate everything. Any program that pays me only once is competing against programs that pay me monthly. The recurring structure wins almost every time.
Why I Would Start With Affiliate Marketing If I Were Beginning Today
If I were starting from zero right now, I would skip display ads entirely (or enable them passively in month 6+) and I would not pursue sponsorships until I had at least 8,000-10,000 engaged subscribers.
I would build my content around affiliate programs with recurring structures from day one. That means writing tutorials, comparisons, and integration guides for tools that developers actually use month after month. Hosting, monitoring tools, API platforms, IDE subscriptions — all have recurring programs that reward patient, high-quality content.
The compounding effect is real. I have affiliate links in posts I wrote in 2023 that still produce $30-80/month between them. My sponsored revenue from the same period is exactly $0, because those deals were one-time placements in videos I made that quarter.
My Recommendation for Anyone Reading This
I do not write these posts as advertisements. I do not get paid to recommend anything I do not use. But if you are a tech creator, especially one whose audience overlaps with developers, builders, or AI-curious engineers, the Global API affiliate program is worth your serious attention.
Three reasons I recommend it specifically:
- The 15% first-order + 8% recurring + 10% premium stack is one of the better AI API commission structures I have seen. Most affiliate programs in this space offer flat 10-20% one-time, which means they expire the moment your reader subscribes.
- 150+ models through one platform makes it an easy recommendation. You are not shilling a single vendor's LLM, you are pointing people
