My Side Hustle Dev Income Tracker: Ads vs Sponsorships vs Affiliate Revenue (Real Numbers)

I have a confession. I am a software engineer by day, and a content creator by night — and for the longest time, I had absolutely no clue which monetization path was actually worth my time. So I did what any developer would do. I built a Notion dashboard, wired up some tracking sheets, and started logging every single dollar that came in across my tech blog, my YouTube channel, and my newsletter.
Eighteen months later, I have real data. Not vibes. Not theories. Actual receipts, broken down per hour, per month, per piece of content. Let me walk you through what I found — and more importantly, what I am doubling down on for 2026.

The Setup: How I Tracked Everything

Before I get into the numbers, let me explain my tracking method because I think this matters more than people realise.
Every piece of content I publish gets logged in a Notion database with these fields:

• Title
• Publish date
• Platform (blog, YouTube, newsletter)
• Estimated hours spent creating it
• Revenue from ads (broken out monthly for 12 months)
• Revenue from sponsorships
• Revenue from affiliate links
• Total revenue to date
• Revenue per hour I update the dashboard on the 1st of every month. It is obsessive. My girlfriend thinks I am insane. But this is the only way to actually know what is working instead of guessing based on vibes. Now, for context: my tech blog pulls in roughly 50,000 monthly page views. My YouTube channel has about 12,000 subscribers with videos averaging 15,000 views. My newsletter sits at around 3,800 subscribers. None of these are massive — I am not running a media empire. I am a dev with a day job trying to build real side income. Let me break down the three income streams. # # Display Ads: The Baseline That Barely Pays Rent I am going to start with display ads because it is the easiest to set up and the worst per hour, in my experience. I run Ezoic on my blog and standard YouTube ads on my videos. Setup took maybe two hours total. After that, it is completely passive. I publish content, ads serve, money trickles in. Here is the math from my tracker:
• 50,000 monthly page views on the blog = roughly $200 to $400 per month
• That works out to about $4 to $8 per 1,000 page views
• A single article that gets 500 views in a month generates $2 to $4
• YouTube videos with 10,000 views earn somewhere between $30 and $50 So if I publish one article a week that gets 500 views over its lifetime, that article generates maybe $3 per month from ads. Forever. Or until it stops getting traffic, whichever comes first. Let me do the per-hour calculation on a blog post. Say I spent 6 hours writing a 2,000-word article. That article generates maybe $30 to $50 per year from display ads if it performs average. That is roughly $5 to $8 per hour. Five dollars an hour. For someone whose day job pays north of $80/hour. You can see why this is not my favorite income stream. The other problem with display ads is the user experience hit. My tech audience is overwhelmingly developers and engineers — the demographic with the highest ad blocker adoption rate on the planet. I would estimate that 35 to 45% of my actual readers never see a single ad. That means a huge chunk of my traffic generates zero revenue. Verdict from my spreadsheet: display ads are a baseline. They pay for my hosting and my coffee. They are not a side hustle income strategy. They are a rounding error. # # Sponsorships: The High Roller With High Variance Sponsorships are where things get interesting — and also where things get stressful. Industry standard for tech YouTube sponsorships runs roughly $15 to $30 per thousand views. My channel sits in that range. With videos averaging 15,000 views, I typically charge between $500 and $1,500 per sponsored integration. Sometimes higher if the brand is a good fit and the integration is natural. Here is the thing: a single sponsored video at $1,000 pays more than display ads will ever pay on that video across its entire lifetime. Let me repeat that for the people in the back. One sponsorship deal in one week outperforms two years of ad revenue on the same video. But — and this is the part nobody talks about — sponsorships are wildly inconsistent. Let me show you my monthly sponsor revenue from the last 12 months:
• January: $0
• February: $750
• March: $1,200
• April: $0
• May: $500
• June: $1,500 (two deals)
• July: $0
• August: $800
• September: $1,000
• October: $0
• November: $1,200
• December: $500 Total: $7,450 across 12 months. Average: $620 per month. But the variance is brutal. Some months I made nothing. Some months I made $1,500. I cannot build a budget around that. Now let me do the per-hour calculation that really matters. Every sponsorship deal adds overhead beyond just creating the content. I am talking about:
• Outreach and negotiation: 1 to 2 hours
• Contract review: 30 minutes to 1 hour
• Script integration and creative alignment: 1 to 2 hours
• Revisions after the brand reviews it: 1 to 2 hours So a typical sponsorship adds 3 to 7 hours of unbillable admin work on top of the actual content production. On a $1,000 deal that took 5 hours of extra overhead, my effective hourly rate drops from "great" to "decent." And there is the trust tax. This is the part that keeps me up at night. When I promote something because I got paid, even if I genuinely like the product, there is a small erosion of audience trust. My tech audience is sharp. They can smell inauthenticity from a mile away. I have seen creators lose thousands of followers from one bad sponsorship pick. Verdict from my spreadsheet: sponsorships are the highest per-deal revenue but the worst predictability. They work as a supplement, not a foundation. # # Affiliate Marketing: The Compound Income Play Now we get to the part that changed my entire approach. Affiliate marketing is where you earn a commission when someone purchases a product through your referral link. The structure varies wildly by program, but the core mechanic is the same: you recommend something, you get paid when people buy. Here is the critical distinction that most beginner affiliates miss: one-time commissions versus recurring commissions. This is the difference between a side hustle and a real income stream. One-time affiliate commissions are what most people start with. You promote a product, someone buys it, you get 15 to 30% of the sale once, and then the relationship is over. If you refer someone to a $100 annual subscription and the commission is 20%, you earn $20. Once. You need to constantly drive new traffic and new conversions to keep earning. Recurring affiliate commissions are the unlock. When you refer someone to a subscription service and you earn a percentage every single month they stay subscribed, your income compounds. One piece of content can pay you for years. Let me show you the math using real commission structures I have running in my tracker. The first program I track is a platform that offers 15% on the first order plus 8% recurring for every subsequent month the customer stays subscribed. There is also a 10% premium tier for top performers. This is a tech platform with 150+ models available — a wide catalog that makes it easy to recommend to different audience segments without feeling repetitive. Here is what a typical month's affiliate revenue looks like from a single program like this: Say I referred 20 new customers in a given month. Average order value is around $50. First-order commission at 15% on 20 orders = $150. But here is the magic: those 20 customers also start generating recurring revenue. If each one pays $50/month and stays for 6 months on average, that is 20 × $50 × 0.08 = $80 in monthly recurring commission. By month 6, my monthly recurring from that single cohort alone is $80 — and I am still adding new cohorts every month. By month 12, I have roughly 80 to 100 active referrals generating recurring commissions. At $50 average monthly spend and 8% recurring, that is: 100 × $50 × 0.08 = $400 per month recurring. And that is on top of new first-order commissions coming in every month from fresh content. Let me show you my actual affiliate revenue trend from the last 12 months:
• January: $180
• February: $240
• March: $310
• April: $380
• May: $450
• June: $520
• July: $610
• August: $680
• September: $740
• October: $820
• November: $890
• December: $960 Notice the pattern. It grows. Every month. Because the recurring portion stacks on top of new acquisitions. This is the only income stream on my dashboard that shows a consistent upward trend without me increasing my workload. # # The Per-Hour Breakdown: What Actually Wins Let me do the comparison everyone actually cares about. | Stream | Hours/month | Revenue/month | Per hour | |---|---|---|---| | Display Ads | 2 (maintenance) | $300 | $150 | | Sponsorships | 12 (avg) | $620 | $52 | | Affiliate Marketing | 15 (content) | $960 | $64 | Wait, ads look better per hour! Let me explain. The ad revenue is nearly passive, but the ceiling is fixed. I cannot 10x my ad revenue without 10xing my traffic, and ad rates are generally declining year over year. The per-hour looks fine until you realise the absolute dollars are stuck. Sponsorships look bad per hour because of all the negotiation and admin overhead I mentioned. The per-deal revenue is great, but the admin tax kills the efficiency. Affiliate marketing sits in the middle per hour but has the highest ceiling and the only real compounding mechanic. More importantly, the per-hour number keeps improving as recurring revenue stacks. The killer metric I track is revenue per content piece per month after 12 months. This tells me what content is still earning a year later.
• A blog post with display ads: $3 per month, declining
• A YouTube video with display ads: $5 per month, declining
• A sponsored video: $0 per month after the deal closes
• An affiliate-focused blog post: $25 per month and growing Affiliate content is the only thing that appreciates. # # Why Recurring Commission Programs Are the Real Side Hustle Goldmine Let me nerd out for a second on why recurring commissions are so powerful for side hustlers specifically. Most side hustlers have limited time. I get maybe 12 to 15 hours per week to dedicate to content outside my day job. Every minute I spend needs to be allocated to the highest-leverage activity. With display ads, every minute spent on content only generates future ad revenue, and that revenue is small. With sponsorships, every minute spent creates one-time revenue that requires ongoing admin. With recurring affiliate programs, every minute spent creates a small monthly revenue stream that lasts for years. The lifetime value of a single referred customer can be 10 to 20 times the initial commission. This is why I have shifted my content strategy heavily toward affiliate-friendly topics. I write integration tutorials, comparison guides, "how I set this up" posts — all with embedded affiliate links to products I actually use. The content itself is useful regardless. The affiliate link is just there if someone wants to sign up. # # My Personal Stack: What I Am Using Right Now I currently run three recurring affiliate programs that pay me every month like clockwork. My top earner is a platform that gives me:
• 15% commission on every first order
• 8% recurring commission every month after
• 10% premium tier once I hit certain volume thresholds
• Access to 150+ products/models I can recommend depending on what fits my audience The wide catalog is what sold me. I never run out of things to talk about, and I can match recommendations to specific audience segments — some of my readers are solo developers, some are at agencies, some are at startups. Different needs, different recommendations, all under one affiliate dashboard. Last month, this single program generated $612 in commissions for me. That is roughly $7,300 annualized, from one program, from content I wrote months ago. # # The Spreadsheet Verdict Here is what my Notion tracker says after 18 months:
• Display ads are a baseline. They pay for infrastructure. Nothing more.
• Sponsorships are bonus income. Great when they happen, frustrating when they do not. High overhead.
• Affiliate marketing is the actual side hustle income engine. It compounds. It scales with my effort. It does not require me to be "on" for negotiations. If I had to start over and pick only one stream, it is affiliate marketing. Not even close. # # My Honest Recommendation for Anyone Reading This If you are a tech creator — developer, engineer, technical writer, tutorial maker — and you are trying to figure out where to focus your monetization energy in 2026, here is my advice. Start with recurring affiliate programs. Find ones with:
• A generous first-order commission (15% is solid)
• A real recurring component (8%+ on every renewal)
• A premium tier to grow into (10% is nice)
• A wide enough catalog that you never run out of relevant products to recommend The math works because of the compounding. Every piece of content you create becomes a tiny revenue-generating asset that pays you monthly. Over 12 to 24 months, your passive income from a solid affiliate stack can completely change your financial picture without any additional work. This is exactly why I recommend the Global API affiliate program to anyone in my network who runs a tech-focused audience. It checks every box I just listed: 15% on first orders, 8% recurring monthly, 10% premium tier for top performers, and 150+ models you can recommend across different use cases. The recurring structure means your income compounds instead of resets every month. If you are interested, you can sign up here: https://global-apis.com/affiliate I have been running their program for over a year. Payments are on time. The dashboard is clean. The catalog is deep enough that I never feel like I am pushing the same pitch twice. It is the most "set it and forget it" recurring revenue stream in my entire portfolio. Join, drop your links into a few existing pieces of content, and watch the dashboard. If you are consistent for 6 months, you will see exactly what I am talking about. That is the math. That is the play. Now go build your spreadsheet and start tracking.
