Income reports are marketing. The people publishing them are, almost without exception, selling a course on how to do what they did — which makes the reports promotional material, not data.
Here's a more sober framing.
The distribution is extremely skewed
Affiliate earnings follow a power law. A small number of sites earn most of the money; the large majority earn very little.
Industry surveys consistently show something like this shape:
| Segment | Rough share | Monthly earnings | |---|---|---| | Never earn meaningfully | Majority | $0–$100 | | Modest side income | Large minority | $100–$1,000 | | Meaningful income | Small minority | $1,000–$10,000 | | Full-time businesses | Few percent | $10,000+ |
The exact numbers vary by survey and none are rigorous, but every source agrees on the shape: most participants earn close to nothing, and the successful minority earn a lot.
That's not discouraging so much as clarifying. The question isn't "what's the average" — averages are meaningless in a power law. It's "what puts you in the upper group".
Why so many earn nothing
Most affiliate sites are abandoned. Someone reads a guide, buys a domain, publishes six posts over two months, sees $0, and stops. That site is in the "earn nothing" bucket forever, and there are a great many of them.
Among sites that keep publishing for a year or more, the picture improves dramatically. Survivorship works both ways.
What determines the outcome
Time. Almost nothing earns in months one to six. Search rankings take time to establish regardless of content quality. Sites that persist to month twelve are in an entirely different position from those that stop at month four.
Niche economics. A referral in B2B software or finance can be worth 50–100× one in general consumer goods. Same traffic, wildly different revenue. This is the single biggest lever and it's chosen on day one.
Recurring vs one-off. Recurring commissions compound: every month's referrals stack on the last. A year of steady referrals produces a base income arriving whether or not you publish again.
Traffic quality. Ten thousand visitors reading "what is affiliate marketing" are worth less than five hundred reading "X vs Y pricing". Buyer intent matters more than volume.
Genuine expertise. The sites that win now are written by people who actually know the subject. That's harder to fake than it was and getting harder still.
A rough model
If you want an estimate rather than a fantasy:
Monthly income ≈ visitors × click rate × conversion rate × commission
For a content site with reasonable buyer intent, plausible figures are a 5–15% click rate on affiliate links and a 1–5% conversion on those clicks. So per 1,000 visitors, expect roughly 50–150 clicks and one to seven conversions.
At a $50 commission, 1,000 monthly visitors is something like $50–$350 a month. At a $300 commission — realistic in B2B software or finance — the same traffic is $300–$2,100.
That arithmetic is the entire argument for choosing a high-value niche. Traffic is the hard part; commission size is chosen for free at the start.
What a realistic first two years looks like
Months 1–3: Publishing, no traffic, no income. Nothing is wrong; this is the shape of it.
Months 4–6: First rankings appear on long-tail terms. Traffic in the hundreds. First commissions — often literally a few dollars, which is nonetheless a real signal.
Months 7–12: Compounding begins. Traffic in the low thousands. Income becomes noticeable rather than symbolic.
Year 2: If you kept publishing and some articles ranked, this is where it becomes meaningful. If nothing ranked by month eighteen, something structural is wrong — usually niche choice or content quality — and more of the same won't fix it.
The honest summary
Affiliate marketing is a real way to earn money and a poor way to earn money quickly. It rewards subject knowledge, patience, and picking a niche where each referral is worth something.
Anyone showing you a screenshot of month-three earnings is selling something. Anyone telling you it takes a year of work before it's meaningful is telling you the truth.
