Digital-asset & online-business income
Affiliate Websites
A content site paid a commission by merchants when a reader clicks a tracked link and then buys, with the merchant — not the reader — writing the cheque.
An affiliate website earns commissions by referring buyers to merchants through tracked links. The publisher joins an affiliate network or a merchant's direct program, receives a unique tracking link, and is credited a percentage of the sale (or a flat bounty) when a referred visitor purchases within the cookie window. Income is uncontracted, attributable only if tracking survives, and subject to clawback when the buyer returns the product.
Business profits Semi-passive
The labels above place this income type before you read a word. The first is the mechanism — how the money actually reaches you, whether by lending it out, owning a slice of something, renting an asset, licensing a right, selling an option or owning a business somebody else runs. The second says whether the income keeps arriving on its own once it is running, or whether it needs work from you to keep coming. Both are descriptions of how the thing is built, not verdicts on it.
How it works
A publisher applies to a merchant's affiliate program, either directly or through a network such as CJ, Impact, Awin/ShareASale, or Rakuten, and receives tracked links carrying a unique publisher ID. When a reader clicks, the network drops a cookie or records a click ID; if that visitor buys inside the cookie window, the sale is attributed to the publisher and a commission is recorded. The window is set by the merchant, not the publisher, and can run from a single day at a large marketplace to a month or more for a considered purchase — and it can be shortened unilaterally with no negotiation.
Attribution is normally last-click: if the same reader later clicks a coupon site or a competing publisher's link before buying, that other publisher takes the commission instead, regardless of who did the work of persuading the buyer. The commission itself sits in a pending state through the merchant's return period before it is approved; returns, cancellations, chargebacks and duplicate orders are reversed out of the publisher's balance during that window.
Networks pay on a threshold-plus-net-30-to-net-60 schedule, so an approved commission can land sixty to ninety days after the click that generated it. The content that converts is narrow — comparison pages, buying guides, hands-on reviews, alternatives-to pages and tool round-ups — because it meets a reader who has already decided to buy and is choosing where. US law requires clear, conspicuous disclosure of the affiliate relationship under the FTC's endorsement guides, placed above the first affiliate link rather than in a footer.
What it pays
Publishers track earnings per hundred clicks (EPC) because it collapses the two variables that matter — how often referred visitors buy, and how much the merchant pays per sale — into one comparable figure across offers. Commission structure varies sharply by category: physical retail typically pays a small percentage of a modest basket, while software, hosting, insurance and financial products often pay a flat bounty or a share of first-year revenue instead.
Recurring-commission programs, common in SaaS, hosting and membership products, pay for as long as the referred customer keeps paying, which behaves more like an annuity than a one-time bounty. Average order value multiplies everything underneath it: the same conversion rate applied to a high-ticket category produces a materially different outcome than it does applied to a low-ticket one.
Merchants also run tiered rates, lifting the commission for the following month if a publisher clears a volume threshold or performs well during a promotional period. None of this is guaranteed income against a reversal rate, which is a real deduction rather than an edge case — apparel and consumer electronics in particular carry high return rates that permanently reduce net commissions after the fact.
Costs and taxes
The cost structure matches any content site: hosting, a domain, content production, an email tool, and link-management or cloaking software. Some publishers additionally buy traffic — search or social ads pointed at affiliate offers — which converts the model from a content asset into a media-buying business with a much shorter payback period and much higher risk of loss. There is no cost of goods, no inventory and no customer service to fund, because the merchant owns fulfilment, returns and support end to end.
In the US, commissions are ordinary business income reported on Schedule C or through an LLC or S-corporation return, with self-employment tax due on net profit for a sole proprietor. Networks and merchants issue Form 1099-NEC to US publishers above the reporting threshold; non-US publishers file a W-8BEN instead. The publisher is never the seller of record, so it collects no sales tax on any transaction — that liability sits with the merchant.
Historic state affiliate-nexus laws once caused large retailers to terminate publishers located in particular states rather than register to collect tax there. The post-Wayfair marketplace-facilitator regime has largely displaced that specific issue, but merchant program terms still vary by jurisdiction and can change without much notice.
Liquidity and time commitment
An affiliate site is illiquid in the same way any ad-supported site is: sale runs through a broker at a multiple of trailing profit, with buyers doing diligence on network statements and traffic sources over weeks to months. Buyers discount sites with a single dominant merchant heavily, because the entire cash flow can be cancelled by one program manager's decision.
Ongoing work concentrates in a small number of recurring tasks — keeping prices and product recommendations current, replacing dead links and discontinued products, refreshing rankings, and monitoring the reversal rate. A merchant rate cut forces re-work on short notice: halving the commission on a page can turn the site's best earner into its worst overnight.
Cash flow lags activity by two to three months because of the pending-and-approval cycle, so a working-capital buffer is normal even in a business that carries no inventory. The work is delegable to writers operating from a maintenance checklist, which is what makes an established affiliate site semi-passive rather than an ongoing job.
How it goes wrong
Merchants close affiliate programs, cut rates, or remove publishers from a program with no notice and no compensation for content already written and ranked. Attribution failure compounds this quietly: browser tracking restrictions, ad blockers, app deep-links that bypass the browser, and coupon-extension overwrites of the last click all erode credited sales even while raw traffic stays flat.
Search algorithm updates aimed at thin review content have repeatedly wiped out affiliate sites that reviewed products without ever handling them. Reversal shock is a separate hazard — a merchant re-auditing a prior period can claw back commissions that were already reported as income months earlier.
Regulatory exposure follows undisclosed endorsements or unsubstantiated claims, particularly in health, supplements and financial products, where the FTC has been most active in enforcement. Concentration on one merchant, one network, or one traffic source is the standard failure mode and the risk factor buyers price hardest during acquisition. A newer threat is structural: merchants building their own comparison and buying-guide content and outranking the affiliates who once sent them traffic, removing the intermediary the whole model depends on.
What to remember
- The merchant, not the reader, pays the commission, and only if the network's tracking successfully attributes the sale to the publisher's link inside the cookie window.
- Last-click attribution means a coupon site or a rival publisher can take the commission even after another site did the work of persuading the buyer.
- Approved income lags the original click by two to three months due to return periods and net-30/60 payment schedules, and can still be clawed back later.
- Recurring-commission programs behave like an annuity for as long as the referred customer keeps paying; one-time bounty programs do not.
- Concentration in a single merchant or traffic source is the main structural risk, since a program can be cut or terminated with no notice and no recourse.
- US commissions are ordinary self-employment business income on Schedule C or an entity return; the publisher never collects sales tax because it is never the seller of record.
This page explains how the income type works, which does not change from week to week, so it deliberately carries no rate and no price.

Read the mechanism here first: the numbers there are far easier to judge once you know what they are measuring.
