Digital income
Affiliate Websites
Content built around purchase decisions, paid a commission when a reader goes on to buy.
How the money actually reaches you
A merchant runs an affiliate programme, either in-house or through an affiliate network that handles tracking and payment for many merchants at once. You place a tagged link; a reader clicks it; the network records the click and, if that reader buys within the cookie window, attributes the sale to you. The commission is held until the merchant's return and chargeback window closes, then approved, then paid on the network's cycle — so the money arrives well after the sale and part of it gets reversed when goods come back. The merchant sets the rate, the window, the excluded categories and the terms, and can change any of them at any time.
A merchant, an advertiser or a lead buyer pays, usually through an affiliate network or tracking platform that both sides trust to count the events. You are paid per sale, per qualified lead, or occasionally per action, on terms the merchant writes and can rewrite.
After a lock period. The sale has to clear the merchant's return, cancellation or chargeback window before the commission is approved, and the network then pays on its own cycle. Reversals are normal and land after the fact.
Read the payer, the intermediary and the schedule before anything else. Who pays, who sits in the middle taking a share, and how long after the work the money arrives explain most of the difference between these fourteen businesses.
The structural facts
Six lines, in two halves. The first three are what the model takes — money up front, waiting time, and the rhythm of work it never stops needing. The last three are what happens once it earns: how the income fades if nothing new is added, what stops it growing past a point, and what, if anything, stops the next person copying it. A model with no answer to the last two can still pay; it just does not compound.
- Capital to start
- Low in cash. The spend is on content and, for anyone buying reviewed products rather than borrowing them, on the products themselves.
- Time to first dollar
- Months. The first commission usually arrives long before the traffic is worth anything, because a single well-timed page can convert.
- Ongoing effort
- High and unglamorous: prices move, products are discontinued, links rot, programmes close, and every stale recommendation is a page that now converts at zero.
- How it decays
- Fast and specific. Affiliate content decays twice — once when rankings shift and again when the products themselves change. A page about last year's model is worth less than nothing if it misleads a reader.
- What caps it
- The number of genuine buying decisions in your niche and the commission the merchants in it will pay. Both are finite and neither is yours to set.
- What stops a copycat
- Real testing nobody else has done, a reputation readers return for by name, and direct relationships with merchants that get you better terms than the public programme. Rewritten spec sheets have no moat at all and are the first thing search engines demote.
What it costs to run
- Hosting, domain and content production
- Products purchased for genuine testing
- Link management, rank tracking and analytics tools
- Legal review of disclosure language
- Bookkeeping
How it typically fails
- The merchant cuts the commission rate or shuts the programme, and revenue halves in a night with the content unchanged.
- Attribution quietly fails — blocked cookies, stripped parameters, a coupon site taking last click.
- The content is a rewrite of the manufacturer's page, so it never ranks and never converts.
- Reviews stop being honest to chase the higher-paying programme, and the audience notices before the regulator does.
- Required advertising disclosures are missing or buried, which is both a legal problem and a network-termination problem.
Does it sell?
Whether a business can be sold is the plainest test of whether it is an asset or a job. A buyer pays for income that continues without the person who built it, which means verifiable revenue, a customer relationship that transfers, and a distribution channel that does not walk out of the door with the founder. This section describes whether that market exists for this model — not what anything is worth, which no honest public source can give.
Affiliate sites trade in the same broker and marketplace category as other content sites, and buyers scrutinise the same things plus one more: how much of the revenue depends on a single merchant programme. Concentration in one programme is the discount a buyer will name out loud.
