No. You can earn from affiliate links with no website at all, and plenty of people do.
But the answer changes depending on who is asking — the merchant, the network, or you — and the reasons a website helps are not the ones usually given.
What the networks actually require
Most require a promotional space, not specifically a website. A YouTube channel, a substantial social account, a newsletter or an app all qualify. The application asks where you will promote and expects something real and verifiable.
What gets applications declined is not the absence of a website. It is the absence of anything at all — an application listing no channels, or listing accounts with almost no content.
Individual merchants are stricter than networks. Some do require a website, and some decline social-only applicants as a matter of policy. So without one your options narrow, but they do not close.
| Promoting through | Works? | The catch |
|---|---|---|
| YouTube | Yes, well | Descriptions are indexed and links persist |
| Newsletter | Yes, very well | You own the list; no algorithm in between |
| Instagram / TikTok | Yes, with friction | One bio link; captions are not clickable |
| Yes | Some programmes prohibit it — check first | |
| Reddit / forums | Rarely | Most communities ban affiliate links outright |
| Paid ads direct to links | Usually prohibited | Breaches most programme terms |
Why a site earns differently
A social post reaches its audience over a few days and then stops. An article that ranks keeps being found, and someone searching a specific question is closer to buying than someone scrolling a feed.
You also control the context. Links can sit inside a comparison at the moment the reader is deciding, rather than in a bio three taps away. And nobody can change the rules on you — a platform can restrict outbound links overnight and has, repeatedly.
What to do without one
Start with a newsletter. It is the closest thing to owning a website without building one — you keep the list, delivery does not depend on an algorithm, and links are clickable in the body rather than confined to a bio.
If you are applying to networks with social channels only, make the application concrete: name the channels, state the audience size and locations, and describe how you promote. “Instagram” is not an answer; a handle with 8,000 followers and a stated niche is.
And put the disclosure somewhere permanent — how to write a disclosure covers the wording. Without a site there is no obvious place for it, which is exactly why social-only applicants get declined more often than they should.
The honest recommendation
Start without one. Prove your audience buys something before spending months building a site nobody visits.
Then build one, because the income behaves differently. Social affiliate income is earned again every week; site affiliate income accumulates. The second is the one that is still paying in three years.
