Affiliate marketing

What is affiliate marketing?

In affiliate marketing, other people promote your product using a unique tracking link, and you pay them only when that promotion produces a result you care about, usually a sale or a paid signup. The affiliate might be a blogger, a YouTuber, a newsletter writer, a comparison site, or another company whose audience overlaps with yours. Tracking software attributes each conversion to the right link, calculates the commission, and handles payouts.

The model is older than the internet (referral fees have existed forever), but online tracking made it scalable and precise. Instead of guessing which partner sent you a customer, a cookie or a coupon code tells you exactly, down to the click.

Running a program day to day means setting commission terms, recruiting partners, giving them honest product knowledge and assets, watching for fraud, and paying out on schedule. It is closer to managing a small sales channel than to running an ad campaign.

Why affiliate marketing matters for startups

For a small team, the appeal is simple: you pay for outcomes, not exposure. Ads charge you whether or not anyone buys. Affiliates only cost money when revenue arrives, which turns part of your customer acquisition cost from a risky fixed bet into a predictable variable expense. That makes it one of the few channels a team with almost no budget can run seriously, a theme the zero-budget marketing guide covers in more depth.

The catch: you give up margin and some control over how your product is described, and good affiliates only promote products that already convert. Affiliate marketing amplifies a working funnel; it cannot fix a broken one.

Affiliate marketing in practice

Imagine you sell a $29 per month screenshot tool and launch a program paying 25 percent recurring commission. A productivity newsletter writer reviews it, sends about 900 clicks, and 45 readers start trials, of which 20 convert to paid. You now pay the writer roughly $145 per month for as long as those customers stay, while collecting about $580 per month from them. No upfront spend, no wasted budget, and the writer is motivated to mention you again.

Benchmarks and rules of thumb

• Many SaaS affiliate programs pay between 20 and 30 percent recurring commission, or a one-time bounty roughly equal to the first month or two of revenue.
• Physical product commissions are usually far lower, often in the 5 to 15 percent range, because margins are thinner.
• Results tend to be concentrated: a small handful of partners typically drives most affiliate revenue. Invest in relationships with your best few, not in raw signup counts.

Common mistakes

• Launching a program before the product converts. Affiliates test your funnel with their first sends. If nothing converts, they leave and rarely come back. Fix conversion first.
• Treating recruitment as passive. Posting a "Partners" page and waiting produces almost nothing. The programs that work recruit specific creators and publishers one by one.
• Paying commissions your margins cannot support. A generous rate that breaks your unit economics just scales a loss. Model the math before setting terms.
• Ignoring coupon and brand-bidding abuse. Some "affiliates" simply intercept buyers who were already converting, via coupon sites or ads on your brand name. Write rules against it and enforce them.
• Measuring clicks instead of revenue. Traffic from affiliates is worthless if it never pays. Judge partners on customers delivered and their return on investment, not on visits.

Affiliate marketing sits next to influencer marketing, which pays for reach and association rather than tracked results, and it often rides on partners' content marketing, since reviews and comparison posts are where most affiliate links live. Before leaning on the channel, know your numbers: commission structure only works when acquisition cost, margin, and retention line up.
