How to Launch an Affiliate Program: A Brand-Side Playbook.

To launch an affiliate program, a brand sets an allowable cost per acquisition from its margins, picks a tracking platform or network, writes commission tiers and program terms, tests tracking end to end, then recruits and activates partners by hand for the first 90 days. The work that decides whether it makes money happens before the first partner joins.

This guide is for in-house marketing leads and owners at brands doing roughly $5M to $500M in revenue who are starting a program or restarting one that stalled. We run programs for brands and we also publish on these networks, so we see both sides: what brands write in their terms, and what partners actually read before they decide to promote. For how we run this work, see our affiliate and partnerships service.

How an affiliate program works.

A partner (a publisher, creator, coupon site, loyalty app or another brand) sends a shopper to your site with a tracked link. The tracking platform records the click, your site reports the order back, and the platform credits the partner with a commission after a locking period in which you can reverse returns and fraud. You pay the commission plus the platform or network fee.

Three decisions shape everything else: what you can afford to pay per customer, who sits between you and the partners, and which partner behavior you will and will not pay for. Get those in writing first.

Goals and economics: your allowable CPA.

Start with what one new customer is worth, not with what competitors pay. Allowable CPA is the most you can pay, in commission plus fees, for one order and still hit your profit target. A simple version:

• First-order contribution. Average order value, minus cost of goods, shipping, payment fees and expected returns.
• Repeat value. Contribution from repeat orders inside the payback window you accept, such as 6 or 12 months, using your own cohort data.
• Target profit. What you need left over per customer after acquisition cost.
• Allowable CPA = first-order contribution + repeat value in the window, minus target profit.

An illustration: an $80 average order with $36 of contribution after product, shipping and returns, plus $20 of expected repeat contribution in 12 months, gives $56 per customer. If you want $26 of that left as profit, your allowable CPA is $30. Divide by order value and you get the maximum all-in rate: $30 on $80 is 37.5% for a new customer. Network fees come out of that number too, so the partner commission ends up lower.

Run the same math for returning customers. Their first-order contribution has no acquisition value attached, so the allowable cost is far lower. That gap is why tiered commissions by customer type matter more than any other rate decision.

Picking a platform or a network.

A platform (often called SaaS tracking) gives you the software and you recruit partners yourself. A network gives you tracking plus a marketplace of publishers who already have accounts, payment details and tax forms on file. Costs below are list prices as of November 2026; check the vendor page before you sign.

Two checks matter more than the headline fee. First, ask the top 20 publishers you want which networks they work on; some large publishers only join through one or two. Second, read the setup and onboarding terms: impact.com, for example, lists setup and onboarding services at $250 an hour on its paid tiers. If you sell mostly on Amazon, the decision is different; see Levanta vs Amazon Creator Connections.

Commission structure and tiers.

Pick a base rate a partner can plan around, then use tiers and bonuses to pay for what you actually want more of. Common structures:

• New vs returning customer. A higher rate for new customers and a lower one, or none, for existing customers. Needs a customer flag passed in the conversion.
• Partner type. Content and review sites at the base or higher rate; coupon, cashback and loyalty partners at a lower rate, since they often touch shoppers already at checkout.
• Performance tiers. A step up after a partner passes a monthly sales threshold. Keep the steps few and the thresholds reachable.
• Category or margin rates. Lower rates on low-margin products, bundles or clearance.
• Flat fees and placement fees. Some publishers sell guaranteed placements in newsletters or roundups. Treat these as media buys with their own return target.
• Launch bonuses. A time-boxed bonus for a first sale or for content published in the first 60 days.

Set the cookie or referral window and the locking period at the same time. Partners compare these across brands, and a 7-day window in a category where peers offer 30 days reads as a lower rate.

Program terms: coupons, brand bidding, trademark and disclosure.

Terms are where most of the money is won or lost. Partners read them; the ones who intend to break them read them closest.

• Coupons. Say which codes partners may publish. Unauthorized or leaked codes on coupon sites are the most common source of commission paid on sales that would have happened anyway. Assign unique codes per partner where possible.
• Brand bidding. Google's trademark policy lists using trademarks as keywords among uses it does not restrict, so your terms are what stop affiliates bidding on your brand name. Most brands ban bidding on brand terms, misspellings and brand plus coupon terms, and ban direct linking from paid search.
• Trademark use. Say whether partners may use your name in domains, social handles and ad text, and how they may use your logo and product images.
• Disclosure. Require a clear disclosure of the affiliate relationship near every link and in every video or post, following the FTC Endorsement Guides.
• Claims. List claims partners may not make, such as health, earnings or comparative claims you cannot substantiate.
• Reversals. Define what gets reversed: returns, cancellations, fraud, orders that break terms, and duplicates.

On disclosure, the FTC's business guidance on the Endorsement Guides tells affiliates to disclose their relationship clearly and conspicuously, and notes that a single disclosure on a home page is not enough. It also puts responsibility on the brand:

Tracking and postbacks.

Tracking breaks quietly. A partner sees clicks but no sales, assumes your program does not convert, and moves on. Before launch:

Recruiting the first 50 partners.

Opening the program on a network marketplace and waiting brings mostly coupon and cashback sites. The partners who create demand have to be asked. A workable list for the first 50:

• Search results. The sites ranking for "best [your category]", "[competitor] review" and "[competitor] alternatives". These are the pages shoppers read before buying.
• Competitor programs. Publishers already promoting competitors know the category and have the audience.
• Existing fans. Customers, creators and reviewers who already mention you without being paid.
• Newsletters and communities. Category newsletters and niche creators with smaller but engaged audiences.
• Complementary brands. Brands that sell to the same customer and can promote you to their list.
• A small number of coupon and loyalty partners, on the lower rate, so checkout searches for your codes land on partners you control.

Personal outreach works better than templates. Tell each partner what your rate is, why your product converts, what you will send them (samples, images, early access), and who to contact. From the publisher side, a brand that answers within a day and sends product is the one we write about first.

Activation: from joined to posting.

Most approved partners never send a sale. Activation is the part brands skip. Send samples to content partners, share a short brief with your product facts and claims you can support, offer a launch bonus for content published within a set window, and follow up on partners who joined but have not posted. Keep a simple list of every partner with status: invited, joined, content live, first sale.

Fraud and reversals.

Review new partners before approval: real site or channel, real audience, traffic sources that match their claims. After launch, watch for patterns:

• Very high conversion rates with very short time from click to order, which can point to cookie stuffing or partners intercepting checkout traffic.
• Sales from a partner rising when your own brand search or email campaigns run.
• Coupon codes you never gave out showing up on coupon sites.
• Clusters of orders with the same address, device or payment details, and high return rates from one partner.
• Partner ads appearing on your brand terms in search.

Reverse orders that break the terms before the lock date, tell the partner why in writing, and remove repeat offenders. Fair, documented reversals keep good partners; arbitrary ones drive them away.

Reporting incrementality.

Attributed revenue in the platform tells you who got credit, not who caused the sale. To see what the program adds:

• New customer share by partner. The single most useful number. Content partners should skew to new customers; if a coupon partner's orders are mostly returning customers, its rate is too high.
• Click-to-order time and path. Partners that touch shoppers only in the last minutes before checkout deserve scrutiny.
• Holdout or geo tests. Pause a partner type in a region or for a period and compare total sales, not affiliate sales.
• Margin after commissions and fees. Compare all-in cost per new customer against your allowable CPA from the first step.

The first 90 days plan.

Mistakes agencies see brands make.

• Copying a competitor's commission rate without checking their margins against yours.
• Paying the same rate on returning customers as new ones.
• Opening the program with no brand bidding or coupon rules, then trying to add them after partners have built around the gaps.
• Launching with browser-only tracking and never running a test order on mobile.
• Reading platform revenue as the result and never checking new customer share or margin.
• Letting the program run unattended.

What to measure.

If you are a smaller brand.

Below a few million in revenue, keep fixed costs low: a lower-tier platform plan or a network plan with a small monthly fee, and a short list of 10 to 20 hand-picked partners rather than 50. Lean on creators and customers who already like the product. Above all, still write the brand bidding and coupon terms; small programs get hurt by them just as much.

When to bring in help.

Bring in help when nobody in-house can own recruiting and activation each week, or when the program has grown but nobody knows which partners are incremental. An outsourced program manager handles recruiting, terms enforcement and reporting; our guide to affiliate program management and OPMs explains the models, and how to hire an affiliate marketing agency covers what to ask.
