Affiliate marketing for ecommerce lets other people promote your products and you only pay them when a sale actually happens. It’s one of several channels ecommerce brands lean on alongside other proven ways to grow sales, and this guide covers how it works, what it costs, and how to set up a program that actually attracts partners.
- Affiliate marketing means paying independent partners (bloggers, influencers, review sites, coupon sites) a commission for sales they refer to your store, usually tracked with a unique link or code.
- Most physical product brands pay commissions in the 5 to 15 percent range per sale, with higher margin categories sometimes going up to 20 to 30 percent.
- You can run a program through a network (ShareASale, Awin, Impact, CJ Affiliate), which gives you access to a pool of existing affiliates but charges setup and override fees, or through standalone software (Refersion, Tapfiliate, UpPromote), which is cheaper but leaves recruiting affiliates up to you.
- A mid-market first year affiliate program, including platform costs and commissions paid, typically lands somewhere between $5,000 and $25,000, though the commission portion scales directly with how much revenue the program actually drives.
How Affiliate Marketing Works
An affiliate signs up for your program, gets a unique tracking link or discount code, and shares it with their audience through a blog post, a review, a coupon site listing, or a social media post. When someone clicks that link and buys something, your tracking software records the sale and attributes it to that affiliate. You then pay them the agreed commission, usually on a schedule like monthly, once the return window for that order has passed.
You are not paying for clicks or impressions the way you would with paid ads. You are paying for a completed sale. The tradeoff is that building a program with real affiliates who actually drive traffic takes ongoing recruitment and relationship management, not just flipping a switch.
What Affiliate Marketing Actually Costs
| Cost Type | Typical Range |
|---|---|
| Commission on physical products | 5% to 15% per sale |
| Commission on digital products or courses | 20% to 50% per sale |
| Self serve platform (Refersion, Tapfiliate, UpPromote) | Roughly $89 to $300 per month, flat |
| Affiliate network setup fee (ShareASale, Awin, CJ, Impact) | $500 to $3,000 one time |
| Network commission override | 20% to 30% on top of what you pay affiliates |
That last line is easy to miss when budgeting. If you pay an affiliate $100 in commission through a network, the network itself typically takes another $20 to $30 on top of that as its own fee. Standalone software does not charge this override, which is part of why smaller brands often start there instead of jumping straight into a network.
Networks vs Standalone Software
An affiliate network is essentially a marketplace. You list your program, set your terms, and publishers already active on that network can discover and apply to promote you. This solves the recruitment problem but comes at a real cost, both in setup fees and the ongoing override.
Standalone affiliate software gives you the tracking, payout, and reporting tools to run your own program, but finding affiliates is on you. For a newer brand without an existing audience of bloggers or influencers to tap, that recruitment gap is the real cost, even though the software itself is cheaper.

Content Affiliates vs Influencer Partnerships
These two get lumped together but behave differently, and the difference matters for how you structure payouts. A content affiliate runs a review site, a coupon site, or a comparison blog, and earns purely on performance. They post a link once and it can keep generating sales for years with no ongoing relationship required.
An influencer partnership usually involves someone with an active social following who posts about your product to their audience directly. These relationships often need a flat fee or a hybrid of a small upfront payment plus commission, because a single influencer post has a short shelf life compared to an evergreen blog review, and most influencers will not promote purely on commission with no guaranteed payment. Treating both groups identically in your commission structure is a common reason influencer outreach falls flat while content affiliate recruitment goes fine.
Cookie Duration and Why It Changes Your Numbers
Cookie duration is the window during which a sale still counts as coming from that affiliate after someone clicks their link, even if the purchase happens days or weeks later. A 7 day cookie means a customer who clicks today but buys in three weeks will not be attributed to the affiliate at all, which quietly kills the incentive for anyone promoting a considered purchase rather than an impulse buy.
Most ecommerce programs run somewhere between 30 and 90 days. Shorter windows suit low cost, impulse buy products where the purchase decision happens fast. Longer windows suit higher priced items where a customer might click a review, think about it, and come back later to buy.
How to Set Your Commission Rate
The most common mistake is setting a rate that looks safe on paper but is too low to actually attract affiliates. A 5 percent commission usually sits below what most active affiliates expect for a physical product, so your program can look live on the dashboard while producing almost no real activity, because affiliates are promoting a competitor paying double instead.
Work backward from your gross margin. Subtract shipping, payment processing, and any network override to get your real contribution margin per order, then set a rate that still leaves you profitable after that math, rather than copying whatever number a competitor happens to advertise.
A tiered structure often works better than a single flat rate. A base rate applies to everyone, with a higher rate unlocked once an affiliate crosses a monthly sales threshold. This rewards your best performing partners without raising costs on affiliates sending only occasional traffic, and gives serious affiliates a reason to prioritize promoting you over a competitor with a flat, uncapped rate.
Fraud and Quality Control
Affiliate programs attract a small but persistent amount of bad behavior, worth planning for before launch rather than discovering after paying out commissions you cannot easily claw back. Coupon stuffing is one of the most common issues: browser extensions that inject an affiliate’s tracking cookie without the shopper ever actually clicking their link or seeing their content, so the affiliate gets credit for a sale they had nothing to do with.
Self referral is another common pattern, where someone uses their own affiliate link to buy from themselves, or has friends and family do it, purely to collect the commission. Most platforms and networks include some fraud detection tooling, but it is worth explicitly reviewing what each option offers before choosing one, and worth writing your program terms to allow commission reversal on confirmed fraudulent activity.
Tax Reporting for US Affiliate Payouts
If you pay a US based affiliate $600 or more in a calendar year, you are generally required to collect a W-9 from them and issue a 1099-NEC at year end. Most established affiliate networks and standalone platforms handle this reporting automatically as part of the payout process, but if you are paying affiliates manually outside of a platform, this becomes your responsibility to track. Confirm this specifically with whichever tool or network you choose, since not every platform includes it by default.
Setting Up Your First Program
Calculate your affordable commission rate
Base it on contribution margin, not a number you saw a competitor use.
Choose a network or a standalone platform
Match this to whether you can recruit affiliates yourself or need access to an existing pool.
Set clear program terms
Cookie duration, what counts as an approved sale, fraud and self referral policy, and how returns affect commission payouts should all be spelled out before affiliates join. For the checkout side of this, our guide on checkout experiences and cart abandonment covers how return and refund handling affects conversion more broadly.
Integrate tracking with your store
Make sure the platform connects cleanly to your ecommerce platform’s order and inventory data so attribution and payouts stay accurate.
Recruit and activate real partners
A program with generous terms and zero active affiliates produces nothing. Recruitment is ongoing work, not a one time setup task.
If you’d rather have this built and run for you, Commerce Pundit sets up and manages ecommerce affiliate marketing programs end to end, including platform setup, commission strategy, and partner recruitment.
