Affiliate marketing and referral programmes are structurally different things, though they're often conflated:
An affiliate programme involves external publishers, content creators, and comparison sites promoting your products to their audience in exchange for a commission per sale. You have no relationship with the end customer until they buy.
A referral programme involves your existing customers recommending your store to friends and family, with both parties getting a reward when a referred customer purchases.
Both are worth implementing. Referral programmes are typically easier to set up and faster to show results. Affiliate programmes take longer to build but can generate significant volume from the right publishers.
Referral programmes on Shopify
The fastest way to activate word-of-mouth. Your existing customers are your best advocates - a referral programme gives them a tangible incentive to act on that advocacy.
ReferralCandy ($59/month) is the most established Shopify referral app. Customers get a unique referral link, share it with friends, and both parties receive a reward (discount, store credit, or cash) when a referred customer completes a purchase. Clean Shopify integration and good customisation options.
Smile.io (the loyalty app) includes referral functionality in its paid plans. If you're already running a Smile loyalty programme, the referral feature is included and worth activating rather than adding a separate app.
Common referral reward structures:
- Advocate gets £10 store credit when referral makes their first purchase
- Referred friend gets 15% off their first order
- Double-sided: both get £5 credit when the referral purchases
The double-sided reward (both parties benefit) consistently outperforms single-sided rewards in activation rate.
Affiliate programmes on Shopify
A full affiliate programme requires tracking unique affiliate links, attributing sales to affiliates, managing commission payouts, and recruiting affiliates to promote you.
UpPromote (from free) is the most popular Shopify affiliate app. Generates unique tracking links per affiliate, tracks clicks and conversions, and manages commission calculations. The free plan covers basic affiliate management; paid plans add multi-level commission structures, coupon-based tracking, and automated payout workflows.
Refersion (from $99/month) is the more established option for serious affiliate programmes. Better reporting, cleaner affiliate portal, and stronger integrations with major affiliate networks (CJ, ShareASale) if you want to list on those platforms as well.
Commission structures
Set commissions that attract quality affiliates while protecting your margin:
- Physical products: 5-15% is standard. Higher commissions attract more affiliates but erode margin. 10% is a reasonable starting point for most DTC brands.
- Digital products or courses: 20-50% is common since there's no production cost per unit.
- Subscription products: Offer a one-time commission on the first payment, or a recurring commission on each rebill. Recurring commissions attract content creators who will maintain their promotional content long-term.
Set a minimum payout threshold ($50-$100) to reduce the administrative cost of many small payouts, and a cookie window that gives affiliates credit for referrals within 30-90 days of click.
Recruiting affiliates that actually send traffic
The biggest mistake brands make with affiliate programmes is setting up the infrastructure and waiting for affiliates to find them. Active recruitment is what builds a programme.
Your existing customers. The most motivated affiliates are people who already buy from you and love the products. Email your customer list with the affiliate programme details. Customers who've left you a 5-star review are your highest-probability affiliate recruits.
Relevant content creators. Bloggers, YouTubers, and podcast hosts in your product category who have an audience that would benefit from your product. Reach out directly with a personalised message explaining why your product fits their audience - not a generic "join our affiliate programme" blast.
Comparison and review sites. Many product comparison websites in your category accept affiliate arrangements. These drive high-intent traffic because users are actively researching a purchase decision.
