Referral vs. Affiliate Marketing: When To Use Each

Referral marketing and affiliate marketing both help businesses acquire new customers via third-party advocates. Although they share the goal of encouraging sales through person-to-person recommendations, they have a few key differences and distinct benefits.

Affiliate and referral marketing are popular strategies for ecommerce businesses. Affiliate click volume has jumped more than 50% since 2020, and 87% of ecommerce brands use affiliate marketing for growth, according to Market Reports World. Referral marketing, on the other hand, has helped brands like the produce delivery service Odd Bunch increase customer retention.

In this guide, you’ll learn whether a referral marketing program or an affiliate program is right for your business. You’ll also learn about the mechanics of referral rewards and affiliate links and how to scale your marketing efforts using Shopify-integrated tools.

What is referral marketing?

Referral marketing is the process of incentivizing your current customers to share your brand with their network of friends, family, and colleagues. Referral marketing is essentially a paid version of word-of-mouth marketing, in which you reward customers for generating sales. 

The mechanics of referral programs are as follows: store owners provide their customers with unique referral links or referral codes. Customers then share these links or codes with their personal network. When a customer makes a successful referral—meaning someone makes a purchase through their link or code—both the referrer and the referee receive a reward. Common referral incentives include store credit, discounts, free products, or premium services like free shipping.

What is affiliate marketing?

Affiliate marketing is a partnership between a brand and third-party promoters, known as affiliates. Unlike referral marketing, in which the promoter is a current customer, an affiliate is an influencer or publisher with an audience. 

Affiliates promote their brand partner’s products in content such as blog posts, YouTube videos, social media posts, and articles like product roundups. They post unique affiliate links alongside this content. When a potential customer clicks a link and completes a desired action—like purchasing a product or signing up for a course—the affiliate earns a commission. 

Referral vs. affiliate marketing: Key differences

• Who promotes your brand
• Reward structures
• Reach
• Speed and scale
• Brand control

Although both referral and affiliate marketing involve third parties encouraging sales, they differ in several ways, including who promotes your brand, reward structures, and the level of control.

Who promotes your brand

In referral marketing, the people promoting your brand are satisfied customers. In affiliate marketing, the people promoting your brand are content creators with a platform. These individuals may never have bought your product before joining your affiliate network.

Reward structures

Referral rewards are designed to inspire repeat purchases and foster customer loyalty. Common incentives include store credit, loyalty points, or referral codes with cash rewards like “give $20, get $20.” 

Affiliate rewards, however, are commission-based. Affiliate marketers receive a percentage of the sales they generate.

Reach

Referral marketing taps into customers’ personal networks. A customer might refer only a few friends and family members, but these are personal recommendations—the referrer may know that the referee needs or is looking for such a product, and the referral acts as social proof. On the other hand, affiliate marketing depends on high reach. An affiliate might share a link with 100,000 followers, but those customers may not know to what extent the affiliate recommends or uses the product themselves.

Speed and scale

By recruiting high-performing brand ambassadors with large followings, brands can acquire new customers quickly. Referral marketing requires a more gradual approach, since you can scale only as your existing customer base grows.

Brand control

Referral marketing allows for tighter brand control because the referral message is often shared via pre-written templates. These often appear as pre-filled email drafts or SMS messages that customers can send in a few clicks. By providing the exact wording for the offer, businesses ensure the message stays on brand and remove the need for the customer to write their own pitch. 

In affiliate marketing, however, affiliates promote products using their own creative style. This allows for diversity in a brand’s marketing efforts but requires brands to carefully vet their affiliate relationships to ensure their partners adhere to overarching brand guidelines.

When ecommerce brands should use referral marketing

• You have an engaged customer base
• You want to focus on customer retention
• You want to build community throughout the supply chain

Rather than buying attention through ads, referral marketing allows companies to build a growth framework around the organic enthusiasm of their customers and partners, turning word of mouth into a measurable and scalable business asset. Here’s when to consider referral marketing:

You have an engaged customer base

If your customers are already telling you they love your product, you have the foundation for a successful referral program.

Divy Ojha of Odd Bunch says on Shopify Masters that this foundation was the primary driver of his business for nearly a decade. “For the first seven years of our business, that’s the way we grew,” he says. “As consumers were having a good experience, they were telling the person down the road, they were telling their friends, they were telling their colleagues.” 

As paid media becomes more competitive, Divy explains that activating your existing community is a more sustainable path to growth. “It’s so much more powerful to try and activate that and turn them into brand advocates that continue to drive that vehicle forward.”

If you’re on Shopify, a few features can help you set up a referral program quickly:

• Discount codes. This is a native Shopify feature for creating shareable referral codes. You can manually distribute unique discount codes to happy customers to power an informal referral strategy.

• Third-party referral apps. Tools like Smile and Referral Candy integrate with Shopify Flow to automate referral rewards. For instance, when a referred friend makes a first order, Shopify Flow can instantly trigger a “thank you” credit for the original referrer.

You want to focus on customer retention

As Divy says on Shopify Masters, the referral behavior itself cultivates customer retention. “Referrals in the first four weeks are what we found to be a killer metric,” Divy says. “It’s a predictive metric of retention.” 

By mobilizing loyal customers early, Divy built an acquisition pipeline that generates new customer revenue at zero customer acquisition cost (CAC) while simultaneously cultivating customer loyalty.

Divy’s team operated on the idea that when a customer approaches someone else to try the product, they essentially become a brand champion. “The hypothesis was that if someone feels they’ve now become a champion for the brand or have convinced someone to do something that they themselves started doing, there would be that extra stickiness,” Divy says. 

Odd Bunch tested this hypothesis, and the results bore out. “Their retention at six months was an order of magnitude higher,” Divy says. 

You want to build community throughout the supply chain

The benefits of referral marketing can extend beyond customer acquisition to include business-to-business (B2B) growth and supply chain resilience. 

Sara Von, founder of the olive oil brand Citizens of Soil, used a B2B referral strategy to scale her network of producers while maintaining strict sustainability and quality standards. 

On Shopify Masters, Sara explains that her existing producers are often the best scouts for new partners because they already understand the brand’s requirements. “We financially incentivize [our producers] to refer other producers, and they know my checklist because they’re just as strict,” she says. “We’re really using our network of farmers to expand the network of farmers, and have them as almost regional heads.”

When ecommerce brands should use affiliate marketing

Affiliate marketing lets companies reach new potential customers quickly. Here’s when to consider using an affiliate marketing strategy:

You want to build brand connection online

Affiliate marketing lets brands tap into their affiliate partners’ communities. 

Pia Mance, founder of jewelry brand Heaven Mayhem, restructured her 2026 marketing strategy to prioritize this type of connection over traditional media buying. “I personally want to lean more into influencer and community rather than ad buying,” she says. “I think it’s a better way to acquire a customer, and I personally would rather buy something from an influencer talking about it because I associate them with knowing good things, and then I have more attachment to the brand rather than just seeing an ad.” 

The key is finding creators who are true fans of your brand. Laura Thompson, cofounder of natural skin care brand Three Ships, uses a seeding strategy to ensure authenticity. The company sends content creators free products with no strings attached. If creators post about the items on their own, Three Ships knows they genuinely like them.

“That works very well, because it’s authentic,” Laura says on Shopify Masters. “Once they post, we’ll then set them up with an affiliate code for them to start earning commissions.”

Shopify store owners can use Shopify Collabs to manage influencer seeding and run their affiliate marketing programs. The free app simplifies recruiting creators, tracking affiliate links, and managing automated payments. 

You want a results-based marketing strategy

Affiliate marketing provides immediate clarity on which efforts are actually converting. Instead of paying for general exposure, you can track exactly which partners are driving sales volume in real time. 

Heaven Mayhem founder Pia says that moving to a trackable affiliate model was a pivotal step in building her $10 million accessories empire. “It has changed our business, and the metrics are amazing because you can really see who is driving the volume, instantly,” she says.
