Launching an eCommerce referral program is a highly effective way to increase sales, improve customer retention, drive product adoption and skyrocket customer lifetime value (CLV). This is because consumers respond more positively to word-of-mouth marketing practices — like customer referral programs — than they do other traditional forms of advertising.

And though this fact is widely understood by marketing professionals, many don’t feel that they’re doing it very well. According to research released by the Word of Mouth Marketing Association (WOMMA) and the American Marketing Association (AMA), 64% of marketing executives said they believe word-of-mouth is the most effective type of marketing. Only 6% say they felt as though they’d mastered it. 

eCommerce brands that are able to formalize and optimize their customer referral programs and other word-of-mouth marketing initiatives have a clear edge over competitors. And accomplishing these tasks is not as difficult as many marketing executives seem to think.

What Is an eCommerce Referral Program? 

An eCommerce referral program is a marketing initiative that taps into your existing customer base to reach more potential buyers who may be a good fit for your products or services. Customers who refer their friends (commonly called “advocates”) to your business receive a reward once a purchase is made or other valuable action is taken (such as signing up for a newsletter or downloading an app). Generally, the friend that was referred also receives some type of reward. 

What exact actions trigger rewards, and what those rewards are, is entirely up to an individual business, though it should be noted that there are some best practices that can be broken down by industry vertical. For example, for cosmetic products, a referral offer of “Give $20, Get $20” works better than offering discounts as a percentage (e.g., 50% off). 

The Benefits of an eCommerce Referral Program

Thinking of and treating your customers as a marketing channel opens up a world of possibilities for your team. When deployed effectively, a customer referral program can produce immediate and tangible benefits for brands that rely primarily on eCommerce to drive sales.

Referral program benefits include:

Increased Average Order Value (AOV)

What it is: 
A critical metric for any eCommerce business to track, AOV measures the average total value of orders placed by customers over a certain period of time.

How an eCommerce referral program improves it: 
Depending on which marketing channel has brought a customer to the point of purchase, customer AOV can vary highly. Customers that have engaged a business through a referral program tend to have an increased AOV when compared to regular customers due to the fact that they are usually a very good fit for the products or services on offer.

Higher Purchase Frequency  

What it is:
Purchase frequency refers to how often customers make purchases from a particular online store within a given time frame. 

How an eCommerce referral program improves it: 
Since referral programs incentivize your existing customer advocates by rewarding them with discounts and gift cards, they are much more likely to make frequent purchases than other customers.

Improved Customer Lifetime Value (CLV)

What it is:
Customer Lifetime Value (CLV) represents the long-term revenue potential associated with a customer's relationship with a business. 

How an eCommerce referral program improves it: 
As customer retention improves, CLV typically increases due to prolonged patronage and repeated purchases. Studies have shown that even a small increase in customer retention can significantly boost a company's profitability over time.

Better Net Promoter Score (NPS)

What it is:
NPS measures a customers' likelihood to recommend a brand to others. It reflects customer satisfaction and loyalty, with higher scores indicating stronger advocacy.

How an eCommerce referral program improves it: 
Rewarded customers are happier customers; and happier customers lead to higher a Net Promoter Score (NPS). By building a comprehensive eCommerce referral program, you can ensure that there are more “promoters” among your customer base, and can therefore expect a relatively strong NPS compared to competitors.

Decreased Churn Rate

What it is:
Customer churn rate refers to the percentage of customers who stop purchasing from an online store within a specific period. 

How an eCommerce referral program improves it: 
Referral programs help keep existing customers engaged with a brand and enrich the relationship between seller and buyer. This extends the average relationship between a customer and brand and decreases the average churn rate as a referral program grows. 

Lower Cost per Acquisition (CPA)

What it is:
Cost per Acquisition (CPA) refers to the expenses incurred in acquiring new customers. Generally, it is used to measure the effectiveness and efficiency of marketing campaigns.

How an eCommerce referral program improves it: 
Typically, eCommerce companies that deploy referral programs experience a much lower CPA through their word-of-mouth marketing efforts than through any other channel. 

How To Launch an eCommerce Referral Program

Though the fine details of a customer referral program will vary depending on the type of eCommerce company running it, there are a few consistent elements to keep in mind as you plan out your program. 

Identify Potential Advocates & Ambassadors

Before you start your program, it’s important to put together a strategy for identifying, targeting and engaging your current customers who are most likely to participate in a refer-a-friend program. This primes the pump so that when your referral program officially launches, you already have a group of loyal customers ready to start spreading the word about your business.

Here are a few tactics you may consider when completing this step in building a referral program: 

  • Monitor customer reviews: By keeping a close eye on your customers reviews, you’ll be able to spot the customers who are already raving about your brand online and most ready to become brand ambassadors. 
  • Look at purchase histories & data: One easy way to identify potential brand champions is to find customers that have made frequent or recent large purchases. These customers clearly are highly engaged with your business and it can be assumed they’d be very excited to be rewarded for sharing your products or services with their friends. 
  • Check social media: It’s more than likely that customers who would be willing to advocate for your brand are already doing so online. A company’s social media pages and online forums can be a great place to identify brand advocates and promote your referral program.

Choose Your Implementation: Build, Buy or Partner 

When building a referral program for your eCommerce business, it’s important to think through your implementation strategy early. There are essentially three ways to get a referral program up and running: 

  • Build it yourself: If you have the capacity, you may opt to start from scratch and launch your referral marketing program entirely on your own. This means creating the software tools needed to run the program, including things like fraud prevention mechanisms and automated incentive delivery. This route is only really recommended for teams that have significant development resources and the time to bring the program to fruition.

  • Purchase referral marketing software: Purpose-built referral program software platforms, such as Friendbuy, can make it much easier for marketing teams to run a successful eCommerce referral program. These SaaS tools typically provide a variety of robust features such as:
    • A flexible design editor
    • Referral stats & analytics 
    • Customizable earning actions & events
    • Built-in A/B testing
  • Partner with a team of referral marketing experts: Though dedicated referral marketing software can make it much easier to operationalize word-of-mouth marketing, the best way to ensure success is to partner with an experienced team of referral marketing experts to craft the ideal program for your brand. These teams can help you determine everything from the proper placement of banners to the type of incentives that should be given to advocates and their friends. For example, Friendbuy’s Customer Success Team has helped many top brands across all types of industries drive up to a 25x ROI from their eCommerce referral programs.

Seamless Integration

To create a referral program that scales, ensure yours is seamlessly integrated into your email and SMS marketing efforts. Ideally, if you’re using referral marketing software, it should be quite easy to integrate your email, SMS & push technology such as Klaviyo, Attentive, Iterable, Cordial and Braze to make the referral process easy and visible to your customers.

Add Call-to-Actions Everywhere

If you want your referral program to catch fire with your audience, it’s key to ensure the program is promoted across nearly every touchpoint that exists between you and your customers. Incorporate referral call-to-action banners into every email you send, place them strategically across your site, add them to the checkout page, and it’s even a good idea to create a dedicated referral program landing page where customers can see the rules and details of your program. This provides a constant reminder for customers to refer their friends and family and receive awesome rewards in exchange. 

Provide Incentives That Matter

It’s important to offer enticing rewards that will resonate with your customers to incentivize referrals. What these incentives look like is entirely up to you, but it’s important that they provide something both advocates and the friends they share your brand with will find value in. 

For example, these incentives may take various forms, such as discounts, exclusive access to upcoming features or products, or even monetary rewards for referrals (e.g. "Give $20, Get $20"). This alignment is key to optimizing the impact of your program.

Consistent Communication

Regularly remind your customers about your referral program. Send dedicated referral emails and texts to all customers to keep them engaged and aware of the benefits of referring others, with specially carved out emails for those that are most likely to engage in the program., 

By implementing these strategies, eCommerce companies can increase the visibility of their referral program and encourage consistent engagement from their customers to drive ongoing revenue for their brands.
