In this post, we shall cover:

6 eCommerce Brands Acing Referral eCommerce Strategy (+ Tips)

Top Referral Marketing Metrics to Track 

How to Create a Referral Marketing Program that Really Works

6 eCommerce Brands Acing Referral eCommerce Strategy (+ Tips)

1. Loop all first-time customers into the referral marketing program

Here’s the thing: When shoppers are busy comparing, considering, exploring and even buying, referring the brand to people they love isn’t on the priority list. 

Unless the brand gives them a memorable nudge around it. 

Tumble’s Referral Marketing Strategy

One eCommerce brand that has aced its referral marketing strategy by looping in first-time customers is Tumble, a store that sells rugs that are handmade and designed exquisitely. 

Their word-of-mouth marketing strategy creates an ease for existing customers, who’re still in the early stages of feeling excited about buying from the brand.

This also makes them the perfect audience for referring without taking the brand for granted (as more long-term loyal customers can do). 

There’s also that other thing about plugging referral leaks that this process ensures, since all first-time customers are absorbed into it anyway!

Moreover, each referrer gets a unique referral link that they can refer up to 3 friends / family members with - this rule ensues Tumble doesn’t have to deal with referral link abuse.

When we did a deeper evaluation, we also noticed several other features that help Tumble’s referral strategy take flight:

👉 Excellent self-help resources across the site: This not only includes an FAQ that covers the entire customer journey (and maps objections accordingly), but also visualization tools & complimentary design consultations.

👉 Free shipping & returns within US: In combination with their buy now pay later methods, this ensures more referred folks actually feel pulled to make first-time purchases (and being absorbed into the program automatically).

2. Use referral marketing to drive subscription buys

Word-of-mouth marketing is a potent way to cut out extra spends around acquiring new customers. 

And this becomes an additional leverage for subscription orders, which can create hesitation in most shoppers.

Lovevery’s eCommerce Referral Strategy

They do this seamlessly: when it comes to rewarding the referrer and the referred, they don’t stop at giving $20 — they make sure this amount is directly tied to their Play Kit subscriptions. 

This is a great way to push existing customers towards repeat purchases and for the newly referred to become first-time customers.

What works even better is that the brand is conscious about not letting referral credits lapse. Similarly, Lovevery doesn’t put impositions on how many referral credits a single customer can earn. 

And that means, someone who gets repeated successful referrals, has a chance to try out an all-new subscription kit for themselves.

However, the structure of their referral marketing strategy is just the icing on the cake — there are other aspects that the brand optimizes, which make referrals super compelling:

👉 A powerful content strategy: Be it the product photography they invest in or the value-add educational material they send through their emails, Lovevery has created a strong ground for their referral strategy to bear fruit.

👉 Thoughtful UGC on social media: Unlike many other brands, this one chooses to showcase very small-time creators as long as their content is thematically and philosophically in tune with Lovevery.

3. Create referral nudges for the entire customer lifecycle

Come to think about it, many brands fail at referral marketing because they don’t optimize their strategy for the entire conversion funnel. 

When referral nudges show up at peak points of decision-making across the customer journey map, adoption, engagement and conversions improve.

Olive and June’s Referral Strategy

First of all, they show their double-sided referral incentive very clearly on their website, close to the footer. 

When people click, they’re able to access a unique referral code link, paired with an instantly generated message that one can edit. 

Alongside, Olive and June makes sure their referral marketing widgets go into their emails as well, whether they’re welcome emails or product recommendation emails.

This in fact enables the brand to create unique email campaigns for both referrers and referees. 

However, what really raises the bar of Olive and June’s referral marketing strategy is that all referral credits go towards the purchase of “Systems” or curated manicure bundles that mimic a high-quality (high-priced) salon visit.

See it closely and you realize that their referral strategy is not standing all by itself — to spruce it, the brand also features:

👉 A robust membership program: From DIY content to 10% off on all orders and exclusive sneak-peeks, Olive and June’s membership program is all about satisfaction — and satisfied members only mean more referrals!

👉 Exhaustive educational resources: The brand runs “Olive University” that focuses on offering content for shoppers across the lifecycle and with different kinds of intent.

4. Expand your referral program beyond usual customers

Like it or not, referral network saturation is a reality — especially in cases where the referral marketing strategy doesn’t find sustained integration with other parts of the larger marketing strategy. 

eCommerce brand Olaplex decided to take care of this by expanding its original referral base. 

Olaplex’s Referral Program Explained

Thanks to the brand’s pro site for professionals, it began to allow stylists and salon specialists to refer their clients. 

This ties in well with the fact that the brand, while offering double-sided incentives, has never been one for dollars or points.

Time and again, it has promised a free product both to the referrer and the referee. 

At one time, it was the N°0 + N°3 hair maintenance kit, while at another it was their moisture mask. 

By integrating various products into the referral system, the brand manages to inspire more referrals across different points in time. 

However, Olaplex maintains several other brand assets that directly feed into their referral eCommerce marketing:

👉 A well-known ambassador program: The brand features highly influential global ambassadors, who’re also stylists and colorists of the first order — and this supports their referral marketing efforts really well.

👉 Year-round offers on bestsellers: More people are naturally inclined to redeem their free referral gift because the brand runs attractive discounts around the year on bestselling products.

5. Create unique gamified referral challenges 

Static referral marketing is often what eCommerce shoppers are used to—and this can have a detrimental effect not just on adoption but on keeping a program like this afloat. 

The way out of this is to create gamified referral challenges that make both referee and the referred sit up & take notice. 

Strava’s Referral eCommerce Strategy

One of the most successful examples of gamified referral marketing in eCommerce is of Strava - their “Get a Friend to Run” was a high-stakes challenge where a referee could invite the friend to the challenge. 

And if the friend completed their first run within a week, both referrer and referee could enter a draw where Strava products could be won. 

Similarly, in their “Get Sponsored by the Feed” challenge, users can participate in specific fitness activities for set periods of time and unlock $60 from The Feed to spend on nutrition products. 

While these challenges are obviously challenging, they’re super easy for existing users to share with their friends and family. 

The brand is able to keep up with their referral strategy for several other strong reasons:

👉 Activity sharing within the Strava community: This aspect of the brand’s community-building efforts ensures that active users remain an inspiration to their friends and family, who in turn are drawn to these challenges.

👉 Digital badges & accolades: Along with leaderboards, these visual nudges can be inspiring for people who’re yet to be a part of the referral marketing community.

6. Combine referral & influencer marketing smartly

Giving your referral eCommerce marketing the influencer twist can be the ultimate gamechanger. 

And what’s really great is a referral & influencer marketing combination that can run in parallel to your usual referral program where customers bring in friends and family. 

With influencers stepping into the fray, numbers usually blow up (example) and for all justified reasons.

After all they have a huge sway over their followers, who’re more likely to buy if their favorite influencer suggests it. 

This is something Thrive Causemetics leverages wholeheartedly. 

Thrive Causemetics’ Referral Marketing Strategy

The brand runs influencer giveaway alerts from time to time, depending on their existing customer base to refer / tag people they know. 

The prizes they declare are usually product bundles, so that the winning referee can have a more thorough sense of Thrive’s offerings. 

The usual refer-a-friend model is embedded into their larger loyalty system.

This helps adopters find a number of actions to continue their engagement and build their points (for referrals, they make 1500 points!)

This is how Thrive Causemetics collaborated with @healsquad to declare the Thrive Causemetics Vault Collection to be the one winning from across referees, for their 10th anniversary.

Factors that help Thrive Causemetics’ referral strategy to keep growing include:

👉 Strong integration with their mission: Cause marketing is a huge part of the brand’s background process, and people who get referred and share the same value system, end up wanting to buy.

👉 An affiliate program that attracts top notch influencers: Thrive has its affiliate program put up on various sites (like this one), drawing in beauty influencers across the world who reflect audiences in sync with the brand’s values.

Top 5 Referral Marketing Metrics to Track 

While there are 15-odd referral marketing strategy metrics for eCommerce growth that you can track, you want to put over 50% of your focus on the following (and we’ll tell you why):

✔ Referral Conversion Rate

THE most important metric to track is the referral conversion rate — because referral marketing leads typically have a 30% higher conversion rate than leads from other channels.

A high referral conversion rate indicates a genuinely engaged audience and compelling referral process.

The flip side of a poor referral conversion rate. On the other hand, low referral conversion rates might indicate poor targeting, friction in the referral process, or misaligned incentives.

This metric helps you optimize both who your customers are referring to and how you're converting those referrals.

How to calculate: To get the percentage, divide total number of referral purchases by total number of referral shares and multiply it by 100. 

✔ Customer Lifetime Value

It’s a fact that high-intent shoppers who come through referrals tend to spend 15% to 25% more on their first purchase than those who come from other channels.

They also tend to engage with a brand 37% longer than other shoppers.

And that’s what makes this metric crucial for budget allocation decisions.

If referred customers have 50% higher CLV, you can justify spending more on referral rewards and program optimization.

It also helps you identify whether your referral program is attracting high-quality customers who stick around and purchase more over time, or just bargain hunters attracted by referral discounts.

How to calculate: To get to CLV, (Average Purchase Value × Purchase Frequency) × Average Customer Lifespan

Here 👉

Average Purchase Value = The average amount a customer spends on an order, which can be derived from dividing total revenue by total number of orders.

Purchase Frequency = This measures how often a customer makes a purchase within a set period, which can be derived by dividing the total number of orders by the total number of unique customers.

✔ Referral Program ROI

This is a key referral eCommerce marketing metric because shoppers who come through referrals bring in 25% higher profit margins.

The ability of referral programs to bring high-value customers automatically improves ROI.

A healthy referral ROI should be at least 3:1, meaning every dollar spent generates three dollars in revenue.

This metric helps you make strategic decisions about scaling your referral program and adjusting reward structures.

How to calculate: Subtract program costs from referral revenue and then divide by program costs. To get the percentage, multiply the earlier value with 100. 

✔ Referral Participation Rate

Calculate by dividing active referrers by total eligible customers (usually customers who have made at least one purchase).

Low participation rates (under 5%) suggest poor program awareness, complicated processes, or insufficient motivation. High participation rates (15-25%) indicate strong program-market fit and effective promotion. 

How to calculate: To arrive at the percentage, divide the number of customers who referred others by total number of customers in the referral program, and then multiply this value with 100. 

✔ Referral Viral Coefficient

This metric is crucial for understanding your program's growth potential and network effects.

It helps you identify whether your referral program can drive sustainable, compounding growth or just provides incremental customer acquisition.

How to calculate: It's calculated by multiplying your referral participation rate by your referral conversion rate by the average number of referrals per participating customer. A viral coefficient above 1.0 means your referral program is generating exponential growth.

How to Create a Referral Marketing Program that Really Works 

Your referral marketing strategy will yield results based on the structure you give it - here are 5 critical aspects to remember:

👉 Let both sides win - Tailor the rewards based on where the customer is in their journey - loyalty buyers might want store credit; new buyers might respond better to % off.

👉 Make it easy to share - ensure you feature:

• 1-click share buttons (WhatsApp, SMS, Instagram DMs)
  
  
• Dynamic tracking (user sees how many referrals they've made)
  
  
• Mobile-first design — most sharing is phone-based

👉 Nudge potential referrers when they’re emotionally primed - and see to it that this is done differentially across the customer journey map:

Awareness Stage: Referral Tactic - “Unlock Early Access by Referring”

Consideration Stage: Referral Tactic - “Refer to Earn, Even Before You Buy”

Purchase Stage: Referral Tactic - “Get a Freebie on Your Next Order by Referring”

Post-purchase Stage: Referral Tactic - “Turn Your Purchase Into Perks - Refer Friends When Your Order Reaches You”

Loyalty Stage: Referral Tactic - “VIP Referrers Get Access to Secret Drops”

👉 Create a clear progression ladder - The upward movement creates momentum and anticipation, and when you add smart gamification elements, just adopting the referral program feels rewarding!

👉 Integrate with your loyalty and / or affiliate program - Referral marketing performs 2–3x better when connected to customer lifecycle touchpoints.
