3 Easy Ways to Increase Customer Lifetime Value (LTV) Using Rebuy’s Smart Flows + A/B Testing Features

This guide is designed for merchants aiming to increase Customer Lifetime Value (LTV) through Rebuy’s Smart Flows + A/B Testing tools.

Written by Diana Ibarra

🎯 Overview

Customer Lifetime Value (LTV) measures the revenue a customer generates throughout their relationship with your brand. Increasing LTV is about more than driving a larger first purchase—it requires encouraging repeat purchases, helping customers discover more of your catalog, growing recurring revenue, and giving existing customers increasingly relevant reasons to return. Rebuy’s own LTV guidance centers on strategies including subscriptions, behavioral recommendations, targeted campaigns, post-purchase offers, and Reorder Landing Pages.

Smart Flows + A/B Testing gives you a powerful framework for putting those strategies into action. Smart Flows can create different experiences based on customer context, Shopify customer tags, Klaviyo segments, and other targeting criteria, while A/B Testing helps you determine which products, recommendations, incentives, and messaging actually contribute to stronger customer behavior over time.

For LTV-focused merchants, this package becomes especially powerful when paired with Cart + Merchandising, where shoppers can interact with subscriptions, samples, Buy More Save More campaigns, cross-sells, bundles, and other personalized recommendations.

By implementing the strategies below, you can move beyond one-size-fits-all merchandising and create experiences designed around who your customers are, what they purchase, and what you want them to buy next.


👥 1. Create Different Offers for New vs. Returning Customers

Not every shopper should receive the same promotion. A customer discovering your brand for the first time may need an introductory offer or product education, while an existing customer may respond better to a new product, complementary recommendation, exclusive benefit, or replenishment opportunity.

Smart Flows includes Customer Type targeting that can route shoppers into different experiences based on Shopify customer tags or whether Rebuy identifies the current visitor session as new or returning.

  • Create a New-Visitor Experience: Introduce best sellers, samples, starter products, or another experience designed to encourage product discovery.

  • Create a Returning-Visitor Experience: Promote new products, complementary categories, exclusive gifts, or other offers designed to deepen the existing relationship.

  • Use Shopify Customer Tags: For true customer lifecycle targeting, use Shopify customer tags to distinguish groups such as VIPs, members, subscribers, or customers with other meaningful attributes.

  • Use Klaviyo Segments Where Appropriate: Smart Flows can branch based on Klaviyo segment membership. Note that Klaviyo Segment targeting within Smart Flows currently relies on Shopify account identity, so the customer must be logged in for that condition to activate.

  • Give Each Audience a Different Next Step: Rather than offering everyone the same discount, determine what behavior you want from each segment.

Example Strategy:

New Visitor

  • Introduce best sellers

  • Offer a sample or discovery product

  • Promote an introductory GWP

  • Educate the shopper on your core product line

Returning Customer

  • Recommend complementary products

  • Highlight new arrivals

  • Introduce subscriptions

  • Offer an exclusive customer-only reward

Pro Tip: Smart Flows’ built-in New Users / Returning Users conditions are based on browsing sessions—not purchase history. Rebuy considers a user returning when a session resumes after 30 minutes or more of inactivity. If your goal is specifically to distinguish first-time purchasers from repeat customers, use Shopify customer tags or another customer-data strategy rather than treating session status as purchase history.

🔄 2. Make Repeat Purchases Easy + Test What Customers Buy Next

One of the most direct ways to increase LTV is to remove friction from the repeat purchase. Rebuy’s Reorder Landing Pages are purpose-built to make reordering easier and can be incorporated into existing replenishment campaigns, including Klaviyo campaigns.

Reorder Landing Pages can also use a Data Source to control which cross-sell products appear based on the products in the customer’s previous order.

  • Enable Reorder Landing Pages: Give customers a streamlined destination for purchasing products they previously ordered.

  • Add Reorder Links to Retention Campaigns: Include personalized reorder links in email campaigns and replenishment journeys.

  • Add Relevant Cross-Sells: Configure the Reorder Landing Page Data Source to recommend products based on the customer’s previous order.

  • Prioritize Strategic Products: Use your own margin and customer-purchase data to identify complementary products that are profitable and make sense within a repeat-purchase journey.

  • A/B Test Cross-Sells on Supported Surfaces: Use Rebuy A/B Testing to compare different product recommendation Data Sources and determine which products generate the strongest engagement and revenue. Rebuy specifically supports testing different product variations through widget Data Sources.

Pro Tip: Don’t simply recommend another popular product. Ask: What is the most logical second, third, or fourth purchase after this product? Then use your merchandising strategy and experimentation to make those products easier for customers to discover.

A Note on High-Margin Products

Margin should be part of your merchandising strategy, but avoid optimizing only for margin. A high-margin recommendation that customers rarely purchase may contribute less value than a highly relevant product that leads customers into another category or repeat-purchase cycle.

Use your own profitability and customer data alongside Rebuy experiment results to find the right balance between relevance, revenue, and margin.


🧪 3. Test Buy More Save More, Subscriptions + Samples

LTV growth often comes from finding the offer that changes future customer behavior—not simply the offer that increases the current order. Use Rebuy’s experimentation tools to understand whether quantity incentives, subscription experiences, or product sampling create stronger customer relationships.

Buy More Save More

Buy More Save More encourages customers to purchase higher quantities by unlocking progressively stronger discounts. Rebuy currently supports configuring BMSM inside Smart Cart using percentage or fixed-amount discounts.

  • Test BMSM vs. Your Standard Cart Experience: Determine whether quantity incentives change customer purchasing behavior.

  • Test Products Strategically: Prioritize replenishable or frequently purchased products where buying multiple units makes sense.

  • Evaluate More Than Initial AOV: Look at whether bulk-buying changes reorder timing and longer-term purchase behavior.

Resources:

Subscriptions

Subscriptions can turn one-time purchases into recurring revenue, making them a natural LTV lever. Rebuy’s LTV guidance specifically recommends Switch to Subscription experiences as a way to build repeat revenue.

Smart Flows also supports subscription products in Add to Cart and Buy X Get Y experiences for merchants using supported Shopify Selling Plans. This functionality complements—rather than replaces—Switch to Subscription in Smart Cart.

  • Present Subscription Offers Contextually: Use Smart Flows to introduce subscription products through relevant pop-ups, campaigns, or Buy X Get Y experiences.

  • Test One-Time vs. Subscription Positioning: Compare how different benefits and messaging influence subscription adoption.

  • Highlight Real Subscription Benefits: Communicate savings, convenience, shipping benefits, or other actual advantages offered by your subscription program.

Resources:

Samples

Samples can help customers discover products outside of the category they already purchase. Rebuy’s LTV-focused Cart + Merchandising guidance recommends cross-selling or awarding samples and then retargeting customers who purchased those samples with the full-size product.

  • Test Different Sample Products: Determine which samples lead to the strongest engagement with the full-size product or category.

  • Test Free vs. Paid Samples: Compare the economics and customer response to different sampling strategies.

  • Create a Follow-Up Audience: Track sample customers in your broader customer-data or marketing strategy and introduce the full-size product later.

  • Focus on Cross-Category Discovery: Use samples to expose customers to product lines they may not otherwise explore.

Pro Tip: For LTV testing, the winning experience may not always be the one that produces the most immediate revenue. When possible, pair Rebuy experiment learnings with your broader retention data to understand which strategies create repeat customers, subscribers, and additional category adoption.


📈 Additional LTV Strategies & Use Cases

Dive Into Your Customer Data Before Building Your Offers

The strongest LTV strategies start with understanding what your best customers actually purchase. Before deciding what to recommend, examine your customer and order data to identify patterns in repeat purchasing, category adoption, subscription behavior, and product affinity.

Rebuy’s Performance Report provides a consolidated view of Rebuy-attributed sales, orders, AOV, and performance by Rebuy experience, which can help you understand which Rebuy placements are contributing incremental revenue.

Key Actions:

  • Identify Repeat-Purchase Products: Which products naturally bring customers back?

  • Identify Common Second Purchases: After purchasing Product A, what do customers commonly buy next?

  • Look for Cross-Category Movement: Which products introduce customers to additional categories?

  • Evaluate High-Value Customer Behavior: What do your highest-LTV customers purchase that lower-LTV customers do not?

  • Review Product Economics: Layer margin and profitability data into your merchandising decisions.

  • Use Rebuy Reporting for Rebuy Performance: Review Rebuy-attributed sales, orders, and widget performance alongside your broader Shopify/customer analytics.

Turn Purchase Patterns Into Recommendation Strategies

Once you identify meaningful patterns in your data, use those insights to determine what Rebuy should recommend.

Rebuy’s LTV guidance specifically recommends dynamic recommendations based on previous purchases and browsing behavior as a way to increase the likelihood of repeat purchases.

Key Actions:

  • Map Hero Product → Next Product: Define the most logical follow-up purchase for each of your highest-volume products.

  • Build Complementary Recommendation Sets: Identify products customers should discover after their first purchase.

  • Prioritize Repeatable Products: Surface products with natural replenishment or recurring-use characteristics.

  • Use Personalization Where Appropriate: Combine your own merchandising rules with Rebuy recommendation logic rather than relying on one universal recommendation strategy.

  • Test Your Hypotheses: Validate whether the product relationship you identified in historical data actually improves shopper behavior when merchandised through Rebuy.

Build VIP + Returning-Customer Smart Flows

Use Smart Flows to make your strongest customer relationships feel different from a generic storefront experience.

Key Actions:

  • Create Customer Tags: Define meaningful lifecycle groups in Shopify such as VIP, member, subscriber, or another segment relevant to your business.

  • Route Those Customers Into an Exclusive Flow: Smart Flows Customer Type targeting can branch based on Shopify customer tags.

  • Offer Relevant Benefits: Promote exclusive products, gifts, early access, or another benefit appropriate for the segment.

  • Avoid Repeating Acquisition Offers: Don’t automatically show loyal customers the same introductory incentive designed to acquire a first-time customer.

  • Test the Experience: Compare different offers or messaging to understand what resonates with your existing customers.

Resources:


Use Reorder Landing Pages as a Cross-Sell Opportunity

Reorder Landing Pages can do more than make replenishment easy. Their connected Data Source can recommend cross-sells based on the products in the customer’s previous order, creating an opportunity to expand the repeat purchase.

Key Actions:

  • Make Reordering the Primary Action: Keep the experience focused on helping the customer repurchase what they already know.

  • Add a Small Number of Relevant Cross-Sells: Recommend products that logically complement the previous order.

  • Consider Subscription: Reorder Landing Pages include an option that allows customers to switch eligible items to subscriptions from the mini cart.

  • Use Replenishment Campaigns: Link the Reorder Landing Page from lifecycle email campaigns when customers are likely to need the product again.

Test for Long-Term Value, Not Just Immediate Revenue

A test that increases today's order value isn't automatically the best LTV strategy. Some experiences—such as sampling or subscription adoption—may be valuable because of what customers do after the initial interaction.

Key Actions:

  • Define the Behavior You're Trying to Change: Repeat purchase, subscription adoption, category discovery, replenishment, or another retention goal.

  • Use Rebuy Experiments to Validate the Immediate Experience: Measure engagement, conversion, and revenue across tested Rebuy experiences.

  • Pair Results With Your Customer Data: Evaluate whether customers exposed to the strategy show the longer-term behavior you're trying to encourage.

  • Avoid Over-Interpreting Short-Term Results: Rebuy A/B tests can show which storefront experience performs better on configured experiment goals, but broader LTV analysis may require your customer and order data beyond the experiment itself.

  • Scale the Strategies That Support Both Customer Value + Business Economics.

By combining customer segmentation, repeat-purchase experiences, and systematic experimentation, you can turn LTV optimization into an ongoing merchandising strategy. Start by creating different experiences for new and existing customers, make replenishment easy with Reorder Landing Pages, and then test subscriptions, samples, quantity incentives, cross-sells, and bundles based on what your customer data tells you they are most likely to purchase next.
