In the ever-evolving landscape of advertising, brands are constantly seeking innovative and effective ways to connect with new customers and drive sales. One increasingly powerful tool gaining significant traction is the card-linked offer (CLO). This unique approach to customer acquisition leverages real-time purchase data to deliver targeted offers directly to consumers through their payment cards, creating a seamless and impactful experience.

CLOs are rapidly becoming a key driver for both online and in-store transactions. Their effectiveness stems from the ability to tap into actual consumer spending habits, providing advertisers with a level of precision and insight often unmatched by traditional channels. By analyzing past customer purchase behavior, brands can identify and target high-value, in-market audiences with relevant offers, fostering a higher likelihood of conversion and repeat business.

What Makes CLOs a Game-Changer?

Compared to conventional performance marketing tactics, CLOs offer several distinct advantages:

• Data-Driven Precision: CLOs provide access to rich, deterministic purchase data, eliminating the reliance on probabilistic estimations. This allows for highly accurate targeting of specific consumer segments based on their actual spending patterns.
• Measurable Incrementality: One of the most compelling benefits of CLOs is the ability to accurately measure the incremental impact of marketing campaigns. By establishing clear test and control groups based on historical purchase data, advertisers can gain a true understanding of the uplift generated by their offers.
• Fraud-Free and Brand-Safe Environment: Operating within the secure infrastructure of financial institutions, CLOs offer a 100% bot and fraud-free environment, ensuring that advertising spend reaches genuine consumers.
• Omnichannel Reach: CLOs are effective in driving both online and in-store sales, providing a unified approach to reaching consumers regardless of their preferred shopping method. This omnichannel capability is crucial in today's interconnected marketplace.

The Evolution of CLOs: Trends Shaping the Future

The landscape of card-linked offers is continuously evolving, driven by advancements in technology and a deeper understanding of consumer behavior. Key trends shaping the future of CLOs include:

• Enhanced Personalization: Leveraging the power of machine learning, CLOs are becoming increasingly sophisticated in delivering hyper-personalized offers tailored to individual consumer preferences and predicted future needs.
• Deeper Data Integration: The integration of CLO platforms with CRM systems and data connectivity partners enables advertisers to layer their own first-party data with transaction insights, leading to even more refined targeting and a holistic view of their customers.
• Expansion into New Verticals: While traditionally strong in sectors like dining, retail, and travel, CLOs are expanding their reach into new and unexpected industries like the auto industry, demonstrating their versatility and broad applicability.

Building Brand Loyalty Beyond the Transaction

The power of CLOs extends beyond simply driving a single purchase. By strategically utilizing targeted offers and understanding customer behavior, brands can foster long-term loyalty. CLOs enable businesses to re-engage lapsed customers, incentivize repeat purchases, and cultivate stronger relationships with their most valuable consumers.

Cardlytics and Qualtrics recently partnered to survey shoppers and evaluate the perspective of customers who leverage card-linked offers. Unsurprisingly, the survey found that CLOs create a more rewarding experience for shoppers and can act as that critical tipping point to influence purchase decisions.

In fact, the data shows customers spend more with card-linked offers in-hand:

• 60% of customers engage more with card-linked offers when their finances are tight
• 64% agree that having card-linked offers encourages them to spend more per transaction
• 72% of customers are more likely to spend with a brand that offers card-linked rewards 

Integrating CLOs Into Your Advertising Strategy

While CLOs offer significant potential, advertisers must understand how they fit into their broader strategy. As the lines between traditional affiliate marketing and CLOs become increasingly blurred through greater network integration, a unified approach is emerging. However, it's crucial to recognize the unique attribution models associated with CLOs, which often focus on overall incremental lift rather than last-click attribution.

Navigating the CLO Landscape: Key Considerations

For brands considering implementing a CLO program, several factors are crucial for success:

• Understanding the Nuances: It's vital to recognize how CLOs differ from traditional affiliate marketing and understand their specific capabilities and limitations.
• Strategic Budgeting: Carefully consider the pricing models associated with CLOs, whether it's a cost-per-acquisition model or funding the offer directly.
• Focusing on Incrementality: Shift the focus from simple return on ad spend to measuring the true incremental return generated by CLO campaigns.
• Leveraging Data Wisely: Tap into the rich data insights provided by CLO partners to refine targeting, personalize offers, and understand customer behavior.
• Embracing Testing: Like any effective advertising channel, experimentation is key to unlocking the full potential of CLOs.

The Future Is Linked

Card-linked offers represent a powerful evolution in customer acquisition and engagement. By harnessing the wealth of purchase data available, brands can connect with consumers in a more relevant, personalized, and measurable way.

Airlines: Unpacking the State of Customer Loyalty

Introduction

In our previous report, Redefining Customer Loyalty, Cardlytics defined loyalty as a consumer’s preference for a merchant over its competitors. We analyzed $160B in spending across six industries to measure customer loyalty and spending patterns with both loyal and non-loyal customers.

But customer behavior isn’t fixed—customers shift between loyalty segments over time. Understanding these shifts helps identify churn and informs strategies to nurture relationships and move customers to higher loyalty segments. In our Loyalty Movement Report, we dive into the Airline category to better understand engagement over time by the entire more than $58B in consumer spend behavior.*

Airline Category Loyal Customers

On average, 39% of a merchant’s customers are not loyal. Yet the loyal segment shows extreme loyalty when it comes to share of wallet (95%) where as a not loyal segment does not (28%).

Top Customers (top 10% of most frequent transactors) are heavily loyal - 2/3. And that loyal customer segment shows the same extreme loyalty in terms of share of wallet as all customers.

Findings

We looked into purchase data at all Airlines in the US over the last 8 quarters (Q1-23 through Q4-24) on a quarter by quarter basis to see whether even the “most loyal” customers showed changes in their purchase behavior. 

Airline Loyalty Movement

Overall, quarter over quarter, customers tend to stay in their same segment (36%) while there is an equal amount that increase/decrease loyalty (7%) and are either new or lapsed (22% and 26%, respectively). However, when digging into the individual segments, the opportunity becomes more clear among segments that are categorized as non-loyal. 

Segment Movement

Of the ⅔ of each customer segment that is non-lapsed, those that are loyal to a specific airline tend to stay loyal (57%). However, those categorized as “non-loyal” (Tied/Prefer) show significant willingness to to shop around (43% and 46%, respectively).  

Airline Leaky Bucket

Airlines are acquiring new customers yet even more existing customers are moving into the lapsed tier. This cycle is expected based on typical consumer behavior for airline travel quarter over quarter but reinforces need to nurture existing relationships .

Diving deeper into the individual segments tells us:

• Loyal customers typically do not switch airlines, which is most likely due to airlines robust loyalty programs and incentives. However, customers that are Tied or Prefer have a high propensity for behavior change and show an opportunity for targeted campaigns to influence their behavior.
• Lapsed customers are similar across all segments, which is reflective of typical airline purchasing behavior - regardless of their loyalty categorization.

Definitions of Customer Segments

‍
Loyal Customers
Loyal: Only shop with a specific brand, or have the highest share of wallet with a given brand and relative rank is lower than all other brands in consideration set

Not Loyal Customers
Tied: Similar relative ranks to 2 or more brands regardless of share of wallet ranking
‍Prefer: Lower share of wallet and higher rank than other brands in their consideration set
‍Lapsed: Shopped historically but do not shop currently, as defined by the analysis time period
‍New: Shop currently but have not shopped historically, as defined by the analysis time period

Takeaways

Airline marketers’ inherent focus on nurturing loyal customers is well-know and consumer spend data show it’s working - Loyal customers tend to stay loyal. But huge opportunity exists with customers who are not loyal to any specific airline and could be lured through greater incentives. To stay top of mind, marketers must continuously nurture relationships, understand customer needs, and offer seamless experiences. To foster loyalty with your customers, consider these recommendations:

• Use an “always on” strategy to keep customers engaged, regardless of purchase frequency.
• Regularly update/refine customer segments and adjust reward offers to keep them engaged.
• Use targeted campaigns to boost loyalty and revenue.

Introduction‍

In our previous report, Redefining Customer Loyalty, Cardlytics defined loyalty as a consumer’s preference for a merchant over its competitors. We analyzed billions in spending across six industries to measure customer loyalty and spending patterns with both loyal and non-loyal customers.

But customer behavior isn’t fixed—customers shift between loyalty segments over time. Understanding these shifts helps identify churn and informs strategies to nurture relationships and move customers to higher loyalty segments. In this Report, we dive into customer behavior in the QSR category to better understand engagement over time by analyzing more than £5.8bn in consumer spend behavior.*

Findings: loyalty is fluid, not fixed 

We looked into purchase data at all QSRs in the UK over the last 8 quarters (Q1-23 through Q4-24) on a quarter by quarter basis to see whether even the “most loyal” customers showed changes in their purchase behavior. 

‍QSR Loyalty Movement

‍Overall, quarter over quarter, 36% of customers tend to remain in their existing segments and 26% increase or decrease their loyalty to a merchant, showing that QSR customers tend to be more promiscuous than other industries. Also, there is much more extensive customer loyalty movement within the “not loyal” segments. 

‍Findings: segment movement 

Diving deeper into the individual segments tells us:

• Loyal customers are the most stable, with 58% staying Loyal.
• Prefer customers also show strong retention — 52% remain in that segment.
• Tied customers are the most fluid — only 10% stay Tied, while 58% shift into Loyal or Prefer.
• Churn risk is highest for Prefer customers, with 35% lapsing — nearly 2x higher than Loyal customers (20%).

‍Segment movement
‍
Customer movement is happening across all segments, but the Tied group shows the highest churn – only 10% remain Tied, while a combined 58% shift into either Loyal (32%) or Prefer (26%). This volatility signals an opportunity to convert mid-loyalty shoppers with targeted interventions.

QSR Leaky Bucket 

QSR brands are losing customers faster than they are acquiring them – with Lapsed customers (22.3%) outpacing New customers (15.9%). This signals a need to strengthen retention strategies to prevent long-term erosion of customer loyalty.

Takeaways: It’s more costly to acquire or re-acquire customers than to keep existing ones engaged. 

Our analysis shows that 22% of QSR customers have lapsed, outpacing the 15.9% of new customers being acquired. Brands are at risk of net customer loss unless they prioritise loyalty-building efforts.

Our segment movement data also reveals that “Tied” customers are the most fluid, with 90% shifting into other behaviours — with both gains and losses. In contrast, Loyal customers remain relatively stable, and Prefer customers show moderate retention.

To protect and grow market share, marketers must go beyond acquisition. Nurturing relationships and strengthening loyalty can have a direct impact on retention and revenue. 

To foster loyalty, consider these recommendations:

• Deploy an “always-on” strategy to stay connected with customers, regardless of purchase frequency.
• Continuously refine customer segments and tailor reward structures to reflect shifting behaviours.
• Launch targeted campaigns focused on converting fluid segments (like Tied and Prefer) into Loyal customers.

The Secret Sauce to Retaining Customers

‍
‍Introduction‍

In our previous report, Redefining Customer Loyalty, Cardlytics defined loyalty as a consumer’s preference for a merchant over its competitors. We analyzed $160B in spending across six industries to measure customer loyalty and spending patterns with both loyal and non-loyal customers.

But customer behavior isn’t fixed—customers shift between loyalty segments over time. Understanding these shifts helps identify churn and informs strategies to nurture relationships and move customers to higher loyalty segments. In our Loyalty Movement Report, we dive into customer behavior in the QSR category to better understand engagement over time by analyzing more than $44B in consumer spend behavior.*

QSR Category Loyal Customers

On average, 81% of the category’s customers are not actually  loyal to any brand. But the loyal segment has a much higher share of wallet (67%) than a not loyal segment (15%).

Top Customers (top 10% of most frequent transactors) are show  reverse allegiance vs overall customers. And the loyal customer segment shows more than 3x higher share of wallet.

Findings

We looked into purchase data at all QSRs in the US over the last 8 quarters (Q1-23 through Q4-24) on a quarter by quarter basis to see whether even the “most loyal” customers showed changes in their purchase behavior. 

QSR Loyalty Movement

Overall, quarter over quarter, 58% of customers tend to remain in their existing segments and 21% increase or decrease their loyalty to a merchant, showing that QSR customers tend to be more promiscuous than other industries. Also, there is much more extensive customer loyalty movement within the “not loyal” segments.

Segment Movement

While all segments show purchase behavior movement, the Tied segment (part of Not Loyal customers) shows the most movement - both up (26%) and down (45%) - into other segments.

QSR Leaky Bucket

QSR brands are acquiring new customers at a 3x faster clip than they are losing customers. Yet these customers are less loyal to any specific brand so nurturing the relationship is key.

Diving deeper into the individual segments tells us:

• Loyal customers and those that Prefer the competition are the most rigid (with 63% and 72% staying the same, respectively). Those customers that are Tied have the greatest propensity for a behavior change (with only 13% staying the same).
• ‍Loyal customers are far less likely to churn. Customers that are Tied are 50% more likely to churn and customers that Prefer the competition are 100% more likely to churn!

Definitions of Customer Segments

‍
Loyal Customers
Loyal: Only shop with a specific brand, or have the highest share of wallet with a given brand and relative rank is lower than all other brands in consideration set

Not Loyal Customers
Tied: Similar relative ranks to 2 or more brands regardless of share of wallet ranking
‍Prefer: Lower share of wallet and higher rank than other brands in their consideration set
‍Lapsed: Shopped historically but do not shop currently, as defined by the analysis time period
‍New: Shop currently but have not shopped historically, as defined by the analysis time period

Takeaways

Marketers know it’s more costly to acquire or re-acquire customers than to keep existing ones engaged. When QSRs neglect current customers, they risk losing them and undoing past investment - not loyal customers are 50%-100% more likely to lapse/churn than loyal customers. But also QSRs are doing a relatively good job of bringing in new customers so staying top of mind is even more important. Marketers must continuously nurture relationships, understand customer needs, and offer seamless experiences. To foster loyalty with your customers, consider these recommendations:

• Use an “always on” strategy to keep customers engaged, regardless of purchase frequency.
• Regularly update/refine customer segments and adjust reward offers to keep them engaged.
• Use targeted campaigns to boost loyalty and revenue.

Grocery Category Loyal Customers

On average, 75% of a merchant’s customers are not actually loyal. But the loyal segment (25%) has a much higher share of wallet (67%) than a not loyal segment (13%).

Top Customers (top 20% of most frequent transactors) still show that 25% are not loyal customers. Yet the loyal customer segment shows a 2x higher share of wallet.

Takeaways - Building Grocery Loyalty in the UK

Loyalty in the UK grocery sector is highly unstable. Only 25% of shoppers are truly loyal, yet they contribute 67% of their share of wallet (SOW) to a single merchant. Even within the top customers, 25% are still not totally loyal. Loyalty is fragile and demands ongoing effort as competition is always close by. To stay top of mind, marketers must continuously nurture relationships, understand customer needs, and offer seamless experiences. To foster loyalty with your customers, consider these recommendations:

• Implement an always-on engagement strategy to keep customers connected, regardless of purchase frequency. 
• Regularly update/refine customer segments and adjust reward offers to keep them engaged.
• Use targeted campaigns to boost loyalty and revenue.

In our Loyalty Movement Report, we dive into customer behavior in the Big Box category to better understand engagement over time by analyzing 8 brands with more than $400B in consumer spend behavior.*

Big Box Retailer Category Loyal Customers

On average, 76% of a merchant’s customers are not actually loyal. But the loyal segment has a much higher share of wallet (70%) than a not loyal segment (15%).

Top Customers (top 10% of most frequent transactors) are evenly split between loyal and not loyal customers. But the loyal customer segment shows an almost 3x higher share of wallet.

Findings

We looked into purchase data at 8 big box retailers in the US over the last 8 quarters (Q1-23 through Q4-24) on a quarter by quarter basis to see whether even the “most loyal” customers showed changes in their purchase behavior.

‍Big Box Loyalty Movement

Overall, quarter over quarter, almost 80% of customers tend to remain in their existing segments while 20% increase or decrease their loyalty to a merchant. Yet there is much more extensive customer loyalty movement within the “not loyal” segments. 

Segment Movement

While all segments show purchase behavior movement, the Tied segment (part of Not Loyal customers) shows the most movement - both up (29%)  and down (36%) - into other segments.

Executive Summary

• Advertisers have increasingly used MMMs to better analyze the performance of their marketing efforts across channels, but continue to face some challenges with data.
• Measurement of card-linked offer (CLO) programs have also historically posed a challenge to MMMs.
• Cardlytics is working with leading marketing measurement experts to develop best practices for integrating Cardlytics campaign data into media mix models, helping our advertisers more accurately measure incremental impact of Cardlytics campaigns and the rest of their marketing program.

‍Media Mix Models and card-linked offers

For brand advertisers to truly understand and analyze the performance of their marketing efforts, measurement plays an essential role. Since it is not enough to analyze the performance of a single channel in isolation, advertisers lean on Media Mix Modeling (MMM) solutions to better understand the full picture of their marketing efforts, which channels are impacting their overall spend, and how to determine future budget allocation. MMMs have been especially beneficial for marketing analysis and reporting, marketing budget optimization, scenario planning, and performance tracking – but advertisers continue to face challenges with data quality, invalid or incomplete data inputs, and accounting for broader shifts in market economics. 

Measuring the effectiveness of card-linked offer (CLO) programs, such as Cardlytics’ platform, have historically posed a challenge to MMMs. Because our platform shows digital ads within the walled environment of digital banking channels and measures performance through card-linked data from our banking partners, it has been difficult for advertisers to get an accurate view of CLO performance. 

‍Integrating Cardlytics data with MMMs 

To help our advertisers address these challenges with CLO measurement, we are excited to announce that Cardlytics will be working with leading MMMs, including Analytic Partners and Ipsos MMA. By integrating Cardlytics data into these models, we are able to help our advertisers, modelers and analysts better understand the unique value of our platform as part of the overall marketing mix. 

Through a tailored training program with each MMM, we are working together to ensure that:

• Cardlytics data is properly incorporated into their models 
• Modelers understand how Cardlytics and card-linked offers work, and how CLO campaigns are measured 
• Data is interpreted appropriately and modelers are equipped with best practices for potential enhancements to their models (e.g., elevating lower-funnel metrics such as clicks and redemptions, rather than just ad impressions) 

In addition to integrating into MMMs, Cardlytics continues to invest in our own Test vs. Control solution to demonstrate the incremental benefits of our platform.

‍Considerations for enhancing measurement 

It’s important for advertisers to keep the following considerations in mind when thinking about CLO measurement with MMMs:

• Pay-for-performance advertising means that model relationships seen in other digital channels may not exist. Some models are better for upper-funnel media channels, which may not be appropriate for measuring the effectiveness of CLO campaigns.
• Our adstock and ability to provide campaign-level detail are unique, and provide full funnel visibility for deterministic customers, from impression to engagement to purchase. 
• Supplementing with customer-level metrics (e.g., Cardlytics’ Test vs. Control analysis) can provide a more comprehensive picture of campaign effectiveness.
