Introduction
In our previous report, Redefining Customer Loyalty, Cardlytics defined loyalty as a consumer’s preference for a merchant over 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 newest Loyalty Movement Report, we dive into customer behavior in the Grocery category to better understand engagement over time by analyzing the entire grocery category with more than $200B in consumer spend behavior.*
Grocery Category Loyal Customers
On average, 58% of a merchant’s customers are not actually loyal. But the loyal segment has a much higher share of wallet (84%) than a not loyal segment (18%).

Top Customers (top 20% of most frequent transactors) still show that more than ⅓ are not loyal customers. Yet the loyal customer segment shows an almost 3x higher share of wallet.
Findings
We looked into purchase data at all groceries 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.
Grocery Loyalty Movement
Overall, quarter over quarter, 60% of customers tend to remain in their existing segments while 40% 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 (33%) and down (37%) - into other segments.

Grocery Leaky Bucket
Grocery brands are acquiring new customers yet even more existing customers are moving into the lapsed tier. This cycle can be reversed by continuing to nurture existing customers.

Diving deeper into the individual segments tells us:
- Loyal customers and those that Prefer the competition are the most rigid (with 81% and 71% staying the same, respectively). Those customers that are Tied have the greatest propensity for a behavior change (with only 20% staying the same).
- Loyal customers are far less likely to churn. Customers that are Tied are 42% more likely to churn and customers that Prefer the competition are 185% 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 brands neglect current customers, they risk losing them and undoing past investment - not loyal customers are 42%-185% more likely to lapse/churn than loyal customers. 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:
- 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.

Big Box Retail: Stop Taking Customer Loyalty for Granted
Introduction
In our previous report, Redefining Customer Loyalty, Cardlytics defined loyalty as a consumer’s preference for a merchant over 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 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.
