What you need to know
What is ecommerce customer retention?
Customer retention is the store’s ability to keep customers buying over time after their first purchase. Measure it through repeat behavior in comparable customer cohorts.
Why does customer retention matter?
Retention matters because a second purchase can grow the customer relationship without starting the acquisition process again. It also reveals whether the product, delivery, and service were good enough for someone to return.
Customer acquisition vs retention: what’s the difference?
Acquisition brings in a new customer; retention earns later purchases from an existing customer. The costs, messages, and success measures are different.
What is repeat purchase rate?
Repeat purchase rate is the share of customers in a defined group who place more than one order during the measurement window.
How is repeat purchase rate calculated?
Divide customers who made at least two purchases by all eligible customers in the same cohort, then multiply by 100. State the cohort and time window.
What is a returning customer?
A returning customer is someone the store can reliably identify as having purchased before. Define how guest, account and cross-device orders are matched.
What is a good repeat purchase rate?
A good repeat purchase rate is one that improves against a reliable baseline for the same product type, customer cohort and time window. A refill product and a wedding gift should not be judged against the same target.
Why aren’t customers buying again?
Customers may not buy again because they had a poor first experience, do not need the product yet, cannot find a suitable next item or receive irrelevant follow-up. Check these causes by first product, delivery results and acquisition source before offering a discount.
How long should it take customers to purchase again?
The expected time for a second purchase depends on how the product is used and why it was bought. Measure the typical gap between first and second orders for comparable customers instead of setting one deadline for the whole store.
Which products naturally have higher repeat-purchase potential?
Consumables, refills, replacements and products with useful accessories usually create more natural reasons to return. Durable one-time purchases can still lead to another order when the store offers compatible parts, gifts, or related products.
A quick store check
Group customers by first-purchase month and check how many place another order. Compare products with naturally different replacement cycles.

Frequently asked questions
Can a new store measure retention with limited history?
Yes. Start with early repeat behavior and the normal buying cycle, label the result as preliminary and update it as cohorts mature.
Is every returning visitor a retained customer?
No. Retention should use a defined customer event, usually another completed purchase, rather than website visits alone.
