Customer loyalty, or as described previously customer trust, can be easily measured.
Does that customer buy again?
That's it.
Sure there's other things like: do they recommend you to their friends, have they posted a review, etc. At the end of the day, those don't matter as much as cold hard orders. If the customer is still getting out their wallet then they still trust your store (are loyal enough).
This excludes stores who lock-in orders. If the customer has complained and is still upset, they might not have had time to switch away yet. Those customers are not loyal but there shouldn't be that many of them.
This is why measuring things like Repeat Purchase Rate are so effective for customer retention. They are a direct measurement of customer loyalty.
Want to have your Repeat Purchase Rate calculated for you? It's included for all Repeat Customer Insights.
