Calls to action (CTAs) are important but they don't need to be perfect.
Start with something basic and then work to improve it as you go.
The simplest one is to just describe how your product helps your customer. For example:
Repeat Customer Insights helps you better understand your customer behavior so you can better market to them.
See? Simple can be effective.
Use cohorts to find out who the best customers are in your Shopify store
Repeat Customer Insights will automatically group your customers into cohorts based on when they first purchased. This will let you see how the date customers bought would impact their behavior.
