Whenever there's a recession, slowdown, or any other kind of downturn a lot of advice shifts from customer acquisition to customer retention.
It makes sense as new customers cost much more to acquire and thus create less profit in the short-term. A store with a healthy returning customer rate will be able to survive downturns more effectively.
In light of that advice, I've added a new metrics to the downturn analysis in Repeat Customer Insights:

This metric will compare how many new customers you've acquired this year and compare them to the number of returning customers. By using the current year you can see more easily see the latest customer behavior.
As always, the full Returning Customer Rate can be filtered by period or acquisition source. This pulls that information out and puts it next to other analyses important during downturns.
