As part of Repeat Customer Insights I'll review the metrics for some Shopify stores and give them some advice.
One common piece of advice I give is to improve how new customers are treated and to try to get them to place a second purchase.
Kevin Hillstorm gives the same advice in an article
The place where you make the biggest difference is in converting a recent first-time buyer to a second purchase. This is where your Welcome Program pays off in spades.
Kevin writes a lot and gets deep into the data all the time so if that's something you'd enjoy, I'd definitely recommend digging through his advice.
Using Repeat Customer Insights it's easy to get a better look at this critical first-to-second-purchase behavior. That's a core part of the Customer Purchase Latency report, along with the timing of that behavior.
