Should I count guest checkouts differently from registered users in my abandonment metrics?

As an e-commerce store owner, I've been wrestling with understanding the nuanced behavior of different customer types. Guest checkouts have always felt like a bit of a black box for me. On one hand, they represent potential customers who are interested enough to almost complete a purchase. On the other hand, they're essentially anonymous, making it challenging to track their journey and understand why they might abandon their cart. I've noticed that my guest checkout abandonment rates seem higher than my registered user rates, but I'm not sure if that's a universal trend or specific to my store. The lack of historical data and the inability to send follow-up emails makes guest checkouts feel like a missed opportunity. Are these users truly less committed, or are there friction points in my checkout process that are specifically deterring them? I'm looking for a strategic approach to not just measure these differences, but to actually convert more of these transient shoppers into loyal, registered customers.
