How can I learn from competitor checkout flows?

As a Shopify store owner, I'm constantly battling with conversion rate optimization, and I know my checkout process could be the make-or-break point for my business. Recently, I've been frustrated seeing other brands in my niche seemingly converting visitors more smoothly than I am. I want to understand what they're doing differently - are they using smarter design, more compelling trust signals, or innovative checkout techniques? I'm not looking to copy them exactly, but I want to learn and adapt best practices that could give my store a competitive edge. My current checkout flow feels clunky, and I suspect I'm losing potential customers at the final hurdle. I've tried analyzing a few competitor sites manually, but it's time-consuming and I'm not sure I'm extracting the most valuable insights. I need a systematic approach to benchmark and improve my checkout experience without getting overwhelmed or spending weeks on research.
