How often should I be looking at my cart abandonment data and making changes to my strategy?

As a Shopify store owner running ads in the fashion space, cart abandonment has been my silent revenue killer. Every month, I'm watching potentially thousands of dollars slip through the cracks. I've noticed customers will browse, add items to cart, and then... nothing. It's frustrating because I know these aren't just random browsers—these are people genuinely interested in my products. My Meta ads are driving quality traffic, but my conversion rates are stubbornly stuck around 2-3%. I've tried generic discount popups, but they feel spammy and don't seem to create genuine urgency. What I need is a systematic approach to understanding why people are leaving and a strategic way to re-engage them without devaluing my brand. I'm not just looking for a quick fix, but a data-driven method to continuously optimize my cart recovery strategy. The stakes are high—improving cart conversion by even 10% could dramatically improve my ROAS and make my ad spend significantly more efficient.
