Which traffic sources have the highest cart abandonment?

As a Shopify store owner in the fashion space, cart abandonment has been driving me crazy. I'm spending significant money on ads across multiple channels - Meta, Google, TikTok, email campaigns - but my conversion rates are frustratingly inconsistent. Some days, it feels like I'm pouring marketing dollars into a leaky bucket. I've noticed different traffic sources seem to behave totally differently: my Instagram traffic looks promising with high engagement, but the actual checkout completion rate is shockingly low. Google Shopping ads drive more qualified traffic, but they're also dropping off at an alarming rate. I've tried generic pop-ups and discount codes, but nothing seems to create genuine urgency. My team keeps asking about our funnel metrics, and honestly, I'm tired of not having a clear, data-driven strategy to understand and reduce cart abandonment. I need a solution that doesn't just track the problem but actively helps convert those wavering customers. The financial impact is real - even a 2-3% improvement in conversion could dramatically change our monthly revenue. I'm looking for a systematic approach that can analyze traffic sources, predict purchase intent, and dynamically offer the right incentive to the right visitor at the right moment.
