Can I see if visitors from my Instagram ads have a higher cart abandonment rate than visitors from Google search?

I've been running ads on both Instagram and Google, and I'm starting to suspect something's off with my conversion funnel. My Instagram campaigns look great in terms of engagement—tons of likes, comments, and click-throughs—but when I look at my Shopify backend, something feels... weird. My gut tells me that Instagram visitors are dropping out of the purchase journey more frequently than my Google search traffic. But here's the problem: I don't have a clear, visual way to track and compare these audience behaviors. I'm basically flying blind. I know my ad spend isn't cheap, and every abandoned cart feels like money literally walking away. I need a way to understand exactly what's happening with different traffic sources. Are Instagram visitors just window shopping? Are they less committed buyers? Or is there something about my product pages that's turning them off? Without concrete data, I'm just guessing—and guessing doesn't grow a business. I want granular insights that show me not just who's abandoning carts, but WHY they're abandoning them. I need to know if it's a traffic quality issue or a website experience problem.
