Getting views but no sales — would this diagnostic system actually help?

I'm exploring a concept for small digital product sellers who use organic content to drive traffic but struggle to understand why that traffic isn't turning into sales.

The idea is a simple diagnostic system that maps:

Impressions → Engagement → Outbound Clicks → Store Visits → Sales

Instead of just showing analytics, it would identify the biggest measurable drop-off in the funnel and suggest which area to investigate next.

For example, if content is successfully generating store visits but very few visitors purchase, it would flag Store → Purchase and suggest variables to test next.

This is only a concept right now — not a finished product.

Would something like this genuinely help you diagnose what to work on next, or would your existing analytics already be enough? What would you change?
