Tony Chopp, walks through the Hierarchy of Metrics — the framework our Prophit Engineers use to diagnose problems and take action for 170+ ecommerce brands.

In this episode, Tony and Richard break down a real brand example in Statlas, showing how you go from a contribution margin miss all the way down to a specific campaign adjustment in Google Ads.

The hierarchy:

• Business-level metrics (revenue, contribution margin, ad spend)

• Customer-level metrics (new vs. returning, paid vs. organic)

• Channel-level metrics (Google, Meta, email — iROAS by channel)

• Campaign-level actions (bids, budgets, new creative)

Key takeaways:

• Your ROAS target should be backed into through incrementality math and unit economics — not vibes

• “4 is not necessarily better than 3” — if 3 is the right number based on your COGS and incrementality, targeting 4 leaves volume on the table

• Over-efficiency is a symptom of underspend, not a badge of honor

• Good data in = good decisions out. The system is only as strong as your cost data, audience segmentation, and incrementality testing
