Your Shopify Data Is Lying — Here’s What to Track

Most Shopify brands think they’re data-driven… until they compare Shopify vs GA4 vs ad platform numbers and realize nothing matches.

In this episode of Winning With Shopify, Nick sits down with Tom Armfelt (ex–TK Maxx eCommerce + analytics) to break down the hidden tracking issues, why “best practice” can slow you down, and the metrics that actually matter when you want profitable growth.

You’ll learn how enterprise teams (like TK Maxx) approached fast experimentation, why A/B tests often fail in the real world, and how to simplify your Shopify stack without losing performance — while focusing on powerful metrics like Revenue Per Visitor (RPV) and Profit Per User (PPU).

What you’ll learn in this episode:

Why your tracking can look “correct” but still be wrong (GA4 dashboards ≠ truth)

The biggest Shopify analytics mistakes (and how to fix funnel consistency)

Why RPV beats conversion rate as a growth KPI

How PPU changes your ad strategy (and reveals what’s truly profitable)

The real reason A/B testing often isn’t reliable

How app overload silently slows sites + muddies your data

Why buying your own product reveals UX problems instantly

Lessons from TK Maxx: product turnover, SEO constraints, and moving faster at scale
