How do I track which ad platform is actually driving sales for my boutique?

When Shopify and Meta show different revenue numbers from the same ads, it's nearly impossible to make confident budget decisions. The root problem is that each platform uses its own attribution model, and they often disagree significantly about which platform deserves credit for a sale.

A practical low-tech fix is to create a unique percentage-off discount code for each ad platform you use — for example META10 for Meta ads, GOOGLE10 for Google ads, and TIKTOK10 for TikTok. Use the same discount amount so the offer is consistent, but the different codes give you a third, platform-independent way to count which channel is actually driving purchases inside your own Shopify system.

This won't capture every sale — not all customers use discount codes — but it gives you a reliable directional signal. Combined with treating Shopify's revenue number as your conservative floor and Meta's as your optimistic ceiling, you'll have a much clearer picture of where your ad budget is working hardest.
