Connecting Meta ads data to Shopify revenue means matching what you spent on Facebook and Instagram ads to the actual orders those ads generated in your store, using a shared identifier like UTM parameters, order timestamps, or a direct data pipeline, rather than trusting Meta's self-reported conversion numbers alone. The reason this matters: Meta's Ads Manager and Shopify's order data rarely agree, and the gap between them is usually where your real ROAS is hiding.

Most founders either trust Meta's dashboard blindly or give up and eyeball it. Neither gets you an accurate number. What works is connecting the two systems directly so spend and revenue sit side by side, attributed the same way, every time.
