Your combined attributed revenue is 3x your actual Shopify revenue. This is why.
Post-iOS14, every major platform shifted to broader attribution windows and modelled conversions. Meta defaults to 7-day click + 1-day view. Google uses data-driven attribution with a 30-day window. TikTok runs on 7-day click + 1-day view. A customer who sees a TikTok ad, clicks a Meta retargeting ad, and then converts via Google Search is counted as a full conversion on all three platforms. One DTC brand with 600 actual orders documented 1,050+ attributed conversions across platforms. The ROAS you're optimising from is fiction.
Why For e-commerce look for this solution
The real operational pain we solve
Problem
A single Shopify order can be claimed by Meta, Google, and TikTok simultaneously
Problem
Meta over-reports conversions by 26% on average — much more for some brands
Problem
iOS14 removed 30–50% of attributable conversion data from Facebook's pixel
Problem
Scaling decisions made on inflated platform ROAS consistently disappoint when you check Shopify
How ROAS Attribution helps
ROAS Attribution deduplicates conversions across platforms and reconciles ad data with your actual Shopify orders. The number you see is the ROAS you actually achieved — not the sum of what every platform claims. For DTC brands, this is the difference between scaling a profitable channel and pouring budget into one that only looks profitable.
Before Alpomi vs After Alpomi
From pain to clarity with ROAS Attribution
