How does Alpomi handle attribution post-iOS14?

We use your Shopify order data as the ground truth and reconcile it against platform-reported conversions. This gives you iOS-resilient attribution that doesn't rely on pixel data that iOS14 degraded.

Why does my Meta ROAS look so different from reconciled ROAS?

Meta's default 7-day click + 1-day view window claims any purchase within 7 days of a click — even if the customer would have bought anyway, or bought because of a different channel. On average, Meta over-reports by ~26%.

How often does attribution data refresh?

Data refreshes on a scheduled sync (typically hourly; near-real-time where connectors allow).

Marketing Domain

Your ROAS looks great. Your bank account disagrees. Here's the problem.

This is the most common trap for SME owners running their own ads. The ROAS number in Google Ads looks like 4.5x. Meta shows 3.8x. But after COGS, shipping, returns, and payment fees, you're barely breaking even. The platforms are showing you revenue metrics, not profit metrics — and every platform uses a different window to claim credit. One documented case: an eCommerce owner running at 4.5 ROAS discovered they were generating £1,200 profit on £22,000 revenue. ROAS was a lie.

What ROAS Attribution does

Every major ad platform is built to claim maximum credit for your conversions. Meta's 7-day click + 1-day view window, Google's data-driven model, and TikTok's broad attribution settings result in the same purchase being counted across two or three platforms simultaneously. ROAS Attribution applies consistent rules across channels and de-duplicates conversions so you can compare platform-reported ROAS to reconciled performance—not inflated platform numbers. Multi-touch attribution (first/last/linear/time-decay/position-based; Markov & Shapley when journey volume supports it). Requires Alpomi pixel and sufficient converted journeys.

Why teams look for a ROAS Attribution solution

The real operational pain that drives people to Alpomi

Platform ROAS measures revenue, not what you actually keep

Google and Meta both claim the same conversion — your real conversion count is half what they show

The 'learning phase' burns budget without giving you reliable data to act on

Blended ROAS (total revenue ÷ total spend) is a much better signal but hard to calculate manually

The impact

What changes when you close the loop on this feature

Stop wasting budget on overstated ROAS

Consistent attribution rules across channels

No more spreadsheet reconciliation between Google and Meta reports

ROAS that matches your actual revenue

Blended ROAS calculated from actual spend and actual sales — not platform estimates

ROAS that matches your Shopify P&L

De-duplicated, iOS-resilient attribution using your actual order data

Channel contribution you can defend

See exactly which platform drove each sale — not self-reported over-attribution

Profitable scaling decisions

The brands that scaled into BFCM profitably had verified attribution first — not platform estimates

The shift

Before Alpomi vs After Alpomi

From pain to clarity with ROAS Attribution

With Alpomi

Check Alpomi: reconciled blended ROAS of 2.1. See platform-reported vs reconciled side by side. Know exactly which channel is over-claiming. Make budget decisions on the number that matches your orders.

Before

Scale the campaign with the best-looking ROAS. Profit doesn't move. Wonder why.

For growing businesses

4.5 ROAS but barely breaking even — here's why

Platform ROAS counts revenue, not profit. And every platform over-reports because they use their own attribution window. ROAS Attribution gives you one consistent number that actually reflects what your ad spend is returning.

For DTC brands

Meta and Google are both claiming credit for the same sale

When a customer clicks a TikTok ad, then a Meta retargeting ad, then a Google Shopping ad before buying — all three platforms log a full conversion. Your combined attributed revenue can be 2–3x your actual Shopify revenue. Attribution fixes this.

How it works

Get started in three steps

Step 1

Connect your platforms and Shopify

Link Google Ads, Meta, TikTok, and your Shopify store. We pull spend, conversion, and order data from all sources.

Step 2

We apply a consistent attribution model

One lookback window and consistent attribution logic across platforms. Conversions are de-duplicated so each sale is counted once.

Step 3

See reconciled ROAS vs platform-reported ROAS

Side-by-side comparison shows you exactly how much each platform is over-claiming. Your decisions are based on reconciled performance, not self-reported platform numbers.
