MixedMetrics

BY METRIC // MULTI-CHANNEL ATTRIBUTION

Multi-channel marketing attribution without the headache

Multi-channel marketing attribution usually means a long, brittle implementation that breaks the moment a platform changes its API. MixedMetrics takes a lighter path. It blends spend and revenue across GA4, Google Ads, Meta Ads, TikTok Ads, and Search Console, then reconciles to real Shopify and Stripe revenue.

What's working
Where money leaks

Illustrative example figures · not a customer account · your own stack connects read-only

Instead of arguing over last-click versus first-click, you get a fair, blended picture of how channels contribute, with revenue by channel and blended ROAS side by side in the Blend Board. The AI layer shows what changed and where money is leaking. Connectors are read-only and data is aggregated and consented with no PII exposure.

The short answer

Multi-channel attribution assigns credit for a sale across the channels that touched it, rather than handing all of it to the last click. Traditional multi-touch models are brittle and break when a platform changes its API, so MixedMetrics uses attribution-lite: it blends spend and revenue across every channel and reconciles to real Shopify and Stripe totals, giving a fair contribution picture without a tagging marathon. You see revenue by channel and blended ROAS side by side, from $79 per month.

Connect, do not migrate

Read-only connectors to the tools you already run. No re-platforming, no pixel surgery, first dashboard the same day.

Attribution approaches, and where a blended view fits

Swipe to see the full table

Approach How it assigns credit The catch
Last-click All credit to the final touch before the sale. Ignores every channel that created the demand; over-credits branded search.
First-click All credit to the first touch. Over-credits discovery and ignores what closed the sale.
Multi-touch models Splits credit across touches by a rule or algorithm. Heavy to implement and fragile; breaks when a platform changes tracking.
Blended (attribution-lite) Reconciles total spend to total real revenue across channels. Shows contribution and efficiency, not a per-touch percentage; that is usually enough.

In depth

How much attribution do you actually need?

Which attribution model should you use?

The honest answer for most teams is that the choice matters less than the arithmetic that sits above it. Last-click over-credits branded search, first-click over-credits discovery, and every multi-touch rule splits credit by an assumption you cannot audit. Each model produces a confident, different answer from the same data.

What none of them can do is exceed the revenue your bank actually received, which is why a blended total belongs above whichever model you pick. Our rundown of the common marketing attribution models covers what each one flatters and where it breaks.

What attribution cannot prove

Attribution tells you which touchpoints preceded a sale. It cannot tell you which of those sales would have happened anyway, and that gap is where most overspending hides. A channel that looks efficient under any model can still be buying customers who were already going to buy.

The methods that do answer the incrementality question are holdout tests and geo experiments, and at larger spend, media mix modeling. Our guides to incrementality testing and attribution versus marketing mix modeling cover when each is worth the effort.

Where the blended view fits

Use per-channel attribution to manage campaigns and the blended numbers to decide how much budget each channel deserves. The two answer different questions, and problems start when a per-channel figure is used to make a budget-level call.

That blended layer is blended ROAS and blended CAC, reconciled to store and billing totals. Our explainer on blended ROAS versus platform ROAS shows why summed platform revenue usually overstates by 30 to 60 percent, and marketing attribution software covers the wider tool category.
