Over attribution calculator: see what guessing is costing you
Google says it made the sale. So does Meta. So does the email tool. Add them up and they have sold more than you did. Put in your own figures and see the over attribution in them, the spend behind it, and the ROAS your platforms report next to your real one.
Modelled, not measured. Over-claim grows with the number of platforms: each one counts the same sale as its own, so four platforms claim around 2.5 sales for every real one, in line with a Trace sample customer (274 claimed against 110 counted). Wasted spend starts at 4% and rises with each extra platform and with the share of budget on display and paid social, the channels most often claimed and least often seen in a journey. Coverage follows your consent rate. The Free Attribution Audit uses your real figures.
Questions people ask before they start
No. It is modelled from the sliders. The Free Attribution Audit scans your public pages and shows how much of your revenue Trace can already see.
Each platform counts the same sale or lead as its own. Add them up and the total is always more than the sales you made.
A consent banner that asks clearly, the snippet on every page, and the checkout tag in place. Coverage lists the causes in order of effect. See how our consent banner asks

This over attribution calculator runs on your own figures: monthly revenue, ad spend and how many platforms claim credit. It shows the sales they claim between them, the ROAS they report next to your real one, and the spend sitting behind the gap. Run a free audit, or read how Coverage works.
