Platform ROAS

Platform ROAS is the revenue an ad platform attributes to its own ads divided by what you spent on that platform.

Definition

Platform ROAS is the revenue an ad platform attributes to its own ads divided by what you spent on that platform.

FormulaPlatform ROAS = attributed revenue / spend on that platform

Example with made-up numbers: Meta reports 6,000 in purchase value on 2,000 of spend. Platform ROAS = 3.0.

How to use it

It depends on the platform's attribution model and window, so two platforms can both report strong ROAS for the same sales. Never add platform ROAS values together to get a total.

Use it to compare ads and ad sets inside one platform, and use MER to judge the whole business.

Measurement

MER vs ROAS: which number an agency should report

Platform ROAS tells you how an ad platform scores itself. MER tells you how the business did. A client review needs both, clearly labelled.
