ROAS across platforms: compare the context, not just the ratio

Advertising platforms can report ROAS differently. This guide explains how to compare definitions, windows and source data before drawing conclusions.

Document the revenue source

Before comparing ROAS, record whether revenue came from provider attribution, an analytics system or an internal source. Different inputs can produce different answers.

Record attribution settings

Attribution model and window affect reported conversions and revenue. Keep those settings visible rather than presenting platform ROAS as perfectly interchangeable.

Compute blended ROAS first, channel ROAS second

Blended ROAS = total attributed revenue / total ad spend. Use it as one portfolio-level view, then use channel ROAS for tactical analysis inside that context.

Adnova presents ROAS alongside the spend and conversion data returned for connected accounts, so teams can compare results using one interface while retaining provider context.
