Platform ROAS is not the same as business ROAS
Every ad platform attributes as much revenue to itself as the attribution model allows. Google Ads, Meta Ads, and LinkedIn all report on the conversions they want credit for — and none of them are working from the same model. When you take the blended ROAS figure from each platform and try to reconcile it against actual revenue, the numbers rarely agree. The figure that matters — what it costs to close a paying customer — is almost never in any platform report.
