If you are still allocating marketing capital based on what Meta Ads Manager or Google Analytics reports in isolation, you are flying blind with your profit margins.
The In-Platform Illusion
Ever since cross-app tracking restrictions reshaped digital advertising, ad platforms have increasingly relied on modeled and delayed conversions. Meta claims credit for the sale; Google Search claims credit for the same sale; your email tool claims credit too.
