Blended ROAS
Total revenue from all sources divided by total paid media spend across all channels — not limited to a single platform.
Formula
Why it matters
Platform-reported ROAS is inflated because Meta and Google each take credit for the same conversion. Blended ROAS removes double-counting by using actual revenue against actual total spend — giving a more honest view of paid media efficiency.
How to improve Blended ROAS
Reduce spend on channels with low marginal contribution, allocate more to highest-blended-ROAS channels, improve landing page conversion rates across all channels simultaneously.
E-commerce: 3–6×. B2B SaaS: 2–4×. DTC with short sales cycle: 4–8×.

Why is blended ROAS lower than platform ROAS?
Platform ROAS (what Meta or Google reports) counts every conversion they can attribute to their ads — which often overlaps with other channels. Blended ROAS uses actual total revenue, which avoids double-counting. The gap between the two indicates how much attribution overlap exists.
