What is MER?
Marketing efficiency ratio — total revenue divided by total marketing spend across all channels. It is a holistic metric that avoids the attribution pitfalls of platform-reported ROAS. Brands measuring MER often see the impact of podcast-style ads more clearly because the trust they build contributes to conversions that platform attribution may not credit directly.
