Financial Metrics
RPM (Revenue Per Mille)
The total amount of revenue generated by a publisher or broadcaster for every 1,000 impressions they successfully serve.
What is RPM (Revenue Per Mille)?
RPM is the seller-side cousin of CPM. Where CPM is the price an advertiser pays, RPM is the revenue a publisher collects: after platform fees, ad-network commissions, unsold inventory drag, and any other deductions. The two metrics are related but not identical: a €20 CPM on a programmatic platform might net the publisher only €12 RPM after the SSP takes its cut.
RPM is the yield metric broadcasters and podcast publishers live and die by. Optimising RPM means filling more avails at higher effective rates without sacrificing fill-rate. A podcast with strong host-read baseline rates and a healthy programmatic fallback for unsold inventory typically delivers the best overall RPM. Stations that neglect remnant monetisation leak significant RPM compared to peers who actively manage it.
Why it matters
A critical yield metric for digital audio and OTT platforms, ensuring that the programmatic ads being inserted are actually generating sufficient profit margins.
