Blended ROAS measures revenue against combined ad spend across multiple channels or the full paid-media mix.
| Field | Detail |
|---|---|
| In plain English | It shows how the system is performing when you stop looking at one platform at a time. |
| Formula | Total Revenue / Total Paid Media Spend |
| Why it matters | Blended ROAS is useful when platform-level attribution overstates individual channel performance and leadership needs a more realistic system-wide view. |
| Good benchmark context | Blended ROAS works best when marketers need to compare the total paid-media engine against overall revenue efficiency, especially in ecommerce and mature multi-channel programs. |
Where interpretation of Blended ROAS most often goes wrong.
| Common mistake |
|---|
| Using blended ROAS without explaining the attribution source behind revenue. |
| Treating blended ROAS as a substitute for diagnosing weak channels. |
| Comparing blended ROAS across brands with very different margin structures or retention behavior. |
The Benchmarketing 4-Band Method. The Benchmarketing 4-Band Method reads every marketing metric against four percentile bands — P25 (bottom quartile), median, P75 (top quartile), and elite (top ~10%) — for a specific industry and channel, instead of a single cross-industry average. Averages blend brand and non-brand campaigns, $500/month and $500,000/month accounts, and unrelated industries into a number almost nobody actually has.
Where the numbers come from. The figures on this page come from the Benchmarketing benchmark dataset — thousands of curated benchmark observations across channels, industries, and US metro areas. Every statistic traces to a named source: WordStream Google Ads Benchmarks (2024), Meta Business Insights (2024), HubSpot Email Marketing Report (2024), Unbounce Conversion Benchmark Report (2024), Databox Marketing Benchmark Report (2024), AdLiftr Snapchat Ads Cost Benchmarks (2026), Ad Badger Amazon Advertising Benchmarks (2026). Benchmarketing does not publish anonymous "studies show" figures.
The Benchmarketing position. Beating the cross-industry average is a vanity milestone, not a target. Compare your number to the P25–P75 band for your specific industry and channel; if you are above average but below your industry's P75, you are leaving performance on the table.
