What is ROAS on OTTO? Ad revenue per euro of ads
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
ROAS tells you how many euros of ad revenue one euro of ad spend brought in.
It's 1 divided by ACoS. You'll find it in the ad console in the ROAS column, with a × after the number. Unlike ACoS, it doesn't get a color.
Example: ROAS for the acacia chair
Say ads for the acacia chair cost 50 € in the period and bring in 595 € of ad revenue from 5 chairs at 119 € each. ROAS is then 11.90×.
So every euro of ad spend brought in 11.90 € of ad revenue, and ACoS is 8.4%.
What else matters for ROAS
Two ROAS figures in the console
For a targeting or a search term, OTTO only counts the revenue of the advertised item, so the column „ROAS (beworbener Artikel)“ (ROAS, advertised item) applies there.
Your ad target as ROAS
If you'd rather work with ROAS, switch your ad target to ROAS under Einstellungen (settings) in the Vorgaben (defaults) tab. You then enter a target ROAS, and tiles and sentences name ROAS. The columns of the ad console stay as they are.
