How MargenOptimierer works
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.
MargenOptimierer shows you what you keep of your OTTO revenue per item and helps you align your OTTO advertising with your targets. Every night, MargenOptimierer fetches your numbers from OTTO and measures them against your targets, such as your target ACoS. You decide what to change based on that. A change only goes to OTTO after your click.
Du ordnest deine Artikel in Produktgruppen. Für jede Gruppe siehst du die Marge und legst Werbung an. Beides misst MargenOptimierer an deinen Zielen.
Example: The oak table from costs to bid
Say you've entered the purchase price and shipping costs for the oak table. In the period it made 1,700 € of revenue, 1,000 € of that after clicks on its ad. The Marge (margin) page subtracts all costs per sale from that, including the 340 € of ad spend. That leaves a 15% margin, exactly your target margin of 15%.
Its advertising is still above its target. 340 € of ad spend for 1,000 € of ad revenue is 34% ACoS, more than the 25% target ACoS of its garden furniture product group. 250 € would be allowed, so 90 € is over target.
In Optimierung (optimization), MargenOptimierer checks each targeting on its own, such as a keyword, not the whole item. The table is advertised through the keyword „gartentisch eiche“. It has 680 clicks and sits at 34% ACoS. A targeting is rated from 10 clicks, the default for minimum clicks. So the keyword is in the „Zu teuer“ (too expensive) row. You lower its bid by 20%, the default, and 0.50 € becomes 0.40 €.
MargenOptimierer then asks whether the new bid should go to OTTO right away. With Jetzt an OTTO senden (send to OTTO now), it goes to OTTO immediately. With Erst in den Changelog (to the Changelog first), it waits in the Changelog until you click Auswahl anwenden (apply selection) there. Which path leads to OTTO and when is explained in How do I send my changes to OTTO?
How far the numbers go
Numbers count up to yesterday
A day only counts once it's over. If your period runs until today, the numbers therefore end yesterday. There's more on this in How do I choose a period and compare it?
