What sellers say
“I've been optimizing ads on different marketplaces for years. On OTTO it was still always a pain. The numbers sit in four different places, so you pull reports, piece them together in Excel and then touch every ad one by one. You end up optimizing roughly or not at all, and you pay too much for ads. With MargenOptimierer I see right away where money is being lost and I shift it. Same budget, more revenue, and it's actually profitable.”

By sellers, for sellers
Built by a seller who runs his own ads.
I'm Keanu. With my own company I sell on OTTO and other marketplaces and run the ads myself. Before that I spent a long time as an ads manager at an agency, running ads for other sellers.
MargenOptimierer is the tool I always wished I had. See what an item really earns and steer the ads accordingly, without spending half a day on it.
