Advidera GmbH & Co. KG

Based on our experience, we’d unfortunately advise against working with ADVIDERA. We hired ADVIDERA to manage our performance marketing activities. Before we started, we were told that the agreement could be terminated on a monthly basis. That flexibility was a key factor in our decision. However, when we wanted to end the collaboration due to significant technical and economic issues, we were informed that a three-month notice period applies to the end of the month—and that we would still have to keep paying through the end of October, even though we were stopping the operational work. That alone would already be disappointing. Even more concerning for us, though, was the quality of the services delivered. As part of a later evaluation and an audit, we identified significant structural errors. This wasn’t about normal fluctuations in performance marketing or the fact that some campaigns run better at times than others. Rather, we got the impression that fundamental areas—budget allocation, campaign logic, feed optimization, and day-to-day operations—were not implemented properly. In particular, we found the following issues critical: - Budgets were not consistently prioritized based on performance. - Revenue-generating campaigns and categories were constrained by budget limits, even though—based on our view—significantly more potential existed there. - A substantial portion of the Shopping budget went into campaigns with economically unjustifiable performance. - In our analysis, 77% of the Shopping budget—specifically €40,530.70—was invested in campaigns that generated only 27% of Shopping revenue—specifically €35,730.28—resulting in a ROAS of just 0.88. - Relevant feed attributes, such as energy efficiency classes, were not properly set, even though they play an important role in our market. - CSS and ratings were, in our view, not integrated to the necessary standard. - In our evaluation, the RSA and DSA non-brand campaigns ran with a ROAS below 1. For us, this wasn’t just disappointing results—it caused clear financial damage. We had to quickly rebuild the service, have the campaigns checked externally, and invest substantial internal resources to reorganize everything properly. Most disappointing was how things were handled after our termination. Instead of addressing the issues properly and working toward a fair solution, the response essentially pointed to the alleged contract term. We were even offered the option to “switch” the remaining term to SEO or social media, even though, in our view, the real problem was the lack of service quality and the lost trust in the way the account was managed. We repeatedly tried to resolve the matter calmly and without escalation. Our proposal was a clean termination of the collaboration effective 30.06.2026, no further invoices, and full release of all accounts, assets, and data. Unfortunately, this was initially rejected. Our conclusion: If you’re an e-commerce company that relies on performance marketing, you should carefully review—before working with ADVIDERA—what notice periods actually apply, what services are concretely included, how transparently budget decisions are documented, and which control mechanisms are in place. In our view, the collaboration was disappointing from a technical, financial, and communication standpoint. Based on our experience, we would not hire ADVIDERA again.

Unfortunately no recommendation. An answer after more than 1 1/2 months and then totally out of context or not at all appropriate in terms of content. That makes you feel pretty lost. But thank you HR. Then it would be better not to reply at all, that way you would be less annoyed.
