We've been working with Blauwe Monsters for over two years now as our online store's advertising agency, and they continue to deliver consistent and measurable results. What I especially appreciate is that they never stand still: they continue to optimize, contribute ideas, and grow with our business. The communication is pleasant and transparent, they respond quickly, and clearly understand e-commerce and performance marketing. No empty promises, just a down-to-earth approach focused on what really works.

They're doing link building for us. The pages where they write blog posts have been down for weeks. We discovered this ourselves. We reported it, but they're doing nothing about it. A complete waste of money. Update 09.03.2026 The problem mentioned above has been resolved. We also had a discussion about continuing our collaboration. A follow-up update will follow later.

Our first few meters with Blauwe Monsters show a nice movement in our online performance. In addition to the optimization of our SEA campaigns, we are seeing a particularly nice uplift in our SEO rankings. The account team consists of down-to-earth, hands-on experts who provide achievable expectations and speak in – very pleasantly – understandable language ;-)
