Our values
All our solutions have been developed and tested within the Zander Group — one of Germany's leading plumbing, heating and electrical wholesalers. We do not sell theory, we sell what works in real businesses.
We work heavily AI-supported: faster results at lower costs. Proprietary tools like the AI Visibility Tracker and ETIM Classifier. Automation with n8n and Claude for repetitive processes.
16 specialists in Barcelona plus a team in Herdecke (Germany). GDPR native, servers in Europe, 14+ languages. We understand European markets because we are part of them.
98% client retention. Some have chosen us for over 12 years. We get involved as if it were our own business because for us, it is.
Every decision based on real data. Real-time dashboards with Snowflake, Amplitude and GSC. Transparent reporting, measurable ROI, no vanity metrics.
Servers in Europe, compliant processes from day one. We never share data with third parties without consent. It is not an add-on, it is part of our German DNA.
Core competencies
We do not resell third-party tools. Every solution is born from a real problem.
We do not just optimize for Google. We optimize for ChatGPT, Gemini, Perplexity and Claude. With our own AI Visibility Tracker we monitor in real time how AI models mention your brand, your competitors and your industry in 11+ languages. We combine technical SEO, content strategy and GEO (Generative Engine Optimization) so your brand is visible in EVERY search engine — classic or AI-powered.
Automated product descriptions, end-to-end blogs with integrated keyword research, automatic weekly SEO audits, intelligent support ticket routing, AI narrative reports, personalized outreach at scale, ad creatives and much more. All built with n8n and Claude, integrated into our clients systems. The result: processes that used to take hours now take minutes.
Correct hreflang, language architecture, real market-specific localization with native speakers — not auto-translation. We manage SEO in 14+ languages for clients in 20+ countries. From Barcelona and Herdecke we understand Mediterranean and DACH markets from the inside. Each project manager speaks their market language and understands the cultural and search particularities of each region.
