Bernard Zitzer
SEO Consultant & Founder of doener.io
Berlin, Germany
I run bernard.digital, an SEO consultancy, and I built doener.io in 2026. The idea came after a long cold Berlin winter and roughly fifty disappointing döner visits: the rating systems we have tell you nothing about whether the food is any good. So I'm building one that does.
What I do
My day job is SEO consulting. My company bernard.digital advises companies that want serious, durable organic visibility — not the short-lived kind that gets swept away at the next Google update. I focus on technical SEO, content strategy, and programmatic-SEO architectures.
doener.io is my own project and at the same time the field lab for much of what I recommend to clients: structured data, local search, verified user signals instead of scaled content. If you find the architecture behind the platform interesting — or want to build something similar — reach out via the contact form.
Focus areas
Why doener.io?
I'm not a restaurateur. I'm not a journalist. I'm someone who lives in Berlin, understands SEO professionally — and who at some point asked himself why the rating systems we all use are actually so bad at finding good food.
Google shows star averages. Those measure everything — service, parking, ambience — and average the food down. The same place gets three-point deductions for bad service when really the döner had earned them. Conversely, bad food gets compensated by friendly waiters. The result: the best döner in any city never ranks in the top three.
doener.io asks different things. How's the bread toasted? Veal or chicken? Sauce house-made? Structured, per-product criteria, photo verification, no service dilution. As a side-effect it becomes my public lab for programmatic SEO under real competitive conditions.
