About Martin Kaltwasser.
I help companies become visible in Google and in AI answers and turn that into customers. To do this, I combine SEO, GEO, content and the question of what convinces visitors.

Making an impact.
Why work with me
For 15 years, I have combined courage in decisions with discipline in execution. I know both sides of the table and hate burning your money as much as my own. Marketing that counts.
How we work together
You know where you stand, what is holding you back and what comes next. I analyze, set priorities and support the implementation with your team. I also tell you which measures you can save yourself.
Digital visibility is not created in isolation in the SEO team. It emerges where content, technology, brand, and product interact meaningfully.
What clients say.
