About Dennis Monschauer
Founder of OnMaTe and active in online marketing for more than 20 years.
My main areas of expertise are SEO, SEA, online consulting, digital strategy and AI-supported marketing processes. I help companies become more visible online, generate more qualified enquiries and prioritize digital measures in a meaningful way.
Online marketing with a clear view
For me, online marketing does not mean implementing as many measures as possible at the same time. What matters is identifying the right levers: What creates visibility? What generates enquiries? What truly improves the website?
And where can AI systems such as ChatGPT, Claude, Gemini or Perplexity help make processes faster, clearer and more efficient?
My path in online marketing
Starting out in digital marketing
My professional journey in online marketing began in 2001 at the jobs.de group. I worked there as an online marketing consultant and gained early practical experience in digital business models, reach building and performance-oriented marketing.
Strategic responsibility at guenstig.de
From 2003 to 2005, I worked as Online Marketing Director at guenstig.de. In this role, I was responsible for the strategic direction of online marketing and led important measures for growth, visibility and digital reach.
Founding and developing OnMaTe
With OnMaTe, I founded an online marketing agency that supports companies in a personal, transparent and strategic way. The focus is on SEO, SEA, keyword consulting, content optimization, AI-supported processes and honest consulting.
What defines my work
More than 20 years of experience: I know online marketing from an operational, strategic and entrepreneurial perspective.
A holistic view: SEO, SEA, content, websites, conversion and AI need to be considered together – not as separate silos.
Data and experience: I combine analyses, numbers and tools with practical experience from many projects.
Clear prioritization: Not every measure makes sense. I help assess effort and impact realistically.
AI with common sense: ChatGPT, Claude, Gemini, Perplexity and other AI systems are powerful tools, but they are not a ready-made strategy.
Honest consulting: I clearly explain what makes sense, what can wait and which measures you can safely skip.
My work with AI and modern search
The way people search and make decisions is changing. Alongside Google, AI systems such as ChatGPT, Claude, Gemini, Perplexity and other answer engines are becoming increasingly important.
That is why I focus intensively on how content needs to be structured, optimized and presented clearly today – not only for classic search engines, but also for AI systems, large language models and modern search environments.
This includes LLM optimization, structured content, clear topic clusters, clean internal linking, helpful FAQ sections and AI-supported content processes.
The important point is: not every AI tool is equally suitable for every task. ChatGPT, Claude, Gemini and Perplexity each have different strengths – for example in research, structuring, text quality, analysis or idea development. What matters is using the right systems properly and checking the results carefully from a professional perspective.
My vision for OnMaTe
OnMaTe is not meant to be an agency that simply works through tasks. My goal is to support companies over the long term, provide honest consulting and use digital measures in a way that truly fits their business model.
I believe in online marketing that is understandable, transparent and effective. No unnecessary jargon, no empty promises and no measures that sound good but deliver little.
