Between competition and white space.
We combine classic SEO with GEO into a strategy that secures strong brands in the long term. Because anyone who wants to be found today needs top rankings on Google and presence in AI answers.
Red Ocean · Classic SEO
Become visible where many people search.
Classic SEO targets keywords with high search volume – where competition is greatest, on Google. This allows us to measure exactly how many people are interested in which topics, and plan website content and online communication accordingly. With strong, user-centred content, cleanly structured code and fast loading times, we ensure companies achieve top rankings in the long term.
Blue Ocean · GEO
Become visible where AI answers.
Generative Engine Optimization (GEO) positions companies in ChatGPT, Gemini, Perplexity, Claude and Copilot. Search volumes for individual prompts are barely measurable yet, and competition is accordingly still relatively low. At the same time, two-thirds of Germans already use generative AI. For this, website content and digital reputation must be developed so that AI systems understand them, judge them as recommendable and recommend them.
Process
For this strategy to work, it's not enough to simply produce content. What matters is identifying the right topics, prioritising them cleanly and implementing them in a structured way.
Analysis
It all starts with clarity. We analyse positioning, competition and the needs of the target audience. We also assess existing content, technical SEO and GEO, identifying initial Red and Blue Ocean potential.
Concept
Based on the analysis, we develop a clear SEO and GEO strategy: which topics, keywords and prompts are really relevant? Where does differentiation arise? We then define the concrete measures for on-page optimisation and off-page communication.
For many SMEs, this consulting is eligible for funding – up to 50% funding possible.

On-page and off-page optimisation can be carried out in-house or by us. We're happy to help implement and optimise AI processes, take care of monitoring and quality assurance, and provide continuous optimisation impulses.

Severin Lucks
Founder & SEO Consultant, DELUCKS
For 25 years I have been exploring what visibility online really means – and for 20 years I have advised companies on how to achieve it.
As an SEO trainer at the eMBIS Akademie and SEO expert for the bestseller Think Content I combine theory and practice.
What drives me: thinking of strategies, content, code and conversions as one system – and achieving results that can be measured.
No obligation. Clear. No sales pitch.
Client voices
You can feel in every minute that Severin is passionate about the topic. His video course guides you clearly, in a structured way and without detours through GEO/LLMO - everything explained precisely and to the point. A top-notch training for anyone who wants to get up to speed quickly on this subject.
Mathias Leier
Selbständig
Severin delivered cutting-edge information at this GEO training too. Every time, new tools are introduced that make daily SEO processes more efficient and, above all, automated. Severin isn't a theorist - he's a practitioner. For every topic he presents either the latest studies or his own case studies, backing up the impact in practice. He also always takes us a step into the future, showing how far the GEO topic has progressed in other countries (particularly the US) and what that means for us in the medium term. This lets you act now to be well prepared for the future of Google SEO and the requirements of LLMs.
Bernhard Mott
BachelorPrint
Severin's GEO course was a direct hit: it was always hands-on and offered a great look beyond our own horizon. Especially for us as a B2B company relying on content marketing and thought leadership with purely organic SEO, this is exactly what we need to find the right path in the age of AI search/SGE. On top of that, plenty of smart tips that make everyday work easier. In short: a great trainer who's passionate about the topic, inspiring, practice-oriented content, immediately applicable. Thank you, Severin - happy to do it again!

MD ELEKTRONIK
Working with Severin Lucks is simply outstanding. Although I initially wondered whether, as a sole trader, I could and wanted to afford such premium support for my website, it became clear straight away that in a single hour I receive many times the value I had experienced before. Severin Lucks thinks fast and ahead, makes excellent suggestions and, thanks to his outstanding expertise and infrastructure (such as his own WordPress theme), implements everything with great ease. Despite a full diary he has the ability to give clear commitments on what will be delivered by when – and he always keeps them. If short-notice questions come up in between, he answers them immediately. The effect of reworking my website with him speaks for itself: I have finally achieved the rankings I wanted, and I have unshakeable confidence that my website will keep building on this strong positioning in the years ahead with his support.

I was lucky enough to have Severin Lucks recommended to me. That's how our collaboration on the revision of the book "Think Content!" came about, where he supported us with his SEO expertise. This allowed us to bring the SEO topics fully up to date. He didn't just look at the "pure" SEO chapters, but pointed out SEO-relevant aspects throughout the entire book. Above all, I'm grateful that he always responded quickly and reliably. That's essential on such a mammoth project to avoid any delays.
Irene Michl
The SEO training gave me deep insight into the responsibilities of an SEO manager, which ultimately led to me taking on the SEO manager role at DECATHLON.
Max Lamprecht
DECATHLON
Thanks to his many years of experience and extensive knowledge of SEO and far beyond, Severin supported and advised us on a wide range of topics during an in-house workshop, in an entertaining way. Thank you, Severin - we look forward to continuing to work together!
Bianca Geiselhart
Kittelberger media solutions
We booked a two-day in-house SEO seminar with DELUCKS for our positioning agency claudiusbähr+friends. Severin introduced us to a topic that was still completely new territory for many of us, in a humorous and very easy-to-understand way. SEO doesn't have to be dry and boring, and we're now really looking forward to putting it into practice! Thanks for the input, Severin!
Sabrina Friedrich
CB Friends
The seminar led by Severin Lucks as trainer was exactly that: intensive. Lucks is a walking SEO encyclopaedia, and information just keeps flowing out of him non-stop. That's challenging for the listener, but also highly effective and enlightening.
Jens Findeisen
SIEMENS
Severin Lucks is a highly valued eMBIS trainer colleague with whom I've also had the pleasure of working on client projects. Our collaboration has always been very friendly, and his SEO input is always delivered promptly and at the expected quality. I look forward to further joint projects in the future.
Miriam Löffler
Thanks for the professional and fast SEO help. You were able to help me where others got stuck!
Simone Glitsch
More than convinced: within a month of Phönix-Bad's relaunch, we more than doubled our visibility! The SEO plugin is a joy to work with - perfectly suited for beginners and professionals alike. Visually, in terms of content, and in every other way, it's top, top, top. And you won't find better support and assistance anywhere else than from DELUCKS. That deserves a sixth star.
Stephanie Laufs

Excellent advice, competent service and solid SEO knowledge - that's what sets the DELUCKS team apart. With this all-round worry-free package, you're always on the safe side. Thank you and keep it up!

Severin supported us quickly and reliably with the development and direction of our homepage, so we'd hire him again any time! Working together was always extremely pleasant and motivating.

Mr Lucks and his team do an outstanding job. Whatever the problem, help is provided immediately. Individual requests are never a problem either.
Carsten Böttcher
ELOORAC
Before meeting Severin, I was already convinced of the quality of my texts, but equally puzzled as to why relatively few people were interested in them. I'm increasingly enjoying the fact that I no longer see SEO as some kind of magic that I hand off to someone else, but that I'm learning that with a bit of my own time and lower costs, I can pull a powerful lever that doubled the number of users over the past year! Thanks, Severin.
Markus Breitenberger
We're always happy to draw on Severin Lucks' combined expertise whenever our SEO projects hit a snag or various adjustments are needed. We're very grateful for DELUCKS' support - a personable contact, broad expertise, and always the right solutions for every little issue, just in time. THANK YOU!

The SEO consulting was proactive and very insightful. Mr Lucks' expertise is impressive. He pointed out things we weren't even aware of, even though we already had many optimisation systems in place.
