Your customers no longer search only on Google. They ask ChatGPT, read AI Overviews and compare reviews on Google Maps. As an SEO marketing agency, we make sure your company shows up in all three places.
Technical SEO, strong service pages and helpful content – so you rank on page 1 for the terms your customers search for.
Clear facts, a strong brand and mentions on trusted websites, so that ChatGPT, Gemini and Perplexity name you.
Google Business Profile, reviews and local landing pages – for calls and enquiries from your area.
As an SEO and online marketing agency from Cologne and Leverkusen, we pursue one goal across eight disciplines: more qualified leads for your business – bookable individually or combined from a single source.

As a Semrush Enterprise Partner and Google Partner Premier, we measure not only rankings but also how often ChatGPT, Gemini, Perplexity and Google AI Overviews recommend your company. So you can see in black and white what our work achieves.

After a free initial consultation and a first analysis, you receive an individual, non-binding quote.
An SEO agency makes sure your website appears high on Google for the terms your customers search for – and turns visitors into leads. Search engine optimization consists of five building blocks that work together.
Google Ads bring clicks immediately but cost money for each one. SEO builds lasting visibility that keeps working without an ad budget. Both are strongest together.
Everything directly on your website: keyword research, clear service pages, helpful content, headings, title and meta description, and sensible internal linking.
Trust from outside: mentions in trade media, industry directories, review platforms and the local press show Google that your company is relevant.
Fast loading times, clean indexing, a working sitemap, structured data and a website that works perfectly on smartphones.
A well-maintained Google Business Profile, genuine reviews, consistent company data and dedicated landing pages for every location where you want to win customers.
Generative Engine Optimization prepares content so that ChatGPT, Perplexity and Google AI Overviews cite your company as a source: clear answers, verifiable facts, a recognizable brand and mentions on comparison and expert websites.
With us there are no hold queues and no ticket system. SEO Marketing GmbH is an SEO and GEO agency based in Leverkusen, founded in 2018 and managed by Alexander Zimpel and Melanie Zimpel-Fantastico. Both support your project personally – from the first analysis to ongoing reporting.

First improvements usually appear after 6 to 12 weeks. Stable top rankings for competitive keywords usually take 4 to 9 months – depending on competition and starting point.
Costs depend on the competition and the number of your services and locations. We offer three models: a one-off SEO audit with strategy, ongoing SEO and GEO support, and enterprise projects. After the free initial consultation you receive an individual quote.
We measure rankings with Semrush Enterprise, clicks via Google Search Console, mentions in AI answers and, above all, your leads from forms, calls and appointments in Google Analytics 4.
Google Ads bring visitors immediately but cost money per click. SEO takes longer but then works for the long term. For most companies, the combination is the most cost-effective.
SEO targets rankings in Google Search, GEO targets mentions in AI answers such as ChatGPT or Google AI Overviews. Both build on the same foundations: good content, clean technology and a trustworthy brand.
A regional SEO agency knows the Cologne market, typical search terms and the districts where your customers live. For SEO in Cologne this means local landing pages, a well-maintained Google Business Profile and personal meetings on site instead of anonymous support.
Yes. In addition to ongoing SEO, we offer SEO consulting, audits and workshops for in-house teams – on site in Cologne and Leverkusen or online. You receive a clear action plan your team can implement itself.
No. We support companies throughout Germany, Austria and Switzerland. We offer personal meetings in Cologne, Leverkusen and the surrounding area, all others via video.
A reputable SEO agency doesn't promise a #1 guarantee, works transparently with clear reports, names real references and relies on sustainable measures instead of short-term tricks. Certifications such as Google Partner Premier and independent reviews are further indicators.
We optimize websites specifically for ChatGPT, Gemini, Perplexity and Google AI Overviews and measure the results with prompt tracking in Semrush Enterprise. So you can see how often AI systems mention and recommend your company.
Yes. We build fast WordPress websites and online shops designed for search engines and leads from day one – including copy, hosting and maintenance.
