SEO explained simply

What does an SEO agency do?

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.

1. On-page optimization

Everything directly on your website: keyword research, clear service pages, helpful content, headings, title and meta description, and sensible internal linking.

2. Off-page optimization

Trust from outside: mentions in trade media, industry directories, review platforms and the local press show Google that your company is relevant.

3. Technical SEO

Fast loading times, clean indexing, a working sitemap, structured data and a website that works perfectly on smartphones.

4. Local SEO

A well-maintained Google Business Profile, genuine reviews, consistent company data and dedicated landing pages for every location where you want to win customers.

5. GEO – optimization for AI search

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.

FAQ

Frequently asked questions about our SEO agency

Your question isn't listed? Call us (free within Germany): +49 800 0010313

How long does it take for SEO to work?

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.

How much does an SEO agency cost?

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.

How do you measure success?

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.

SEO or Google Ads – which is better?

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.

What is the difference between SEO and GEO?

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.

Why an SEO agency from Cologne and Leverkusen?

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.

Do you also offer SEO consulting and workshops?

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.

Do you only work with companies from Cologne?

No. We support companies throughout Germany, Austria and Switzerland. We offer personal meetings in Cologne, Leverkusen and the surrounding area, all others via video.

How do I recognize a reputable SEO agency?

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.

Which agency knows SEO for AI search systems?

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.

Do you also offer web design?

Yes. We build fast WordPress websites and online shops designed for search engines and leads from day one – including copy, hosting and maintenance.

What happens in the free analysis?

We review your website, your rankings and your visibility in AI answers and show you the most important measures for more leads – free of charge and without obligation.
