What does an SEO agency do?
As an SEO agency, Semtrix grows organic reach in a way you can plan for, and turns search demand into real contacts, leads and customers. Not with short-lived tactics, but with a strategy built around your website, your market and your goals. Semtrix takes search engine optimization personally. You get named contacts who know your project, a specialist team behind them, and communication that leaves you in no doubt about what is being worked on and why. Alongside classic optimization sits GEO optimization, a discipline of its own for visibility inside AI systems. As part of the Eskimoz group, Semtrix combines hands-on support from Düsseldorf and Essen with the technology and reach of a European network. An SEO agency optimizes websites so that search engines such as Google and Bing find them more easily. That covers technical SEO, on-page optimization, content strategy, keyword research, internal linking, link building, the growth of digital authority and continuous monitoring. The aim is to cover relevant search demand in full, raise a website's visibility and bring more qualified users to the site. In practice, search engine optimization means adapting a website to the criteria a given search engine applies: technically, editorially and structurally. Every engagement at Semtrix starts with an analysis. Website, rankings, content and competitors are examined one by one and rated by impact. Out of that comes an SEO strategy built on your actual starting point, aimed not only at better positions but also at user journeys, trust and measurable results. Strong rankings on their own are not enough. What counts is whether visibility produces enquiries, purchases or other interactions worth having. How quickly this works depends on the project. For evidenz.de we have raised visibility by 147% and traffic by 1,400% since the project began in 2022. For steingarten.com, organic users are up 500% since 2023 and 855 keywords now sit in the top three. Both projects continue, because SEO is not a state you reach once. It is a position you hold.
In short
An SEO agency makes websites easier to find in search engines such as Google and Bing by connecting technology, content and authority. It analyzes the current state, prioritizes actions by impact and implements them continuously. The goal is not visibility for its own sake, but more qualified enquiries, leads and customers. Semtrix has worked as an SEO agency since 2015 from Düsseldorf and Essen, and extends classic search engine optimization with GEO, visibility inside AI answer engines.

Which SEO services does Semtrix offer?
As an experienced SEO agency, Semtrix covers every part of search engine optimization that matters, from technology through content and authority to continuous monitoring. These building blocks work together: technology creates the foundation, content delivers relevance, authority earns trust, and monitoring keeps the strategy on course.
Technical SEO
Crawling, indexing, site architecture, load times, Core Web Vitals, internal linking, mobile optimization and clean handling of JavaScript content. Content can only realize its potential once search engines read a website without errors. There is more on the technical SEO page.
Content SEO
Topic architectures, keyword and entity clusters, landing pages, guides and FAQ structures that cover search intent in full and convince readers and search engines alike. Our content creation page shows how we develop them.
Off-page and authority
Digital PR, link earning and high-quality mentions that strengthen topical authority and brand perception. Targeted link acquisition is handled by our link building agency.
On-page optimization
Heading structure, metadata, internal linking and editorial relevance for every single page, brought together in on-page optimization.
Local SEO
Regional visibility, a strong Google Maps presence and location pages for local search demand.
Conversion optimization

Award-winning search expertise with an international backbone
Semtrix is part of the Eskimoz group, headquartered in Paris. Its 250 consultants bring project experience in 10 languages and work from the group's own offices in five countries. The teams know what makes each market different and pair local support with international reach. In Germany, around 40 specialists look after client projects from Düsseldorf and Essen. In-house data scientists and development teams work closely with the search specialists. That is where the modules of the Eskimoz App come from: CrawlR for technical analysis, Monitoring for rankings and AI Overviews, Scribe for content, Notorious for backlink comparison against competitors, and LLM Ranking for visibility inside AI systems. What comes out of research and development feeds straight into the daily work on your project. How well that holds up under competitive conditions is a matter of record: at the European Search Awards 2026 in Porto, the group was named Best Large Integrated Search Agency, and the judges singled out its early move into GEO. How clients experience the collaboration is public too: 5.0 on ProvenExpert from 192 reviews, and 4.8 on Google. Our case studies give you a sense of the work, and the about us page tells you more about the team and how we operate.
Visibility is not an end in itself. We prioritize what brings enquiries, and we make every decision easy to follow.

SEO and GEO
GEO: AI visibility as a discipline of its own alongside SEO.
More and more people put their questions straight to AI systems such as ChatGPT, Perplexity, Gemini or the AI Overviews. These systems return one answer rather than ten blue links. That is why GEO, Generative Engine Optimization, also known as GAIO, is not a sub-category of SEO. It is a discipline in its own right, with its own rules, metrics and methods.
Where SEO targets rankings and clicks, GEO is about whether and how a brand is mentioned, cited and recommended inside AI-generated answers. Semtrix measures that AI visibility with LLM Ranking from the Eskimoz App and derives specific actions from it. The GEO optimization and GEO agency pages explain how this works in detail. At Semtrix, SEO and GEO run in parallel and carry equal weight.

Modules
What you get: the services and modules of SEO optimization.
01
Technical SEO
Before content can be found at all, the technical basics have to hold. We take care of crawling, indexing, clean site architecture, internal linking and Core Web Vitals. Mobile-first has long been standard, as has clean handling of JavaScript content. Log file analysis adds transparency about how search engine bots actually move through your site.
02
Content SEO
Strong content is the heart of any SEO strategy. We develop topic architectures and keyword or entity clusters that map search intent in full. Whether the right answer is a detailed guide, a clear FAQ or a strategic pillar page, we choose the format and a tone of voice that works for search engines and readers alike.
03
Authority and PR
Lasting rankings need reputation as well as good content. With digital PR, intelligent link earning and targeted mentions, we strengthen your brand's authority. That produces valuable backlinks and visibility in contexts that matter, a decisive lever for building a brand over time.
04
Conversions
Traffic is only half the job; what it turns into is the other half. So we optimize landing pages rigorously for user experience and trust. Micro-conversions such as newsletter sign-ups or contact requests count here as much as the A/B tests we use to keep improving performance. That is how visibility becomes measurable success. ---

Effort & cost
What shapes effort, cost and strategy in SEO?
The cost and scope of ongoing SEO work depend heavily on where you start, which is why Semtrix does not work with off-the-shelf packages. A serious strategy begins with an analysis and a realistic read on the potential. Only then does it make sense to decide which services are worth doing and how intensively. Blanket promises made without looking at the website and the competition are no basis for that. The main factors at a glance:
Size and type of website
A small local service website needs a different strategy from a large online shop or a company with several locations.
Technical condition
Technical problems, relaunches or legacy issues determine how much groundwork is needed.
Competitive intensity
Hard-fought markets and keywords demand more investment in content and authority.
Existing content
Whether content already exists or has to be built from scratch changes the content effort considerably.
Link profile and authority
A weak or compromised backlink profile needs deliberate, clean development.
Target regions and languages
A local, national or international focus changes both strategy and scope.
Your benefits
What you gain with Semtrix as your SEO agency.
