Web agency for SEO strategy

We analyze your website and develop a suitable SEO strategy based on the company goals and your marketing strategy.

Technical SEO

SEO starts with site architecture. As a web agency with SEO know-how, we structure websites in such a way that search engines such as Google, Bing or Yahoo! interpret them correctly. We create a search engine-optimized URL structure, ensure fast loading times and pay attention to the correct crawling and indexing of the content.

SEO compliant content

Topic relevance is crucial for SEO to rank first in search results. In order for content to be classified as relevant, it must be formulated in a certain way. Our web agency works with partners who know exactly what is important when creating search engine optimized content for a website.

More Flexibility and even More Impressive Experiences Thanks to a Headless CMS

Headless CMS and traditional CMS in comparison

With the traditional CMS (Content Management System), the front end is heavily integrated into the CMS. The focus is not only on the content, but also on the layout and the communication channel (often only designed for websites). This loses flexibility and possibilities in the user interface. Today, content is in demand in a wide variety of places and on a wide variety of devices (website, mobile app, smartwatch, etc.). Accordingly, flexibility is a must. This is where the headless CMS comes into play. With the headless CMS approach, the CMS (backend) and frontend (user interface) are decoupled from one another. With the headless approach, the CMS only takes care of the content and its structure. The front end is then exclusively responsible for the display. It doesn't matter whether it's a mobile app, a social media channel or a newsletter from a traditional website. With the headless CMS, the front end is optimized for the respective device and channel, which guarantees perfect digital experiences.

Because of the following advantages, our web agency relies on a headless CMS

  • Manage content in one place and publish in many places
  • Headless CMS are cloud ready
  • Generic interface (REST API or GraphQL)
  • Independent frontend for optimal experiences
  • CaaS (Content as a Service) for maximum flexibility in the frontend
