Digital Concept & Strategy: The Foundation of Your Success
This involves analysing your objectives, target audiences and competitive landscape, selecting the appropriate technologies, planning the information architecture, user journeys and data structures, as well as defining integrations and security requirements. This concept serves as the guiding principle for design, development and future enhancements – and prevents costly detours.
Before we begin with design or development, we carry out a thorough analysis. We understand your business model and identify your target audiences and their needs. This strategic approach enables us to develop websites that not only look good but also achieve measurable business objectives.
UI/UX Design: Driving conversions through a perfect user experience
A good user experience ensures that visitors can navigate your site intuitively, find relevant information and build trust. Elements such as clear CTAs, logical information hierarchies, appealing design and mobile optimisation reduce bounce rates and increase the likelihood of visitors getting in touch or making a purchase.
We draw on insights gained from over twelve years of conversion optimisation to help you achieve your goals. We rely on data-driven design decisions rather than subjective judgements of taste. Every element of your website serves a clear purpose: to turn visitors into customers.
Custom Coding: Tailor-made solutions instead of unnecessary clutter
Custom coding means that we develop functions and modules tailored precisely to your requirements – rather than relying on standard plugins, which often come with unnecessary bloat. This results in a streamlined, high-performance solution that is easier to maintain and can be customised as required.
We use modern programming languages and frameworks such as Laravel, Vue.js, Next.js or headless CMS approaches, depending on the project requirements. Our selection is always based on criteria such as scalability, performance, security and the developer community.
Shopify & WooCommerce: E-commerce that sells
Shopify is ideal if you want to get started quickly, have minimal technical complexity and a clear focus on sales. WooCommerce is ideal if you already use a WordPress site or want more flexibility in terms of design and features.
We analyse your products, processes and budget requirements to recommend the right platform, set up your online shop and optimise it on an ongoing basis. Our aim: to boost turnover through better conversion rates and optimised checkout processes.
WordPress Development: A framework rather than a website builder
We don’t view WordPress as a ‘building block’ system, but as a framework. Instead of using lots of plugins, we programme bespoke functions, use modern page builders sparingly and focus on clean, resource-efficient templating.
This ensures your site remains fast, secure and easy to maintain in the long term. We also provide a well-designed backend so you can manage your content with ease. WordPress sites built by CSW regularly achieve Google PageSpeed scores of 90+.
Technology stack: Always the best solution for your project
We work with the technologies that best suit your requirements:
- WordPress for flexible content projects
- Laravel for robust back-ends
- Vue.js and React/Next.js for modern front-ends
- PHP and MySQL for traditional web applications
- Headless CMS for maximum flexibility
Our expertise also covers Joomla, Drupal, Typo3 and various headless CMS platforms. We always base our selection on criteria such as scalability, performance, security and the developer community.

Mr Schwab has excellent expertise and, since he’s been advising me on SEO, we’ve seen a significant rise in our rankings for many keywords; in many areas, we’ve climbed into the top 10 in no time at all or moved up several places within the top ten.

Whilst searching online for a new partner to handle the (web) design for my companies, I came across CSW. I was impressed by their distinctive style and the high quality of their portfolio. The company was therefore commissioned to create a complete corporate identity, website and business stationery for a newly established limited company. The result can only be described as outstanding.
