Frequently asked questions

Find out more about web design/development, how we work & what a collaboration with CSW.AGENCY looks like.

A website is the digital home of your company. Poor architecture leads to long loading times, poor SEO ranking and frustrated users. With well thought-out web engineering, you create the basis for high performance, flexibility and a scalable future. You are investing in a stable foundation that can easily support new functions or marketing measures.

It includes the analysis of your goals, target groups and competitive environments, the selection of suitable technologies, the planning of information architecture, user journeys and data structures as well as the definition of integrations and security requirements. This concept forms the common thread for design, development and subsequent expansions - and prevents expensive detours.

Good user experience ensures that visitors navigate intuitively through your site, find relevant information and build trust. Elements such as clear CTAs, logical information hierarchies, appealing design and mobile optimization reduce bounces and increase the willingness to make contact or purchase. We use insights from over twelve years of conversion optimization to achieve your goals

Custom coding means that we develop functions and modules precisely for your requirements - instead of relying on standard plug-ins, which often come with unnecessary ballast. This results in a lean, high-performance solution that is easier to maintain and can be individually extended. We use modern languages and frameworks such as Laravel, Vue.js, Next.js or headless CMS approaches, depending on the project requirements

Shopify is suitable if you want to get started quickly, have little technical complexity and a clear focus on sales. WooCommerce is ideal if you are already using a WordPress site or want more flexibility in terms of design and functions. We analyze your products, processes and budget requirements to recommend the right platform, set up the store and continuously optimize it.

We don't see WordPress as a construction kit, but as a framework. Instead of using lots of plugins, we program tailor-made functions, use modern page builders sparingly and rely on clean, resource-saving templating. This keeps your site fast, secure and maintainable in the long term. We also provide a well thought-out backend so that you can easily maintain content.

With our CSW Lifeguard, we keep your website secure and performant at all times: daily backups, firewall protection, SSL configuration, malware scans, uptime monitoring and the installation of updates. You can reach our support team at any time via our ticket system; we respond quickly to faults or change requests.

The costs start at around €6,500 for smaller corporate sites and can rise to €50,000 and more depending on the scope, functions and integrations. Factors such as design complexity, number of templates, interfaces, multilingualism and individual features influence the price. We create transparent offers and show you which services bring which added value.

After the initial meeting, we analyze your goals and develop a concept. This is followed by the design phase with wireframes and mockups before we move on to development. In regular coordination rounds, we present progress, obtain feedback and adapt the project. After testing, optimization and training, the website goes live. After that, we continue to support you with maintenance and further development

We work with the technologies that best suit your requirements: WordPress for flexible content projects, Laravel for robust backends, Vue.js and React/Next.js for modern frontends, PHP and mySQL for classic web applications . Our expertise also covers Joomla, Drupal, Typo3 and headless CMS. The selection is always based on criteria such as scalability, performance, security and developer community.

Yes, we provide high-performance, GDPR-compliant hosting environments with our partner sweo.io and provide security updates and technical support. Our monitoring continuously checks performance and our support is available for questions and adjustments.

That depends on the scope: Simple one-pagers can be implemented within four weeks, medium-sized corporate sites usually take two to three months. For individual web apps with complex features, we allow several months. Together, we create a realistic schedule with intermediate steps and clear deadlines.

We rely on modern, widely used technologies, modular architectures and clean code. Regular updates, maintenance and performance optimizations keep your site technically up-to-date. Thanks to open standards and documentation, the website remains expandable and flexible for years to come.

WEB DESIGN & WEB DEVELOPMENT AT CSW

Your path to a future-proof web presence

Project inquiry & initial meeting
The first step is a non-binding initial meeting in which we get to know you and your company and discuss your goals and opportunities.
Preliminary analysis of target groups & market
In a preliminary analysis, we find out what makes your target market and, above all, your target group tick and how your competitors react to it.
Kickoff date
At the kick-off meeting, we fill out the project questionnaire together, define the project requirements and draw up a precise project plan. This ensures that everyone involved clearly understands the objectives and the course of the project and lays the foundation for successful collaboration.
Conception & Fulfillment
In the conception and fulfillment phase, we develop the UI/UX concept, create the sitemap and data structure and technically implement both the frontend and the backend. We also take care of the SEO and GEO setup and integrate the required content to create an optimal digital foundation for your project.
Deployment & GoLive
Before the GoLive, we carry out a final quality check, index the website via Google Webmaster Tools and carry out a comprehensive on-page analysis as well as the 301 redirect concept. Your project will only officially go live and be accessible to visitors once it has been successfully checked and indexed.
