01
Website creation: Sedun's excellence at the service of your image
Your website is your digital ambassador. In Sion, where word-of-mouth is still powerful, your site must confirm your seriousness and professionalism from the very first second of loading.
Modern web design and a meticulous user experience (UX)
We create websites that are not just aesthetically pleasing, but truly functional. By working on ergonomics (UX design), we ensure that your customers find essential information effortlessly. Whether you're a law firm in the city center or a construction company in the industrial zone, we tailor the design to your target audience to maximize engagement.
Technical performance and mobile optimization
Speed is a ruthless selection criterion on the web. Our sites are developed to be ultra-fast, a key element for the user experience and your Google ranking. With mobile traffic predominating in the Valais, all our projects are responsive, guaranteeing perfect reading on smartphones, whether your customers are in the office or on the ski slopes.
Security, Swiss hosting and compliance with the DPA
For a company in the Valais, data protection is a matter of trust. We offer secure hosting solutions in Switzerland, and make sure your site complies with the Swiss Federal Data Protection Act (DPA). We integrate SSL certificates and robust security protocols to protect your business and your users.

SEO & Local SEO: become the leader in your sector in Valais
Search Engine Optimization (SEO) is the most durable lever for attracting qualified customers. In Sion, competition on Google is intensifying, and getting on the first page has become a major strategic challenge.
Local SEO: from Sion to Martigny and Sierre
For SMEs in the Valais, being found by local customers is vital. We optimize your presence on geolocalized queries such as "fiduciaire Sion", "garage Valais central" or "architecte sédunois". By effectively managing your Google Business Profile, we place you on the map, where the majority of local searches are made.
Content strategy and semantic authority
Google rewards relevance. We help you build a strong content strategy by writing pages and articles that answer your prospects' real questions. By demonstrating your expertise through quality texts, you improve your ranking and strengthen your credibility with your audience.
Netlinking and regional popularity
A site's authority depends on its popularity on the web. We work on acquiring links from quality Swiss and Valaisan sites. This netlinking work reinforces the trust signal sent to Google, propelling your site above your competitors in the search results.
03
SEA & digital advertising: generate immediate results
While SEO is a long-term strategy, SEA (Search Engine Advertising) offers instant visibility. It's the perfect tool for rapid traffic acquisition or the launch of a specific promotion.
Google Ads: rigorous, efficient budget management
We design and manage your Google Ads campaigns so that you're visible exactly when your future customers are looking for your services. By precisely targeting the Sion district or the whole of the Valais, we optimize your bids to obtain the best possible cost per lead. Every franc invested is tracked to ensure maximum ROI.
Advertising on social networks (Social Ads)
Social networks like Facebook, Instagram and LinkedIn are ideal for reaching Valaisans in their everyday lives. We create visual, impactful advertising campaigns that capture attention and generate interaction. Whether you want to target professionals or the general public, we segment your audiences precisely for optimum impact.

E-commerce: open up your Valais store to the world
Online sales represent an exceptional opportunity for growth for local merchants and producers. It frees them from opening hours and geographical limitations.
Smooth, robust e-commerce platforms
We develop custom online stores using solutions such as Shopify or WooCommerce. Our focus is on simplifying the purchasing process and ensuring transaction security. Your store must be a real sales engine, capable of transforming a visitor's interest into a firm order in just a few clicks.
Swiss payments (TWINT) and optimized logistics
For successful e-commerce in Switzerland, it's crucial to offer local payment methods. We natively integrate TWINT, as well as secure credit card payments. We can also help you integrate your logistics flows with Swiss Post to ensure fast, reliable delivery to your customers.
