Frequently asked questions

What kinds of websites do you build?

At Vitalyn, we build every kind of website: professional business sites, e-commerce stores (Shopify, Prestashop, WooCommerce), corporate websites, custom platforms, blogs and editorial sites. Our experience spans a wide range of industries, including architecture, communications, publishing, training and many more, with over 300 projects delivered in 20 years.

How long does it take to build a website?

Timelines depend on how complex your project is: plan on about 4 to 6 weeks for a business website, 6 to 10 weeks for a standard e-commerce site, and 3 to 6 months for complex custom development. In our first conversation, we'll work out a detailed schedule together that fits your goals and constraints.

How much does a professional website cost?

The cost of a website depends on several factors: the type of site, the features you need, how much customization it takes and how much content there is. Our prices start at €3,000 for a professional business website and €6,000 for a standard e-commerce site, and vary with your specific needs. Once we've reviewed your project, we'll send you a detailed, transparent quote.

Will I be able to update my website myself once it's live?

Absolutely! All our websites come with intuitive admin interfaces (WordPress, Prestashop, Shopify) that make managing your content easy. We train you to use your site and stay available to help. For custom websites, we build admin interfaces tailored to your specific needs.

How do you handle SEO for my website?

SEO is built in from the design stage: an optimized technical structure, clean standards-compliant code, fast load times, responsive design and solid Core Web Vitals. We optimize meta tags, semantic structure, internal linking and content around your target keywords. We also give you recommendations to grow your visibility over the long term.

Do you offer hosting and maintenance?

Yes, we offer secure, high-performance hosting sized to your traffic and needs (shared or dedicated servers). Our maintenance plans include security updates, regular backups, performance monitoring and technical support. Our team is always on hand to fix any issue quickly.

Do you work with clients outside Paris, Besançon and Normandy?

Absolutely! We work with clients all over France (Besançon, Paris, Normandy, Marseille, Lyon, Bordeaux, Lille, Strasbourg and more) and internationally too. Our process is built for remote collaboration, with video meetings and effective collaborative tools.

How do you keep my website secure?

Security is a priority for us. We follow best practices: secure hosting with SSL certificates, regular CMS and plugin updates, protection against SQL injection and cross-site scripting, a web application firewall and automated backups.

Can I see examples of websites you've built in my industry?

Of course! Our portfolio includes over 100 projects across many industries. In our first conversation, we'll show you projects similar to yours or in your field. You can also read our client testimonials and, if you'd like, we can put you in touch with some of our clients so they can tell you about their experience with Vitalyn.

What about AI search?

Your website will be optimized for GEO (Generative Engine Optimization) so it shows up in ChatGPT, Perplexity and other AI search tools.
