A complete delivery

What is prepared before launch.

A lasting website needs more than a collection of screens. The message, mobile journeys, secure exchanges and content administration have to work together. Languages and market-specific content are agreed early so the structure supports your actual audience.

  • Content architectureNavigation and pages built around the questions your prospects ask.
  • Responsive designAn interface consistent with your identity and usable across screen sizes.
  • Search visibilityHeadings, metadata, internal links, structured data and content that search engines can access.
  • Performance & accessibilityAppropriate media, efficient loading and journeys usable with a keyboard.
  • Manageable CMSYour team can update the agreed pages, media and essential business information.
  • Production releaseTesting, backups, domain configuration, HTTPS, forms and final live checks.

A clear delivery method

Four steps from the initial idea to a live website.

The level of detail adapts to the project. Discovery establishes the purpose, reviews make decisions visible, and testing confirms that the agreed journeys work before publication.

  1. DiscoveryGoals, audiences, available content, functions and constraints.
  2. Structure & visual directionInformation architecture, priority messages, useful mock-ups and brand identity.
  3. DevelopmentCMS, components, responsive layouts, technical SEO and agreed integrations.
  4. Acceptance & launchTests, corrections, CMS introduction and a controlled release.

Delivered websites and the work behind them.

A developer in France, working with your team across borders

I work with European and international businesses through remote discovery sessions, design reviews and working demonstrations. We agree meeting times around your location and identify who supplies content, approves layouts and validates the final journeys. You keep direct contact with the person building the website throughout delivery.

Content follows your customers’ questions, services and actual markets. Language versions need their own messages, navigation and search context, not just a translated menu. These requirements, external integrations and hosting preferences are discussed before the quote, with regular reviews through testing and launch.

How much does a professional website cost?

The published business website offer starts at €1,500 excluding VAT for up to five pages, with supplied content, responsive design, CMS, a form, essential SEO, tests and launch. Catalogues, e-commerce and custom features need their own quote. Additional languages, hosting and external services are identified in the scope.

Can my team update the website?

Yes. The agreed content areas are manageable through the CMS. An introduction to administration is included in the business website scope shown on the pricing page.

Is SEO included?

The initial technical and on-page foundations are included: heading structure, metadata, URLs, sitemap, performance, responsive layouts and structured data. Ongoing editorial strategy, market research and reputation-building require a separate scope. Search rankings cannot be guaranteed.

Can you take over an existing website?

Yes, after reviewing content, technology, access, search visibility and the elements to preserve. The redesign page explains the approach and the checks needed before a migration.

Can we work together from another country?

Yes. I am based in France and work remotely with European and international teams. Meeting times, review stages and content responsibilities are agreed in advance. Quotes are in euros, with hosting, third-party services and ongoing maintenance distinguished from the initial build.
