Chapter 1: Foundations – Defining your strategy

A website without strategy is a rudderless ship. Before coding a single line or choosing a design, it’s crucial to define your objectives.

1. Define your site type

  • Showcase Site: To present your company, your services and your values. The aim is to generate qualified contacts.
  • E-commerce site: To sell your products online. Here, fluidity and security are the watchwords.
  • Blog / Online magazine: Create a community, share your expertise and attract traffic with a content strategy.
  • Customized platform: For complex projects with specific functionalities (social networks, marketplaces, etc.).

2. Understanding your audience

Who are your ideal customers? What are their needs and motivations? Creating “personas” will help you design a site that speaks directly to them and meets their expectations.

3. Technology choice: The right tool for the right job

  • WordPress: Flexible and powerful, it’s ideal for blogs and showcase sites, with a huge library of plugins. It’s the solution we recommend 90% of the time.
  • Shopify / Prestashop: The undisputed leaders in e-commerce, they offer robust solutions for selling online without worrying about the technical side.
  • Custom development: For a unique project with features not available elsewhere. More expensive, but offers total freedom.

Chapter 2: Design and Development

Once you’ve defined your strategy, it’s time to build your website.

1. The tree structure: Organizing information

Create a detailed plan of all your pages. This is the backbone of your site. A good tree structure makes it easy for your visitors to navigate, and helps Google understand the structure of your content.

2. Webdesign (UI/UX): More than just aesthetics

Good design doesn’t just make your site beautiful. It must be intuitive(UX – User Experience) and consistent(UI – User Interface) with your brand. We always design our sites with a “mobile-first” approach, so that the experience is perfect on all screens.

3. Development : Bringing the project to life

That’s where the code comes in. We make sure your site is :

  • High-performance: Fast and lightweight for optimal user experience and better SEO.
  • Secure: protection against vulnerabilities and attacks.
  • Referenced (SEO-friendly): Built with good SEO practices to be naturally visible to search engines.

Chapter 3: Content and launch

The site is ready, but it will be nothing without quality content and a good deployment strategy.

1. Create content that sells

Write copy that engages your visitors and prompts them to take action. Use professional photos and videos to highlight your offer. It’s content that sets you apart from the competition.

2. SEO optimization

Before launching, we optimize each page with :

  • Relevant keywords in title tags and meta descriptions.
  • A coherent internal mesh to link your pages together.
  • Images optimized for loading and referencing.

3. The big day: Going online

We manage the publication of your site and carry out the final technical checks (redirects, Google indexing, etc.) for a smooth launch.

Conclusion: The road to success

Creating a website is an investment. But by following a rigorous methodology, combining strategy, design and technical expertise, your site will become a real growth lever for your company.
