About Sébastien

I help businesses be visible where their customers are really looking: on Google, but also in the answers of ChatGPT, Perplexity, and Gemini. Twenty years in website creation and optimization, over 250 projects supported — from startups to large corporations (Chanel, CGT, SVP, Artefact, Ildi).

Classic SEO is no longer enough. Your prospects are now asking AI directly. My job: to ensure your site stands out in both worlds, with a solid WordPress technical foundation and a content strategy designed to rank *and* be cited.

What I can help you with

- SEO + GEO Audit and prioritized action plan
- WordPress technical optimization (performance, indexability, structured data)
- Content strategy focused on research and generative engines
- Tracking Google rankings + AI visibility over time
- Custom development: plugins, API integrations, e-commerce
- GDPR compliance, Google Tag Manager, security

How I work

I always start with your business objective before discussing technical details. No ready-made solutions, no jargon. I work directly, supported by a team of freelancers when the project requires it.

    WordPress and SEO expert, I offer complete management of the clic-campus.fr website, combining webmastering, referencing, and hosting to ensure performance, visibility, and security.

    I handle technical and evolutionary maintenance: updates of the CMS and plugins, integration of new features, content management, and user experience optimization. I ensure the site remains fast, functional, and secure, with regular performance monitoring and bug resolution.

    On the SEO side, I perform a complete audit, optimize pages for strategic keywords, improve the structure, tags, URLs, and content. I implement best technical practices (speed, mobile-first, indexing) and precise KPI tracking to attract qualified traffic and increase conversions.

    For hosting, I guarantee a reliable, secure, and high-performance infrastructure: SSL certificate management, regular backups, protection against attacks, and speed optimization via caching and CDN.

    My approach combines technical, strategic, and performance aspects, with the goal of maximizing the visibility, security, and growth of the clic-campus.fr website while providing an optimal experience for visitors and learners.
