- Redesign 2026, ongoing collaboration since 2023
From an invisible WordPress to a Google- and AI-indexed platform, with an interactive France map.
Context
Désenfumage installs and brings up to standard smoke-extraction systems and containment screens for SMEs and professionals in Marseille and across France. Highly technical work, recognised quality, but limited digital visibility despite an existing site.
Challenge
The WordPress site worked but received few visits and few inbound requests. Poorly compressed photos slowed loading. No trace in LLMs. Updates were tedious.
- Slow WordPress site (LCP above 4 s) due to unoptimised photos
- No mention in ChatGPT, Perplexity or Gemini
- Painful blog updates through a poorly designed theme
- No map visualisation of service areas
- No structured data, pages poorly qualified by Google
