Case study
IT transformation consulting · CIOs
BleuLemon
Replace a 29-page Webflow site with a 116-page bilingual site that a non-technical team can run on its own, without losing the brand or the rankings already earned, and prepare BleuLemon to be read by search engines and AI assistants alike.
The context
BleuLemon is an IT transformation consultancy based in Paris and Lyon, and an Atlassian partner since 2008. A team of more than 30 supports CIOs and IT departments from scoping to deployment, then through to adoption of the tools: IT management and governance, Atlassian, artificial intelligence, application support and maintenance, across manufacturing and defense, banking, finance and insurance, retail and distribution, and luxury.
The starting point: a 29-page Webflow site and a blog hosted by a third party, on a subdomain. The audit run before design began, in July 2026, measured what that setup was costing: 73% of organic traffic carried by a single article hosted off the domain, the two pages that structure the offer sitting at 179 and 172 words, structured data invalidated by a stray space, and zero citations of BleuLemon across 20 AI assistant answers (ChatGPT, Perplexity).
The brief
The brief fit in a single sentence: a site worthy of a firm that speaks to CIOs, so technically exemplary, and one the marketing team could edit without a developer. The expectations:
- Start from the dataAn audit of the existing site, its SEO and its visibility in AI assistants, a map of 359 keywords and a page-by-page read of 10 competitor sites, all before design began.
- Two languages, equal footingA complete English version, with translated URLs and reciprocal hreflang, not a machine translation laid over the French.
- Bring the blog home17 articles hosted off the domain, to be brought back onto the site in both languages, without breaking the URLs Google already knows.
- Lose nothing301 redirects from every old URL, those of the Webflow site as well as each article of the old blog, and continuity of audience tracking.
- A self-sufficient teamThree people at BleuLemon, none of them developers, must be able to change a text, a page or the menu, review it in staging and publish it themselves.
The design approach
BleuLemon's 2026 brand guidelines applied to the letter: deep blue, mint, coral, chartreuse, horizon blue, and Montserrat as the sole typeface. The stance, summed up by the sales leadership in a single phrase, "it's sharp, but it's soft": a clear site, with measured corner radii, where proof comes before effect.
Adoption as the promise
The homepage headline puts adoption at the center of the site, rather than the rollout of a tool: "The tool is an expense. You are the one who turns it into an investment."
Sections that carry the offer
IT management and governance, Atlassian, artificial intelligence, industries, training: each family of services has its own in-depth pages, where the old site covered its two sections in under 180 words.
Verifiable proof
Brands approved by the client, client cases presented by industry, the Atlassian partnership worded exactly as the official directory confirms it: every claim on the site holds up in front of a buyer who checks.
Motion in its place
Entrance animations reserved for headings and image cards, carefully crafted hover states, and everything stops when the visitor has set their device to reduced motion.
The build
- A 100% static site built with Astro and hosted on Cloudflare Pages: no CMS to maintain, no database, and each approved change is live in under a minute.
- One plain HTML fragment per page: the BleuLemon team describes the change it wants in French, an agent carries it out, staging is reviewed, and going live takes two steps.
- 116 pages in two languages, translated URLs, reciprocal hreflang, and a single Organization node shared by all the structured data: 679 JSON-LD blocks validated, 0 invalid.
- 51 redirects, all 301: the old Webflow URLs, the 17 articles of the old blog, and the blog.bleulemon.fr subdomain folded back into the site.
- Ready for AI: a robots.txt that explicitly allows GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot, llms.txt and llms-full.txt files regenerated from the pages, WebMCP annotations on the 4 forms, an IndexNow key.
- Media re-encoded: the homepage video from 19.9 MB to 688 KB, 14 photos from 25.4 MB to 1.8 MB in WebP, an 8.2 MB GIF replaced by a 588 KB MP4.
- Security headers and a content security policy, a consent banner that stores nothing until the visitor agrees, serverless forms.
- Handed over with the site: the visibility audit, the twelve-month acquisition plan and the 359-keyword map, so the team can steer what comes next on its own.
The project in numbers
- 116 pages live, 58 in French and 58 in English, versus 29 on the old site
- 17 blog articles brought back onto the domain and translated
- 359 keywords mapped, 10 competitor sites analyzed before design began
- 679 structured data blocks, 0 invalid
- 51 redirects in place, all 301, 18 of them for the old blog
- Homepage video weight cut by 96.5%
- 4 queries on the first page of Google inherited from the old blog, still in place five days after launch (measured on September 7, 2026)
