Problem → approach → measurable result → what AI changed.
Case Studies: CRO, SEO, Analytics and Digital Products
Ten case studies. Each with its calculation basis, its tools, and what AI changed — or didn't.
| Project | Conversion gain |
|---|---|
| Infirmière Reconversion | +150% |
| Institut Cassiopée | +120% |
| SITL | +66% |
| Institut Cassiopée — paid traffic | +65% |
SITL: completion rate 27% → 45% (+66%). Matera: 22% → 38% (+73%). Not all ten cases are quantifiable — one is anonymized, RankyDocky and the SEO & GEO audit have no public-facing usage KPI, and the A/B test analysis concluded not to ship.
