DUODUO
Vertou, Pays de la Loire
Founded in 2011 in Vertou, Duoduo designs merchant sites. It incorporates accessibility into its user experience audits and interface design.
Based in Vertou since 2011, Duoduo operates as an agency specialising in interface design and conversion optimisation for e-commerce. Two partners lead all projects with partner teams.
Accessibility is not offered as a separate service. The agency integrates it directly into its heuristic usability audit, which examines affordance, visual hierarchy and WCAG criteria across user journeys.
The approach draws on audience measurement, benchmarking and user testing conducted in person or remotely. Design begins with functional diagrams before moving to visual mockups.
Its clients include Feu Vert, Gemo and Lemaire, as well as Bourjois, Treca and Alain Afflelou. Its work includes the Feu Vert public e-commerce site redesign and Lemaire's international shop on Shopify.
Accessibility services offered
Audit, Consulting and support, Inclusive design
Audit
Accessibility is examined as part of a heuristic UX audit of user journeys. This analysis verifies user experience best practices, usability, affordance and information hierarchy.
Consulting and support
The agency guides e-commerce site creation or redesign through a co-creation approach. Follow-up relies on user testing conducted before design and sits within continuous improvement.
Inclusive design
Graphic design unfolds in two stages: first wireframes defining zones, content and functional aspects, then visual refinement establishing information hierarchy, affordance and usability.
Quote from the provider website
“L'UX heuristique: On vérifie que les best practices UX sont respectées. On parle d'accessibilité, d'affordance, de hiérarchie de l'information, d'utilisabilité et de convention d'usage.”
