Processus

Comment se passe une refonte, de l'audit à la mise en ligne

  1. 01 Audit UX et données Sessions, abandons de navigation, points de blocage du formulaire ou du panier : où et pourquoi les visiteurs partent sans agir.
  2. 02 Architecture et maquette Les pages qui manquent, celles qui se cannibalisent, et la refonte graphique site internet alignée sur votre identité, pas sur un thème du marché.
  3. 03 Sections modifiables Chaque page est faite de sections que vous éditez vous-même. Le système de landing pages B2B : cinq landings, six blocs FAQ JSON-LD, sept formulaires, à partir d'un seul système de landing pages modulaire.
  4. 04 Migration et redirections Chaque ancienne URL redirige vers la nouvelle. Del Cielo a la Tierra : un site WordPress bilingue de 37 pages, sans plugin de traduction.
  5. 05 Mise en ligne et passation Comptes, code et documentation vous appartiennent. Agence de refonte ou freelance ? La différence tient là : un seul opérateur fait les cinq étapes, et vous savez qui appeler.

  • We had the pleasure of working with Juan on a recent project through Upwork, and we couldn’t be happier with the results. From the beginning, he demonstrated a deep understanding of WordPress and Elementor, and his ability to follow a brief was exceptional. He took the time to understand the vision thoroughly, asked the right questions, and offered valuable suggestions that elevated the final results far beyond our expectations. His technical skill set is top-notch, he knows the ins and outs of both WordPress and Elementor, and he used them expertly to create a fast, responsive, and beautifully designed website. What really stood out was his attention to detail and communication. Every element we requested was implemented perfectly, and even when we asked for revisions, he handled them quickly and professionally. He delivered the project on time, within budget, and with a level of polish that speaks volumes about his professionalism and passion for quality work. If you’re looking for a talented, reliable, and knowledgeable web developer who can bring your ideas to life using WordPress and Elementor, we highly recommend Juan!

Questions

Questions fréquentes

Quatre réponses, chacune assez courte pour se lire debout.

Combien coûte une refonte de site internet ?

Une refonte de site internet chez JSV-88 se chiffre sur devis après audit, ou entre dans le forfait mensuel à partir de 2 500 EUR. Le prix dépend du nombre de pages, de la plateforme et des intégrations, jamais d'un pack fixé avant d'avoir vu le site.

Combien de temps dure une refonte ?

Le délai dépend du nombre de pages, des contenus et de la migration éventuelle ; il est écrit dans le devis, étape par étape, et vous validez chaque étape avant la suivante. Une boutique avec catalogue prend davantage qu'un site vitrine.

Faut-il changer de plateforme pour refaire son site ?

Pas toujours. Une refonte site internet sur mesure peut rester sur WordPress ou Shopify si la plateforme convient à l'activité. Le changement se décide à l'audit, sur des faits : coût mensuel, dépendance à un builder, besoins e-commerce.

Le référencement est-il perdu pendant une refonte ?

Non, si la refonte site internet SEO est prévue dès l'architecture : redirections une à une, mêmes titres sur les pages qui rankent, sitemap mis à jour le jour de la mise en ligne. Les positions se suivent dans la Search Console avant et après.
