A website redesign rebuilds all or part of an existing website: its design, structure, content and technical code. Unlike a cosmetic refresh, it rethinks the site structure, improves user journeys and modernises the technology.
Google reported in 2025 that 53% of mobile visitors leave pages taking more than three seconds to load. Where usability, speed or SEO problems have accumulated, a redesign becomes an investment rather than an expense: the new website converts better, ranks better and supports growth.

Redesigns differ widely. Identifying the appropriate scope before starting prevents over-investment and ensures the real problems are addressed.
| Redesign type | What changes | Indicative budget | Best for |
|---|---|---|---|
| Visual redesign | Design, visual identity and layout; no code or structural change | €1,500–€5,000 | A functional but dated-looking website |
| Structural redesign | Structure, UX, journeys and CMS; design retained or lightly updated | €4,000–€15,000 | Conversion or usability problems |
| Complete redesign | Design, structure, technology, SEO migration and content | €8,000–€80,000 | An obsolete website, CMS migration or new offer |
A website more than three years old can accumulate invisible technical debt. Semrush reported in 2025 that non-responsive websites lose 68% of mobile traffic on average. Watch for these warnings before performance decline becomes irreversible.
A structured redesign avoids 60% of budget overruns (Standish Group, 2024). Each stage follows the last; skipping the audit to begin with design is the leading cause of failure. This process has been used across more than 50 SME projects.
Étape 1
Review Core Web Vitals and speed, SEO rankings, organic traffic and links, and UX journeys and conversion. Use Analytics and Search Console; an in-depth audit takes one to two weeks.
Étape 2
Set traffic and conversion goals, scope, budget and schedule. Include personas, priority journeys and technical constraints; without this document, repeated changes can double costs.
Étape 3
Use audit data to restructure around strong pages, promising keywords and conversion journeys. Give each page one search intent, remove zombie pages with fewer than ten monthly visits and strengthen pillars.
Étape 4
Build wireframes and high-fidelity designs mobile-first. Test with five real users, which identifies 85% of usability problems (Nielsen Norman Group, 2024). User experience directly affects conversion.
Étape 5
Choose WordPress, Webflow or custom development to suit the need. Prioritise LCP below 2.5 seconds, WCAG 2.1 AA accessibility and HTTPS security, using staging for safe tests.
Étape 6
Map every existing URL to a new destination. Submit the sitemap to Search Console at launch. The SEO migration is the stage 80% of agencies mishandle.
Étape 7
Check every page on mobile and desktop, forms, internal links and speed. Monitor Core Web Vitals, traffic and rankings for 90 days and fix Search Console 404s immediately.

Prices range from €2,000 to €80,000 by website type, technical complexity and supplier. A 2024 Bpifrance study placed the average French SME brochure-site redesign at €8,500. An e-commerce website costs two to five times more.
| Website type | Price range | Typical time | Complexity |
|---|---|---|---|
| Brochure site (5–10 pages) | €2,000–€8,000 | 4–8 weeks | Low |
| Advanced brochure site (15–30 pages) | €8,000–€20,000 | 8–12 weeks | Medium |
| E-commerce (<500 products) | €10,000–€35,000 | 10–16 weeks | High |
| E-commerce (>500 products) | €25,000–€80,000 | 16–24 weeks | Very high |
| Web application/custom build | €20,000–€100,000+ | 12–24 weeks | Very high |
Ahrefs reported in 2025 that 34% of websites lose more than 20% of organic traffic after a poorly managed redesign. Every changed URL needs a permanent 301 redirect; otherwise Google encounters 404s and gradually demotes pages.
Export indexed URLs from Search Console before launch and map old to new. After go-live, monitor coverage for 90 days and fix every 404. A structured technical SEO plan protects existing value and speeds Googlebot’s recrawl.
These two SMEs invested in structured redesigns and measured the results over six months.
“Our old WordPress website dated from 2019 and loaded in seven seconds. After a complete redesign, better hosting and SEO work, organic traffic rose from 800 to 2,300 visits a month within five months. Quotation requests tripled.”
“We lost 40% of mobile visitors. A mobile-first design, simpler structure and improved forms reduced bounce rate from 71% to 35% and increased qualified leads by 65% within four months. The investment paid back in three months.”
Standish Group reported in 2024 that 68% of web projects exceed their initial budget. These five avoidable errors recur in most failed redesigns.
The supplier determines 80% of project success (Clutch, 2025). Freelancer, specialist agency or IT services company: the right option depends on budget and complexity. Favour someone experienced in the target CMS who includes SEO from the audit, not at the last minute.
Ask for comparable sector cases. Ensure the quotation covers the audit, UX/UI design, development, SEO migration, CMS documentation and at least three months of post-launch monitoring. A serious web agency itemises every part.
We audit your website, identify growth levers and deliver a tailored redesign covering design, SEO and performance, with measurable results within 90 days.
A sound redesign is a measurable investment. SMEs following audit → specification → UX → development → SEO migration → monitoring see an average 40% traffic and 55% conversion increase within six months (HubSpot, 2025). Do not skip stages; protect existing SEO and choose an accountable supplier.
