Website redesign: the 2026 guide (when, how, how much)

A website redesign is one of the most profitable — or riskiest — investments a business can make online. Done well, it revives traffic, enquiries and image. Done badly, it can erase years of SEO in a single launch. Here's how to decide, scope and succeed with yours.

The unmistakable signals A site due for a rebuild is easy to spot: over three seconds to load, a layout that breaks on mobile, visibly dated design, copy nobody stands behind anymore, absence from Google's first pages — and now a new symptom: your business never appears in ChatGPT or Perplexity answers when people search for your services. Tick two of those boxes and a redesign is no longer cosmetic: your site is costing you customers every week.

Redesigning doesn't mean throwing everything away The first serious step is an audit: what do we keep, fix, or rebuild? Some pages rank and generate enquiries — they must be preserved or improved with care. Others never brought anything. A technical and SEO audit upfront avoids paying to rebuild what worked and keeping what dragged the site down.

Trap #1: losing your rankings It's the classic redesign tragedy: the new site is beautiful, and traffic collapses. The cause, almost always: URLs changed without 301 redirects, ranking content deleted, tags rewritten without a plan. The rule: map every existing URL and its positions BEFORE the redesign, redirect each old address to its new equivalent, and track positions week by week after launch. It's methodical work — and it's what separates a serious agency from a graphic designer.

Use it to reach the 2026 standard A redesign is the moment to add what your current site can't do: proper multilingual with hreflang if your clientele is international, structured data for Google's rich results, an architecture built for local SEO if you serve an area, and GEO optimisation to exist in AI engines' answers. Rebuilding the same thing but prettier would be a waste: the standard has moved.

Cost and timeline Depending on scope — brochure, e-commerce, multilingual, booking — a professional redesign runs from a few thousand euros to several tens of thousands for complex platforms. Timeline: a few weeks for a well-scoped brochure site, several months for a rich project. Beware both extremes: the abnormally low quote means a duplicated template and ignored SEO; the project with no deadline means a site that never ships.

Our method We start every redesign with an audit of the existing site and an SEO map, we deliver a fast site, multilingual where needed, optimised for Google and for AI — and we track positions after launch until the transition is consolidated.
