A website redesign is the planned rebuild of an existing site’s structure, content, design and technology so that it serves today’s customers and business goals better than the old one. Done well, it keeps what the current site has earned in search, links and habits, and fixes what holds it back; done badly, it swaps one set of problems for a prettier one.

This guide covers when a redesign is worth it, what to settle before you start, what the work involves in practice, what drives the cost, the European rules that apply, how to choose a partner and how to measure the result.
What is a website redesign?
A website redesign is a project that changes how a site is organised, what it says, how it looks and, often, what it runs on, while the business and most of its audience stay the same. That last point separates it from building a first website: a redesign starts with assets to protect.
The scope ranges from a visual refresh on the same platform to a full rebuild with a new structure, new content and a new content management system. Most projects sit in between. The useful question is not “how much do we change?” but “what must the new site do that the old one cannot?”
At Odduel, a creative and technology agency in Barcelona and São Paulo, our website redesign service begins with that question, in writing, before anyone opens a design file.
In short: a redesign earns its place when the current site blocks a goal you can name. Settle goals, audience and success measures first; audit what exists; protect search value with a redirect plan; build and test on a staging copy; launch carefully; then measure against the benchmarks you recorded at the start.
When does a business need a website redesign?
Redesign when the site stops doing its job, not when it merely looks dated. The clearest triggers are business changes the site cannot carry: a new offer, a new market, a rebrand, a sales process that has moved online, or a team that cannot update content without a developer.
Technical triggers are just as valid. A platform that is no longer maintained, pages that fail accessibility requirements, slow loading on phones and a checkout that loses customers all justify a rebuild. Our article on the signs your website needs a redesign goes through them one by one.
A redesign is usually the wrong answer when one page underperforms, when the problem is traffic rather than the site, or when the real gap is content nobody has written yet. Fix those directly first.
What should you do before a website redesign?
The work before the brief decides most of the outcome. This pre-project checklist is about the business case and the team; the search side has its own checklist, covered later.
- Write the goal in one sentence. For example: more qualified enquiries from a specific sector, or online sales in a second country.
- Name the audience and their top tasks. What do the main visitor groups come to do, and which of those tasks earn the business money?
- Record benchmarks. Traffic, enquiries or sales by page, top search queries, page speed on key templates and accessibility issues. Without a “before”, nobody can prove an “after”.
- Audit the content. List every page and decide: keep, rewrite, merge or remove. This is where most hidden effort sits.
- List integrations. Forms, CRM, booking, payments, stock, analytics and consent tools all need a home on the new site.
- Agree who decides. One person signs off each stage. Committees by email stretch timelines more than any technical issue.
- Set the constraints. Deadline drivers, budget range for internal planning, platforms you must keep and languages you serve.
Teams that do these seven steps get sharper quotes, because a partner can price what is known rather than what is guessed.
Where should a company start with a website redesign?
Start with evidence, not mood boards. Analytics show which pages bring visitors and which ones lose them; search data shows the queries that already work; a short round of conversations with customers and sales staff shows what people look for and fail to find.
From there, write a brief of one or two pages: goal, audience, top tasks, content scope, integrations, constraints and how success will be measured. That brief is what you send to potential partners, and it becomes the yardstick for every decision afterwards.
What does a website redesign involve in practice?
A typical redesign runs through six stages. The names vary between agencies; the substance should not.
| Stage | What happens | What you approve |
|---|---|---|
| Discovery | Goals, audience, audit, benchmarks, technical review | The brief and the scope |
| Structure | Sitemap, page types, content plan, redirect map draft | The sitemap and the content plan |
| Design | Key page layouts, design system, responsive behaviour | Designs of the main templates |
| Build | Development, content entry, integrations, accessibility work | A working staging site |
| Test and launch | Quality checks, redirects, speed, forms, analytics, go-live | The launch checklist |
| After launch | Monitoring, fixes, measurement against benchmarks | The 30- and 90-day reviews |
Our step-by-step website redesign process describes each stage in more detail, including who does what.
Content is the critical path
Design and code rarely delay a launch; content does. Assign each page an owner and a deadline at the structure stage, and decide early whether copywriting is part of the partner’s scope.
Build on a staging copy
All work happens on a closed staging site that search engines cannot index. Real content goes in as early as possible, so layouts are judged with true text lengths and real photographs rather than placeholders.
How do you protect search rankings during a redesign?
Protect rankings by keeping what earns them: the addresses, the content and the links. Every old address that changes needs a permanent (301) redirect to its closest new equivalent, live from the moment the new site launches. Google sets out the method in its guidance on site moves with URL changes.
Beyond redirects, keep the topic and depth of pages that rank, carry over titles and structured data, keep the site closed to indexing only while it is on staging, and submit the new sitemap at launch. The full SEO checklist is in our guide to SEO during a website redesign.
What drives the cost of a website redesign?
The cost of a redesign follows the amount of work in a handful of areas, so two sites that look similar can be priced very differently. A fixed quote follows a short brief; until then, these are the lines to understand.
| Cost driver | Why it moves the price |
|---|---|
| Number of page types | Each template is designed, built and tested; ten page types cost more than four |
| Content work | Rewriting, translating and entering content is often the largest share |
| Integrations | Each connection to a CRM, booking, payment or stock system adds build and test time |
| Languages | Every language adds content, addresses, hreflang and checks |
| Custom features | Configurators, portals and calculators are small software projects in their own right |
| Platform change | Moving to a new system adds migration of content, users and data |
| Accessibility and performance targets | Meeting them properly takes design and development time from the start |
When you compare quotes, check that each one covers the same content scope, the same integrations, testing, the redirect plan and support after launch. A quote that omits them is not cheaper; it moves the cost to later.
Which European rules affect a website redesign?
A redesign is the natural moment to bring a site into line with the rules that apply to European businesses.
- Accessibility. Since 28 June 2025, the European Accessibility Act applies to many consumer-facing digital services, including e-commerce. The practical reference is WCAG 2.2 at level AA; small micro-enterprises providing services have exemptions, so check where you stand.
- Data protection. Forms, analytics and marketing tools must follow the GDPR: a clear legal basis, a privacy notice, and consent before non-essential cookies or trackers load.
- Consumer information. Online stores must show prices including VAT, delivery costs and the right of withdrawal in a clear way.
Treat these as design requirements from the first sketch. Retrofitting accessibility after launch costs far more than building it in.
Website redesign best practices
These habits separate redesigns that pay back from those that merely look new.
- Change only what has a reason; keep what works, including page addresses that rank.
- Design with real content, at real lengths, in every language you serve.
- Build a small design system of reusable components rather than one-off pages.
- Make the site fast on a mid-range phone, not only on the office laptop.
- Give the team an editing experience they will actually use, with training.
- Launch in phases where the scope is large.
- Plan the first three months after launch, with budget for fixes and improvements.
Should you redesign with an agency or in-house?
Choose an agency when the project needs skills your team does not hold every day: strategy, design, development, content and search working to one plan. Keep work in-house when you have those skills and the time, or when the change is small and frequent rather than a single project.
Many businesses mix the two: an agency leads the redesign, and the internal team takes over the content and day-to-day updates afterwards. Our comparison of a website redesign by an agency or in-house weighs the options in detail.
How do you choose a website redesign partner?
Look for evidence of the kind of work you need, a clear process and honest answers about cost drivers. Ask these questions before signing:
- What do you need from us before you can quote, and what happens if the scope changes?
- How do you protect search rankings, and who builds the redirect map?
- Who writes, edits and enters the content?
- How do you test accessibility and speed, and to which standard?
- What happens in the first 90 days after launch?
- Who owns the code, the designs and the accounts at the end?
Answers that are specific and written down are a good sign. Vague promises about results are not.
How do you measure whether a website redesign works?
Measure against the benchmarks you recorded before the project, using the goal written in the brief. If the goal was qualified enquiries, track enquiries by source and their quality, not only visits.
Review at 30 days for problems (errors, missing redirects, broken forms), at 90 days for trends (search visibility, conversion rates on key pages) and at six months for the business case. Expect a short dip in search while engines process the changes; a decline that deepens after the first weeks points to something that needs fixing.
Measure page speed against Google’s Core Web Vitals, and repeat the accessibility checks you ran before launch. A redesign that passes on launch day can drift as content is added, so schedule a check each quarter.
Questions people ask
How long does a website redesign take?
Timelines depend on the number of page types, the content work, integrations and how quickly decisions are made. A focused redesign on the same platform is far shorter than a rebuild with new content, a new system and several languages. Content and approvals usually set the pace, so planning them early shortens the project more than anything else.
What is the difference between a redesign and a refresh?
A refresh changes the look of a site: typography, colours, imagery and some layouts, usually on the same platform and structure. A redesign goes further and changes structure, content and often the technology. A refresh suits a site that works but looks dated; a redesign suits a site that no longer serves its goals.
Will a website redesign hurt my SEO?
It does not have to. Rankings fall when addresses change without redirects, when content that ranked is cut, or when the site launches with indexing blocked. A redirect map built early, content that keeps its topic and depth, careful launch checks and close monitoring for the first month protect the search value the old site earned.
How often should a business redesign its website?
There is no fixed cycle. Redesign when the site blocks a business goal, when the platform is no longer maintained, or when accessibility, speed or security can no longer be fixed in place. Between redesigns, steady improvements to content, speed and conversion keep a site useful for longer and make the next rebuild smaller.
What should a website redesign brief include?
A good brief states the goal, the audience and their top tasks, the content scope, the integrations, the languages, the constraints and how success will be measured. One or two pages are enough. It lets partners quote the same work, and it gives everyone a reference point when decisions get difficult during the project.
