Website Redesign: When It’s Time, and How Not to Lose Your SEO

2026-08-28 6 MIN READ

A redesign is needed when the site gets in the way of your business — not when you got bored of the colour. The three real criteria are: it does not work properly on mobile, you cannot update it yourself, and it does not produce enquiries despite having visitors.

The biggest risk is not the cost. It is losing overnight the rankings you built over three years, because nobody produced a redirect map.

Not sure whether you need a redesign?

Request a free assessment of your site and we will tell you whether a refresh is enough or a rebuild is warranted.

The seven signs it is time

  1. It does not work properly on mobile. Horizontal scrolling, tiny buttons, a menu that will not open.
  2. It takes over 4 seconds to load on mobile over 4G.
  3. You cannot change text without phoning the person who built it.
  4. It has no SSL or shows a security warning.
  5. The services it describes are not what you sell any more.
  6. It has visitors but zero enquiries. The problem is structure and calls to action.
  7. It runs on unmaintained technology. An old PHP version, an abandoned theme, dead plugins.

Two or three of these means a conversation. Five or more means the site is already costing you.

Refresh or rebuild?

They are not the same project, and the cost difference is large.

 RefreshRedesign
What changesColours, images, copy, small fixesStructure, platform, design, URLs
Typical cost€300 – €1,200€1,500 – €5,000
Duration1–2 weeks4–10 weeks
SEO riskMinimalHigh without proper migration
Right whenThe foundation is sound but it looks datedThe foundation is broken or will not scale

The rule: if the structure and platform hold up, start with a refresh. It costs a third as much and often solves the problem.

Will I lose my rankings?

No, if the migration is done properly. Yes, dramatically, if even one step is skipped.

This is the list you should demand in writing from whoever takes the project.

#StepWhen it happens
1Full inventory of every existing URLBefore starting
2Record of rankings and traffic per pageBefore starting
3Redirect map: old URL → new URLDuring design
4Preserve titles and meta descriptions that performDuring development
5Migrate the copy rather than trimming itDuring development
6Testing on staging, blocked from search enginesBefore launch
7Remove the noindex directive before going liveLaunch day
8Apply 301 redirects, not 302Launch day
9New sitemap submitted to Search ConsoleLaunch day
10Daily 404 checks for two weeksAfter launch

Step 7 is the industry’s most common accident. The site stays invisible for weeks because someone forgot to remove the directive that hid it during testing.

Step 3 is the most expensive to omit. Every old URL that leads nowhere also throws away the external links that pointed at it.

Why did traffic drop after the redesign?

A small dip of 10–15% in the first two or three weeks is normal while Google re-reads your pages.

A drop of more than 30% lasting beyond a month is not normal. The most common causes, in order of frequency:

  • Missing redirects, or all of them pointing to the homepage instead of the matching page.
  • The noindex directive left in from staging.
  • Copy cut back “to make it cleaner”, taking the ranking terms with it.
  • Page titles changed for no reason.
  • Speed degraded by heavy imagery in the new design.
  • Structured data lost, removing stars or prices from results.

All six are fixable. The faster they are spotted, the faster traffic returns — usually within 4–8 weeks.

The process in six phases

PhaseWhat happensDuration
1. InventoryWhat exists, what performs, what is missing3–5 days
2. StrategyNew page structure and user journeys1 week
3. DesignPrototypes for mobile and desktop1–2 weeks
4. DevelopmentBuild, copy, performance2–4 weeks
5. MigrationRedirects, testing, launch2–3 days
6. MonitoringErrors, rankings, conversions30 days

Phase 1 is almost always skipped, and it is the one that saves the project. Without knowing which pages bring you traffic today, you cannot protect anything.

What does a redesign cost?

Project typeRange
Refresh of an existing site€300 – €1,200
Redesign of a 5–10 page corporate site€1,500 – €3,500
Redesign onto a new platform€2,500 – €6,000
E-shop redesign€3,000 – €10,000
SEO migration as its own line item€300 – €900

That last line should appear explicitly in the quote. If it does not, ask who is doing it — and if the answer is vague, add it yourself.

The remaining ranges by project type are in our guide to professional website costs, and what a serious quote must contain is in our guide on choosing a web developer.

When a redesign solves nothing

If your site has no visitors, a redesign will not create them. The problem is visibility, not appearance.

In that case, the same money returns far more when spent on content and local SEO. Start with our guide to local SEO and Google Business Profile.

Equally, if the problem is that you cannot extend it technically, the conversation is about platform rather than design — see WordPress or custom.

Frequently asked questions

How often should I redesign?

There is no rule in years. There is a rule in performance: while the site produces enquiries and updates easily, it does not need one.

Can I keep my existing copy?

Not only can you — you should, at least on pages that perform. Rewriting from scratch is the most underrated risk in the whole project.

Do I have to change my URLs?

Only if there is a reason. If the existing ones are clean and performing, leave them alone.

What happens to the old site?

Keep a full copy of files and database for at least three months after launch.

How long until traffic recovers?

With a proper migration, 2–4 weeks. With a botched one, 2–4 months after the fixes.

Before you say yes to a redesign quote

Ask for three things in writing: the ten-step migration list, the redirect map before launch, and an error check two weeks afterwards.

If all three are in the quote, your risk has all but disappeared.
