Yes, a website redesign can affect Google rankings, but losing visibility is not an inevitable consequence of redesigning.
The biggest risks usually arise when a new site changes or removes things Google already understands: URLs, useful content, internal links, page titles and relationships between pages.
A visually impressive new site can therefore perform worse in search if the migration is handled carelessly.
Google warns that visibility can fluctuate temporarily during a site move and recommends permanent server-side redirects when URLs change.
The mistake is treating the old website as disposable
When organisations redesign a website, attention naturally moves towards the new version.
The old site may look outdated, but it contains information worth examining before anything is removed.
- Which pages receive organic traffic?
- Which URLs appear in Google?
- Which pages have external links pointing to them?
- Which articles answer useful questions?
- Which service or location pages already perform?
- Which pages receive almost no traffic and add little value?
This creates a simple principle: redesign the experience, but understand the existing search footprint before changing the architecture.
What happens when a URL changes?
Imagine your existing page is /website-design-london/ and the redesigned site moves that content to /services/web-design/.
If the old URL simply disappears, visitors following an old link may reach an error page and search engines have to work out what happened.
A permanent redirect tells browsers and search engines where the content has moved.
Google recommends server-side permanent redirects where possible and advises redirecting old URLs to the most relevant new destination rather than sending everything to the homepage.
Do not automatically keep every old page
Protecting search visibility does not mean preserving a poor website forever.
A redesign is often a good opportunity to remove duplication and improve weak content.
The important part is making deliberate decisions.
Three old pages covering almost the same subject might become one stronger page. If so, the old URLs can point to that consolidated resource where appropriate.
A page about a discontinued service may genuinely deserve removal.
A strong service page attracting relevant enquiries probably deserves much more caution.
Internal links matter too
Migration planning tends to focus on redirects, but the links inside the website also help users and search engines understand how pages relate.
After changing the structure, update internal links so they point directly to the new URLs rather than relying indefinitely on redirects.
Google explicitly recommends updating internal links after a site move.
Local visibility needs particular care
For a local organisation, service and location pages can be commercially important.
Suppose a South East London business has developed useful visibility around a particular service and area. Replacing several specific pages with one vague ‘What We Do’ page may remove much of the context that helped both visitors and search engines understand the offer.
That does not mean producing dozens of near-identical location pages.
It means preserving genuinely useful geographic and service information when it reflects the organisation’s real work.
What should be checked before launch?
At minimum, a redesign should account for existing URLs, redirects, metadata, internal links, sitemap changes, indexing controls and key forms or conversion routes.
Google also recommends submitting the new sitemap through Search Console following a site move.
The larger or more search-dependent the website, the more important the migration plan becomes.
Design and SEO should not be separate conversations
SEO migration is sometimes treated as a technical job to perform once the designers have finished.
By then, important structural decisions may already have been made.
A better process considers search behaviour alongside user journeys while the new architecture is being planned.
That allows the website to become clearer without accidentally discarding useful search equity.
