Introduction

A website migration can improve design, performance and manageability. It can also create serious problems when important URLs, content or technical signals are changed without a plan.

A migration may involve:

  • rebuilding the site on a new platform
  • moving to a new hosting provider
  • changing the domain
  • restructuring page URLs
  • combining several websites
  • switching from HTTP to HTTPS
  • moving content into a new navigation structure

The level of SEO risk depends on what changes.

A hosting move that preserves the same URLs is different from a rebuild that changes every page address.

For businesses planning web development in Osborne Park, migration planning should begin before the new website is built, not immediately before launch.

Record the current website

Before changing anything, create an inventory of the existing site.

Record:

  • indexable page URLs
  • page titles
  • meta descriptions
  • headings
  • canonical tags
  • images
  • downloadable documents
  • inbound links where known
  • current organic traffic
  • high-performing landing pages
  • forms and integrations
  • redirects already in place

This baseline helps identify what must be preserved, improved or intentionally removed.

It also prevents important content from being forgotten simply because it is not visible in the main menu.

Decide which URLs should remain

Keeping established URLs is often the simplest approach when the subject of the page has not changed.

For example: ‘/services/commercial-cleaning/’ does not need to become:’/what-we-do/cleaning-services-for-commercial-businesses/’,

merely because the website is being redesigned.

Changing URLs adds migration work and creates opportunities for errors. A new URL structure may still be worthwhile when the existing structure is genuinely poor, but changes should have a clear reason.

Create a URL mapping document

Every important old URL should be mapped to its best new destination.

The relationship should be as close as possible.

Do not redirect dozens of unrelated old pages to the home page. This provides a poor user experience and may not preserve the relevance of the old pages.

A mapping might look like:

Old: /our-services/websites/
New: /website-design/

If a page is removed because the service no longer exists, consider whether there is a relevant parent page or explanatory replacement.

A genuine missing page may sometimes return a 404 or 410 response. Redirecting everything indiscriminately can create more confusion than it solves.

Use permanent redirects correctly

A permanent server-side redirect tells browsers and search engines that a resource has moved.

For most permanent page replacements, a 301 or 308 redirect is appropriate.

Redirects should:

  • point directly to the final destination
  • avoid unnecessary chains
  • remain in place long enough
  • preserve query requirements where relevant
  • be tested before and after launch

A redirect chain such as:
old URL -> temporary URL -> new URL

creates additional processing and more places for something to fail.

Google provides specific guidance for site moves and URL changes, including redirects, updated internal links and monitoring.

Preserve important content and meaning

A new website should not automatically discard established content.

A page that ranks because it thoroughly explains a service may lose visibility if the replacement contains only a short marketing paragraph.

Design and content must be planned together.

When rewriting, preserve:

  • the main subject
  • useful supporting detail
  • important customer questions
  • evidence and examples
  • relevant internal links
  • clear location context
  • the purpose of the page

The replacement can be clearer and more useful without becoming thin.

Our article on website content builds authority and trust⁠n explains why useful depth matters.

Update internal links

Internal links should point directly to new URLs rather than relying on redirects.

Review:

  • navigation menus
  • footer links
  • content links
  • buttons
  • image links
  • canonical references
  • structured data
  • XML sitemaps
  • hreflang references
  • downloadable documents where practical

Search-and-replace tools can help, but automated replacements must be checked carefully to avoid changing unrelated text or encoded data.

Protect analytics and conversion tracking

A successful visual launch can still disrupt measurement.

Confirm that the new site retains or correctly replaces:

  • Google Analytics
  • Search Console verification
  • advertising conversion tags
  • form conversion tracking
  • ecommerce tracking
  • cookie consent controls
  • event tracking
  • call tracking where used

Record benchmark data before launch so changes can be evaluated afterwards.

Test the staging website

A staging environment allows the new website to be reviewed before public launch.

Check:

  • mobile layouts
  • forms
  • checkout processes
  • links
  • redirects
  • robots directives
  • canonical tags
  • structured data
  • page titles
  • performance
  • accessibility basics
  • browser compatibility

Staging websites should generally be blocked from indexing. That block must not accidentally remain when the production site launches.

One of the most serious migration mistakes is publishing a new website with a site-wide noindex instruction copied from staging.

Submit and monitor after launch

After launch:

  1. confirm important pages return the correct status
  2. test redirects
  3. submit the updated XML sitemap
  4. inspect key URLs in Search Console
  5. monitor indexing and traffic
  6. check forms and ecommerce
  7. watch server logs and error reports
  8. correct unexpected 404 errors

Some ranking movement can occur while Google recrawls changed URLs. Google notes that a site move can take time to process, particularly for larger websites.

Monitoring should continue for weeks rather than stopping once the home page looks correct.

Our guide to why websites should be reviewed regularly⁠ is useful for the post-launch review phase.

You may also want to read single-page versus multi-page websites⁠ if the rebuild changes the overall content architecture.

Hosting-only moves need planning too

A hosting change that preserves URLs usually has less search risk, but it still requires preparation.

The new environment should be tested for:

  • DNS configuration
  • SSL
  • performance
  • server responses
  • redirects
  • email dependencies
  • scheduled tasks
  • firewall behaviour
  • CDN configuration

Google provides separate guidance for changing hosting without changing visible URLs.

For businesses arranging web development in Osborne Park, the safest migration is one where responsibilities, redirect mappings and launch checks are agreed before work begins.
