Preserve the customer’s route through the redesign
The release is not complete because the new home page looks right. Someone may arrive through an old service link, a saved product page or a PDF cited in an email. Your migration plan needs a decision for those routes as well as the new navigation.
Google’s site-move guidance describes preparing a URL mapping and monitoring the old and new addresses. It also warns that visibility can fluctuate while changes are processed. A checked migration reduces avoidable mistakes; it cannot promise unchanged rankings.
The checklist here is a practical release plan for a business website. It is not a complete specification for every platform. A large catalogue, a changed domain or a complex application may need a more detailed migration design.
Make one inventory before making design decisions
Collect the addresses that matter to the first release and the people responsible for them. Include service pages, product records, useful articles, downloads and any landing pages linked from campaigns. Bring together the available CMS export, sitemap, analytics and link information rather than assuming one list is complete.
For each resource, record its purpose and what should happen after launch. A spreadsheet can be sufficient for a small site if it has an owner and is kept in step with the implementation. An old address needs a decision, not just a row marked “SEO”.
| Old address, illustrative | Decision | Expected launch result |
|---|---|---|
| /services/inspection/ | Keep | Same useful page, successful response |
| /old-maintenance/ | Move to the equivalent service | Permanent redirect to /services/maintenance/ |
| /downloads/specification.pdf | Retain or replace the file deliberately | Working file or relevant file replacement |
| /expired-offer/ | Remove with no suitable successor | Deliberately configured not-found or gone response |
These addresses are invented examples. The right destination depends on the actual information a visitor expected to find. Do not use the table as a production redirect configuration.
Decide what genuinely needs a new URL
A redesign does not require every address to change. Retain useful paths unless there is a clear reason to move them. If the business combines two overlapping pages, explain which information survives and how the combined page serves both groups of visitors.
For permanent moves, Google’s redirect documentation identifies server-side 301 and 308 responses as permanent redirects. The status and destination should match the actual decision. A temporary interruption is not the same decision as retiring an address.
Ask the developer for a testable mapping, not a rule that silently sends every unknown address to the home page. Where the destination is still undecided, keep that item visible as unresolved instead of approving it as migrated.
Check the destination, not only the first response
For each mapped move, inspect the old address, the destination it returns and the final page. The destination should load the intended content. A redirect that ends at another redirect, a missing page or the wrong language is not a successful customer journey just because the first status looks correct.
Use a small review record with columns for the old URL, expected destination, observed destination, final status, content match and reviewer. Test a representative range before launch, then validate the complete agreed mapping with a suitable crawler or script. Keep manual checks for meaning: a status code cannot decide whether the replacement answers the original question.
Align internal links and canonical signals
Google describes redirects and canonical annotations as strong canonicalization signals, with sitemap inclusion a weaker signal. Its canonical documentation also recommends consistent internal links and compatible signals. These are signals to Google, not commands that guarantee a particular search result.
For the release review, pick one final address for each intended public page. Check that menus, relevant content links, canonical annotations and the sitemap agree with that decision. For language versions, confirm that equivalent links point to actual pages and have not been copied from a different region.
Put this check in the migration record so a content editor can repeat it later. A technically correct launch can be undermined if a subsequent edit restores links to an obsolete address.
Separate staging restrictions from launch settings
A test copy needs its own access plan. Google’s robots.txt introduction explains the role of crawl rules and their limitations. A robots.txt rule is not a password or a general confidentiality control.
Before publication, list the restrictions that belong only to the test environment. Verify the intended live response, metadata and access from a signed-out browser. Conversely, keep genuinely private areas protected after launch. Treat public indexing decisions and access control as separate checks.
Rehearse the launch and its recovery path
- Identify who can deploy, change redirects and restore the previous version.
- Confirm what is backed up and how newly received enquiries or orders are protected during recovery.
- Set a point after which live content changes need to be included in the migration.
- Test the primary enquiry or purchase journey on the published site.
- Record the launch version, known issues and the owner of each follow-up check.
A rollback needs a data decision, not just a copy of the old files. For example, restoring an earlier database without handling new orders can create a business problem even when the old design returns correctly. Agree the recovery process for the systems involved rather than improvising it during an outage.
Monitor evidence after publication
Compare like periods and page groups, with notes for the launch and any other changes. Separate a delivery failure, a reporting change and a change in search visibility. One daily total cannot tell you which of those occurred.
Google advises retaining migration redirects for as long as possible, generally at least a year. Record that requirement with the person who maintains the site. If you later propose removing a redirect, review its purpose and continued use rather than deleting it because the redesign project has closed.
Use the redesign brief to share the existing site and the important journeys. If the URLs are already broken, begin with the SEO brief and an inventory of the affected addresses before commissioning another visual change.

Коротко о важном
Do I need redirects when the design changes but the URLs stay the same?
A visual change alone does not require a redirect. Keep the existing useful URLs where possible, then check that they still return the intended content and status. Redirects are needed for the addresses you deliberately move.
Can all removed pages redirect to the home page?
That is not a sound default. Choose a relevant replacement where one exists. Google warns that unrelated redirects can be treated as soft 404s. A genuinely removed resource without a replacement may need a proper 404 or 410 response.
How long should migration redirects remain?
Google’s guidance says to keep them as long as possible, generally at least one year. Visitor bookmarks and external links can justify keeping useful redirects longer. Record their ownership so a later cleanup does not remove them accidentally.
