A redesign can alter the pages and signals that search engines and visitors rely on. Changing a layout is different from changing URL structure, content, or the platform, but projects often involve several changes together. SEO migration planning helps the team understand those dependencies before launch rather than diagnosing missing pages afterward.
If you want support applying these decisions, explore our website redesign service service.
Build an inventory before making changes
Collect existing URLs and identify important pages using available search, analytics, and backlink data. Include pages outside the main navigation when they have a useful role. Decide which remain, which are consolidated, and which genuinely need removal. Do not map every old URL to the homepage as a convenience. A destination should reflect the original page’s purpose closely enough to remain useful for the visitor.
Create a URL map with clear decisions
For every changed address, record the intended destination and the reason. Keep existing URLs when there is no useful reason to change them. For permanent moves, Google recommends appropriate permanent redirects and discourages unnecessary chains. That technical choice belongs within a wider content decision: a redirect cannot replace a relevant page that has been removed without a suitable equivalent.
Preserve important page information
Review titles, descriptions, headings, internal links, canonical settings, and relevant structured data on the new templates. Check that important content remains available and that staging restrictions do not accidentally reach production. A page can look correct while its settings tell search engines not to index it. Establish a checklist for shared templates and a separate review of high-priority pages rather than relying on one general visual inspection.
Test the migration before launch
Check a sample of redirects and important journeys, then broaden the test to the full agreed mapping. Confirm that destinations load correctly and internal links point directly to the intended URLs where practical. Test forms and analytics alongside search controls, since an accessible website that loses enquiry tracking still creates a reporting problem. Record issues, owners, and resolution evidence so the team can make a reasoned launch decision.
Monitor afterward without promising zero fluctuation
Review indexing, crawl errors, traffic to important pages, and conversion behavior after launch. Search visibility can fluctuate during a move, and planning does not guarantee that every position remains unchanged. Compare the data with your baseline and investigate specific problems rather than reacting to one day’s movement. Keep the URL mapping and implementation notes available; they provide valuable context when a post-launch issue appears.
