A redesign can improve a site, but it can also damage search visibility if URLs, titles, content, and redirects are handled badly.
Map Existing URLs
Export the current important URLs before redesign work starts. Decide whether each page stays, redirects, or is removed.
Keep Useful Content
Do not remove strong content just because the new design is cleaner. Rewrite and reorganise where needed, but preserve pages that earn traffic or enquiries.
Plan Redirects
If URLs change, create 301 redirects from old URLs to the closest matching new pages.
Test Before Launch
Check metadata, headings, mobile layout, forms, sitemap, robots settings, and redirects before switching the new site live.
A redesign should improve the site without making search engines rediscover everything from scratch.
Build an Inventory Before Design
Export current URLs, titles, descriptions, headings, canonicals, status codes, structured data and organic landing-page performance. Include PDFs and campaign pages that still receive links. Mark which pages must remain, merge or disappear, and identify the queries and conversions each important page supports.
Keep URLs Stable Where Possible
A new layout does not require a new address. When a URL genuinely changes, map the old page to the closest equivalent with one permanent redirect. Do not send every removed page to the homepage, create redirect chains or rely on JavaScript navigation. Preserve useful content and internal anchor text rather than replacing it with generic marketing copy.
Test a Crawlable Staging Copy
Protect staging with authentication and keep it out of search results, but allow your own crawler to inspect it. Compare titles, canonicals, robots directives, headings, links, image alt text and structured data. Test mobile layouts and Core Web Vitals before launch, not after rankings move.
Monitor the Launch
Submit the updated sitemap, inspect key URLs in Search Console and watch 404s, redirect errors, impressions and conversions. Keep the old URL inventory available for several months. Fix accidental removals quickly, but do not reverse sound changes merely because normal recrawling causes short-term movement.
