A redesign should improve how a site performs, not reset it. The risk is not the new design — it is losing the pages, links, and content that search engines already value. A redesign planned around those assets keeps the visibility you have earned and builds on it.
Audit your existing pages, redirect every URL that moves to its closest match, and verify before and after launch — that is how a redesign keeps its search visibility.
Audit what you have before changing anything
Before the first design draft, list every page that brings visitors, enquiries, or sales. Analytics and search console data show which pages matter; a crawl of the site shows what exists. Mark the pages that must keep their content and purpose, the ones that can be merged, and the ones that can retire.
Note what already works: pages that rank for useful searches, content that answers real customer questions, and URLs that other sites link to. These are assets. A good redesign improves them, not replaces them.
Map every URL that moves
For each old page, decide its destination: the same URL, a new URL with a redirect, a merged page, or retirement. Every page that moves needs a permanent redirect from the old address to the most relevant new one — not the homepage, which tells search engines the old content is gone.
Keep the content substance on important pages. Renaming a service is fine; removing the explanation of that service is not. If a page must lose content, check whether another page now covers the same questions — if not, carry the substance across.
Check the new site before switching
Before launch, verify on a staging version: every redirect works, no internal link points at a removed page, titles and descriptions are carried over or improved, and the new site is crawlable. Run the same checks again the week after launch.
After switching, watch analytics and search console for a few weeks. A small fluctuation is normal; sustained drops on specific pages usually mean a lost redirect, a missing section, or content that did not survive the move — all fixable if caught early.
Audit your existing pages, redirect every URL that moves to its closest match, and verify before and after launch — that is how a redesign keeps its search visibility.
