Rankings are lost in a redesign for one reason: the new site is built first and the old addresses are dealt with afterwards. By then the pages that earned the traffic have been renamed, merged or quietly dropped, and Google is looking at a site it does not recognise. The fix is sequence, not luck. Audit, protect, rebuild — in that order.
1. Audit: know what is earning the traffic
- Export every page from Search Console (Pages report) and from the sitemap. This is your inventory.
- For each page, note impressions, clicks and the queries it ranks for over the last 12 months.
- List the pages other sites link to. These are the ones you must not break.
- Record current speed and Core Web Vitals so you can prove the new site is better, not just different.
- Save the current title tags and meta descriptions — they are part of what ranks.
2. Protect: decide what cannot change
From the audit, write down the URLs you are not allowed to break. For each one, decide: keep the address, or move it to a better one with a redirect. Build the redirect map now, in a spreadsheet, old address next to new. Every page that ranks goes to the single most relevant new page. Nothing goes to the homepage unless the homepage is genuinely the replacement.
Keep the content that ranks. Redesign means new layout, not new words for their own sake. If a page brings enquiries with its current text, improve it carefully rather than rewriting it from scratch.
3. Rebuild around the map
- Structure the new site so the protected pages have natural homes, then design around that structure.
- Carry over titles, descriptions, headings and structured data, and improve them where the audit showed weakness.
- Build fast by default: images sized for the page, no unused scripts, server-rendered pages. Speed is a ranking factor and a conversion factor.
- Set up analytics and conversion tracking on the new site before launch, so the first week of data is not lost.
4. Verify before you switch
On the staging site, test every line of the redirect map with a crawler. Check that the sitemap lists only real pages, that robots rules will allow indexing on launch day, and that forms, phone links and tracking all fire. Only then switch DNS. Keep the old hosting live for a few weeks; you are changing where the domain points, not deleting anything, so rolling back takes minutes.
5. The first month after launch
Submit the new sitemap in Search Console, then watch Coverage and Pages for 404s you did not expect — there are always a few. Fix them with redirects as they appear. Compare clicks week by week against the audit numbers. A small dip for two or three weeks is normal while Google recrawls; a sustained fall means a redirect or a content change needs attention.
Our website redesign service is built around exactly this sequence, which is why the redirect map and the ranking audit are included in the price rather than sold as extras.
