A redesign changes how a site looks. What Google cares about is what is at each address and whether the address still works. Keep those stable and rankings come along for the ride.
Why do redesigns lose traffic?
Almost always one of three things: URLs changed and were not redirected, so ranked pages now return 404; on-page signals were lost, a page's title or H1 was rewritten or removed in the redesign; or content was cut, thin pages deleted without redirecting the traffic they held. Every one is preventable with a checklist.
What has to be preserved?
- URLs. Every page that has a URL now should have the same URL after, or a 301 to the page that replaces it.
- Titles and headings. The page title tag and the main H1 carry ranking weight. Keep the wording, improve it, but do not casually drop the keyword a page ranks for.
- Metadata. Meta descriptions, canonical tags, Open Graph, and any schema markup. Carry it over, do not rebuild from memory.
- Internal links. The links between your pages tell Google which are important. Rebuild the same link structure, at minimum.
- Content. If a page ranks, the redesign should not quietly halve its word count.
How do you map URLs?
Export a full list of the current URLs, usually from the XML sitemap plus a crawl plus the top pages in Search Console and Analytics. For each one, decide: stays the same, redirects to a new page, or is retired with a 301 to the nearest relevant page. That spreadsheet becomes the redirect map, loaded before launch so no request ever hits a dead end.
What checks happen before launch?
On the staging site: crawl it and compare against the old crawl for missing pages, broken links and orphaned content. Confirm every mapped redirect resolves in one hop. Check that titles, H1s and metadata match the plan. Validate the schema. Confirm the staging site is noindex so it never gets crawled, and that the switch to live flips it back to indexable.
What do you watch after launch?
Submit the new sitemap in Search Console and request indexing for the priority pages. Then, for two to four weeks, watch the Coverage and Pages reports for a spike in 404s or "crawled, not indexed", and watch Performance for any query that drops. A small dip in week one is normal recrawl noise; anything still down at three weeks gets investigated.
How long until rankings settle?
Usually two to four weeks to return to the previous position, often a little better because the new site is faster and cleaner. This is the core of every redesign project I take on, and the measured before-and-after is part of the deliverable.
