How to redesign a website without losing your Google rankings

Devaltech · 8 October 2026 · 6 min read

A new design launches, the owner is delighted, and six weeks later the enquiries have halved. Nothing is wrong with the new site. The old one had rankings the new one did not inherit. Google ranks URLs, not businesses, and a redesign that changes URLs without telling Google starts again from zero.

Before anything moves: take inventory

Crawl the current site and list every URL that Google can reach. Pull the pages that get organic traffic from Search Console and note what each ranks for. Save a baseline of clicks and impressions per page. You cannot tell whether the move worked without it, and you cannot argue with a developer about what broke if nobody wrote down what was there.

The redirect map is the whole job

Every old URL that has a rank, a backlink or a bookmark needs a permanent 301 redirect to the closest equivalent on the new site. Closest means the page about the same thing, not the homepage. This mapping is the core of any migration. Sending everything to the homepage is treated like a soft 404 and throws away what the old page earned. Avoid chains where one redirect points to another, and use 301, not 302, because a 302 says the move is temporary.

Where a page has genuinely no equivalent, let it return a clean 404 or 410 rather than redirecting it somewhere irrelevant. Keep the redirects live for a year at least, which is what Google's own site-move guidance suggests.

A redesign changes how the site looks. A migration changes where it lives. Most disasters are a migration nobody planned for.

Carry the content across, not just the look

Titles, descriptions, headings and the body copy that earned the ranking should come across. A redesign is not a reason to rewrite a page that ranks fourth for a term that matters. Keep the structured data, the canonical tags and the internal links, and check that the new templates still produce them. Then test the new site against Core Web Vitals on a phone before launch. A heavier design that loads slower can cost more in rankings than the old layout ever did.

Launch day and the thirty days after

Launch outside business hours with a rollback ready. Submit the new sitemap in Search Console the same day. If the domain changed, use the Change of Address tool. Then watch: 404s, crawl errors, coverage and the pages from your baseline. A temporary dip is normal. A page that never recovers is a missing or wrong redirect, and it is findable if you wrote the inventory down.

If you already launched and the traffic fell, the same steps work backwards. Find the old URLs that used to bring visitors, check what they do now, and put the redirects in. It is faster than most people expect, and it is exactly the kind of job a speed and SEO rescue is for.
