Website migration without losing SEO: change your design, CMS or domain under control

A redesign or platform change can sink organic traffic if URLs change without a plan. We plan the migration and check every page before and after.

Migrating a website without losing SEO means changing its design, CMS or domain while keeping what Google already knows about it: URLs, content and signals. If you are redesigning or replatforming, Nexura Digital builds the URL inventory, the 301 redirect map and a full backup, verifies the site page by page and compares before and after in Search Console. You can start with a 7-day trial focused on the inventory and redirects.

What a controlled migration includes

URL inventory

We gather every URL that matters: those a crawler such as Screaming Frog finds, those with clicks in Search Console, visits in GA4 or external links, and those in your sitemaps. Anything missing from the inventory ends up without a redirect.

301 redirect map

  • Each old URL points to its closest equivalent, not the home page
  • Direct redirects, no chains
  • A documented decision per page: keep, merge or remove
  • Removed pages with no equivalent return a 404 or 410

Backup and staging

A full backup of files and database before anything changes, and the new site on a password-protected staging environment so it isn't indexed too early.

Mistakes that cost traffic

The most common ones

  • Redirecting everything to the home page, which Google may treat as missing pages
  • Launching with the staging site's noindex tag or robots.txt
  • Losing titles, copy or structured data that used to rank
  • Leaving internal links pointing at URLs that redirect
  • Forgetting images, PDFs or language versions

How we work: before, during and after

Before

We validate the inventory and map with you, compare titles, metadata, headings and content across both versions, and review canonicals, hreflang, sitemaps, robots.txt and structured data.

Launch day

We switch on the redirects, remove the staging protections, submit the new sitemaps and crawl the old URLs to confirm each returns a 301 to a page that returns a 200. If you change domains, we use the Change of Address tool in Search Console.

The weeks after

We monitor the Page indexing report, 404 errors and Search Console performance, comparing equivalent periods. Google warns that rankings fluctuate for a while; our job is to catch early any page that doesn't recover.

Do you need a full migration?

You need it if

  • You are changing domain, CMS or ecommerce platform
  • You are redesigning and URLs or content structure will change
  • You are merging sites or moving to a language-based structure

Something lighter will do if

  • You only change colors, fonts or images, without touching URLs or copy
  • Your site gets almost no organic traffic or external links
  • The migration already happened: then you need a recovery audit

The documentation you keep

Five documents

  • A URL inventory with the source of each URL
  • A redirect map ready for your server or CMS
  • Pre- and post-launch checklists
  • A status report for every old URL
  • A before-and-after Search Console comparison

What we do in the 7-day trial

Inventory and redirect map

We tackle the most critical piece: a complete URL inventory of your current site and its redirect map to the new structure. If you have already migrated and see drops, we crawl the old URLs to find and fix broken redirects. Scope, dates and terms are set in writing before we start.

FAQ

Frequently asked questions

Can you redesign a website without losing rankings?

The risk can be reduced a great deal, but it wouldn't be honest to promise zero fluctuation: Google has to recrawl the changes, and a few weeks of movement are normal. With a complete inventory, correct 301 redirects and the ranking content preserved, the site should recover; if a page doesn't, we spot it by comparing data.

How long should redirects stay in place?

Google recommends at least one year, and the safe choice is never to remove them unless they cause problems: they keep sending anyone with an old link to the right page. If you change domains, keep the old one too, because if it expires the redirects stop working.

What do you need from me to get started?

Read access to Search Console and GA4, access to your CMS and hosting or a copy of the site, and the new structure if it exists. We will ask you to approve which pages are merged or removed, because that decision affects your business, not just SEO.

What if I already migrated and lost traffic?

First we diagnose. We crawl the old URLs using your Search Console and GA4 history, look for broken redirects, chains or redirects to the home page, and compare titles and content with the previous version using backups or public web archives. Then we fix the pages that had the most traffic first.
