SEO Migration Services

Our SEO migration services protect the organic traffic you have already earned when you replatform, redesign or move domain. Migrations lose rankings in predictable ways: missing redirects, changed URLs nobody mapped, templates that drop content or structured data, and staging settings that go live by mistake. We crawl the current site, map every URL that matters to its new home, test staging before launch and monitor closely after it, with a recovery plan ready if anything moves the wrong way. We know what goes wrong.

    What are SEO migration services?

    SEO migration services protect a website's search rankings and traffic when it changes platform, design, URL structure or domain. The work covers redirect mapping, pre and post-launch crawls, staging QA, monitoring and recovery. It is a specialist part of our SEO service, run by the same team that handles technical SEO for regulated brands.

    What goes wrong

    Website migration SEO starts before launch

    Most traffic lost in a migration is lost in planning, not on launch day. A URL structure changes and nobody maps the old addresses. A new template drops the copy that made a category page rank. Internal links still point at old URLs and send every visit through a redirect. The staging site’s noindex tag goes live with the new build. We start with a technical SEO audit of the current site, so we know which pages, links and templates carry your traffic, then build the redirect map and launch checklist from that. A migration is a technical project with commercial stakes, and we run it that way.

    How we work

    How our SEO migration services work

    We join as early as you let us, ideally while the new site is still being specified. We benchmark rankings, traffic and links, crawl the current site and build the redirect map with your developers. A backlink audit shows which old URLs carry your strongest links, so none are left behind. Staging is checked against the launch checklist, and after go-live we monitor Search Console and crawl data until performance settles. Progress is reported in AgencyMindHub. To plan a migration, talk to our team.

    Questions

    Website migration SEO, answered

    What is an SEO migration?

    An SEO migration is any change to a website that can affect how search engines find, understand and rank it. That includes moving to a new platform, a redesign, a change of URL structure, merging sites or moving to a new domain. SEO migration work protects existing rankings and traffic by planning redirects, checking the new build and monitoring after launch.

    When should SEO be involved in a website migration?

    As early as possible, ideally while the new site is still being specified. Many migration problems are decided in planning, such as URL structure, which content is kept and how templates are built. Bringing SEO in after the build means fixing those decisions late or living with them. At the very least, the redirect map and staging checks should be done before launch.

    Will we lose rankings when we change domain?

    Some movement is common while search engines process a domain change, but a large or lasting loss is usually a sign that something was missed. Mapping every important URL with a single 301 redirect, keeping content and internal links intact, updating Search Console and monitoring closely after launch gives the new domain the best chance of keeping the rankings the old one earned.

    What is a redirect map?

    A redirect map is a list that pairs every important URL on the old site with its closest equivalent on the new one, so each can be sent there with a permanent 301 redirect. It is built from crawl data, analytics and backlink data, so pages that earn traffic or links are covered. The map is tested on staging before launch and checked again afterwards.

    Can you help if we have already migrated and lost traffic?

    Yes. We compare the old site with the new one using archived crawls, analytics and Search Console data to find what changed, such as missing redirects, dropped content, broken internal links or indexing settings left on from staging. Fixes are then made in order of the traffic at stake, and recovery is tracked page by page in AgencyMindHub.
