SEO Migrations

Relaunch right and keep the revenue you’ve spent years building

A launch should be the moment your website starts working harder for your business, not the moment you start wondering where the enquiries went. We ensure your new website inherits the visibility your old one earned, so you can focus on what’s next instead of recovering what you’ve lost.

The common problem with website migrations

Here’s what usually happens: the website gets designed, built, approved and launched – and only afterwards does anyone ask what happens to rankings. By then the redirect plan is an afterthought, the URLs have already changed, and there’s no benchmark to prove whether anything actually went wrong.

It’s rarely carelessness. Migrations simply fall between teams: developers own the build, designers own the look, and search visibility isn’t anyone’s job unless it’s explicitly someone’s job. One missing redirect. One deleted page that happened to hold your best backlinks. One staging site accidentally left open for Google to crawl. That’s all it takes for you to need to spend six months of clawing back rankings you already owned – while your competitors keep taking the enquiries that would have been yours.

That’s the real cost of migration mistakes. Not “a ranking drop.” Lost pipeline, for months, that’s genuinely difficult to get back.

When do I need SEO migration support?

SEO migration means protecting your commercial performance while your website changes underneath it. You need it if you’re:

  • Moving CMS or replatforming
  • Rebranding or changing domains
  • Restructuring URLs or site architecture
  • Merging or splitting websites
  • Moving HTTP to HTTPS, or subdomain to subfolder
  • Finally tidying up a site that’s grown messy over the years
  • Already mid-build, with nobody yet thinking about search visibility

Whatever the trigger, the principle doesn’t change: search engines need to trust your new site as much as they trusted the old one, and every gap between “old site” and “new site” is a moment where visibility – and revenue – can quietly leak away.

The earlier our technical SEO team is involved, the more we shape the plan instead of firefighting what’s already built. But if you’re reading this mid-project: it’s not too late. There’s still time to get the fundamentals right before launch, and that time gets more valuable the closer you get to go-live.

Our process

Successful website migrations aren’t left to chance. Here’s how we protect your visibility before, during and after launch.

01
Benchmark

Before anything changes, we benchmark your current rankings, traffic, technical health and visibility. This often builds on a wider SEO audit, giving us a clear picture of what’s worth protecting before launch and a pre-migration benchmark, so you know exactly what success looks like after launch

02
Build the migration plan

We build a complete redirect map between old and new URLs, alongside a developer-ready migration checklist covering everything from canonical tags to XML sitemaps to structured data, giving your team (or ours) exactly what they need to build against.

03
Test before launch

We crawl and test the new site on staging before it goes live, checking redirects, indexation settings and technical health, so you get full pre-launch sign-off and problems are caught before launch, not after.

04
Launch together

We’re on hand during go-live – or we might be putting it live ourselves – to check redirects are firing correctly, the site is crawlable, and nothing unexpected has slipped through.

05
Monitor & recover

In the weeks after launch, we track indexation, visibility across traditional and AI search and traffic volume against your benchmark, with ongoing monitoring and fast action on anything that dips, rather than waiting for a quarterly report to notice.

FAQs

We're already mid-build, is it too late to bring you in?

No. An earlier start gives us more control, but there’s still real value in reviewing the URL structure and redirect plan before launch, rather than after something’s gone wrong.

How much does SEO migration support cost?

It depends on the size and complexity of what’s moving – which is exactly why we don’t quote a single flat fee. A 50-page brochure site migrating CMS is a different job to a 5,000-page site restructuring its entire URL architecture, and pricing that identically would mean either overcharging simple projects or under-resourcing complex ones. Once we know your page count, current CMS, target platform and go-live date, we can give you a fixed quote.

What's the biggest risk during a website migration?

Missed or incorrect redirects. It’s the single most common cause of lost rankings after a migration, and one of the easiest things to get wrong without a proper mapping process.

How long does it take to recover rankings after a migration?

There’s no fixed timeline, but the difference between a good and bad migration is stark. A well-planned migration usually sees short-term fluctuation while search engines recrawl and reprocess the new structure, with visibility recovering over the following weeks. A poorly planned one can take months to recover – and if key signals are lost permanently, rankings sometimes don’t fully return without years of work. That’s why we weight post-launch monitoring as heavily as pre-launch planning: catching issues in week one, not quarter two.

Can you work alongside our existing web developers or agency?

Yes. We regularly work alongside development and marketing teams, providing the SEO requirements, redirect maps and testing while they handle the build.

Can you recover a migration that's already gone wrong?

Yes, and this is often where we do our most valuable work. We audit what changed, identify exactly where rankings, traffic or indexation broke down, and build a recovery plan to fix it. Recovery is rarely instant, but with the right diagnosis, most lost visibility can be rebuilt.
