SEO Website Migration Services That Protect Your Rankings
A migration is the single highest-risk event a website can undertake. Done properly you keep everything you have built. Done badly you can lose years of authority in a weekend, and sometimes it never comes back.
Call Us Before, Not After
Most migration enquiries we receive are recovery jobs. Someone launched, traffic collapsed, and now we are reverse engineering what broke. Involving SEO before the architecture is final costs a fraction of fixing it afterwards.
What Counts as a Migration?
More than people expect. Any change that alters URLs, site structure, hosting or how content is served carries migration risk, and several of these are routinely done without anyone consulting SEO at all.
Domain change
Rebrand, acquisition or consolidating multiple domains into one. The highest-risk category, because every single URL changes at once.
Platform replatform
WordPress to Shopify, Magento to headless, custom to a CMS. URL structures, rendering and templates all change together.
URL restructure
Changing your permalink pattern or reorganising site architecture. Looks harmless in a CMS setting, breaks every link pointing at you.
Redesign
New design on the same URLs still changes content, internal links, heading structure and page speed. Frequently underestimated.
HTTP to HTTPS
Simpler than it used to be, still capable of producing redirect chains and mixed content issues that suppress rankings.
Internationalisation
Adding country subfolders or subdomains, introducing hreflang, or splitting a single site into regional versions.
What Actually Goes Wrong in a Migration
These are the failure modes we see repeatedly in recovery work. Every one is preventable, and every one was preventable at a fraction of the cost of fixing it afterwards.
The most common cause of catastrophic loss. Redirects get mapped in the final week, blanket-redirected to the homepage, or missed entirely for older URLs that still hold links.
By the time anyone asks, the URL structure is decided, the templates are built and changing them means rework nobody has budget for. The damage is designed in.
Staging gets crawled and creates duplicate content, or the noindex tag protecting staging ships to production and quietly deindexes the entire site.
Pages that were ranking get cut because nobody checked performance before deciding what to keep. Design decides the sitemap instead of data.
A move to a JavaScript framework without server-side rendering. The site looks perfect in a browser and is nearly empty to a crawler.
The team celebrates, moves on, and nobody notices the coverage errors accumulating in Search Console until the quarterly report shows a cliff.
Why recovery costs so much more than prevention
When a migration goes wrong, you are not just fixing the technical fault. You are waiting for Google to recrawl and re-evaluate a site it has just been told changed dramatically, while your competitors absorb the traffic you lost.
Some rankings return within weeks once redirects are corrected. Some take months. And a proportion of link equity from redirect chains and missed URLs is simply never recovered. That is why we would rather be involved at the planning stage than paid more to fix it later.
The pattern we see in recovery work
That last one makes diagnosis far harder. Always keep a full crawl of the old site.
Planning a migration this year?
Talk to us before the architecture is final. A short planning conversation now prevents the kind of loss that takes six months and a great deal of money to undo.
Our Migration Process
Five phases. The first two happen before a single line of the new site is built, which is the entire point.
Planning
Baseline and architecture review
Full crawl of the existing site preserved as a reference, ranking and traffic baseline captured, backlink inventory mapped, and top performing URLs identified. We review the proposed architecture before it is locked and flag anything that will cost you rankings.
Mapping
Redirect map, URL by URL
Every existing URL mapped to its destination. No blanket homepage redirects, no missed legacy URLs that still hold links, no chains. This is the single most important deliverable in any migration and it is where most projects cut corners.
Pre-launch
Staging crawl and sign-off
Full crawl of staging, rendering tested across every template, redirects verified in bulk, schema validated, Core Web Vitals measured, and a written go or no-go recommendation. We will tell you to delay a launch if it is not ready.
Launch
Launch day monitoring
Redirects verified live, robots.txt and noindex checked immediately, sitemaps submitted, Search Console configured, and rapid crawl to catch anything the staging environment did not reveal.
Recovery
Post-launch monitoring, 90 days
Daily then weekly monitoring of indexation, rankings, traffic and coverage errors, compared against the pre-launch baseline. Issues get fixed while they are small rather than discovered in a quarterly report.
Our Migration Services
Scoped to the type and scale of the change. A permalink restructure and a full replatform need very different amounts of work.
Pre-migration audit
Full baseline crawl, ranking and traffic snapshot, backlink inventory, and identification of the pages you cannot afford to lose.
Redirect mapping
Every URL mapped one to one, including legacy URLs that still hold links. Delivered as a file your developers can implement directly.
Architecture consulting
Reviewing the proposed URL structure, navigation and templates before they are built, when changes are still cheap.
Staging testing and sign-off
Full crawl, rendering tests, redirect verification, schema validation and a written go or no-go recommendation.
Launch day support
Live verification of redirects, robots.txt, noindex tags, sitemaps and Search Console configuration while the change is still reversible.
90 day monitoring
Automated indexation, ranking and coverage monitoring compared against baseline, so problems surface in days rather than months.
International migrations
Hreflang implementation, regional splits, and consolidating or separating country versions without losing market visibility.
Domain consolidation
Merging multiple domains into one while preserving the authority each had built, including microsites and acquired properties.
Migration recovery
Diagnosis and repair when a migration has already gone wrong. Covered in detail below.
Migration Recovery
If you have already launched and traffic has dropped, the situation is usually recoverable, and the first job is diagnosis rather than guessing.
We compare the current site against archived crawls and Search Console history to find what actually changed. Most losses trace to a small number of causes: missing or chained redirects, an accidental noindex, a rendering change, canonical conflicts, or valuable content that was silently dropped.
Speed matters here. The longer incorrect signals stay live, the longer recovery takes. If you launched recently and something looks wrong, do not wait for the next reporting cycle to confirm it.
Recovery diagnosis covers
Traffic dropped after a launch?
A free diagnostic identifying what changed and what is recoverable. The sooner incorrect signals are corrected, the faster rankings return.
Real Results: 100% #1 Rankings Across an Entire Service Area
Part of this engagement was a full website rebuild. The migration was planned with redirect mapping and staging verification before launch, which is why rankings grew through the change rather than collapsing.
Water services company, Ohio: from invisible to #1 everywhere
Almost no Google visibility despite years in business and a strong local reputation. We rebuilt the site architecture, deployed schema sitewide, corrected business data across 80+ directories, and built out service and location pages with proper internal linking.
Six months, zero ad spend, #1 at every single tracked point.
Why Choose Hyxil for Your Migration
If staging is not ready, we say so in writing. Launching on a date rather than on readiness is how migrations fail.
WordPress and Next.js in house. We understand what your developers are actually dealing with because we do the same work.
No blanket homepage redirects, no missed legacy URLs. Delivered as a file your team can implement directly.
Automated alerting against your pre-launch baseline, so problems surface in days rather than at the next quarterly review.
Through the HTTPS migration era, mobile-first indexing, the headless transition and countless replatforms.
If it has already gone wrong, we diagnose rather than guess, and we will tell you honestly what is and is not recoverable.
Planned, tested, monitored
The three phases that decide whether a migration protects or destroys what you built.
Migrating soon, or already lost traffic?
Either way, start with a conversation. Planning support costs a fraction of recovery, and recovery is faster the sooner it starts.
