A migration can undo years of search progress overnight if it’s handled carelessly, which is why Corndel moved its whole CMS with us and lost zero authority.

What we build

The work that gets a migration through intact

Pre-migration audit

Before anything changes we benchmark your current performance and flag what needs attention, so there is a baseline to hold the new site against.

Redirect mapping

A complete 301 map that preserves link equity, sends users to the right content and avoids crawl errors. Every valuable page points at a relevant new URL.

Content and structure planning

We audit what you have and restructure the site around users and search engines together, so you know what to keep, improve, combine or retire.

On-page SEO and metadata

Titles, meta descriptions, heading structure, canonicals, schema, noindex rules and image data carried across and refined, with room for the site to grow.

Pre-launch QA

Full checks before you go live. Redirect and crawl testing, link checking, indexability and robots, schema validation, and UX and mobile performance.

Post-launch monitoring

Keyword and traffic trends, indexation and crawl data, redirects behaving as expected, and the user journeys and conversion paths that follow.

Years of work can vanish on launch night. The fix is mapping redirects and structure before you go live, not after.

A migration is an opportunity, not just a risk

A migration is an opportunity

Most migrations are treated as something to survive. Done properly it is the cleanest opportunity you will get to fix a structure that has been holding the site back for years.

Consolidate while you move

We use the move to consolidate thin and competing pages, correct an information architecture that grew by accident, and set crawl and indexation rules from day one rather than retrofitting them later.

Recover, then go past it

The result is a site that recovers quickly and then goes past where it was, rather than one that spends six months getting back to level.

Why trust us with it

What we have actually migrated

Corndel’s move to a new CMS

Corndel moved their entire site to a new CMS while we ran the SEO side. Domain authority held at 40 through the switch and has since risen to 50. Referring domains went from 328 to 324, which is noise rather than loss. The migration also surfaced more than 2,000 monthly click opportunities the old structure had been hiding.

AlumierMD across three territories

AlumierMD was harder, because it was three territories at once. We kept site health above 95 through the move, organic clicks rose 7.5%, and click-through rate rose 25.8% as the new templates started earning better listings. The US and Canadian domains held their authority alongside the UK one.

One five stage plan

Both of those ran to the same five stage plan, and the order matters more than any single step. Crawl and record the old site before anything changes, because you cannot prove what you preserved if you never measured it. Map every URL, including the ones nobody remembers. Build the redirects as a spreadsheet you can test rather than a rule in a config file. Launch and monitor either side of the switch. Then spend the following month recovering the things that always slip, because something always slips.

Where bad migrations go wrong

The failure mode we see most often in sites that come to us after a bad migration is not a missing redirect. It is a redirect chain three or four hops long, pointing at a page that no longer covers the topic the original page ranked for. The link still resolves, so nobody notices for a quarter, and by then the rankings are gone.

No promise of zero movement

What we will not do is promise zero movement. Traffic dips of a few weeks are normal on a large replatform, and an agency guaranteeing otherwise is either not being straight with you or plans to blame the dev team. What we commit to is the plan, the monitoring and the recovery work, and a number you can check against the one we recorded before the switch.

Two things to ask first

If you are choosing an SEO migration agency, ask for two things before you sign anything: the before crawl from a migration they ran, and the traffic graph either side of the switch. Any agency that has done this properly keeps both, because they are the only evidence that the work held. If they cannot produce them, you are paying for a redirect spreadsheet and a hope.

Frequently asked questions

What is a website migration?

Any major change to your site, such as a new platform, domain, structure or design. Without SEO guidance, migrations can cost you traffic and rankings.

Will a migration impact my search performance?

It can, especially if redirects are missed or SEO is left out of the plan. That is why we take a proactive approach to safeguard your rankings before anything moves.

How long does a website migration take?

Most take between four and twelve weeks depending on complexity. You get a clear plan and schedule from day one.

What platforms do you work with?

We have delivered migrations on Shopify, WordPress, Webflow, Magento and more. The approach is tailored to your CMS and your objectives.

Can you help if the migration has already started?

Yes. If you are mid project, or have launched and noticed problems, we can audit the setup, find what went wrong and get things back on track.

How much does an SEO migration cost?

We scope every retainer to your site, and a migration usually weights the first quarter heavier before settling. The variable is the size of the URL map and how much of the old site nobody can account for. We scope after the first crawl rather than before it, because guessing at the number of redirects is how migrations go over.

We’ll look at what you rank for, where competitors are winning instead, and what is worth fixing first. No charge, and the findings are yours either way.
