A website change is also a change in signals for search engines

A new website can improve design, technology and conversion, but it can also interrupt years of organic work when URLs, content, links or technical rules that search engines already know disappear. An SEO migration transfers the value of the existing site to the new environment so that a change does not become an avoidable loss of visibility.

We start with an inventory of pages, queries, links, content and assets that matter. We identify URLs with traffic, commercial value or authority, the sections that must be retained and the architecture changes that are actually needed. This creates a mapping between the current and future site based on purpose, not just URL names.

The work is coordinated with design, development, content and business teams. SEO should be involved before the structure is final so that hierarchy, templates, metadata, internal links, filters and requirements are resolved before launch.

Redirects, testing and monitoring for a controlled launch

Redirects are central to a migration, but they need precise logic. Every valuable URL should point to the closest destination that preserves user intent; entire sections should not be sent to the homepage and redirect chains should be avoided. We also review canonicals, sitemaps, robots directives, structured data, languages, internal links and server responses.

Before launch, we validate the staging environment: navigation, intended indexability, metadata, templates, content, URLs, forms, analytics and key journeys. After launch, we crawl the site, review errors, monitor indexation and compare priority pages against the initial inventory.

A migration does not end on release day. Follow-up confirms that search engines process the change correctly, identifies discrepancies and lets the team resolve issues before they affect organic performance.

Inventory and URL mapping

We collect URLs, traffic, links, content, templates and technical elements. We decide what to retain, improve or retire, and define specific destinations for pages whose URL or role changes.

SEO requirements and pre-launch validation

We provide requirements for architecture, redirects, indexation, canonicals, sitemaps, metadata, structured data, measurement and content, then test the new environment before launch.

Launch, crawling and stabilisation

We check responses, redirects, accessibility, links, sitemaps and indexation signals from day one, then monitor traffic and priority URLs in the weeks after launch.

After launch, we compare signals against the previous situation and maintain a clear list of outstanding checks. This makes it easier to identify genuine deviations and address them with defined ownership.

We support coordination with clear checkpoints. Redirects, content and technical requirements remain consistent even when new needs or changes appear during the project.

Frequently asked questions

WE ANSWER
YOUR QUESTIONS

Key details on methodology, investment and digital project development.

What is an SEO migration?

It is the analysis, decision-making and validation process that protects organic visibility when a website changes domain, technology, structure, design, URLs, content or platform.

When is an SEO migration needed?

For significant changes such as a redesign, CMS or domain change, site consolidation, new architecture, international expansion or large-scale URL and content changes.

Are 301 redirects enough?

They are essential, but not enough on their own. Every valuable URL needs a useful equivalent destination, while internal links, canonicals, indexation, sitemaps, content, structured data and performance must also be reviewed.

Will an SEO migration cause traffic loss?

Careful planning reduces risk, but large changes can still cause temporary fluctuations. Pre-launch work, staging validation and post-launch monitoring allow issues to be found and limited quickly.

What happens to old pages with no equivalent?

We assess their value, traffic, links and relationship to the new site. Some can redirect to the closest alternative; others need controlled retirement. We do not send many unrelated URLs to one generic page.

Can you be involved before the new website is designed?

Yes, and that is the best time. Early SEO involvement avoids costly later decisions such as unnecessary URL changes, incomplete templates, uncontrolled indexable filters or valuable content disappearing in a redesign.

How long does an SEO migration take?

It depends on URL count, technical complexity, integrations and scale of change. The process includes inventory, planning, pre-launch validation, launch and follow-up.

How is a migration validated after launch?

We review responses and redirect chains, crawling, indexation, sitemaps, canonicals, internal links, errors, coverage and the evolution of priority pages and queries.
