Our SEO team specialises in website migrations

Based in the heart of London, we are a digital agency with years of experience running and overseeing complex SEO migration projects.

A website migration can fail for many reasons – missed redirects, incomplete sitemaps, or overlooked technical checks – all of which can cause sudden ranking drops and traffic loss. Our SEO team works with you to mitigate these risks, ensuring that whether you’re redesigning, restructuring, or managing a SEO domain migration, your visibility in search results remains protected.

We’ve delivered successful migrations for businesses across industries, often collaborating with multiple Finn Partners teams. With a full-service approach that combines website migration, SEO services, and web design and development expertise, we can manage the entire process end-to-end – planning, building, and optimising your new site for long-term performance.

Our website migration SEO services

The support we provide depends on the complexity of the migration and your budget, but every project follows a structured process. Our SEO migration service is broken down into three key phases:

PRE-MIGRATION SEO
This critical stage happens before launch and is where SEO input has the biggest impact. We conduct a full audit, map redirects, prepare sitemaps, and optimise the new site’s structure. Whether it’s a redesign, a CMS migration SEO project, or a full SEO domain migration, this preparation safeguards your visibility from day one.

MIGRATION DAY
On launch day, our team runs through a priority checklist of technical factors to protect site health. We ensure redirects are working, no crawling or indexing blockers exist, and all essential elements are aligned to avoid search performance disruption.

POST MIGRATION SEO
The 4–6 weeks after launch are crucial. During this time we closely monitor traffic, rankings, and crawl data to track recovery and performance. Any issues are flagged and resolved immediately, giving your business confidence that organic growth will remain stable.

No two migrations are the same. Our website migration SEO services are completely bespoke, tailored to the scale and complexity of your project. To discuss your requirements and receive a tailored plan, get in touch with our team.

Full Website Migration Support

Managing multiple teams during a migration can be overwhelming. We offer more than just SEO migration services — our specialists can oversee the entire project with a tailored solution to meet your needs.

As part of a full migration, we combine SEO with web design, development, and hosting, and can even run paid media campaigns post-launch to offset any initial traffic dips.

Whether you need support with a SEO domain migration, CMS migration SEO, or a full redesign, your dedicated account manager will be your single point of contact. They’ll coordinate our in-house teams, keep communication seamless, and ensure every aspect of the project is aligned.

Typical migrations we support include:

• Domain migrations – rebranding or moving to a new domain
• Subdomain migrations – consolidating content into subfolders
• CMS migrations – upgrading or changing your content management system
• Protocol migrations – moving from HTTP to HTTPS
• Structural migrations – updating architecture, URL structure, and navigation
• Content migrations – consolidating, updating, or removing large volumes of content
• Design migrations – modernising layouts and improving user experience

With our website migration SEO services, you can be confident that every stage of the process is covered, risks are minimised, and your search visibility is protected.

SEO migration FAQs

• Why is SEO so important during a website migration?

  SEO is often the most overlooked part of a migration — but also the most critical. Without a structured SEO migration strategy, even small mistakes like missing redirects or poorly planned URL structures can result in huge traffic and revenue losses. Incorporating site migration and SEO from the outset ensures your rankings, visibility, and organic performance are protected.

• What are the main risks of a website migration?

  The biggest risks include traffic loss, broken redirects, indexation errors, duplicate content, and lost backlinks. These issues are common when SEO is left until the end of the process. By working with a specialist SEO migration agency, you can avoid these pitfalls. Our proven website migration SEO services safeguard search equity while ensuring the new site is structured for long-term growth.

• How long does an SEO migration take?

  The timeline depends on the scale and complexity of the project. A simple protocol migration may take a few weeks, while a full CMS migration SEO or multi-domain consolidation can span several months. We typically recommend starting SEO involvement as early as possible, so technical audits, URL mapping, and staging reviews are completed well ahead of launch.

• Can a website migration improve SEO performance?

  Yes. While the main goal of SEO migration services is to protect your existing visibility, migration also presents an opportunity to enhance site structure, content, and technical SEO. For example, a SEO domain migration or platform rebuild can consolidate content, improve speed, and modernise UX – leading to long-term traffic growth beyond your pre-migration performance.

• How much does an SEO migration cost?

  Costs vary depending on complexity. A smaller migration, such as moving to HTTPS, is more straightforward than a full CMS migration SEO project or international consolidation. For enterprises, the investment is small compared to the potential losses from a poorly executed migration. Our SEO migration consultants scope each project individually, providing a transparent, tailored cost based on the risks and requirements.

• What’s the difference between domain, CMS, and design migrations?

  • SEO domain migration: moving to a new domain (e.g. rebranding).

  • CMS migration SEO: switching platforms (e.g. WordPress to Shopify).

  • Design migration: updating the site’s look and feel.

    Each has different SEO implications, from redirect mapping to crawl testing. Our SEO migration services cover all types, ensuring search equity is preserved.

• Do you provide post-migration SEO support?

  Yes. Our website migration SEO services extend well beyond launch day. We monitor performance for 4–6 weeks post-migration, tracking keyword rankings, organic traffic, and crawl data. Any issues are resolved immediately, giving you confidence that the new site is stable and optimised for growth.

• Why should larger businesses use an SEO migration agency?

  Enterprises face unique challenges: multiple domains, large teams, complex site structures, and significant revenue tied to organic traffic. A specialist SEO migration agency brings the experience, tools, and processes to manage these risks. Our consultants work alongside your developers, designers, and marketers to deliver a seamless transition that safeguards visibility at scale.

• How do you handle international website migrations?

  International projects are especially complex because they often involve multiple languages, hreflang tags, and country-specific domains or subfolders. A poorly executed migration can damage visibility in several markets at once. Our SEO migration consultants apply a tailored SEO migration strategy that includes international keyword mapping, hreflang validation, and market-specific checks. This ensures your global visibility remains intact during any site migration and SEO project.

• Do you use AI or automation in SEO migration audits?

  Yes – automation helps us work more efficiently on large-scale migrations. We use AI-driven tools for log file analysis, crawl simulations, and error detection to spot issues faster across enterprise websites. However, every recommendation is overseen by an experienced search engine optimisation consultant, because migrations require strategic judgement as well as data. By combining automation with human expertise, our website migration SEO services deliver accuracy, speed, and peace of mind.

• What is the process to ensure my rankings are not impacted by the site migration?

  Unfortunately, with a migration you will always see fluctuations in your rankings as search engines crawl the changes and get to know your new site. However, we do take steps to protect your priority keyword rankings.

  We take note of what your top keywords are, and the pages that ranks for that keyword in the search results. We then work with you to develop a content plan that makes sure the content that is earning those rankings is not lost in the migration. This might involve telling pages, which you may have wanted to remove, need to stay. It may involve identifying where content across pages needs to be consolidated onto one.

  We appreciate clients often want to trim their content as part of a migration. We’ll work with you to make sure your trimmed content is content your organic performance can easily part with.
