What is an SEO website migration?
An SEO website migration is the process of moving, redesigning, replatforming or restructuring a website while protecting organic rankings, traffic and key landing pages as much as possible.
What is an SEO Website Migration?
An SEO website migration is the work that protects your organic performance when a website changes. That could be a new design, a new CMS, a domain change, a rebrand, a URL restructure, an eCommerce replatform or a move from one website setup to another.
The risky bit is not just launching a new website. The risk comes from changing the things Google already understands about your site. URLs, internal links, content, redirects, canonicals, tracking, templates and page structure can all affect how search engines crawl and rank the site after launch.
My approach is to get involved before the migration happens, benchmark what matters, map the important URLs, work with your developer or agency and check the site properly after launch. The aim is simple: reduce the risk of traffic loss and make sure the new site has the best chance of performing well.
Why SEO Migrations Go Wrong
Most migration problems happen because SEO is brought in too late. By the time the new site is ready to go live, the URL structure may already be built, important content may have been removed and redirects may be treated as a quick launch task rather than a core part of the project.
A website can look better after a redesign and still lose traffic if the SEO details are missed. Important pages can disappear, redirect chains can be created, high performing content can be rewritten too heavily and Google can suddenly see a site that looks very different from the one it previously trusted.
This is why I treat migration work as a risk management project. I look at what already drives traffic and enquiries, what must be protected, what can be improved and what needs to be checked before anything goes live.
My SEO Migration Approach
I keep the process practical and easy to follow. You do not need a 100 page document that nobody uses. You need clear checks, clear ownership and a migration plan that your developer, designer or internal team can actually work with.
01
Performance Benchmarking
I review organic traffic, rankings, key landing pages, conversions and priority pages so we know what needs protecting before the site changes.
02
URL and Redirect Mapping
I map important old URLs to the correct new URLs so users and search engines land in the right place after launch.
03
Content and Metadata Checks
I check that important page content, titles, descriptions, headings and internal links are not lost or weakened during the move.
04
Technical Staging Review
I review the staging site for indexation risks, canonicals, robots rules, sitemaps, speed, mobile issues and crawl problems before launch.
05
Tracking and Search Console
I check analytics, conversion tracking and Google Search Console setup so performance can be monitored properly when the new site goes live.
06
Post Launch Checks
After launch I check redirects, indexing, traffic, crawl errors, forms, tracking and key pages so issues can be found and fixed quickly.
Common Website Migration Mistakes
These are the kinds of issues I look for before, during and after a website migration.
No redirect map
Important URLs removed
Redirect chains
Old URLs returning 404s
Pages accidentally noindexed
Robots.txt blocking staging or live pages
Canonical tags pointing to the wrong URLs
XML sitemap not updated
Internal links still pointing to old URLs
High performing content rewritten too heavily
Tracking not tested before launch
Google Search Console not checked after launch
Images and assets moved without checks
Page templates slower than before
Important metadata missing
DIY Website Migration Checklist
If you are handling a migration yourself, these are the things I would want in place before launch. It is not a replacement for proper migration support, but it will help you avoid some of the most common mistakes.
What to Use and Check
01
Export a full crawl of the current site in Screaming Frog or Sitebulb before anything changes.
02
Export key landing pages, organic traffic and conversions from Google Analytics and Google Search Console.
03
Create a redirect map that matches important old URLs to the most relevant new URLs.
04
Crawl the staging site and check noindex tags, robots.txt, canonicals, headings, metadata and internal links.
05
Prepare a fresh XML sitemap and make sure Search Console is ready for the live site.
06
Test forms, phone tracking, analytics events and conversion tracking before and after launch.
07
After launch, crawl the live site and check redirects, 404s, indexability, canonicals and page speed.
08
Monitor Search Console daily after launch so crawl errors, indexing changes and traffic drops are spotted quickly.
Migration Benefits
Reasons Why You Should Have a Professional Help Migrate Your Website
A migration will always carry some risk, but planning it properly gives you a far better chance of keeping the performance you have already earned.
Protect Organic Traffic
Keep important landing pages, redirects and search signals in mind before the new site goes live.
Cleaner Redirects
Map old URLs to the right new pages so users and search engines are not sent to dead ends.
Fewer Launch Surprises
Catch crawl, indexation, canonical, sitemap and tracking issues before they become live problems.
Better Tracking
Make sure analytics, forms, calls and Search Console are ready to monitor the site after launch.
Lower SEO Risk
Reduce the chance of avoidable ranking drops caused by missed technical or content changes.
A Stronger New Site
Use the migration as a chance to clean up structure, content and technical issues, not just move them over.
SEO Website Migration FAQs
Common questions about protecting SEO performance during a website migration.
When do I need SEO migration support?
You should get SEO involved before a site launch, redesign, rebrand, domain change, CMS change, URL restructure or eCommerce replatform. The earlier SEO is involved, the easier it is to avoid problems.
Can a website migration cause traffic loss?
Yes. If redirects, canonicals, internal links, content, tracking or indexation are handled badly, a migration can lead to ranking drops and traffic loss. The goal is to reduce that risk before launch and monitor closely afterwards.
Do developers handle SEO migrations?
Developers are important, but they are not usually responsible for organic search performance. I can work with your developer or agency to make sure SEO requirements are clear and checked before launch.
What do you check during an SEO migration?
I check current performance, key URLs, redirects, content, metadata, internal links, canonicals, sitemaps, robots rules, tracking, staging site issues and post launch performance.
How much do you charge for SEO migration support?
I charge £40 per hour, so the cost depends on the size of the site, the type of migration and how much support is needed before and after launch.
