A website migration is one of the highest-risk technical SEO projects a business can undertake, and when handled incorrectly, the damage is immediate and measurable.
A website migration can unlock faster performance, stronger branding, and a better user experience, but a single misstep can wipe out years of organic growth overnight. Rankings drop.
Traffic disappears. Leads dry up. And recovery becomes slow and expensive.
That is why SEO must sit at the centre of every migration decision.
Whether you are redesigning your website, changing your CMS, moving to a new domain, or restructuring URLs, this SEO website migration checklist will help you protect rankings, preserve authority, and build a stronger foundation for future growth.
A successful migration requires detailed URL mapping, 301 redirect logic, crawl budget management, indexation control, canonical validation, internal linking preservation, and server-side performance optimisation.
