SEO Migration Services Built to Protect Your Rankings Through Every Website Change
Redesigns, replatforms and domain changes are one of the highest-risk moments for organic traffic. Sentius manages SEO migrations end-to-end, so your rankings survive the move.
What is an SEO Audit?
SEO migration is the process of transferring search engine rankings, authority and indexing signals when a website undergoes a major change — a new site launch, platform migration, restructure, or significant content and design overhaul. Without a proper migration strategy, rankings and traffic built up over years can be lost in days.
Sentius provides SEO migration services for Australian businesses, managing everything from small replatforms to full enterprise-level site launches.

Frequently Asked Questions
Why do I need SEO migration?
When changing your website domain, design, structure, or CMS platform, an SEO migration ensures search engines correctly transfer your established search authority, backlinks, and keyword rankings to the new URLs without losing traffic.
How does website migration affect SEO?
Without proper planning, search engines can view a migrated site as entirely new—resulting in broken links, loss of indexation, and severe traffic drops. Proper migration preserves your historical search equity and guides search crawlers seamlessly through changes.
How do I redirect URLs correctly?
URLs should be mapped on a 1-to-1 basis using permanent 301 redirects, ensuring every legacy page points to its exact equivalent on the new site structure. Avoid redirecting all pages to the homepage, as this degrades keyword relevancy and user experience.
Can I do SEO migration myself, or do I need an agency?
While small sites with minimal page counts can be managed internally, complex platforms benefit significantly from an expert agency. An experienced team audits technical requirements, builds exhaustive redirection matrices, and monitors post-launch health to prevent costly revenue drops.
Will I lose rankings during a redesign?
Some temporary ranking fluctuations are expected as search engines re-crawl and re-index the updated site. With a structured migration process, rankings typically stabilize quickly and often improve as technical debt and site performance are optimized.
