1. Introduction
If you’re planning to redesign your website, switch hosting, upgrade your CMS, or move to a new domain, you need a well-planned SEO Website Migration strategy. From my experience working with Australian brands—local businesses, national e-commerce stores, and enterprise sites—SEO Website Migration is one of the most delicate processes in digital marketing. Done correctly, your rankings stay protected. Done poorly, and your traffic can disappear overnight.
2. Featured Definition (40–55 words)
SEO Website Migration is the process of moving a website to a new platform, design, structure, domain, or hosting environment while preserving existing SEO value. It involves technical auditing, redirects, content mapping, testing, and post-launch monitoring to ensure rankings, traffic, and visibility remain stable throughout the transition.
3. Why SEO Website Migration Matters
Australia’s online landscape is competitive, and users expect fast, modern, mobile-friendly websites. Migrations are often necessary for:
-
website redesigns
-
CMS upgrades
-
domain changes
-
HTTPS upgrades
-
server migrations
-
structural improvements
-
mobile-first rebuilds
However, without SEO planning, migrations can lead to:
-
ranking drops
-
major traffic losses
-
broken pages
-
lost backlinks
-
indexing issues
-
incorrect redirects
-
damaged conversions
According to Search Engine Journal (source), poor migrations are one of the top causes of sudden organic traffic declines. The ACMA also highlights growing Australian dependence on online search, making migration stability critical.
4. Types of Website Migrations
Understanding your migration type helps set the right SEO plan.
1. Domain Migration
example: yoursite.com.au → yourbrand.com.au
2. Platform/CMS Migration
example: WordPress → Shopify
3. Site Redesign
New layout, templates, branding.
4. URL Structure Migration
Changing URL formats or directories.
5. Protocol Migration
http → https upgrades.
6. Mobile Migration
Switching to responsive or mobile-first design.
7. Hosting/Server Migration

8. Content Migration
Restructuring or replacing content.
Each requires specific technical checks.
5. SEO Website Migration vs Standard Migration (Comparison Table)
