What is a Website Migration?

A website migration refers to any major change to a website’s structure, domain, platform, or content that affects search engine visibility. When done correctly, a migration preserves search rankings, redirects users properly, and ensures SEO continuity.

Common migration types include:

• Domain-to-domain migration (e.g., oldsite.com → newsite.com)

• URL restructuring (changing the site’s URL structure)

• CMS migration (e.g., moving from WordPress to Webflow)

• HTTPS migration (switching from HTTP to HTTPS)

• Mobile-first redesigns

• Merging multiple sites into one

Each type has unique challenges, and without a well-executed migration plan, rankings, traffic, and UX can suffer.

Why Do Websites Migrate?

Companies undergo website migrations for a variety of reasons, including:

🔹 Branding & Domain Rebranding – Changing domain names due to company rebranding. 🔹 Merging Websites – Consolidating multiple sites into one. 🔹 CMS Upgrades – Switching to a new content management system (CMS). 🔹 SEO Improvements – Cleaning up outdated URLs and improving site structure. 🔹 Security & HTTPS Migration – Moving from HTTP to HTTPS for better security. 🔹 Mobile Optimization – Restructuring a site for mobile-first indexing.

Regardless of the reason, a clear migration strategy is necessary to preserve your SEO performance and maintain rankings.

Common SEO Risks in Website Migration

🚨 1. Losing Page Authority Due to Broken Redirects

If 301 redirects are not implemented correctly, search engines won’t pass ranking authority to new URLs, leading to a drop in rankings.

✅ Solution: Ensure a one-to-one 301 redirect from old pages to their relevant new versions.

🚨 2. Indexation Issues

Search engines may struggle to index the new site if there’s poor internal linking, missing sitemaps, or conflicting robots.txt rules.

✅ Solution: Submit a new sitemap in Google Search Console and verify that all pages are crawlable.

🚨 3. Traffic Drops Post-Migration

A sudden traffic drop is common after migrations if Google struggles to recognize the new site structure.

✅ Solution: Monitor Google Search Console errors, fix missing redirects, and track organic performance daily.

🚨 4. Poor User Experience (UX) & Broken Links

If internal links and navigation aren’t updated, users will encounter 404 errors and broken pages.

✅ Solution: Audit all links and update navigation to reflect the new site structure.
