How to Protect Your SEO During a Website Migration

Migrating your website — whether to a new domain, CMS, or design — can feel like stepping into unknown territory. It’s an exciting upgrade, but without proper planning, it can also send your hard-earned SEO rankings tumbling.

A poorly executed migration can cause broken links, lost traffic, and even total de-indexing. But with the right strategy, you can transition smoothly and preserve your visibility in search results.

Here’s how to protect your SEO before, during, and after your website migration.

1. What Is a Website Migration — and Why SEO Gets Affected

A website migration happens when major structural or technical changes are made to a site — such as moving to a new domain, redesigning, or switching platforms (like from WordPress to Shopify).

While necessary for growth, migrations often disrupt how search engines understand and crawl your site.

Common causes of SEO loss include:

Changed URL structures without redirects.
Lost meta tags or schema.
Missing sitemaps and canonical tags.
Broken internal links.
Poor testing before going live.

The key to success lies in preparation — treating migration as both a technical project and an SEO strategy.

2. Step 1: Conduct a Pre-Migration SEO Audit

Before making any changes, you need a complete picture of your current site’s performance.

Use tools like Screaming Frog, Ahrefs, or Semrush to crawl your existing site and export:

All active URLs
Meta titles and descriptions
Header tags and content data
Internal and external links
Canonical and sitemap information

Also check your analytics:

Identify top-performing pages by traffic, backlinks, and conversions.
Record keyword rankings for reference after migration.

This audit becomes your SEO blueprint for ensuring nothing valuable gets lost in the move.

3. Step 2: Create a Redirect Map for Every URL

Redirects are the single most important factor in preserving your SEO.

When a URL changes, a 301 redirect ensures both users and search engines reach the new version instead of hitting a 404 error.

Best practices:

Map every old URL to its new destination.
Avoid redirect chains (A → B → C). Instead, redirect directly (A → C).
Redirect obsolete pages to the most relevant alternative — not the homepage.

Example:

Redirect 301 /old-services/seo.html https://newdomain.com/seo-services/

A strong redirect plan preserves your link equity, rankings, and user experience.

4. Step 3: Maintain Metadata and Canonicals

Metadata is often lost in redesigns or CMS migrations. Before launch:

✅ Transfer all meta titles, descriptions, and headings exactly as they were (unless you’re intentionally improving them).

✅ Double-check canonical tags — they should point to live, preferred URLs.

✅ Maintain your robots.txt file and ensure it isn’t blocking key pages.

Losing metadata can instantly reduce your click-through rates and topical relevance — so keep it consistent.

5. Step 4: Generate and Submit a Fresh XML Sitemap

Your sitemap is Google’s map of your website. After the migration:

Create a new XML sitemap reflecting updated URLs.
Submit it to Google Search Console and Bing Webmaster Tools.
Remove any outdated sitemaps from your old domain.

This helps search engines crawl your new structure quickly and accurately.

6. Step 5: Test Before Launch

Never launch without testing — it’s the safety net that prevents disaster.

Use a staging site (not visible to the public) to:

✅ Test all redirects and internal links.

✅ Verify speed, mobile responsiveness, and Core Web Vitals.

✅ Check metadata, schema, and structured data.

✅ Ensure analytics and tracking codes are installed correctly.

By launching from a fully tested environment, you avoid post-launch chaos.

7. Step 6: Go Live Carefully — Then Monitor Everything

When your new site goes live:

Keep your old site active for at least 4–6 weeks so redirects work properly.
Monitor Google Search Console for crawl errors and “404 Not Found” issues.
Track traffic, conversions, and keyword rankings daily for the first few weeks.

Expect small ranking fluctuations — they’re normal. Big drops, however, signal missing redirects or blocked pages that need immediate correction.

8. Step 7: Update Backlinks and External References

Even with redirects in place, it’s best to update important external links manually.

Use Ahrefs or Semrush to find your top referring domains, and contact those webmasters to update the links to your new URLs.

This step helps reinforce authority and speeds up search engine revalidation.

9. Step 8: Communicate Your Move

If your migration includes a domain change, tell both your users and Google.

Use Google Search Console’s “Change of Address” tool.
Post a notice on your homepage or blog announcing the transition.
Update business listings, Google Business Profile, and social media URLs.

Transparency reassures users and helps Google connect your old and new identities seamlessly.

10. Step 9: Track Post-Migration SEO Performance

Continue tracking your performance for 90 days post-launch. Key metrics include:

Indexed pages (via Google Search Console)
Organic traffic volume
Bounce rate and average session duration
Keyword positions for top pages
Conversion rate from organic search

Compare these against your pre-migration baseline to ensure stability or recovery.

11. Step 10: Conduct a Post-Migration SEO Audit

After the first month, do another full crawl using Screaming Frog or Sitebulb.

✅ Check for redirect loops and broken links.

✅ Review canonical tags and sitemap integrity.

✅ Verify mobile performance and Core Web Vitals again.

This final audit ensures all SEO signals are stable — and your new site is fully optimised for long-term success.
