Pre-Migration SEO Audit Checklist

The Foundation of a Successful Migration

Before touching a single file, you need complete visibility into your current site’s SEO health. This audit becomes your migration roadmap and your insurance policy.

Technical SEO Audit

Content Audit

Backlink Audit

Important: Export all data into a master spreadsheet. This is your migration bible.

URL Mapping and Redirect Strategy

The Most Critical Migration Step

URL mapping is the process of matching every URL on your old site to a corresponding URL on your new site. Get this wrong, and you lose rankings. Get this right, and you preserve 95%+ of your SEO value.

The URL Mapping Process

1. Export all URLs from the old site (Screaming Frog, CMS export, sitemap).
2. Categorize URLs by type (homepage, category, product, blog, landing page).
3. Map each URL to its new equivalent on the target platform.
4. Identify orphaned URLs (old pages with no new equivalent).
5. Plan redirects (301 for preserved pages, 410 for removed pages).

URL Mapping Template

Redirect Best Practices

1. Use 301 Redirects (Permanent)

• Passes 90–99% of link equity to the new URL
• Signals to Google that the move is permanent
• Updates index over time

2. Avoid Redirect Chains

• Bad: /old-page → /intermediate-page → /new-page
• Good: /old-page → /new-page (direct)
• Maximum chain length: 2 hops

3. Implement Redirects Before Launch

• Test all redirects in staging environment
• Verify with curl or redirect checker tools
• Ensure no redirect loops

4. Preserve URL Parameters

• If old URLs had tracking parameters, ensure new redirects preserve them
• Example: /product?id=123 → /products/item-123?utm_source=old

5. Handle Edge Cases

• Trailing slashes (/page vs. /page/)
• Case sensitivity (/Page vs. /page)
• WWW vs. non-WWW
• HTTP vs. HTTPS

Redirect Implementation by Platform

WordPress (Redirection Plugin)

Source: /old-page
Target: /new-page
Type: 301

Apache (.htaccess)

Redirect 301 /old-page https://www.example.com/new-page

Nginx

location /old-page {
	return 301 https://www.example.com/new-page;
}

Shopify

• Use Shopify’s URL redirects in admin
• Bulk upload via CSV for large migrations

Cloudflare

• Use Page Rules for redirects
• Bulk redirect lists for large-scale migrations

Content Transfer: What Gets Lost and How to Prevent It

The Content Migration Checklist

Content is more than text. It’s structure, metadata, media, and relationships. Here’s what to transfer and what commonly gets lost:

Must Transfer

Common Content Loss Scenarios

1. Image URL Breakage

• Old images referenced by absolute URLs
• New site has different media path
• Fix: Export all images, upload to new site, update all image URLs in content

2. Shortcode Breakage

• WordPress shortcodes such as

  

  

  
  
  and contact-form don’t exist on new platforms
• Fix: Convert shortcodes to HTML before migration, or recreate functionality

3. Embed Code Issues

• Custom embeds, iframes, and scripts may not work on new platforms
• Fix: Test all embeds in staging, update or replace as needed

4. Formatting Loss

• WYSIWYG editor differences cause formatting issues
• Fix: Clean HTML export, manual review of top pages

5. Menu/Navigation Loss

• Menu structures don’t transfer automatically
• Fix: Rebuild menus manually, ensure internal links are updated
