Agencies routinely declare a migration project done the moment the new site goes live, even when it quietly costs the client 10-30% of revenue for months afterward. Most ranking damage is completely preventable with proper pre-launch planning.
Why Migrations Lose Search Rankings
- Unmapped URL structure changes: Wix, Shopify, Squarespace, and WordPress all generate URLs differently. When old URLs disappear without 301 redirects, search engine rankings evaporate.
- Missing 301 redirects: A 301 redirect informs search engines that a page has permanently moved, preserving existing domain authority and backlinks.
- Lost metadata & canonical tags: Title tags, meta descriptions, schema markup, and canonical tags must be migrated deliberately.
- Core Web Vitals & technical accessibility: Search bots and visitors must load the new site cleanly without performance bottlenecks.
Migration Risk by Platform
| Source Platform | Primary SEO Risk | Key Action Required |
|---|---|---|
| Wix | Absolute pixel layout & Wix URL patterns | Complete URL remapping & mobile layout rebuild |
| Squarespace | Nested blog & collection URL paths | URL mapping, metadata & schema recreation (read Squarespace to WordPress migration) |
| Shopify | Product & collection URL structures | 301 redirects for every SKU, collection & variant |
| Existing WP Host | Lower risk overall | Email continuity (MX/SPF/DKIM) & staging tests |
Step-by-Step SEO Migration Checklist
- Document baseline SEO: Export top organic landing pages, keyword rankings, and backlink profiles from Google Search Console.
- Crawl existing site URLs: Map all live URLs before making server changes.
- Build a 301 redirect map: Map every old URL to its exact new WordPress counterpart.
- Migrate metadata: Transfer title tags, meta descriptions, and schema markup intact.
- Handle DNS & email records: Verify MX, SPF, and DKIM settings during DNS cutover.
- Launch with 301 redirects live from Day 1.
- Monitor Search Console daily for 30-60 days: Audit crawl errors, index status, and traffic recovery.
What "Success" Looks Like
A temporary 10-15% traffic fluctuation lasting 2-3 weeks is normal while search engines recrawl your structure. If traffic declines worsen past 30-60 days, technical redirect gaps or unmapped canonicals are the root cause.
