A migration — new domain, new CMS, or restructured URLs — is one of the highest-risk moments in a site's SEO life if it isn't planned carefully.
Map Every URL Before You Move
A complete redirect map from old to new URLs, tested before launch, is the single biggest factor in preserving rankings through a migration.
Preserve Content, Not Just URLs
Rewriting content during a migration at the same time you change the URL structure makes it much harder to isolate what caused a ranking change.
Monitor Closely After Launch
Watch indexing status, crawl errors, and rankings daily for the first few weeks so issues get caught while they're still easy to fix.
Next step: Use the Google Index Checker to confirm your new URLs are actually getting indexed after launch.
