Website migration SEO checklist

Pre-launch and post-launch SEO checks when replatforming—URLs, redirects, parity, and Search Console.

Use this with website migration services and methodology parity practices.

Before cutover

Crawl legacy URLs; export status codes and canonicals
Map 1:1 redirects (301) for indexable pages; document intentional removals (410)
Freeze new legacy content or sync process defined
Match title/meta on top-traffic URLs or improve with intent, not churn
Internal link graph plan for new templates
Staging noindex verified

Launch day

Lower DNS/TTL; deploy redirects at edge first
Smoke-test top 50 URLs (status, canonical, hreflang if used)
Submit sitemap in Search Console property
Monitor 404/5xx logs in real time

After launch (30–90 days)

Compare GSC coverage and query groups week over week
Fix redirect chains and parameter duplication
Reconcile structured data on templates
Keep content parity for mirrored child pages per network rules

We do not promise ranking preservation—only auditable technical parity and documented decisions.
