STEP BY STEP
SEO-safe migration timeline

Before launch
- Crawl the old site and export all URLs
- Pull traffic and backlink data per URL
- Map old URLs to the closest new equivalent
- Keep titles, content and internal links where possible
- Test redirects on staging
Launch day
Deploy 301 redirects, submit new sitemaps, check robots.txt and noindex tags, and verify analytics and tracking immediately.
After launch
Crawl the live site, fix 404s, monitor Search Console coverage and rankings daily, and keep old sitemaps for a few weeks to speed up re-crawling.
Common mistakes to avoid
