This document outlines best practices for conducting a website redesign from an SEO perspective. It recommends developing the new site separately, blocking search engines from indexing it, and setting up 301 redirects for all changed URLs. On launch day, the redirects should go live and restrictions removed. Post-launch, analytics should be closely monitored for any issues with traffic, rankings or indexing. The key takeaways are to avoid confusing search engines, use 301 redirects properly, and watch analytics carefully after migrating to the new site.
