Technical Definition
Site migration is any significant change to a website: domain change, platform change, URL restructure, HTTPS migration, or major redesign. High-risk for SEO if poorly executed. Requirements: comprehensive URL mapping, proper 301 redirects, updated internal links, new sitemaps, Search Console verification, monitoring. Traffic typically dips during migration before recovering.
Simple Explanation (ELI13)
Site migration is making a big change to your website, like moving to a new domain name, changing your platform, or redesigning everything. It's risky for SEO because if you don't do it right, you can lose your rankings. The key is setting up redirects from old URLs to new URLs so Google knows where everything moved.
