SKILL.md
This skill ensures zero SEO loss during a website migration. It maps old URLs to new ones, generates redirects, preserves metadata, creates sitemaps, and validates structured data.
The user provides: the original site URL, the new site URL (or route structure), and the type of migration (same domain redesign, domain change, or platform migration).
Migration Types
| Type | What changes | SEO risk |
|---|---|---|
| Redesign (same domain) | URLs may change, content restructured | Medium — redirects critical |
| Domain change | Entire domain moves (old.com → new.com) | High — 301s + Search Console change of address |
| Platform migration | CMS/framework change (WordPress → Next.js) | High — URL patterns often change completely |
| HTTPS migration | HTTP → HTTPS | Low — but every URL needs redirect |
