Inventory the existing site
Record every indexable URL, title, description, heading and page that receives meaningful search traffic or links. Export Search Console information before changes.
Preserve URLs or redirect them one-to-one
If a useful page can keep its address, keep it. When a URL must change, use a permanent redirect to the closest equivalent page—not automatically to the homepage.
Carry the important signals forward
Retain accurate service content, local information, internal links, image alt text, canonical tags and structured data. Submit the updated XML sitemap after launch.
Monitor after launch
Check Search Console indexing, redirects, 404s, Core Web Vitals and conversion actions. Keep the old hosting available briefly if practical, and never let the domain registration lapse during a redesign.
