Inventory before you design
Crawl the existing site and export search console data. You need a full list of URLs, their traffic, their backlinks and their rankings. Anything you cannot see, you cannot protect.
Mark each URL as keep, merge, redirect or retire. That single spreadsheet governs the whole migration.
Map every redirect, including the boring ones
Implement one-to-one 301 redirects from old to new URLs, including PDFs and legacy parameters. Avoid redirecting everything to the homepage — it discards relevance and annoys users.
Keep redirects in place indefinitely where possible, and monitor 404s daily for the first month after launch.
Maintain content parity on commercial pages
Redesigns often shorten service pages in the name of minimalism, removing the very text that earned rankings. Keep the substance, improve the structure, and make sure headings still describe the page.
Preserve internal links between service pages and supporting content — navigation changes frequently orphan important pages.
Launch-day and post-launch checks
Validate the new sitemap, confirm indexability, check structured data, and verify analytics and conversion tracking before announcing anything.
Then compare crawl data and rankings weekly for a month. Drops concentrated in one section usually point to a specific missing redirect or template change.
- Sitemap resubmitted and crawl stats healthy
- No noindex directives left in templates
- Conversion tracking firing on every form
- Rankings compared weekly for four weeks
Key takeaways
- Build a URL-level inventory before design starts.
- One-to-one redirects, never blanket homepage redirects.
- Keep content substance on commercial pages.
- Monitor rankings and 404s weekly for a month after launch.
