Website redesign and SEO: protect visibility during the change

A practical migration checklist covering URLs, redirects, content, indexing and measurement before and after a website redesign.

1. Record the value of the existing site

Inventory current URLs and identify pages that attract relevant visits or enquiries. Export useful data from Search Console and Analytics before the redesign. Do not rely only on a visual review or memory of which pages perform well.

Include material your sales conversations depend on. A low-traffic page can still be commercially important. Give each page a decision: retain, improve, combine or remove, with a reason attached.

2. Give changed URLs a relevant destination

A new design does not require a new address for every page. Where the page’s purpose remains the same, retaining a useful URL can simplify the change.

Google recommends permanent server-side redirects for permanent URL changes. Map old addresses to relevant new ones rather than sending everything to the homepage. Google’s site-move guide.

3. Review content alongside appearance

A shorter page may be clearer, but it can also lose the answers that attracted visitors. Check whether the service, audience, key questions and next step remain understandable.

Plan internal links deliberately. Guides should lead to relevant services, and services should link to useful explanations. Test each language version independently. A working German page does not establish that its English equivalent is complete.

4. Use a launch acceptance checklist

Test the main journeys from landing page to enquiry or order. Check mobile layouts, navigation, error messages and form confirmation. Review page titles, descriptions, canonical links and indexing settings.

Keep staging content from becoming the public replacement prematurely. At launch, make sure a staging noindex instruction has not been carried over. Inspect the actual public page rather than treating an administrative setting as sufficient evidence.

5. Connect technical checks with business outcomes

After launch, check important old and new URLs and their redirect paths. Submit the updated sitemap. Monitor indexing and search performance alongside enquiries.

Ranking movement immediately after a change is not conclusive evidence of a technical failure. A reproducible missing page at an important old address is a clearer finding. Fix specific faults first and keep a record of the corrections.

6. Prepare a recovery path

Back up the files, database and configuration your setup uses. Decide who can authorise a rollback and how the previous version will be restored. Confirm access before it is needed.

Where practical, avoid changing the domain, hosting, functionality and every piece of copy simultaneously. A clear scope makes failures and improvements easier to investigate.
