Website relaunch without SEO losses: the most important checklistPreparation, URL mapping and monitoring decide on a quiet or expensive relaunch
A relaunch often changes URLs, templates, content and navigation simultaneously. A robust process therefore determines before the start which search entries and user paths must be preserved.
Before you switch, create a URL inventory and testable release criteria. After launch, real production responses and search data are part of the follow-up check.
Securing a starting position
Collect important URLs from navigation, sitemap, proprietary search data and known external references. Write down purpose, status, canonical, and the main content available. PDFs and language versions can also be relevant entries.
The new structure should consciously handle every old important user task: content remains, moves, is meaningfully merged or is eliminated. A blanket redirection of all old paths to the start page is not a sufficient plan for this.
A small redirect matrix
| Old URL | Decision | Test criterion |
|---|---|---|
| /services-old/ | Appropriate successor /consultation/ | Direct permanent redirect and corresponding content |
| /advisor-a/ | The URL remains | 200, correct canonical, main content available |
| /Action-2020/ | Not applicable without replacement | Appropriate error status; no old prominent links |
Release before take-off
- Check important page types in the new environment with real example data.
- Test redirect rules with old URLs and intentionally inappropriate control paths.
- Compare titles, canonicals, language references, robots specifications and internal links.
- Check forms, navigation and mobile use.
- Define responsibility and relapse plan for critical failures.
Check again after switching
Go to the actual public addresses. DNS, proxy, cache, and productive environment variables may differ from the test environment. Check especially old entries and unwanted staging locks.
After that, watch accessibility, indexing reports, and important searches. Changes are not attributed to the relaunch alone, without taking into account period and other influences. The title of this guide describes the goal; a completely loss-free course cannot be guaranteed.
Frequent questions
Is a new sitemap enough after the relaunch?
No. It does not replace matching redirects, internal links, correct status codes and the receipt of important content.
How long do you keep old redirects?
As long as old addresses can still be meaningfully accessed or linked, suitable forwardings should not be removed hastily. Observe use and technical maintainability.
