Migration and technical SEO

Migrating or rebuilding the site?

Changing domain, CMS, framework, URL structure or design can alter signals accumulated over time. The delicate part is not launch day itself: it is reaching it with a clear map of what must stay stable.

Before

Capture the current site

URLs, traffic, queries, backlinks, sitemaps and pages that must not be lost.

Launch

Check the new site

Redirects, canonicals, robots, rendering, internal links and HTTP responses verified immediately.

After

Monitor the transition

Errors, coverage, queries and pages checked until the move settles.

What needs continuity

Not every page has the same value. Before launch I identify the parts carrying traffic, links or search signals that should remain connected.

URLs with traffic or backlinks

When they change, they need a relevant destination.

Pages ranking for useful queries

Content and intent should not disappear just because the design changed.

Canonicals and hreflang

They must point to the correct new versions, not staging or obsolete URLs.

Internal links

Menus, breadcrumbs and contextual links can change the weight of important pages.

How I prepare the move

A migration is handled as a system change, not just a visual replacement.

Inventory

Collect URLs, sitemaps, organic landing pages, existing redirects and useful Search Console and analytics data.

Old versus new

Highlight changed URLs, moved content, removed pages and differences in internal structure.

Redirect map

Prepare relevant destinations while avoiding chains and blanket redirects to the homepage.

Staging review

Check canonicals, robots, noindex, sitemaps, structured data and rendering before go-live.

Production check

Immediately after launch, verify the most important URLs and the highest-risk errors.

Checks before and after

The checklist is split because many migration errors can only be prevented before release.
