SEO in website migration: Discover the meaning and common pitfalls
SEO in website migration means securing all organic performance when moving a website to a new structure, domain, CMS or design. Used by organizations such as Moz, Google and SEMrush, a secure migration plan is essential to prevent ranking losses, 404 errors and indexation issues. SEO experts like Aleyda Solis and Barry Schwartz emphasize the importance of excellent preparation and monitoring during any website migration.
- Mapping 301 redirects: Make sure all old URLs redirect properly to their new destinations in your new website, for example via a .htaccess file, to retain authority and traffic. A redirect audit with Screaming Frog SEO Spider prevents missed redirects and dead pages.
- Indexation and crawlability testing: Check via Google Search Console that all important pages are crawled and indexed. Wrong canonical tags, popped up noindex directives or forgotten XML sitemaps are classic migration mistakes that will sink rankings.
Which types of website migrations are the riskiest for SEO?
Not every migration is equally impactful. The typical migration types with the highest chance of structural SEO errors are:
- Domain change: For example from www.oude-website.nl to www.nieuwe-website.nl. Without a correct redirect chain you will lose your built-up organic findability in one fell swoop.
- URL structure changes: For example, moving content to other (sub)folders or changing dynamic to static URLs.
- Switching from CMS: Migrations, for example from WordPress to Drupal or vice versa, require extra attention to duplicate content, metadata, technical SEO and canonicalization.
- HTTPS migration: Migrating from HTTP to HTTPS may seem like a formality, but without a strict approach it often leads to mixed content warnings and indexing issues.

Step-by-step plan: Your SEO migration completed without errors
You will achieve a hassle-free SEO migration through a step-by-step and data-driven protocol, recommended by international knowledge authorities such as Google Search Central:
- Inventory all old and new URLs: Use tools like Ahrefs, Screaming Frog, and XML Sitemaps Generator to build a complete overview.
- Run a 301 redirect mapping: Map every old URL to the most relevant new address with permanent 301 redirects, held in a central redirect file.
- Check the technical basis: Make sure robots.txt and canonical tags are correct. Set up temporary staging environments that are shielded from indexing and check crawlability with SEMrush Site Audit or Google Search Console.
- Gather analytics and monitoring tools: Connect the new site to Google Analytics 4, perform a baseline measurement and monitor performance during the transition.
- Test the migration extensively: Use browser plugins and testing tools (such as WebPageTest, Lighthouse, DeepCrawl) to catch critical errors immediately before going live.
- Submit new XML sitemaps and monitor rankings: Upload a fresh sitemap to Search Console, request a 'crawl like Google' and track the position of your most important keywords daily.
