Answer
SEO preservation during replatforming requires careful planning around URL mapping, redirect strategy, metadata migration, and post-launch monitoring. Website traffic can drop 20-70% after migration if SEO is not handled properly, making this a critical focus area.
URL Mapping and Redirects Every old URL must map to a corresponding new URL using 301 permanent redirects, which signal to search engines that the move is permanent and pass link equity to the new location. A 1:1 redirect map is essential; redirecting all old pages to the homepage destroys rankings. Before migration, audit the current site for broken links, redirect chains, and server errors, fixing issues before moving them to the new platform. Tools like Screaming Frog help identify high-value pages with backlinks that require priority redirect attention.
Content and Technical Preservation Metadata including title tags, meta descriptions, and schema markup must migrate accurately. Internal links should be updated to point to new URLs, and the XML sitemap must be updated and resubmitted to Google Search Console. Post-launch, monitor rankings and traffic using analytics tools to ensure valuable pages are correctly redirected and performing as expected. Regular checks help quickly resolve any issues and preserve accumulated SEO value during the transition.
