Website Migration
Definition and Risk Governance
A Website Migration is the technical transition of a digital platform from one domain, CMS (such as WordPress or Webflow to Next.js), or URL hierarchy to another while safeguarding organic rankings, backlink equity, and conversion tracking across €4,500 to €15,000+ European B2B projects.
Unplanned migrations cause up to 44% organic traffic loss within 90 days. Our SEO services and corporate website teams execute zero-loss transitions. Read our full website migration guide.
Mandatory 301 Redirect and QA Protocol
Successful migrations require a complete pre-launch URL crawl, 1:1 permanent 301 redirect mapping without chains, parity verification of meta tags and Schema.org JSON-LD, and 90-day Google Search Console monitoring.
Protect search equity with technical SEO governance and model post-launch payback using our B2B website redesign ROI guide.
