SEO Consultancy for Site Migrations

Migrations — new domain, new platform, or new URLs — are where hard-won rankings quietly vanish, and the numbers back up why teams are right to be nervous: most migrations lose somewhere between 20% and 50% of organic traffic, and without proper redirect mapping, the average recovery timeline runs to roughly 523 days. That's not a rounding error; it's over a year of lost compounding.

The good news is that the loss is largely avoidable, and the research is specific about why it happens: incomplete redirect mapping is consistently the number one cause of post-migration traffic loss, and failing to fully crawl the old site before migrating — capturing every indexed URL, not just the obvious ones — is the second most common mistake. Pre-migration preparation alone accounts for an estimated 60-70% of migration success, because errors in URL mapping or analytics configuration compound irreversibly once the new site is live.

Pre-launch planning, complete redirect mapping, content and technical parity checks, and disciplined post-launch monitoring turn a scary migration into something closer to a non-event — with proper execution, most well-prepared migrations stabilise within 4 to 8 weeks rather than the better part of two years.
